Eating some chocolate really might be good for you – here’s what the research says

<p><em><a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a></em></p> <p>Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year.</p> <p>It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you?</p> <p>Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state.</p> <p>In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs.</p> <p>Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue.</p> <p>One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals.</p> <p>These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals.</p> <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal.</p> <p>Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks.</p> <h2>Health benefits of cocoa</h2> <p>There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido.</p> <p>These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes.</p> <p>Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels.</p> <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart.</p> <p>Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>.</p> <h2>Chocolate toxicity</h2> <p>As much as chocolate might be considered a medicine for some, it can be a poison for others.</p> <p>It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures.</p> <p>The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms.</p> <p>Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>.</p> <p>Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones.</p> <p>So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits.</p> <p>A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high.</p> <p>But whatever chocolate you go for, please don’t share it with the dog.<!-- Below is The Conversation's page counter tag.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<p><em><a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a></em></p> <p>Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season.</p> <p>Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates.</p> <p>There are several health benefits and potential problems that come in these sweet chocolatey packages.</p> <h2>The good news</h2> <p>Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>.</p> <p>These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation.</p> <p>However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product.</p> <p>In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates.</p> <h2>But also some bad news</h2> <p>Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories).</p> <p>Also, there may be some side effects that come with ingesting chocolate.</p> <p>Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate.</p> <p>But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea.</p> <h2>What else is in your chocolate?</h2> <p>Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose).</p> <p>People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms.</p> <p>It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate.</p> <p>Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath).</p> <p>If you or your family members have known allergic reactions, make sure you read the label before indulging – especially in a whole block or basket of the stuff. And if you or your family members do experience symptoms of an allergic reaction after eating chocolate, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/allergic-reactions-emergency-first-aid">seek medical attention</a> immediately.</p> <h2>4 take home tips</h2> <p>So, if you are like me and have a weakness for chocolate there are a few things you can do to make the experience a good one.<!-- Below is The Conversation's page counter tag.

I want to eat healthily. So why do I crave sugar, salt and carbs?

<p><em><a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a></em></p> <p>We all want to eat healthily, especially as we reset our health goals at the start of a new year. But sometimes these plans are sabotaged by powerful cravings for sweet, salty or carb-heavy foods.</p> <p>So why do you crave these foods when you’re trying to improve your diet or lose weight? And what can you do about it?</p> <p>There are many reasons for craving specific foods, but let’s focus on four common ones:</p> <h2>1. Blood sugar crashes</h2> <p>Sugar is a key energy source for all animals, and its taste is one of the most basic sensory experiences. Even without specific sweet taste receptors on the tongue, a strong preference for sugar can develop, indicating a mechanism beyond taste alone.</p> <p>Neurons <a href="https://www.nature.com/articles/s41593-021-00982-7">responding to sugar</a> are activated when sugar is delivered to the gut. This can increase appetite and make you want to consume more. Giving into cravings also drives an appetite for more sugar.</p> <p>In the long term, research suggests a high-sugar diet can affect <a href="https://www.bmj.com/content/369/bmj.m2382">mood</a>, digestion and <a href="https://pubmed.ncbi.nlm.nih.gov/33339337/">inflammation</a> in the <a href="https://www.science.org/doi/10.1126/scitranslmed.aay6218?url_ver=Z39.88-2003&amp;rfr_id=ori:rid:crossref.org&amp;rfr_dat=cr_pub%20%200pubmed">gut</a>.</p> <p>While there’s a lot of <a href="https://www.sciencedirect.com/science/article/pii/S0149763402000040?via%3Dihub#aep-section-id23">variation between individuals</a>, regularly eating sugary and high-carb foods can lead to <a href="https://pubmed.ncbi.nlm.nih.gov/30951762/">rapid spikes and crashes</a> in blood sugar levels. When your blood sugar drops, your body can respond by craving quick sources of energy, often in the form of sugar and carbs because these deliver the fastest, most easily accessible form of energy.</p> <h2>2. Drops in dopamine and serotonin</h2> <p>Certain neurotransmitters, such as <a href="https://pubmed.ncbi.nlm.nih.gov/30595479/">dopamine</a>, are involved in the reward and pleasure centres of the brain. Eating sugary and carb-rich foods can trigger the release of dopamine, creating a pleasurable experience and reinforcing the craving.</p> <p>Serotonin, the feel-good hormone, suppresses <a href="https://www.sciencedirect.com/science/article/pii/S1569733910700886">appetite</a>. Natural changes in serotonin can influence daily fluctuations in mood, energy levels and attention. It’s also associated with eating more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5829131/">carb-rich snacks in the afternoon</a>.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21985780/">Low carb diets</a> may reduce serotonin and lower mood. However, a recent systematic review suggests little association between these diets and risk for <a href="https://www.sciencedirect.com/science/article/pii/S0165032722013933?via%3Dihub">anxiety and depression</a>.</p> <p>Compared to men, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4189179/">women tend to crave more carb rich foods</a>. Feeling irritable, tired, depressed or experiencing carb cravings are part of premenstrual <a href="https://pubmed.ncbi.nlm.nih.gov/29218451/">symptoms</a> and could be <a href="https://www.ncbi.nlm.nih.gov/books/NBK560698/">linked to</a> reduced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9928757/">serotonin levels</a>.</p> <h2>3. Loss of fluids and drops in blood sugar and salt</h2> <p>Sometimes our bodies crave the things they’re missing, such as hydration or even salt. A low-carb diet, for example, <a href="https://www.ncbi.nlm.nih.gov/books/NBK537084/">depletes</a> insulin levels, decreasing sodium and water retention.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S1933287419302673">Very low-carb diets</a>, like ketogenic diets, induce “ketosis”, a metabolic state where the body switches to using fat as its primary energy source, moving away from the usual dependence on carbohydrates.</p> <p>Ketosis is often associated with increased urine production, further contributing to potential fluid loss, electrolyte imbalances and salt cravