People in the world’s ‘blue zones’ live longer – their diet could hold the key to why

The allure of <a href="https://pubmed.ncbi.nlm.nih.gov/26566891/">eternal youth</a> drives a <a href="https://www.alliedmarketresearch.com/longevity-and-anti-senescence-therapy-market-A14010">multi-billion pound industry</a> ranging from anti-ageing products, supplements and <a href="https://www.everydayhealth.com/diet-nutrition/longevity-diet">diets</a> for those hoping to extend their lifespan.</p> <p>f you look back to the turn of the 20th century, average life expectancy in the UK was around 46 years. Today, it’s closer to <a href="https://population.un.org/wpp/">82 years</a>. We are in fact <a href="https://pubmed.ncbi.nlm.nih.gov/27706136/">living longer than ever before</a>, possibly due to medical advancements and improved <a href="https://www.health.org.uk/publications/reports/mortality-and-life-expectancy-trends-in-the-uk">living and working conditions</a>.</p> <p>But living longer has also come at a price. We’re now seeing higher rates of <a href="https://www.who.int/data/gho/data/themes/mortality-and-global-health-estimates/ghe-leading-causes-of-death">chronic and degenerative diseases</a> – with heart disease consistently topping the list. So while we’re fascinated by what may help us live longer, maybe we should be more interested in being healthier for longer. Improving our “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4632858/">healthy life expectancy</a>” remains a global challenge.</p> <p>Interestingly, certain locations around the world have been discovered where there are a high proportion of centenarians who display remarkable physical and mental health. The <a href="https://pubmed.ncbi.nlm.nih.gov/15489066/">AKEA study of Sardinia, Italy</a>, as example, identified a “blue zone” (named because it was marked with blue pen), where there was a higher number of locals living in the central-eastern mountainous areas who had reached their 100th birthday compared with the wider Sardinian community.</p> <p>This longevity hotspot has since been expanded, and now includes several other areas around the world which also have greater numbers of longer-living, healthy people. Alongside Sardinia, these blue zones are now <a href="https://www.netflix.com/gb/title/81214929">popularly recognised</a> as: Ikaria, Greece; Okinawa, Japan; Nicoya, Costa Rica; and Loma Linda, California.</p> <p>Other than their long lifespans, people living in these zones also appear to share certain other commonalities, which centre around being <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3874460">part of a community</a>, having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4224996/">life purpose</a>, eating <a href="https://pubmed.ncbi.nlm.nih.gov/33514872/">nutritious, healthy foods</a>, keeping <a href="https://www.nature.com/articles/s41398-021-01735-7">stress levels</a> low and undertaking purposeful daily <a href="https://pubmed.ncbi.nlm.nih.gov/30202288/">exercise or physical tasks</a>.</p> <p>Their longevity could also relate to their <a href="https://pubmed.ncbi.nlm.nih.gov/9010380/">environment</a>, being mostly rural (or less polluted), or because of <a href="https://pubmed.ncbi.nlm.nih.gov/22253498/">specific longevity genes</a>.</p> <p>However, studies indicate genetics may only account for <a href="https://pubmed.ncbi.nlm.nih.gov/8786073">around 20-25% of longevity</a> – meaning a person’s lifespan is a complex interaction between lifestyle and genetic factors, which contribute to a long and healthy life.</p> <h2>Is the secret in our diet?</h2> <p>When it comes to diet, each blue zone has its own approach – so one specific food or nutrient does not explain the remarkable longevity observed. But interestingly, a diet rich in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3662288">plant foods</a> (such as locally-grown vegetables, fruits and legumes) does appear to be reasonably consistent across these zones.</p> <p>For instance, the Seventh-day Adventists of Loma Linda are <a href="https://pubmed.ncbi.nlm.nih.gov/10641813/">predominately vegetarian</a>. For centenarians in Okinawa, <a href="https://pubmed.ncbi.nlm.nih.gov/20234038/">high intakes of flavonoids</a> (a chemical compound typically found in plants) from purple sweet potatoes, soy and vegetables, have been linked with <a href="https://pubmed.ncbi.nlm.nih.gov/11710359/">better cardiovascular health</a> – including lower cholesterol levels and lower incidences of stroke and heart disease.</p> <p>In Nicoya, consumption of locally produced rice and beans has been associated with <a href="https://pubmed.ncbi.nlm.nih.gov/34444746/">longer telomere length</a>. Telomeres are the structural part at the end of our chromosomes which protect our genetic material. Our telomeres get shorter each time a cell divides – so get progressively shorter as we age.</p> <p>Certain <a href="https://pubmed.ncbi.nlm.nih.gov/21102320/">lifestyle factors</a> (such as smoking and poor diet) can also shorten telomere length. It’s thought that telomere length acts as a <a href="https://pubmed.ncbi.nlm.nih.gov/31728493/">biomarker of ageing</a> – so having longer telomeres could, in part, be linked with longevity.</p> <p>But a plant-based diet isn’t the only secret. In Sardinia, for example, meat and fish is consumed in moderation in addition to locally grown vegetables and <a href="https://journalofethnicfoods.biomedcentral.com/articles/10.1186/s42779-022-00152-5">traditional foods</a> such as acorn breads, pane carasau (a sourdough flatbread), honey and soft cheeses.</p> <p>Also observed in several blue zone areas is the inclusion of <a href="https://www.jacc.org/doi/10.1016/j.jacc.2021.10.041">olive oil</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/33669360/">wine</a> (in moderation – around 1-2 glasses a day), as well as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3830687/">tea</a>. All of these contain powerful antioxidants which may help <a href="https://ncbi.nlm.nih.gov/pmc/articles/PMC10049696/">protect our cells</a> from damage <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273542/">as we age</a>.</p> <p>Perhaps then, it’s a combination of the protective effects of various nutrients in the diets of these centenarians, which explains their exceptional longevity.</p> <p>Another striking observation from these longevity hot spots is that meals are typically <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7232892">freshly prepared at home</a>. Traditional blue zone diets also don’t appear to contain <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6538973/">ultra-processed foods</a>, fast foods or sugary drinks which may <a href="https://pubmed.ncbi.nlm.nih.gov/32330232/">accelerate ageing</a>. So maybe it’s just as important to consider what these longer-living populations are not doing, as much as what they are doing.</p> <p>There also appears to be a pattern of eating until 80% full (in other words partial <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9036399/">caloric reduction</a>. This could be important in also supporting how our cells deal with damage as we age, which could mean a longer life.</p> <p>Many of the factors making up these blue zone diets – primarily plant-based and natural whole foods – are associated with <a href="https://pubmed.ncbi.nlm.nih.gov/35706591/">lower risk of chronic diseases</a> such as <a href="https://pubmed.ncbi.nlm.nih.gov/28728684/">heart disease</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/37589638/">cancer</a>. Not only could such diets contribute to a <a href="https://pubmed.ncbi.nlm.nih.gov/37836577/">longer, healthier life</a>, but could support a more <a href="https://pubmed.ncbi.nlm.nih.gov/33397404/">diverse gut microbiome</a>, which is also associated with healthy ageing.</p> <p>Perhaps then we can learn something from these remarkable centenarians. While diet is only one part of the bigger picture when it comes to longevity, it’s an area we can do something about. In fact, it might just be at the heart of improving not only the quality of our health, but the quality of how we age.<!-- Below is The Conversation's page counter tag.

Does intermittent fasting have benefits for our brain?

<p><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <em><a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>Intermittent fasting has become a popular dietary approach to help people lose or manage their <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8683964/">weight</a>. It has also been promoted as a way to reset metabolism, control chronic disease, slow ageing and <a href="https://pubmed.ncbi.nlm.nih.gov/27810402">improve overall health</a>.</p> <p>Meanwhile, some research suggests intermittent fasting may offer a different way for the brain to access energy and provide protection against neurodegenerative diseases like <a href="https://link.springer.com/article/10.1007/s11011-023-01288-2">Alzheimer’s disease</a>.</p> <p>This is not a new idea – the ancient Greeks believed fasting <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8839325/">enhanced thinking</a>. But what does the modern-day evidence say?</p> <h2>First, what is intermittent fasting?</h2> <p>Our <a href="https://pubmed.ncbi.nlm.nih.gov/35487190/">diets</a> – including calories consumed, macronutrient composition (the ratios of fats, protein and carbohydrates we eat) and when meals are consumed – are factors in our lifestyle we can change. People do this for cultural reasons, desired weight loss or potential health gains.</p> <p>Intermittent fasting consists of short periods of calorie (energy) restriction where food intake is limited for 12 to 48 hours (usually 12 to 16 hours per day), followed by periods of normal food intake. The intermittent component means a re-occurrence of the pattern rather than a “one off” fast.</p> <p>Food deprivation beyond 24 hours typically constitutes starvation. This is distinct from fasting due to its specific and potentially harmful biochemical alterations and nutrient deficiencies if continued for long periods.</p> <h2>4 ways fasting works and how it might affect the brain</h2> <p>The brain accounts for about <a href="https://theconversation.com/how-much-energy-do-we-expend-thinking-and-using-our-brain-197990">20% of the body’s energy consumption</a>.</p> <p>Here are four ways intermittent fasting can act on the body which could help explain its potential effects on the brain.</p> <p><strong>1. Ketosis</strong></p> <p>The goal of many intermittent fasting routines is to flip a “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5913738/">metabolic switch</a>” to go from burning predominately carbohydrates to burning fat. This is called ketosis and typically occurs after 12–16 hours of fasting, when liver and glycogen stores are depleted. <a href="https://www.ncbi.nlm.nih.gov/books/NBK493179/">Ketones</a> – chemicals produced by this metabolic process – become the preferred energy source for the brain.</p> <p>Due to this being a slower metabolic process to produce energy and potential for lowering blood sugar levels, ketosis can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10844723/">cause symptoms</a> of hunger, fatigue, nausea, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8754590/">low mood</a>, irritability, constipation, headaches, and brain “fog”.</p> <p>At the same time, as glucose metabolism in the brain declines with ageing, studies have shown ketones could provide an alternative energy source to <a href="https://www.science.org/doi/10.1126/science.aau2095">preserve brain function</a> and prevent <a href="https://pubmed.ncbi.nlm.nih.gov/32709961/">age-related neurodegeneration disorders and cognitive decline</a>.</p> <p>Consistent with this, increasing ketones through <a href="https://pubmed.ncbi.nlm.nih.gov/31027873/">supplementation</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/31757576/">diet</a> has been shown to improve cognition in adults with mild cognitive decline and those at risk of Alzheimer’s disease respectively.</p> <p><strong>2. Circadian syncing</strong></p> <p>Eating at times that <a href="https://pubmed.ncbi.nlm.nih.gov/32480126/">don’t match our body’s natural daily rhythms</a> can disrupt how our organs work. Studies in shift workers have suggested this might also make us more prone to <a href="https://pubmed.ncbi.nlm.nih.gov/22010477/">chronic disease</a>.</p> <p>Time-restricted eating is when you eat your meals within a six to ten-hour window during the day when you’re most active. Time-restricted eating causes changes in <a href="https://pubmed.ncbi.nlm.nih.gov/36599299/">expression of genes in tissue</a> and helps the body during rest and activity.</p> <p>A 2021 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7827225/">study of 883 adults</a> in Italy indicated those who restricted their food intake to ten hours a day were less likely to have cognitive impairment compared to those eating without time restrictions.</p> <p><strong>3. Mitochondria</strong></p> <p>Intermittent fasting may provide <a href="https://pubmed.ncbi.nlm.nih.gov/35218914/">brain protection</a> through improving mitochondrial function, metabolism and reducing oxidants.</p> <p>Mitochondria’s <a href="https://www.genome.gov/genetics-glossary/Mitochondria">main role is to produce energy</a> and they are crucial to brain health. Many age-related diseases are closely related to an energy supply and demand imbalance, likely attributed to <a href="https://www.nature.com/articles/s41574-021-00626-7">mitochondrial dysfunction during ageing</a>.</p> <p>Rodent studies suggest alternate day fasting or reducing calories <a href="https://journals.sagepub.com/doi/10.1038/jcbfm.2014.114">by up to 40%</a> might protect or improve <a href="http://www.ncbi.nlm.nih.gov/pubmed/21861096">brain mitochondrial function</a>. But not all studies support this theory.</p> <p><strong>4. The gut-brain axis</strong></p> <p>The <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6469458/">gut and the brain communicate with each other</a> via the body’s nervous systems. The brain can influence how the gut feels (think about how you get “butterflies” in your tummy when nervous) and the gut can affect mood, cognition and mental health.</p> <p>In mice, intermittent fasting has shown promise for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5913738/">improving brain health</a> by increasing survival and <a href="https://pubmed.ncbi.nlm.nih.gov/12354284/">formation of neurons</a> (nerve cells) in the hippocampus brain region, which is involved in memory, learning and emotion.</p> <p>There’s <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8470960/">no clear evidence</a> on the effects of intermittent fasting on cognition in healthy adults. However one 2022 study interviewed 411 older adults and found <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9646955/">lower meal frequency</a> (less than three meals a day) was associated with reduced evidence of Alzheimer’s disease on brain imaging.</p> <p>Some research has suggested calorie restriction may have a protective effect against <a href="https://academic.oup.com/nutritionreviews/article/81/9/1225/7116310">Alzheimer’s disease</a> by reducing oxidative stress and inflammation and promoting vascular health.</p> <p>When we look at the effects of overall energy restriction (rather than intermittent fasting specifically) the evidence is mixed. Among people with mild cognitive impairment, one study showed <a href="https://pubmed.ncbi.nlm.nih.gov/26713821/">cognitive improvement</a> when participants followed a calorie restricted diet for 12 months.</p> <p>Another study found a 25% calorie restriction was associated with <a href="https://pubmed.ncbi.nlm.nih.gov/30968820">slightly improved working memory</a> in healthy adults. But a <a href="https://www.sciencedirect.com/science/article/pii/S0022316623025221?via%3Dihub">recent study</a>, which looked at the impact of calorie restriction on spatial working memory, found no significant effect.</p> <h2>Bottom line</h2> <p>Studies in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9740746/">mice</a> support a role for intermittent fasting in improving brain health and ageing, but few studies in humans exist, and the evidence we have is mixed.</p> <p>Rapid weight loss associated with calorie restriction and intermittent fasting can lead to nutrient deficiencies, muscle loss, and decreased immune function, particularly in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8749464/">older adults</a> whose nutritional needs may be higher.</p> <p>Further, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6314618/">prolonged fasting</a> or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9042193/">severe calorie restriction</a> may pose risks such as fatigue, dizziness, and electrolyte imbalances, which could exacerbate existing health conditions.</p> <p>If you’re considering <a href="https://www.nejm.org/doi/10.1056/NEJMra1905136?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">intermittent fasting</a>, it’s best to seek advice from a health professional such as a dietitian who can provide guidance on structuring fasting periods, meal timing, and nutrient intake. This ensures intermittent fasting is approached in a safe, sustainable way, tailored to individual needs and goals.<!-- Below is The Conversation's page counter tag.

Mothers’ dieting habits and self-talk have profound impact on daughters − 2 psychologists explain how to cultivate healthy behaviors and body image

<p><em><a href="https://theconversation.com/profiles/janet-j-boseovski-451496">Janet J.

We provide information on how to build a foundation for healthy body image beginning in girlhood.</p> <h2>Culturally defined body ideals</h2> <p>Given the strong influence of social media and other cultural influences on body ideals, it’s understandable that so many people pursue diets aimed at weight loss. <a href="https://communityhealth.mayoclinic.org/featured-stories/tiktok-diets">TikTok</a>, YouTube, Instagram and celebrity websites feature slim influencers and “how-tos” for achieving those same results in no time.</p> <p>For example, women and teens are engaging in rigid and extreme forms of exercise such as 54D, a program to <a href="https://54d.com/">achieve body transformation in 54 days</a>, or the <a href="https://health.clevelandclinic.org/75-hard-challenge-and-rules">75 Hard Challenge</a>, which is to follow five strict rules for 75 days.</p> <p>For teens, these pursuits are likely fueled by trendy body preoccupations such as the desire for “<a href="https://www.nytimes.com/2024/02/06/well/move/tiktok-legging-legs-eating-disorders.html">legging legs</a>.”</p> <p>Women and teens have also been been inundated with recent messaging around <a href="https://theconversation.com/drugs-that-melt-away-pounds-still-present-more-questions-than-answers-but-ozempic-wegovy-and-mounjaro-could-be-key-tools-in-reducing-the-obesity-epidemic-205549">quick-fix weight loss drugs</a>, which come with a lot of caveats.</p> <p>Dieting and weight loss goals are highly individual, and when people are intensely self-focused, it is <a href="https://doi.org/10.1521/jscp.2000.19.1.70">possible to lose sight of the bigger picture</a>. Although women might wonder what the harm is in trying the latest diet, science shows that dieting behavior doesn’t just affect the dieter. In particular, for women who are mothers or who have other girls in their lives, these behaviors affect girls’ emerging body image and their health and well-being.</p> <h2>The profound effect of maternal role models</h2> <p>Research shows that mothers and maternal figures <a href="https://doi.org/10.1016/j.brat.2017.11.001">have a profound influence on their daughters’ body image</a>.</p> <p>The opportunity to influence girls’ body image comes far earlier than adolescence. In fact, research shows that these influences on body image <a href="https://www.teenvogue.com/story/how-toxic-diet-culture-is-passed-from-moms-to-daughters">begin very early in life</a> – <a href="https://doi.org/10.1016/bs.acdb.2016.10.006">during the preschool years</a>.</p> <p>Mothers may feel that they are being discreet about their dieting behavior, but little girls are watching and listening, and they are far more observant of us than many might think.</p> <p>For example, one study revealed that compared with daughters of nondieting women, 5-year-old girls whose mothers dieted <a href="https://doi.org/10.1016/S0002-8223(00)00339-4">were aware of the connection between dieting and thinness</a>.</p> <p>Mothers’ eating behavior does not just affect girls’ ideas about dieting, but also their daughters’ eating behavior. The amount of food that mothers eat <a href="https://doi.org/10.1016/j.appet.2018.04.018">predicts how much their daughters will eat</a>. In addition, daughters whose mothers are dieters are <a href="https://doi.org/10.1016/j.appet.2018.04.018">more likely to become dieters themselves</a> and are also <a href="https://doi.org/10.1016/j.eatbeh.2007.03.001">more likely to have a negative body image</a>.</p> <p>Negative body image is <a href="https://theconversation.com/mounting-research-documents-the-harmful-effects-of-social-media-use-on-mental-health-including-body-image-and-development-of-eating-disorders-206170">not a trivial matter</a>. It affects girls’ and women’s mental and physical well-being in a <a href="https://doi.org/10.1177/1359105317710815">host of ways</a> and <a href="https://doi.org/10.1016/j.brat.2011.06.009">can predict the emergence of eating disorders</a>.</p> <h2>Avoiding ‘fat talk’</h2> <p>What can moms do, then, to serve their daughters’ and their own health?</p> <p>They can focus on small steps. And although it is best to begin these efforts early in life – in girlhood – it is never too late to do so.</p> <p>For example, mothers can consider how they think about and talk about themselves around their daughters. Engaging in “fat talk” may inadvertently send their daughters the message that larger bodies are bad, <a href="https://doi.org/10.1016/j.bodyim.2020.07.004">contributing to weight bias</a> and negative self-image. Mothers’ fat talk also <a href="https://doi.org/10.1080/15267431.2021.1908294">predicts later body dissatisfaction in daughters</a>.</p> <p>And negative self-talk isn’t good for mothers, either; it is associated with <a href="https://doi.org/10.1177/1359105318781943">lower motivation and unhealthful eating</a>. Mothers can instead practice and model self-compassion, which involves treating oneself the way <a href="https://doi.org/10.1016/j.bodyim.2016.03.003">a loving friend might treat you</a>.</p> <p>In discussions about food and eating behavior, it is important to avoid moralizing certain kinds of food by labeling them as “good” or “bad,” as girls may extend these labels to their personal worth. For example, a young girl may feel that she is being “bad” if she eats dessert, if that is what she has learned from observing the women around her. In contrast, she may feel that she has to eat a salad to be “good.”</p> <p>Moms and other female role models can make sure that the dinner plate sends a healthy message to their daughters by showing instead that all foods can fit into a balanced diet when the time is right. Intuitive eating, which emphasizes paying attention to hunger and satiety and allows flexibility in eating behavior, is associated with <a href="https://doi.org/10.1007/s40519-020-00852-4">better physical and mental health in adolescence</a>.</p> <p>Another way that women and especially moms can buffer girls’ body image is by helping their daughters <a href="https://doi.org/10.1016/j.bodyim.2021.12.009">to develop media literacy</a> and to think critically about the nature and purpose of media. For example, moms can discuss the misrepresentation and distortion of bodies, such as the use of filters to enhance physical appearance, on social media.</p> <h2>Focusing on healthful behaviors</h2> <p>One way to begin to focus on health behaviors rather than dieting behaviors is to develop respect for the body and to <a href="https://theconversation.com/body-neutrality-what-it-is-and-how-it-can-help-lead-to-more-positive-body-image-191799">consider body neutrality</a>. In other words, prize body function rather than appearance and spend less time thinking about your body’s appearance. Accept that there are times when you may not feel great about your body, and that this is OK.</p> <p>To feel and look their best, mothers can aim to stick to a <a href="https://theconversation.com/whats-the-best-diet-for-healthy-sleep-a-nutritional-epidemiologist-explains-what-food-choices-will-help-you-get-more-restful-zs-219955">healthy sleep schedule</a>, manage their stress levels, <a href="https://theconversation.com/fiber-is-your-bodys-natural-guide-to-weight-management-rather-than-cutting-carbs-out-of-your-diet-eat-them-in-their-original-fiber-packaging-instead-205159">eat a varied diet</a> that includes all of the foods that they enjoy, and <a href="https://theconversation.com/the-runners-high-may-result-from-molecules-called-cannabinoids-the-bodys-own-version-of-thc-and-cbd-170796">move and exercise their bodies regularly</a> as lifelong practices, rather than engaging in quick-fix trends.</p> <p>Although many of these tips sound familiar, and perhaps even simple, they become effective when we recognize their importance and begin acting on them. Mothers can work toward modeling these behaviors and tailor each of them to their daughter’s developmental level. It’s never too early to start.</p> <h2>Promoting healthy body image</h2> <p>Science shows that several personal characteristics are associated with body image concerns among women.</p> <p>For example, research shows that women who are <a href="https://doi.org/10.1016/j.bodyim.2020.02.001">higher in neuroticism</a> <a href="https://doi.org/10.1186/2050-2974-1-2">and perfectionism</a>, <a href="https://doi.org/10.3389/fpsyg.2022.983534">lower in self-compassion</a> or <a href="https://doi.org/10.1016/j.bodyim.2013.08.001">lower in self-efficacy</a> are all more likely to struggle with negative body image.</p> <p>Personality is frequently defined as a person’s characteristic pattern of thoughts, feelings and behaviors. But if they wish, <a href="https://doi.org/10.1002/per.1945">mothers can change personality characteristics</a> that they feel aren’t serving them well.</p> <p>For example, perfectionist tendencies – such as setting unrealistic, inflexible goals – can be examined, challenged and replaced with more rational thoughts and behaviors. A woman who believes she must work out every day can practice being more flexible in her thinking. One who thinks of dessert as “cheating” can practice resisting moral judgments about food.</p> <p>Changing habitual ways of thinking, feeling and behaving certainly takes effort and time, but it is far more likely than diet trends to bring about sustainable, long-term change. And taking the first steps to modify even a few of these habits can positively affect daughters.</p> <p>In spite of all the noise from media and other cultural influences, mothers can feel empowered knowing that they have a significant influence on their daughters’ feelings about, and treatment of, their bodies.</p> <p>In this way, mothers’ modeling of healthier attitudes and behaviors is a sound investment – for both their own body image and that of the girls they love.<!-- Below is The Conversation's page counter tag.

The best diet for 2024

<p>Over years of research and diet rankings, there is one regimen that scientists have crowned the "Best Diet Overall" for seven years in a row. </p> <p>The Mediterranean diet has topped the list in <a href="https://health.usnews.com/best-diet/best-diets-overall" target="_blank" rel="noopener"><em>US News and World Reports’</em></a> annual ranking for 2024, followed by the DASH diet, and the MIND diet coming in third.  </p> <p>The ranking is based off the findings of a panel of leading medical and nutrition experts, who analyse the nutritional completeness, health risks and benefits, long-term sustainability and  effectiveness of the diet in addressing its goals. </p> <p><strong>What sets it apart from other diets? </strong></p> <p>The Mediterranean diet emphasises multiple servings of fruits and vegetables daily, alongside whole grains, legumes, nuts, olive oil and seafood. </p> <p>Red meats, dairy and poultry are consumed occasionally and in moderation, and highly processed foods and added sugars are generally avoided. </p> <h4><strong>What are its benefits?</strong></h4> <p>The experts found that following the diet long term can increase the odds of living a longer, healthier life, with a few other studies suggesting it lowers the risk of heart disease and Type 2 diabetes, while potentially slowing cognitive decline.</p> <p>“It’s a way of life, it’s a cuisine, it dates back thousands of years, and in the last five to six decades, it is the most highly researched cuisine in the world,” said Dr Catherine Itsiopoulos, a professor of nutrition and dietetics at RMIT University in Melbourne.</p> <p><strong>Lowers risk of heart disease</strong></p> <p>A 2021 research review found that the diet has been shown to reduce the risk of coronary heart disease in women by 29 per cent and stroke by 13 per cent. </p> <p>A 2017 analysis found that on average it lowers the risk of coronary heart disease, heart attacks and strokes by 40 per cent. </p> <p>Experts suggest that this may be because  the fats in olive oil, seeds, fish and nuts are monounsaturated or polyunsaturated fats aka healthy fats. </p> <p>Additionally, because of its emphasis on fruits, vegetables and legumes, which contain antioxidants and other beneficial compounds, it is believed to combat chronic inflammation. </p> <p><strong>Lowers chances of developing type 2 diabetes </strong></p> <p>Because this diet relies heavily on honey and cinnamon as sweeteners, and fruits as a primary source of sugar, it reduces the risk of developing this disease. </p> <p>One study conducted on 300,000 participants found that those who were on the Mediterranean diet had a nearly 30 per cent lower risk of Type 2 diabetes. </p> <p><strong>Good for your gut</strong></p> <p>The diet contains a lot of fibre which are associated with more regular bowel movements, lower blood pressure, cholesterol and blood sugar levels, according to the Food and Drug Administration.</p> <p>This is because good bacteria in our stomachs feed off fibre, which creates a stronger lining in the intestines. </p> <p>There are a few other potential health benefits including reducing risk of dementia among seniors by almost 25 per cent, and lowering the risk of death from cancer including breast, colorectal, head and neck and lung cancers. </p> <p>See the full list <a href="https://health.usnews.com/best-diet/best-diets-overall" target="_blank" rel="noopener">here</a>. </p> <p><em>Image: Getty</em></p> <p> </p>

How dieting, weight suppression and even misuse of drugs like Ozempic can contribute to eating disorders

<p><em><a href="https://theconversation.com/profiles/samantha-withnell-1504436">Samantha Withnell</a>, <a href="https://theconversation.com/institutions/western-university-882">Western University</a> and <a href="https://theconversation.com/profiles/lindsay-bodell-1504260">Lindsay Bodell</a>, <a href="https://theconversation.com/institutions/western-university-882">Western University</a></em></p> <p>Up to 72 per cent of women and 61 per cent of men are dissatisfied with their weight or <a href="https://doi.org/10.1016/j.eatbeh.2014.04.010">body image</a>, according to a U.S. study. Globally, millions of people <a href="https://doi.org/10.1111%2Fobr.12466">attempt to lose weight</a> every year with the hope that weight loss will have positive effects on their body image, health and quality of life.</p> <p>However, these motivated individuals often struggle to maintain new diets or exercise regimens. The rise of medications such as semaglutides, like <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101298">Ozempic</a> or <a href="https://dhpp.hpfb-dgpsa.ca/dhpp/resource/101765">Wegovy</a>, <a href="https://www.cbc.ca/news/health/ozempic-weight-loss-1.6772021">might be viewed as an appealing “quick fix”</a> alternative to meet weight loss goals.</p> <p>Research led by our team and others suggests that such attempts to lose weight often do more harm than good, and even increase the risk of <a href="https://osf.io/9stq2">developing an eating disorder</a>.</p> <h2>Weight loss and eating disorders</h2> <p>Eating disorders are <a href="https://doi.org/10.1002/eat.20589">serious mental health conditions</a> primarily characterized by extreme patterns of under- or over-eating, concerns about one’s shape or body weight or other behaviours intended to influence body shape or weight such as exercising excessively or self-inducing vomiting.</p> <p>Although once thought to only affect young, white adolescent girls, eating disorders do not discriminate; eating disorders can develop in people of <a href="https://doi.org/10.1002/erv.2553">any age, sex, gender or racial/ethnic background</a>, with an estimated <a href="https://nedic.ca/general-information/">one million Canadians</a> suffering from an eating disorder at any given time. Feb. 1 to 7 is <a href="https://nedic.ca/edaw/">National Eating Disorders Awareness Week</a>.</p> <p>As a clinical psychologist and clinical psychology graduate student, our research has focused on how eating disorders develop and what keeps them going. Pertinent to society’s focus on weight-related goals, our research has examined associations between weight loss and eating disorder symptoms.</p> <h2>Eating disorders and ‘weight suppression’</h2> <p>In eating disorders research, the state of maintaining weight loss is referred to as “weight suppression.” Weight suppression is typically defined as the difference between a person’s current weight and their highest lifetime weight (excluding pregnancy).</p> <p>Despite the belief that weight loss will improve body satisfaction, we found that in a sample of over 600 men and women, weight loss had no impact on women’s negative body image and was associated with increased body dissatisfaction in <a href="https://doi.org/10.1016/j.bodyim.2023.01.011">men</a>. Importantly, being more weight suppressed has been associated with the <a href="https://doi.org/10.1093/ajcn/nqaa146">onset of eating disorders</a>, including anorexia nervosa and bulimia nervosa.</p> <p><a href="https://doi.org/10.1007/s11920-018-0955-2">One proposed explanation</a> for the relationship between weight suppression and eating disorders is that maintaining weight loss becomes increasingly difficult as body systems that <a href="https://doi.org/10.3945/ajcn.110.010025">reduce metabolic rate and energy expenditure, and increase appetite</a>, are activated to promote weight gain.</p> <p>There is growing awareness that <a href="https://doi.org/10.1136/bmj.g2646">weight regain is highly likely following conventional diet programs</a>. This might lead people to engage in more and more extreme behaviours to control their weight, or they might shift between extreme restriction of food intake and episodes of overeating or binge eating, the characteristic symptoms of bulimia nervosa.</p> <h2>Ozempic and other semaglutide drugs</h2> <p>Semaglutide drugs like Ozempic and Wegovy are part of a class of drug called <a href="https://pdf.hres.ca/dpd_pm/00067924.PDF">glucagon-like peptide-1 agonists (GLP-1As)</a>. These drugs work by mimicking the hormone GLP-1 to interact with neural pathways that signal satiety (fullness) and slow stomach emptying, leading to reduced food intake.</p> <p>Although GLP-1As are indicated to treat Type 2 diabetes, <a href="https://www.cbc.ca/news/canada/london/ozempic-off-label-1.6884141">they are increasingly prescribed off-label</a> or being <a href="https://www.bbc.com/news/health-67414203">illegally purchased</a> without a prescription because of their observed effectiveness at inducing weight loss. Although medications like Ozempic do often lead to weight loss, the rate of weight loss may <a href="https://doi.org/10.1001/jama.2021.3224">slow down or stop over time</a>.</p> <p>Research by Lindsay Bodell, one of the authors of this story, and her colleagues on weight suppression may help explain why effects of semaglutides diminish over time, as <a href="https://doi.org/10.1016/j.physbeh.2019.112565">weight suppression is associated with reduced GLP-1 response</a>. This means those suppressing their weight could become less responsive to the satiety signals activated by GLP-1As.</p> <p>Additionally, weight loss effects are only seen for as long as the medication is taken, meaning those who take these drugs to achieve some weight loss goal are <a href="https://doi.org/10.1111/dom.14725">likely to regain most, if not all, weight lost</a> when they stop taking the medication.</p> <h2>Risks of dieting and weight-loss drugs</h2> <p>The growing market for off-label weight loss drugs is concerning, because of the exacerbation of <a href="https://theconversation.com/ozempic-the-miracle-drug-and-the-harmful-idea-of-a-future-without-fat-211661">weight stigma</a> and the serious <a href="https://doi.org/10.1016/j.jand.2022.01.004">health risks</a> associated with unsupervised weight loss, including developing eating disorders.</p> <p>Researchers and health professionals are already raising the alarm about the use of GLP-1As in children and adolescents, due to concerns about their possible <a href="https://doi.org/10.1017/cts.2023.612">impact on growth and development</a>.</p> <p>Moreover, popular weight-loss methods, whether they involve pills or “crash diets,” often mimic symptoms of eating disorders. For example, intermittent fasting diets that involve long periods of fasting followed by short periods of food consumption may mimic and <a href="https://doi.org/10.1016/j.eatbeh.2022.101681">increase the risk of developing binge eating problems</a>.</p> <p>The use of diet pills or laxatives to lose weight has been found to increase the risk of <a href="https://doi.org/10.2105/AJPH.2019.305390">being diagnosed with an eating disorder in the next one to three years</a>. Drugs like Ozempic may also be <a href="https://doi.org/10.1002/eat.24109">misused by individuals already struggling with an eating disorder</a> to suppress their appetite, compensate for binge eating episodes or manage fear of weight gain.</p> <p>Individuals who are already showing signs of an eating disorder, such as limiting their food intake and intense concerns about their weight, may be most at risk of spiralling from a weight loss diet or medication into an eating disorder, <a href="https://doi.org/10.1002/eat.24116">even if they only lose a moderate amount of weight</a>.</p> <p>People who are dissatisfied with their weight or have made multiple attempts to lose weight often feel pressured to try increasingly drastic methods. However, any diet, exercise program or weight-loss medication promising a quick fix for weight loss should be treated with extreme caution. At best, you may gain the weight back; at worst, you put yourself at risk for much more serious eating disorders and other health problems.<!-- Below is The Conversation's page counter tag.

Is your diet giving you headaches?

<p><strong>Diet-induced headaches</strong></p> <p>If you’re searching for the cause of that niggling headache, it’s possible that what you’re eating – or drinking – could be to blame.</p> <p><strong>Stop over-restricting your kilojoule intake</strong></p> <p>Spacing your meals too far apart or eating at irregular intervals causes a dip in blood-glucose levels, which drives your body into starvation mode. This triggers a cascade of hormones and brain chemicals similar to your body’s response to stress, which can bring on headaches. Once you fuel up, the headache should go away.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> You should wait no more than four hours between meals. Try light snacks between meals, such as a handful of almonds.</p> <p><strong>Stay hydrated </strong></p> <p>Dehydration is a common headache trigger. Experts suspect it may have to do with narrowing of blood vessels in the brain, which reduces the brain’s supply of blood and oxygen. Not getting sufficient electrolytes may also contribute to headaches.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> By the time you feel thirsty, your body is already a little dehydrated, so rehydrate often. Have a glass of water with every meal and between meals.</p> <p><strong>Avoid artificial sweeteners</strong></p> <p>Some people may be particularly sensitive to aspartame, which can lead to headaches, according to a US study. Aspartame can be in diet drinks as well as foods.</p> <p><span style="text-decoration: underline;"><em>Tip:</em></span> If you suspect artificial sweeteners may be triggering your headaches, keep a food journal to watch for patterns.</p> <p><strong>Cut caffeine slowly</strong></p> <p>If you’ve ditched fizzy drinks or coffee, you may be experiencing caffeine withdrawal.

I’m trying to lose weight and eat healthily. Why do I feel so hungry all the time? What can I do about it?

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Benjamin Franklin, one of the founding fathers of the United States, famously said nothing is certain except death and taxes. But I think we can include “you’ll feel hungry when you’re trying to lose weight” as another certainty.</p> <p>The reason is basic biology. So how does this work – and what can you do about it?</p> <h2>Hormones control our feelings of hunger</h2> <p>Several hormones play an essential role in regulating our feelings of hunger and fullness. The most important are ghrelin – often called the hunger hormone – and leptin.</p> <p>When we’re hungry, <a href="https://pubmed.ncbi.nlm.nih.gov/11739476/">ghrelin</a> is released by our stomach, lighting up a part of our brain called the hypothalamus to tell us to eat.</p> <p>When it’s time to stop eating, hormones, including <a href="https://pubmed.ncbi.nlm.nih.gov/8717038/">leptin</a>, are released from different organs, such as our gut and fat tissue, to signal to the brain that we’re full.</p> <h2>Dieting disrupts the process</h2> <p>But when we change our diet and start losing weight, we disrupt how these <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">appetite hormones function</a>.</p> <p>This triggers a process that stems from our hunter-gatherer ancestors. Their bodies developed this mechanism as a survival response to adapt to periods of deprivation and protect against starvation.</p> <p>The levels of hormones <a href="https://pubmed.ncbi.nlm.nih.gov/23126426/">managing our hunger increase</a>, making us feel hungrier to tell us to eat more, while the ones responsible for signalling we’re full decrease their levels, intensifying our feelings of hunger.</p> <p>We end up increasing our calorie consumption so we eat more to regain the weight we lost.</p> <p>But worse, even after the kilos creep back on, <a href="https://pubmed.ncbi.nlm.nih.gov/22029981/">our appetite hormones don’t restore</a> to their normal levels – they keep telling us to eat more so we put on a little extra fat. This is our body’s way of preparing for the next bout of starvation we will impose through dieting.</p> <p>Fortunately, there are things we can do to manage our appetite, including:</p> <h2>1. Eating a large, healthy breakfast every day</h2> <p>One of the easiest ways to manage our feelings of hunger throughout the day is to eat most of our food earlier in the day and taper our meal sizes so dinner is the smallest meal.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> shows a low-calorie or small breakfast leads to increased feelings of hunger, specifically appetite for sweets, across the course of the day.</p> <p><a href="https://www.cell.com/cell-metabolism/fulltext/S1550-4131(22)00344-8">Another study</a> found the same effect. Participants went on a calorie-controlled diet for two months, where they ate 45% of their calories for breakfast, 35% at lunch and 20% at dinner for the first month, before switching to eat their largest meal in the evening and their smallest in the morning. Eating the largest meal at breakfast resulted in decreased hunger throughout the day.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/32073608/">Research</a> also shows we burn the calories from a meal 2.5-times more efficiently in the morning than the evening. So emphasising breakfast over dinner is good not just for hunger control, but also weight management.</p> <h2>2. Prioritising protein</h2> <p>Protein helps contain feelings of hunger. This is because protein-rich foods such as lean meats, tofu and beans suppress the appetite-stimulating ghrelin and stimulate another hormone called <a href="https://www.sciencedirect.com/science/article/pii/S1550413106002713">peptide YY</a> that makes you feel full.</p> <p>And just as eating a breakfast is vital to managing our hunger, what we eat is important too, with <a href="https://pubmed.ncbi.nlm.nih.gov/24703415/">research</a> confirming a breakfast containing protein-rich foods, such as eggs, will leave us feeling fuller for longer.</p> <p>But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado.</p> <h2>3. Filling up with nuts and foods high in good fats and fibre</h2> <p>Nuts often get a bad rap – thanks to the misconception they cause weight gain – but nuts can help us manage our hunger and weight. The filling fibre and good fats found in nuts take longer to digest, meaning our hunger is satisfied for longer.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/12791613/">Studies</a> suggest you can include up to 68 grams per day of nuts without affecting your weight.</p> <p>Avocados are also high in fibre and heart-healthy monounsaturated fats, making them another excellent food for managing feelings of fullness. This is backed by a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6567160/">study</a> confirming participants who ate a breakfast incorporating avocado felt more satisfied and less hungry than participants who ate a meal containing the same calories but with lower fat and fibre content.</p> <p>Similarly, eating foods that are high in soluble fibre – such as <a href="https://pubmed.ncbi.nlm.nih.gov/24820437/">beans</a> and vegetables – make us feel fuller. This type of fibre attracts water from our gut, forming a gel that slows digestion.</p> <h2>4. Eating mindfully</h2> <p>When we take time to really be aware of and enjoy the food we’re eating, we slow down and eat far less.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/28718396/">review</a> of 68 studies found eating mindfully helps us better recognise feelings of fullness. Mindful eating provides our brain enough time to recognise and adapt to the signals from our stomach telling us we’re full.</p> <p>Slow down your food consumption by sitting at the dinner table and use smaller utensils to reduce the volume of food you eat with each mouthful.</p> <h2>5. Getting enough sleep</h2> <p>Sleep deprivation disturbs our <a href="https://www.sciencedirect.com/science/article/abs/pii/S1389945708700133">appetite hormones</a>, increasing our feelings of hunger and <a href="https://www.nature.com/articles/ncomms3259">triggering cravings</a>. So aim to get at least seven hours of uninterrupted sleep a night.</p> <p>Try switching off your devices <a href="https://journals.sagepub.com/doi/full/10.1177/1477153515584979">two hours before bed</a> to boost your body’s secretion of sleep-inducing hormones like melatonin.</p> <h2>6. Managing stress</h2> <p>Stress increases our <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">body’s production of cortisol</a> and triggers food cravings.</p> <p>So take time out when you need it and set aside time for stress-relieving activities. This can be as simple as getting outdoors. A <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00722/full">2019 study</a> found sitting or walking outdoors at least three times a week could reduce cortisol levels by 21%.</p> <h2>7. Avoiding depriving ourselves</h2> <p>When we change our diet to lose weight or eat healthier, we typically restrict certain foods or food groups.</p> <p>However, this <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">heightens activity</a> in our mesocorticolimbic circuit – the reward system part of the brain – often resulting in us craving the foods we’re trying to avoid. Foods that give us pleasure release feel-good chemicals called endorphins and learning chemicals called dopamine, which enable us to remember – and give in to – that feel-good response.</p> <p>When we change our diet, activity in our hypothalamus – the clever part of the brain that regulates emotions and food intake – <a href="https://pubmed.ncbi.nlm.nih.gov/18568078/">also reduces</a>, decreasing our control and judgement. It often triggers a psychological response dubbed the “what-the-hell effect”, when we indulge in something we think we shouldn’t feel guilty about and then go back for even more.</p> <p>Don’t completely cut out your favourite foods when you go on a diet or deprive yourself if you’re hungry. It will take the pleasure out of eating and eventually you’ll give into your cravings.</p> <p><em>At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

When it comes to weight, your ‘diet’ is much more than what you eat

<p>Atkins, keto, palaeo, gluten-free, low-carb, low-fat, high-fat, raw, vegan, vego, pescatarian – phew, that’s a lot of different diets!</p> <div class="copy"> <p>And it’s by no means an exhaustive list.</p> <p>The old adage ‘you are what you eat’ has come to be a mantra for good diet and health. It was originally coined by 19th-century German philosopher Ludwig Feuerbach, himself drawing on commentary by an earlier French gourmand Anthelme Brillat-Savarin.</p> <p>Increasingly, science is finding new connections between diet and our overall picture of health. You may have heard how our gut microbiome acts as a second brain, or that avoiding unprocessed foods can lead to all-cause mortality.</p> <p>But when it comes to many fad diets that promise quick weight loss or improved health, the science can sometimes be skimp. This can change over time as researchers test the influence of diet on general health, weight management and as a medical treatment.</p> <p>The <a href="https://cosmosmagazine.com/health/mediterranean-diet-heart-dementia/">Mediterranean diet</a> is probably closest to the mark as a lifestyle of choice, in terms of overall health, nutrition, and diet science. It emphasises <a href="https://cosmosmagazine.com/health/nutrition/plant-based-diets-could-prevent-type-2-diabetes/">fruit and vegetable</a> consumption, with some wholegrain breads and cereals, legumes, nuts, seeds and fish, with olive oil as a primary fat source.</p> <p>This diet is either explicitly endorsed by many health authorities around the world such as the <a href="https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/nutrition-basics/mediterranean-diet" target="_blank" rel="noreferrer noopener">American Heart Association</a>, the <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/handi/handi-interventions/nutrition/mediterranean-diet-for-reducing-cardiovascular-dis" target="_blank" rel="noreferrer noopener">Royal Australian College of General Practitioners</a> as a diet for lowering cardiovascular disease risk, or used as a basis for other recommendations. The World Health Organization also <a href="https://www.who.int/europe/news/item/07-05-2018-fostering-healthier-and-more-sustainable-diets-learning-from-the-mediterranean-and-new-nordic-experience" target="_blank" rel="noreferrer noopener">advises</a> on ways for the Mediterranean and similar New Nordic diets to be implemented as <a href="https://iris.who.int/bitstream/handle/10665/326264/9789289053013-eng.pdf?sequence=3" target="_blank" rel="noreferrer noopener">health policy</a>.</p> <p>But diet might be better considered about more than what goes in one’s mouth.</p> <p>Dr Evangeline Mantzioris, Program Director of the Nutrition and Food Sciences Degree at the University of South Australia, says a truer interpretation of the world extends beyond merely food and drink.</p> <p>“The word diet actually derives from the Greek word <em>diaita</em>, which means the way you choose to live your life,” Mantzioris told the <a href="https://cosmosmagazine.com/tag/debunks/" target="_blank" rel="noreferrer noopener"><em>Debunks</em> podcast.</a></p> <p>“So it’s not just about the food, it’s about the exercise, it’s about the social interaction, it’s about the rest. It’s about the sleep. It’s all of that.”</p> <p>The WHO’s 2019 Health Evidence Network Synthesis Report also acknowledges both social and sleep components of the lifestyle, noting shared eating practices, post-meal siestas and lengthy meal times all contribute to positive health effects.</p> <p>In terms of the nutritional component, Mantzioris notes that adherence to the diet requires not just an uptake of olive oil, but cutting down on less beneficial foods and an active lifestyle.</p> <p>“It’s not just the olive oil, it’s dropping down the meat, it’s mainly a plant food diet, it’s purposeful exercise,” she says.</p> <p>“I’m always a little bit nervous when people just talk about the diet and the food without considering the rest of it.</p> <p>“In the 60s, when the health benefits of the Mediterranean diet were seen […] they were out there harvesting, growing their food, preparing their food, doing all that sort of purposeful exercise in the outdoor environment, often in quite steep terrain. So that is just as important.</p> <p>“The Mediterranean diet continues to be shown to be quite healthy and beneficial in terms of improving chronic disease risk, even without weight loss.”</p> <p>Mantzioris says that the diet has also been shown to improve cognitive and mental health outcomes.</p> <p>Diet is the focus of the latest episode of <em>Debunks</em> from Cosmos and 9Podcasts, where we dive not simply into what makes a good diet, but the principles that dieticians and nutritionists look for when recommending one for a patient to consider.</p> <p><iframe title="Weight: Do diets actually work?" src="https://omny.fm/shows/debunks/weight-do-diets-actually-work/embed?style=Artwork" width="100%" height="180" frameborder="0"></iframe> <!-- Start of tracking content syndication.

What is the OMAD diet? Is one meal a day actually good for weight loss? And is it safe?

<p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>What do British Prime Minister <a href="https://www.sciencefocus.com/the-human-body/one-meal-a-day-diet-omad">Rishi Sunak</a> and singer <a href="https://theconversation.com/one-meal-a-day-diet-popular-with-celebrities-could-do-more-harm-than-good-heres-why-203086">Bruce Springsteen</a> have in common?</p> <p>They’re among an ever-growing group of public figures touting the benefits of eating just one meal a day.</p> <p>As a result, the one meal a day (OMAD) diet is the latest attention-grabbing weight loss trend. Advocates claim it leads to fast, long-term weight loss success and better health, including delaying the ageing process.</p> <p>Like most weight-loss programs, the OMAD diet makes big and bold promises. Here’s what you need to know about eating one meal a day and what it means for weight loss.</p> <h2>The OMAD diet explained</h2> <p>Essentially, the OMAD diet is a type of intermittent fasting, where you fast for 23 hours and consume all your daily calories in one meal eaten within one hour.</p> <p>The OMAD diet rules are presented as simple and easy to follow:</p> <ol> <li> <p>You can eat whatever you want, provided it fits on a standard dinner plate, with no calorie restrictions or nutritional guidelines to follow.</p> </li> <li> <p>You can drink calorie-free drinks throughout the day (water, black tea and coffee).</p> </li> <li> <p>You must follow a consistent meal schedule, eating your one meal around the same time each day.</p> </li> </ol> <p>Along with creating a calorie deficit, resulting in weight loss, advocates believe the OMAD diet’s extended fasting period <a href="https://www.frontiersin.org/articles/10.3389/fphys.2021.771944/full">leads to physiological changes</a> in the body that promote better health, including boosting your metabolism by triggering a process called ketosis, where your body burns stored fat for energy instead of glucose.</p> <h2>What does the evidence say?</h2> <p>Unfortunately, research into the OMAD diet is limited. Most studies have examined its impact on <a href="https://www.cell.com/cell-metabolism/pdf/S1550-4131(18)30512-6.pdf">animals</a>, and the <a href="https://pubmed.ncbi.nlm.nih.gov/35087416/">primary study</a> with humans involved 11 lean, young people following the OMAD diet for a mere 11 days.</p> <p>Claims about the OMAD diet typically rely on research into intermittent fasting, rather than on the OMAD diet itself. There is <a href="https://www.cfp.ca/content/66/2/117.short">evidence</a> backing the efficacy of intermittent fasting to achieve weight loss. However, <a href="https://www.nature.com/articles/s41574-022-00638-x">most studies</a> have focused on short-term results only, typically considering the results achieved across 12 weeks or less.</p> <p>One <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">longer-term study from 2022</a> randomly assigned 139 patients with obesity to either a calorie-restricted diet with time-restricted eating between 8am and 4pm daily, or to a diet with daily calorie restriction alone for 12 months.</p> <p>After 12 months, both groups had lost around the same weight and experienced similar changes in body fat, blood sugar, cholesterol and blood pressure. This indicates long-term weight loss achieved with intermittent fasting is not superior and on a par with that achieved by traditional dieting approaches (daily calorie restriction).</p> <h2>So what are the problems with the OMAD diet?</h2> <p><strong>1. It can cause nutritional deficiencies and health issues.</strong></p> <p>The OMAD diet’s lack of nutritional guidance on what to eat for that one meal a day raises many red flags.</p> <p>The meals we eat every day should include a source of protein balanced with wholegrain carbs, vegetables, fruits, protein and good fats to support <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7071223/">optimum health, disease prevention and weight management</a>.</p> <p>Not eating a balanced diet will result in nutritional deficiencies that can result in poor immune function, fatigue and a decrease in bone density, leading to osteoporosis.</p> <p>Fasting for 23 hours a day is also likely to lead to extreme feelings of hunger and uncontrollable cravings, which may mean you consistently eat foods that are not good for you when it’s time to eat.</p> <p><strong>2. It’s unlikely to be sustainable.</strong></p> <p>You might be able to stick with the OMAD diet initially, but it will wear thin over time.</p> <p>Extreme diets – especially ones prescribing extended periods of fasting – aren’t enjoyable, leading to feelings of deprivation and social isolation during meal times. It’s hard enough to refuse a piece of office birthday cake at the best of times, imagine how this would feel when you haven’t eaten for 23 hours!</p> <p>Restrictive eating can also lead to an unhealthy relationship with food, making it even harder to achieve and maintain a healthy weight.</p> <p><strong>3. Quick fixes don’t work.</strong></p> <p>Like other popular intermittent fasting methods, the OMAD diet appeals because it’s easy to digest, and the results appear fast.</p> <p>But the OMAD diet is just another fancy way of cutting calories to achieve a quick drop on the scales.</p> <p>As your weight falls, things will quickly go downhill when your <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4766925/">body activates its defence mechanisms</a> to defend your weight loss. In fact, it will regain weight – a response that stems from our hunter-gatherer ancestors’ need to survive periods of deprivation when food was scarce.</p> <h2>The bottom line</h2> <p>Despite the hype, the OMAD diet is unsustainable, and it doesn’t result in better weight-loss outcomes than its predecessors. Our old habits creep back in and we find ourselves fighting a cascade of physiological changes to ensure we regain the weight we lost.</p> <p>Successfully losing weight long-term comes down to:</p> <ul> <li> <p>losing weight in small manageable chunks you can sustain, specifically periods of weight loss, followed by periods of weight maintenance, and so on, until you achieve your goal weight</p> </li> <li> <p>making gradual changes to your lifestyle to ensure you form habits that last a lifetime.</p> </li> </ul> <p><em><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, Charles Perkins Centre Research Program Leader, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

The happiness diet: 7 foods to boost your mood

<p><strong>Mood boosting foods worth adding to your shopping trolley</strong></p> <p>For decades, our culture has focused on the connection between healthy eating and physiological wellness – most of all, related to weight. But out of a pandemic that made mental health a hot topic, you might also be gaining an awareness that the food you eat can seriously affect your mind.</p> <p>Research published in The British Medical Journal says diet plays a major role in how both our body and our brain are feeling. Poor nutrition can contribute to depression, anxiety, aggression (there’s a reason the word “hangry” exists!). But improving your diet, and knowing the right foods to eat, may help your mental health.</p> <p>Dietitian and certified intuitive eating counsellor Rachel Engelhart says certain foods can support your body’s processes that are responsible for positive moods and strong energy levels. Here’s Engelhart’s list of the greatest mood-boosting foods.</p> <p><strong>Fatty fish</strong></p> <p>Seafood like salmon, mackerel and canned tuna are rich in omega-3 fatty acids, which are ‘healthy fats’ with benefits throughout your body – from your heart to your eyes – and your brain.</p> <p>“Omega-3 fatty acids are anti-inflammatory and have the ability to cross into the brain, having a direct effect on mood-regulating molecules and neurotransmitters there,” says registered dietitian Kelsey Lorencz. Research has consistently linked low levels of omega-3s with mood disorders like depression and anxiety – and, according to a review published in Frontiers in Physiology, most of us don’t get enough omega-3 fats in our diet.</p> <p><strong>Yoghurt</strong></p> <p>According to Lorencz, “The bacteria in your gut can actually produce feel-good neurotransmitters like serotonin and dopamine.”</p> <p>Research has identified a particular bacterium that may have a strong impact on triggering these chemicals: a strain called Lactobacillus. One study published in the journal Nature found that feeding our gut with this good bacteria – found naturally in foods like yoghurt, kefir, and sauerkraut – doesn’t just keep the blues at bay, it can increase our resilience in the face of stress.</p> <p><strong>Bananas</strong></p> <p>Bananas aren’t just shaped like a smile – they’re a mood-boosting powerhouse. That’s in part because they’re also high in vitamin B6, one nutrient behind the production of the ‘happiness hormone’ serotonin. Bananas contain prebiotic fibre, which, along with that Lactobacillus, are essential for gut health that promotes a happy brain.</p> <p><strong>Cottage cheese</strong></p> <p>“The amino acid L-tyrosine is needed to make dopamine and norepinephrine, two neurotransmitters that affect our mood and can easily become depleted,” Lorencz says. She points to high sources like soy products, chicken, fish, nuts, seeds, avocados and bananas. But cottage cheese has a whopping amount of this amino acid, along with a few other mood-boosters in its arsenal. It’s high in protein, which is essential for our body to make and use its mood-promoting hormones, Engelhart says. (This protein is casein protein, which our body absorbs more slowly, sustaining energy levels, and may contribute to elevated moods, according to ongoing research.)</p> <p>Cottage cheese also contains selenium, a mineral that Nutrients research has suggested may be linked with lower rates of depression.</p> <p><strong>Nuts and seeds</strong></p> <p>Magnesium is a mineral that supports our body’s energy production – and not getting enough can lead to irritability, anxiety, sleeplessness and agitation, says Lorencz. Nuts like almonds, walnuts, cashews and seeds like pumpkin, chia and sesame are great sources of this vital nutrient, as well as tryptophan, an amino acid associated with good moods.</p> <p>Nuts and seeds can also be great vegetarian sources of those crucial omega-3 fatty acids.</p> <p><strong>Oysters</strong></p> <p>The ages-old wives’ tale about oysters as aphrodisiacs is still out for debate, but oysters can elevate one’s mood. They pack the highest zinc content of any food – a nutrient that’s linked with anxiety and depression when we’re deficient, says Lorencz – and contain tyrosine, an amino acid that helps our body produce the ‘feel good’ hormone dopamine.</p> <p>That’s great news for the shellfish-loving set. However, if you aren’t a fan of oysters, you can get this one-two mood-boosting punch from food like eggs, nuts and legumes.</p> <p><strong>Your favourite treat</strong></p> <p>“Having a varied diet is the best way to set your body up to produce the ‘feel good’ hormones that it needs,” Engelhart says, adding an important point: while this nutritious balance is important, so is treating yourself to food you enjoy. “So many of my clients are hard on themselves and rather judgmental around their food choices, and it negatively impacts their mood,” she says. “Sprinkling our day with a delicious coffee, a yummy dessert, or one of our favourite restaurant meals is also an important way to positively impact our mental health.”</p> <p>And if you want to be strategic about that treat, reach for some dark chocolate. Chocolate contains natural serotonin, and 2022 research found that dark chocolate has prebiotic effects in our gut, supporting stronger mental health.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/conditions/mental-health/the-happiness-diet-7-foods-to-boost-your-mood" target="_blank" rel="noopener">Reader's Digest</a>.</em></p>

9 signs you have inflammation in your body. Could an anti-inflammatory diet help?

<p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>There is a lot of health buzz around the term “inflammation” right now. From new scientific <a href="https://medicalxpress.com/news/2023-07-inflammation-discovery-aging-age-related-diseases.html">discoveries</a> to <a href="https://people.com/health/gwyneth-paltrow-addresses-backlash-anti-inflammatory-diet/">celebrities</a> and social media influencers, it seems like everyone is talking about this important bodily process and its potential impact on our health.</p> <p>“<a href="https://www.nature.com/articles/s41574-018-0059-4">Inflammaging</a>” is a specific term you may also have seen. It’s an age-related increase in persistent, low-grade inflammation in blood and tissue, which is a strong risk factor for many conditions and diseases.</p> <p>So, can an anti-inflammatory diet help reduce inflammation? Let’s take a look.</p> <h2>What is inflammation?</h2> <p>When our body becomes injured or encounters an infection, it activates defence mechanisms to protect itself. It does this by instructing our cells to fight off the invader. This fighting process <a href="https://www.nature.com/articles/s41591-019-0675-0#citeas">causes inflammation</a>, which often presents as swelling, redness and pain.</p> <p>In the short-term, inflammation is a sign your body is healing, whether from a grazed knee or a cold.</p> <p>If inflammation persists for a longer time it’s called “chronic”. That can indicate a <a href="https://www.nature.com/articles/s41467-018-05800-6">health problem</a> such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3638313/">arthritis</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6719998/#B2-ijms-20-03879">heart disease</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6523054/">diabetes</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3390758/">dementia</a> or other autoimmune disorders.</p> <p>The <a href="https://www.ncbi.nlm.nih.gov/books/NBK493173/">signs and symptoms</a> of chronic inflammation may be present from several months to years and include:</p> <ol> <li>persistent pain</li> <li>chronic fatigue or insomnia</li> <li>joint stiffness</li> <li>skin problems</li> <li>elevated blood markers (such as <a href="https://www.healthdirect.gov.au/c-reactive-protein-CRP-blood-test">C-reactive protein</a>)</li> <li>gastrointestinal issues (constipation, diarrhoea, acid reflux)</li> <li>depression, anxiety and mood disorders</li> <li>unintended weight gain or loss</li> <li>frequent colds or flu.</li> </ol> <h2>What role does diet play?</h2> <p>The relationship between food and inflammation is <a href="https://www.sciencedirect.com/science/article/pii/S0735109706013350">well recognised</a>. Overall, some food components may activate the immune system by producing pro-inflammatory cytokines (small proteins important in cell signaling) or reducing the production of anti-inflammatory cytokines.</p> <p>A “<a href="https://theconversation.com/clear-evidence-for-a-link-between-pro-inflammatory-diets-and-27-chronic-diseases-heres-how-you-can-eat-better-158451">pro-inflammatory diet</a>” may increase inflammation in the body over the long term. Such diets are usually low in fresh produce like fruits, vegetables and wholegrains, and high in commercially baked goods, fried foods, added sugars and red and processed meats.</p> <p>In contrast, an “<a href="https://academic.oup.com/ajcn/article/80/4/1029/4690355">anti-inflammatory</a>” diet is associated with less inflammation in the body. There is no single anti-inflammatory diet. Two well-recognised, evidence-backed examples are the Mediterranean diet and the Dietary Approaches to Stop Hypertension (DASH) diet.</p> <p>Anti-inflammatory diets typically include the following elements:</p> <p><strong>1. high in antioxidants.</strong> These compounds help the body fight free radicals or unstable atoms, that in high quantities are linked to illnesses such as cancer and heart disease. The best way to consume antioxidants is by eating lots of fruits and vegetables. Research shows frozen, dried and canned fruits and vegetables can be <a href="https://theconversation.com/frozen-and-tinned-foods-can-be-just-as-nutritious-as-fresh-produce-heres-how-201740">just as good as fresh</a></p> <p><strong>2. high in “healthy”, unsaturated fatty acids.</strong> Monounsaturated fats and omega-3-fatty acids are found in fish (sardines, mackerel, salmon and tuna), seeds, nuts, and plant-based oils (olive oil and flaxseed oil)</p> <p><strong>3. high in fibre and prebiotics.</strong> Carrots, cauliflower, broccoli and leafy greens are good sources of fibre.

A recent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8706441/">2021 systematic review</a> (where researchers carefully group and examine the available evidence on a topic) found eating an anti-inflammatory diet likely leads to significantly lower pain in people with rheumatoid arthritis when compared with other diets.</p> <p>However, the 12 studies included in the review had a high risk of bias – likely because people knew they were eating healthy foods – so the confidence in the evidence was low.</p> <p>Inflammation is strongly implicated in the development of neurodegenerative diseases like <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6486891/">Alzheimer’s disease and related dementia</a> and evidence suggests anti-inflammatory diets might help to protect the brain.</p> <p>A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5015034/">2016 review</a> showed an anti-inflammatory diet may be protective against cognitive impairment and dementia, but that further large randomised controlled trials are needed. A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8673721/">2021 study</a> followed 1,059 people for three years and observed their diet.

Vegan raw food influencer dies of suspected "starvation and exhaustion"

<p>Zhanna Samsonova, a well-known vegan raw food influencer with a significant following on social media, has tragically passed away in Malaysia reportedly due to starvation and exhaustion resulting from her 'extreme' tropical fruit diet.</p> <p>For a decade, Zhanna, also known as Zhanna D'Art, had maintained a raw plant-based diet, which mainly consisted of exotic fruits, sunflower seed sprouts, fruit smoothies, and juices. Additionally, she occasionally practiced 'dry fasting,' abstaining from food and water for extended periods.</p> <p>The 39-year-old influencer, who had not consumed water for over six years, replaced it solely with fruit and vegetable juices. On July 21, she succumbed to what her mother described as a cholera-like infection exacerbated by her highly restrictive eating habits.</p> <p>At the time of her passing, Zhanna was in Malaysia, continuing her travels across Asia, which had spanned 17 years. Her family faced bureaucratic challenges in repatriating her body back to Russia, making the mourning process even more difficult. At the time of writing, her official cause of death has not yet been determined.</p> <p>Zhanna's mother, Vera Samsonova, expressed her disapproval of her daughter's extreme diet and had attempted to persuade her to adopt a more balanced approach, but her efforts were in vain.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/p/CtLLqS1PecT/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/CtLLqS1PecT/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Raw food Creation by Zhanna D’art (@rawveganfoodchef)</a></p> </div> </blockquote> <p>Over time, the influencer transitioned from a vegan diet to a purely raw food diet, sharing what she believed were 'healthy' recipes on her Instagram profile. However, her social media presence started to reveal an increasingly emaciated appearance, raising concerns among her followers, friends, and family.</p> <p>Many of her loved ones warned her about the potential dangers of her extreme diet, but Zhanna remained steadfast in her convictions. Ultimately, her refusal to heed their advice led to a tragic outcome, with reports indicating that her raw food diet contributed significantly to her demise.</p> <p>In 2021, during a trip to Russia, Zhanna contracted COVID-19 and chose to handle it through an unorthodox method of dry fasting, lasting more than ten days. Despite initially claiming to have overcome the virus, her health may have been compromised, leading to further complications down the line.</p> <p>The passing of Zhanna Samsonova has sparked discussions about the importance of balanced and informed dietary choices. Her story serves as a cautionary tale, urging individuals to approach extreme diets with care and consideration for their overall well-being.</p> <p><em>Images: Instagram</em></p>

14 foods everyone over 50 should probably be eating

<p><strong>Beetroot </strong></p> <p>These sweet root veggies have a lot going for them. “The earthy vegetables can boost your energy, brain power, heart health, and more,” says Patricia Bannan, author of <em>Eat Right When Time is Tight</em>.</p> <p>“Beets are full of nitrates that can increase blood flow to the brain, which can help combat dementia.” The nitrates can also help keep blood pressure in check. “They’re converted to nitric oxide in the body and can help lower blood pressure by dilating blood vessels,” says Bannan.</p> <p><strong>Sunflower seeds</strong></p> <p>Who doesn’t want to keep their skin looking young? “A review study suggests that eating a combination of vitamin E and vitamin C can help protect the skin from UV damage,” says, dietitian Natalie Rizzo.</p> <p>“Sunflower seeds are an excellent source of vitamin E, and they pair nicely with a spinach salad. Spinach offers vitamin C.”</p> <p><strong>Pecans</strong></p> <p>They’re not just for pralines and pecan pie: “People over age 50 may worry about heart disease,” says dietitian Toby Amidor.</p> <p>“The unique mix of unsaturated fats, plant sterols, fibre, and flavonoids in pecans all add up to make pecans a heart-healthy nut. Research indicates that eating a serving of pecans each day may help reduce the risk of heart disease.”</p> <p><strong>Whey protein</strong></p> <p>“Since we know that the loss of muscle begins around age 30, it makes sense to think about foods that can help slow down the process of sarcopenia – age-related muscle loss,” says dietitian Ryan Whitcomb. While most nutrition experts will say it’s best to get protein from whole-food sources, obtaining enough is not always possible. You can supplement with whey, adding it to smoothies, yoghurt, pancake mix, and more.</p> <p>“Whey is a high-quality, complete protein,” says Whitcomb. “Another great thing about whey is that it is rich in cysteine, which leads to higher levels of glutathione in the body. Glutathione is one of the most important, if not the most important antioxidant in the body. Glutathione can help prevent the damage that free radicals may cause.”</p> <p><strong>Dark leafy greens </strong></p> <p>“These vegetables, such as collard greens and kale, are an excellent source of calcium,” says sports dietitian Angie Asche.</p> <p>“As you age, calcium needs are increased. One cup of cooked collard greens provides almost 30 per cent of the daily value for calcium, along with a number of other important nutrients such as vitamin K, vitamin A, vitamin C, potassium, and fibre.”</p> <p><strong>Beans</strong></p> <p>“As we get older, our risk of developing chronic diseases such as hyperlipidemia, high-cholesterol, and type 2 diabetes increases,” says nutritionist Emily Kyle. “Consuming a fibre-rich, plant-based diet that includes beans and legumes can help reduce the incidence of these diseases, while also providing an aging body with many important nutrients such as calcium, iron, and potassium.”</p> <p>Add chickpeas to a rice bowl or white beans to a pizza. “You don’t need to consume an entirely plant-based diet to reap the benefits of beans, just add them to the meals you are already cooking to begin to enjoy their nutritious benefits immediately,” notes Kyle.</p> <p><strong>Quinoa</strong></p> <p>Here’s another way to up your protein intake. “You can’t go wrong with this plant-based protein source,” says Dana Angelo White, author of the <em>Healthy Instant Pot Cookbook</em>. Quinoa is a complete protein, offering all nine essential amino acids.</p> <p>“It’s a higher protein substitute for brown rice in stir-fries, salads, and even burritos,” says Angelo White. You can also use quinoa as a base for a hearty salad.</p> <p><strong>Tomatoes</strong></p> <p>Here’s a food that you may already love – but did you know it can help prevent wrinkles? Because tomatoes boast the antioxidant lycopene, they may help protect skin from damage that may occur from sun exposure.</p> <p>Your body best absorbs the lycopene from cooked tomatoes, so try combining tomato sauce with pasta or spaghetti squash.</p> <p><strong>Mushrooms</strong></p> <p>“After age 50, it’s important for women to eat foods that counteract symptoms of menopause, like brittle bones and low bone density,” says Rizzo. “During this stage of life, it’s crucial to increase your intake of bone-boosting calcium and vitamin D."</p> <p>"Mushrooms are one of the few food sources of vitamin D, and research suggests using mushrooms as a substitute for beef may help reduce calories in your diet.” Make sure to look for mushrooms grown in sunlight or under UV light to get the biggest helping of vitamin D.</p> <p><strong>Prunes</strong></p> <p>Want to keep your bones strong as you get older? “Research suggests that eating five to six prunes each day may help to prevent bone loss,” says nutritionist Erin Palinski-Wade. “And since bone loss can accelerate after age 50, adding a food like prunes can be key for this population.”</p> <p>As a no-sugar-added dried fruit, prunes are a great way to promote digestive health with three grams of fibre per serving, she adds.</p> <p>Eggs</p> <p><strong>Here’s</strong> help for your noggin: Eating eggs can help boost brain health. “There is new research that shows that eating eggs has been associated with improved cognitive performance in adults,” says nutritionist Angelo White.</p> <p>“In fact, lutein that’s found in eggs has been shown to play a role in cognition in older adults.” You can add eggs to anything from fried rice to sandwiches.</p> <p><strong>Chia seeds</strong></p> <p>These crunchy seeds provide crucial nutrients for healthy aging. “Chia seeds are a plant-based source of two nutrients, calcium, and omega-3 fatty acids, that become even more significant to our health as we get older,” says Kyle.</p> <p>“The calcium can help support bone health, and the omega-3s can help support brain health.” Add chia seeds to salads for a bit of crunch or incorporate them into a chia seed pudding.</p> <p><strong>Grapes</strong></p> <p>“The whole grape, which contains more than 1600 natural plant compounds – including antioxidants and other polyphenols – offers a range of intriguing health benefits when included in our daily diet,” says Bannan, a nutritionist.</p> <p>“These include benefits to the heart, eyes, brain, and joints. A ¾ cup of grapes contains just 90 calories, and grapes of all colours are a natural source of antioxidants and other polyphenols.”</p> <p><strong>Greek yoghurt</strong></p> <p>Hello, nutritional powerhouse: “Besides being tasty, Greek yoghurt provides about 40 per cent less sodium and sugar compared to traditional yoghurt – with twice the protein,” says Amidor.</p> <p>“Greek yoghurt also provides live and active cultures, which act as probiotics for digestive health. Research shows that Greek yoghurt may be useful in lowering the risk of heart disease and type 2 diabetes.”</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/diet/14-foods-everyone-over-50-should-probably-be-eating?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Does artificial sweetener aspartame really cause cancer? What the WHO listing means for your diet soft drink habit

<p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>The International Agency for Research on Cancer (IARC), which is the specialised cancer agency of the World Health Organization, has declared aspartame may be a <a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">possible carcinogenic hazard to humans</a>.</p> <p>Another branch of the WHO, the Joint WHO and Food and Agriculture Organization’s Expert Committee on Food Additives has assessed the risk and developed recommendations on how much aspartame is safe to consume. They have recommended the acceptable daily intake be 0 to 40mg per kilo of body weight, as we currently have <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">in Australia</a>.</p> <p>A hazard is different to a risk. The hazard rating means it’s an agent that is capable of causing cancer; a risk measures the likelihood it could cause cancer.</p> <p>So what does this hazard assessment mean for you?</p> <h2>Firstly, what is aspartame?</h2> <p><a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">Aspartame is an artificial sweetener</a> that is 200 times sweeter than sugar, but without any kilojoules.</p> <p>It’s used in a <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame/Pages/default.aspx">variety of products</a> including carbonated drinks such as Coke Zero, Diet Coke, Pepsi Max and some home brand offerings. You can identify aspartame in drinks and foods by looking for additive number 951.</p> <p>Food products such as yogurt and confectionery may also contain aspartame, but it’s not stable at warm temperatures and thus not used in baked goods.</p> <p>Commercial names of aspartame include Equal, Nutrasweet, Canderel and Sugar Twin. In Australia the acceptable daily intake is 40mg per kilo of body weight per day, which is about 60 sachets.</p> <p><a href="https://www.fda.gov/food/food-additives-petitions/aspartame-and-other-sweeteners-food#:%7E:text=How%20many%20packets%20can%20a,based%20on%20its%20sweetness%20intensity%3F&amp;text=Notes%20About%20the%20Chart%3A,50%20mg%2Fkg%20bw%2Fd">In America</a> the acceptable daily intake has been set at 75 sachets.</p> <h2>What evidence have they used to come to this conclusion?</h2> <p><a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">IARC looked closely</a> at the <a href="https://cdn.who.int/media/docs/default-source/nutrition-and-food-safety/july-13-final-summary-of-findings-aspartame.pdf?sfvrsn=a531e2c1_5&amp;download=true">evidence base</a> from around the world – using data from observational studies, experimental studies and animal studies.</p> <p>They found there was some limited evidence in human studies linking aspartame and cancer (specifically liver cancer) and limited evidence from animal studies as well.</p> <p>They also considered the biological mechanism studies which showed how cancer may develop from the consumption of aspartame. Usually these are lab-based studies which show exactly how exposure to the agent may lead to a cancer. In this case they found there was limited evidence for how aspartame might cause cancer.</p> <p>There were only three human studies that looked at cancer and aspartame intake. These large observational studies used the intake of soft drinks as an indicator of aspartame intake.</p> <p>All three found a positive association between artificially sweetened beverages and liver cancer in either all of the population they were studying or sub-groups within them. But these studies could not rule out other factors that may have been responsible for the findings.</p> <p>A study <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6284800/">conducted in Europe</a> followed 475,000 people for 11 years and found that each additional serve of diet soft drink consumed per week was linked to a 6% increased risk of liver cancer. However the scientists did conclude that due to the rarity of liver cancer they still had small numbers of people in the study.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/35728406/">In a study from the US</a>, increased risk of liver cancer was seen in people with diabetes who drank more than two or more cans of a diet soda a week.</p> <p>The <a href="https://aacrjournals.org/cebp/article/31/10/1907/709398/Sugar-and-Artificially-Sweetened-Beverages-and">third study</a>, also from the US, found an increase in liver cancer risk in men who never smoked and drank two or more artificially sweetened drinks a day.</p> <p>From this they have decided to declare aspartame as a Group 2b “possible carcinogen”. But they have also said more and better research is needed to further understand the relationship between aspartame and cancer.</p> <p>IARC has four categories (groupings) available for potential substances (or as they are referred to by IARC, “agents”) that may cause cancer.</p> <h2>What does each grouping mean?</h2> <p><strong>Group 1 Carcinogenic to humans:</strong> an agent in this group is carcinogenic, which means there is convincing evidence from human studies and we know precisely <em>how</em> it causes cancer. There are 126 agents in this group, including tobacco smoking, alcohol, processed meat, radiation and ionising radiation.</p> <p><strong>Group 2a Probably carcinogenic to humans:</strong> there are positive associations between the agent and cancer in humans, but there may still be other explanations for the association which were not fully examined in the studies. There are 95 agents in this group, including red meat, DDT insecticide and night shift work.</p> <p><strong>Group 2b Possibly carcinogenic in humans:</strong> this means limited evidence of causing cancer in humans, but sufficient evidence from animal studies, or the mechanism of how the agent may be carcinogenic is well understood. This basically means the current evidence indicates an agent may possibly be carcinogenic, but more scientific evidence from better conducted studies is needed. There are now <a href="https://monographs.iarc.who.int/agents-classified-by-the-iarc/">323</a> agents in this group, including aloe vera (whole leaf extract), ginkgo biloba and lead.</p> <p><strong>Group 3 Not classifiable as a carcinogen:</strong> there’s not enough evidence from humans or animals, and there is limited mechanistic evidence of how it may be a carcinogen. There are 500 agents in this group.</p> <h2>So do I have to give up my diet soft drink habit?</h2> <p>For a 70kg person you would need to consume about 14 cans (over 5 litres) of soft drink sweetened with aspartame a day to reach the acceptable daily intake.</p> <p>But we need to remember there may also be aspartame added in other foods consumed. So this is an unrealistic amount to consume, but not impossible.</p> <p>We also need to consider all the evidence on aspartame together. The foods we typically see aspartame in are processed or ultra-processed, which have recently also been <a href="https://theconversation.com/ultra-processed-foods-are-trashing-our-health-and-the-planet-180115">shown to be detrimental to health</a>.</p> <p>And artificial sweeteners (including aspartame) <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2892765/#!po=59.3750">can make people crave more sugar</a>, making them want to eat more food, potentially causing them to gain more weight.</p> <p>All together, this indicates we should be more careful about the amount of artificial sweeteners we consume, since they <a href="https://theconversation.com/the-who-says-we-shouldnt-bother-with-artificial-sweeteners-for-weight-loss-or-health-is-sugar-better-205827">do not provide any health benefits</a>, and have possible adverse effects.</p> <p>But overall, from this evidence, drinking the occasional or even daily can of a diet drink is safe and probably not a cancer risk.</p> <hr /> <p><em>Correction: this article originally stated each serve of soft drink in a study was linked to a 6% increased risk of liver cancer, however it was each additional serve per week.

<p><em><a href="https://theconversation.com/profiles/adam-collins-1179004">Adam Collins</a>, <a href="https://theconversation.com/institutions/university-of-surrey-1201">University of Surrey</a></em></p> <p>When you go on a diet, you don’t just lose fat – you lose muscle too. This can have many repercussions – not only on your fitness and strength, but on your metabolism.</p> <p>To lose weight (body fat), you need to be in a calorie deficit. This means consuming fewer calories than your body uses, or exercising to burn more calories than you consume.</p> <p>During the first few days in a calorie deficit, the body uses up its small reservoir of <a href="https://pubmed.ncbi.nlm.nih.gov/1615908/">glycogen stores</a> for energy. Glycogen is a string of glucose (sugar) that comes from the carbohydrates you eat. Since carbs are the body’s main energy source, this is why any glucose the body doesn’t immediately use is stored to use for energy later.</p> <p>But as carbohydrate molecules bind with water, this means that when the body stores glycogen, it also stores water in the muscles. As these glycogen stores are used up, the body also releases a significant amount of water. This is often called “water weight”, and explains why some may feel they lose considerable weight early in their diet.</p> <p>Given you only have days’ worth of glycogen stores, this is why the body uses fat to store extra calories for when you need it. Once the glycogen stores are used up, the body shifts to metabolising fat to get the energy it needs to function.</p> <p>But not all tissues can use fat for energy – such as the brain. This is why the body needs to metabolise your muscles when you’re in a calorie deficit.</p> <p>Protein (from the food you eat) is stored in your muscles. The body can convert this stored protein into glucose for energy. But this means you subsequently lose the muscle tissue itself when that happens. This has significant consequences – including <a href="https://pubmed.ncbi.nlm.nih.gov/35103583/">slowing the metabolism</a>, which may ultimately drive weight regain after losing weight.</p> <h2>Muscle loss</h2> <p>Many factors can affect how much muscle you lose while in a calorie deficit.</p> <p>While it was once thought that the more fat you had, the <a href="https://pubmed.ncbi.nlm.nih.gov/10673906/">less muscle you lost</a> in a calorie deficit, this has since been disproved – with both <a href="https://pubmed.ncbi.nlm.nih.gov/3066619/">lean</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/17367567/">obese people</a> losing significant rates of muscle when dieting.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/29957829/">Ethnicity</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/32734691/">genetics</a> may, however, play a role – with studies showing black people tend to lose more muscle mass in a calorie deficit than white people do. Some research also suggests that genetic variants may make some people more susceptible to <a href="https://pubmed.ncbi.nlm.nih.gov/32734691/">certain dietary changes</a>, which may determine how much muscle mass they end up losing.</p> <p>Muscle loss will also happen regardless of whether you lose weight <a href="https://pubmed.ncbi.nlm.nih.gov/30925026/">gradually or quickly</a>. A better determinant of how much muscle you’ll lose depends on <a href="https://pubmed.ncbi.nlm.nih.gov/30925026/">how much weight you end up losing</a>. If a person loses 10% of their body weight, typically around 20% of this is fat-free mass (the proportion of body mass that isn’t fat – such as muscle). This can equate to several kilograms of muscle.</p> <p>Many people also think that what you eat while losing weight may determine how much muscle you lose, with it commonly believed that if you eat plenty of protein you’re less likely to lose muscle mass. This is <a href="https://pubmed.ncbi.nlm.nih.gov/19246357/">debatable</a>, with research showing people lose as much muscle on high-protein weight loss diets as people who followed other types of diets.</p> <p>Low-carb diets have also been claimed to promote more fat loss. But studies comparing <a href="https://pubmed.ncbi.nlm.nih.gov/22258266/">different types of diets</a> have found that low-fat high-carb diets seem to offer <a href="https://pubmed.ncbi.nlm.nih.gov/28193517/">the same, if not better, fat loss</a> than low-carb, high-fat diets – with no differences in muscle loss.</p> <h2>Protein and exercise</h2> <p>Given all that has been said, the only way to prevent muscle loss somewhat while losing weight is to combine exercise (particularly <a href="https://pubmed.ncbi.nlm.nih.gov/18356845/">resistance exercise</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/28507015/">endurance exercise</a>) with a diet higher in protein. This is because exercise stimulates muscle growth – but this process can only happen if you have an adequate supply of protein.</p> <p>It’s suggested adults normally aim to consume <a href="https://pubmed.ncbi.nlm.nih.gov/34371981/">0.8g of protein per kilogram of body weight</a> per day to maintain muscle mass. But given the extra demand exercise places on the muscles, a person will probably need to consume 1.2-1.5g of protein per kilogram of body weight to preserve muscle during weight loss. People who exercise a lot may need to increase that to more than <a href="https://pubmed.ncbi.nlm.nih.gov/28642676/">2g per kilogram of body weight</a> when losing weight. <a href="https://pubmed.ncbi.nlm.nih.gov/22221216/">Older people</a> may also need to consume more protein than average.</p> <p>Just be wary of consuming too much protein (more than 2.5g per kilogram of body weight) as eating more than your body uses could have an <a href="https://pubmed.ncbi.nlm.nih.gov/28507015/">adverse effect</a> on your metabolism by potentially making the body less able to draw upon glucose for energy. It may also put greater pressure on the kidneys and liver – which could lead to serious <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7460905/#:%7E:text=High%20dietary%20protein%20intake%20can,a%20role%20in%20kidney%20health.">health issues</a>, such as liver and kidney damage.</p> <p>Even if you prevent muscle loss when losing weight, other metabolic changes still happen that promote weight regain – such as changes in your metabolic rate (the minimum amount of calories your body needs to survive) and <a href="https://pubmed.ncbi.nlm.nih.gov/21677272/">increases in appetite and hunger</a>. This is why, when trying to lose weight, the most important thing to consider is how sustainable your diet and lifestyle changes are. The easier these are to maintain, the better chances you have of keeping the weight off.<!-- Below is The Conversation's page counter tag.

11 foods successful keto dieters never eat

<h2>Smart keto foods</h2> <h2>A ketogenic (or ‘keto’) diet is a low-carbohydrate, high-fat diet, which means the body burns fat as its main source of fuel and breaks it down into ‘ketone bodies’ (or ‘ketones’) in a process called ketosis, leading to rapid weight loss.</h2> <p>A lot of tasty foods are OK for keto eaters – avocado, fish, and butter, for example. Some other delicious foods might be keto friendly, but people who’ve had weight-loss success on the keto diet think you should avoid them anyway. Here’s why.</p> <h2>Zero-carbohydrate foods</h2> <p>People on the ketogenic (keto) diet are fastidious carbohydrate counters. After all, most keto eaters aim to eat around 20 net – or total – carbs in a day. With a number that low, every single bite counts. Low- and no-carb foods may be particularly alluring for that reason, but health coach, Jessica Rosen, says you should be wary. “Not all zero-carbohydrate foods are smart choices for a keto dieter,” Rosen says. “Artificial sweeteners may not have any carbs or calories, but they can negatively impact the healthy bacteria in your gut. That can lead to fat storage and digestive issues,” she says. “Degrading one’s gut bacteria can be particularly detrimental if you’re eating a diet high in difficult-to-digest proteins and fats.”</p> <h2>Processed meats</h2> <p>If you assume the keto diet consists of eating limitless breakfast meats, your idea of healthy keto eating may need some fine-tuning. “Processed meats such as sausage, hot dogs, bacon, and tinned meats should be avoided as much as possible as they are loaded with carcinogens,” Rosen says.</p> <p>“These processed meats have zero carbs so people think they are fine to eat on keto,” says keto expert and global integrative health coach Krissa Long. “But these ultra-processed meats typically contain nitrites. When nitrites are exposed to high heat in the presence of protein – that is, the meats they have been added to – they can turn into compounds called nitrosamines, which are known carcinogens.” Rosen advises you instead pick “organic, grass-fed meat whenever possible.” It will help make sure you get all the benefits of the keto diet.</p> <h2>Refined oils</h2> <p>The average ketogenic dieter aims to get at least three-quarters of their macronutrients from fats. That includes sources like avocado, dairy, fish, nuts and seeds. Many people rely on cooking oils for daily fat intake, too. These include canola oil, grapeseed oil, soybean oil, corn oil, sunflower oil, safflower oil and peanut oil. However, Long says these may not be the healthiest choice. “These refined cooking oils are made by highly intensive mechanical and chemical processes to extract the oil from the seeds,” she says. “This process removes the natural nutrients from the seeds and creates a final product which oxidises easily. The oxidation factor makes these oils more likely to break down into cancer-causing free radicals within the body, especially when heated.” Long says the consumption of these refined oils “has been linked to widespread inflammation within the body, elevated blood triglycerides, and impaired insulin response.”</p> <h2>Sugar-free sweets</h2> <p>Here again, sugar-free sweets may seem like a dream come true, especially when a craving for lollies, brownies or ice cream hits, but just because they’re low-carb or keto-friendly doesn’t make them right for you.</p> <p>“Many people lean on foods that are low- or zero-carb and will eat anything as long as it fits the keto macros, but I always stress food quality first,” says New York Times bestselling author and certified nutrition consultant Diane Sanfilippo.</p> <h2>Fast food </h2> <p>Social media is loaded with accounts dedicated to keto eating on the go. Many of these include fast food hacks for people who don’t have time – or don’t like – to cook. While popular, Sanfilippo says this is something you should avoid with your own keto eating plans. “I don’t eat fast food despite many keto options like bunless burgers,” Sanfilippo says. “I prefer to stop into a grocery store on a road trip if I’m in a pinch and need a bite without time or a restaurant in sight. I scope out easy, ready-to-eat options like roasted deli turkey, prosciutto, quality goat cheese, and some veggies.”</p> <h2>Protein products</h2> <p>While keto eating may focus on fat consumption, protein is also important in your daily diet. Although you may think you need to eat protein-enhanced products in order to reach your daily goal, you could be setting yourself back. “Many keto eaters start eating lots of protein products as these are very trendy right now,” says functional medicine practitioner, Dr  Philip Oubre, who frequently recommends the ketogenic diet. A true keto plan is 60 to 90 per cent fat depending on preference, Dr Oubre says. The remaining percentages fall to protein (10 to 30 per cent) and carbohydrates (less than five per cent).</p> <h2>Red wine</h2> <p>Most beers and cocktails are entirely off limits because the carb counts are too high, but some clear liquors and wines frequently get the thumbs up among keto dieters. However, if you’re really trying to stick to a clean keto lifestyle, nutritionist and dietitian, Dr Keith Kantor, says you should avoid alcohol and wine altogether. “Red wine appears on a few of the keto-approved food lists, but in order to experience the benefits of being in ketosis, you should avoid red wine,” says Dr Kantor says. “Alcohol can hinder the body’s ability to effectively burn fat as fuel.”</p> <h2>Dark chocolate</h2> <p>When you want to slip in a little something sweet, you may be tempted to reach for ultra-dark chocolate, a food that’s frequently touted as keto-friendly. But be careful what you nibble, Dr Kantor says. “Dark chocolate should also be avoided or only consumed as a special treat, not regularly,” he says. “Even the highest per cent of dark chocolate has some sugar in it, and if your body has a difficult time remaining in ketosis, it will throw off your metabolism, excluding you from the health benefits of being in ketosis.”</p> <h2>Fat bombs</h2> <p>These popular snacks loaded with butter, peanut butter, cocoa, and other ingredients come in both savoury and sweet forms. They’re touted as the surest way to reach your daily fat total. But are they necessary? No, says Stephanie Laska, author of Dirty, Lazy Keto.  In fact, she avoids them entirely. “First of all, they’re gross,” Laska says. “Who wants to eat just fat? Rather, I feel it is beneficial to enjoy fats with regular food.” Laska says butter on Brussels sprouts is a much better investment in her health. “I also want to burn fat from my booty, not from my coffee loaded with heavy whipped cream,” Laska says.</p> <h2>Thickened cream</h2> <p>Most milk and milk products like yoghurt are off limits for keto eaters because the natural sugars in dairy can quickly top your carb counts. Thickened cream, however, isn’t a high-carb dairy food, so it’s popular in keto dishes, drinks and more. That doesn’t mean it should be in yours, says dietitian, Emmie Satrazemis. “There is little to no nutrition in this food,” Satrazemis says. Plus, people who are dairy sensitive may find that it doesn’t agree with their stomach, adds Satrazemis adds.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/11-foods-successful-keto-dieters-never-eat" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

5 healthy foods that can make you hungrier

<p>While often considered healthy food options, some diet choices could be leading you to overconsume later on. Take a look at some of the top offenders below.</p> <p><strong>1. Wholegrain bread</strong> – It may keep you fuller longer than its white counterpart, but bread is still a carb, and so elevates your blood sugar. Raised insulin levels can, on the more serious end, lead to diabetes, but at the least, the subsequent sugar crash can leave you reaching for more carbs and sugar.</p> <p><strong>2. Yoghurt</strong> – Many yoghurts contain added sugars, the effects of which are mentioned above, and due to its runny texture, won’t leave your hunger feeling satisfied. Add nuts and honey to unflavoured Greek yoghurt instead of consuming the non-fat sugary kind. Your satisfaction levels will thank you for it.</p> <p><strong>3. Green smoothies</strong> – Like yoghurt, despite being healthy, fast-consumed liquid smoothies don’t signal to our bodies that our hunger is satisfied so well as solid foods do, and could lead to more snacking later as a result.</p> <p><strong>4. Red wine</strong> – We’ve all heard of the benefits of having one glass of anti-oxidant rich red wine per day, but as wine lowers inhibitions, it could lead to over-eating at dinner.</p> <p><strong>5. Artificial sweeteners</strong> – You might think, with less calories than real sugar, that artificial sweeteners are a better choice, but as they trick your brain into thinking they are about to receive sugar-derived energy, they can actually lead to sugar or carb cravings later.</p> <p><em>Image credit: Shutterstock</em></p>

Aussies guilty of neglecting at-home pet care

<p dir="ltr">New research has revealed that Australian pet owners are overlooking home health checks for their furry friends.</p> <p dir="ltr">A report released by PetSure recording data from 2022 for 2023 showed that just one in 10 pet owners provided at-home health checks for their pets, including things such as brushing their pet’s teeth or checking for fleas and ticks. </p> <p dir="ltr">However, even with the cost of living crisis, the report found 82 per cent of pet owners spoil their pet’s each month. </p> <p dir="ltr">"With pet ownership across Australia at a record high, companion animals continue to play a central role in our lives, but there is still a knowledge gap when it comes to pet health and the role pet insurance can play in helping you prepare for the unexpected," CEO of PetSure Alex Thomas said.</p> <p dir="ltr">The data analysed in the report shows the top five health conditions for dogs and cats. </p> <p dir="ltr">The top five dog diseases in 2022 included skin allergies, arthritis, diarrhoea, ear infections, and gastritis.</p> <p dir="ltr">For cats, it was vomiting, gastrointestinal tract diseases, dental disease, diarrhoea and urinary tract disease.</p> <p dir="ltr">"Like many pet owners, vets are animal lovers and they want the best for your fur baby, but pet parents need to do their due diligence. While pampering can provide enrichment for pets, it's simple things like regularly brushing your dog's teeth or checking for fleas and ticks that pet parents should prioritise," vet Dr Betty Chan said.</p> <p dir="ltr">"Being proactive with a regular at-home health routine could help detect and address issues early on, resulting in better pet healthcare outcomes. In some cases, this could mean a health condition is less complex and costly to treat – leading to a more positive experience for pets, their owners and vets,” she continued.</p> <p dir="ltr">Vets Dr Betty Chan and Dr Kylie have provided a few tips for those neglecting at-home pet checks. </p> <p dir="ltr">With skin allergies in dogs, which were the number one health condition for dogs in 2023, the vets recommend monitoring closely and taking them for regular checkups.</p> <p dir="ltr">They also said to stay up-to-date with flea treatments, which will help to avoid allergies triggered by itchy skin. </p> <p dir="ltr">While the number one condition for cats in 2022 was vomiting, this may indicate there is an issue with their gastrointestinal tract.</p> <p dir="ltr">The vets recommend feeding them a high-quality vet-recommended diet, avoiding sudden changes in their diet and increasing their water intake if they experience constipation. </p> <p> </p> <p dir="ltr"><em>Image credit: Shutterstock</em></p>

Naturally combat the onset of diabetes

<p dir="ltr">Pre-diabetes is the period before diabetes is officially diagnosed. Progressing from pre-diabetes to diabetes is not imminent. There are plenty of ways you can get on top of it to reduce the risk of diabetes. </p> <p dir="ltr" role="presentation"><strong>1. Cut out sugar and refined carbohydrates </strong></p> <p dir="ltr">Eating foods high in refined carbs and sugar increases blood sugar and insulin levels, which could lead to diabetes over time. Examples of these foods are white bread, potatoes and various breakfast cereals. Limit sugar and choose complex carbs like veggies, oatmeal and whole grains.</p> <p dir="ltr"><strong>2. Quit smoking</strong></p> <p dir="ltr">If you’re a current smoker, cut it out! Smoking can contribute to insulin resistance which can lead to type 2 diabetes. Quitting smoking has been shown to reduce the risk of developing type 2 diabetes over time.</p> <p dir="ltr"><strong>3. Portion control</strong></p> <p dir="ltr">Avoid large portions as they can contribute to the increase of insulin and blood sugar levels. Eating too much at one time can lead to higher blood sugar and insulin levels in pre-diabetics.</p> <p dir="ltr"><strong>4. Exercise</strong></p> <p dir="ltr">Aim for at least 30 minutes of exercise a day. You don’t have to strain yourself, you can take a walk, go swimming or dance around the house, but make sure you stay on top of it and practise these activities at least five days a week. </p> <p dir="ltr"><strong>5. Drink more water</strong></p> <p dir="ltr">Drinking water over other beverages may help control blood sugar and insulin levels. Drinking primarily water will stop you from over consuming beverages that are high in sugar and preservatives, in turn reducing the risk of diabetes.</p> <p dir="ltr"><strong>6. Eat more fibre</strong></p> <p dir="ltr">Getting an adequate amount of fibre is beneficial for gut health and weight management. Having a good source of fibre at each meal can help prevent spikes in blood sugar and insulin levels. </p> <p dir="ltr"><em>Image credit: Shutterstock</em></p>

Cooking mistakes that are making your food unhealthy

<p><strong>Boiling your veggies</strong></p> <p>A review published in the <em>International Journal of Gastronomy and Food Science</em> in 2016 showed that boiling vegetables resulted in a high loss of vitamin C and folate. One study found that broccoli, for example, lost about 33 per cent of its vitamin C. “Water-soluble vitamins leach out,” says Nishta Saxena, a registered dietitian. “If you’re not using the fluids in something like a soup, you’re missing out on nutrients.”</p> <p><strong>Rinsing raw chicken</strong></p> <p>While your favourite old cookbooks likely tell you to rinse a chicken before roasting, this outdated advice is a safety hazard. Running poultry under the tap may remove some of the bacteria (including salmonella and campylobacter, which can cause diarrhoea, vomiting and fever), but it’s also likely to transfer it around your kitchen –as far as nearly one metre from the sink, according to research from Drexel University in Philadelphia. “Droplets can spread from your hands to counter­tops and even onto the floor, which can be a concern, especially if you have small children,” says Saxena. To stay safe, skip the rinse and wash your hands thoroughly after you’re finished prepping your bird.</p> <p><strong>Removing skins from produce</strong></p> <p>Peeling your produce rids your food of an important layer of nutrients. “Significant amounts of vitamins, minerals and fibre are found in the skins,” says Liz Powell, a registered dietitian. Researchers at the University of Maine estimate that the skins of potatoes, for example, contain 10 to 12 times more antioxidants than the flesh. Peeling fruits and vegetables also strips away a dose of insoluble fibre, which is crucial for digestion and bowel function. Concern about herbicide or pesticide residue isn’t a good enough reason to forego the peelings, says Powell. Washing your fresh produce will remove some pesticide residues from the surface, she says. You can also opt for organic varieties of heavily sprayed produce, such as peaches.</p> <p><strong>Blending everything</strong></p> <p>A smoothie is a smart way to sneak in some greens (and down your breakfast in a hurry), but liquid meals tend to be unbalanced. They’re often lacking in protein, healthy fat and complex carbohydrates. These components work together to keep us feeling full and satisfied, Powell says. “Without them, it’s not really a balanced meal.” Powell recommends adding a scoop of yoghurt or protein powder and part of an avocado or a spoonful of hemp hearts for protein and fat. To sneak in a complex carb, you can add some oats to the blender or have a piece of wholegrain toast on the side, she says.</p> <p><strong>Overdressing salads</strong></p> <p>“Salads have this health halo – we think we can add anything to them and they’ll still be a nutritious choice, but it’s just not true,” says Saxena. “If you’re topping your bowl with dried cranberries, candied pecans and a sweet goat cheese, you’ve easily added 30 grams of sugar to your so-called healthy lunch.” Chopped, raw nuts and seeds are better options to beef up the flavour profile of your greens. Oil-based dressings also tend to be more nutritious than their creamy counterparts.</p> <p><em>Image credit: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/home-tips/cooking-mistakes-that-are-making-your-food-unhealthy" target="_blank" rel="noopener">Reader's Digest</a></em>. </p>
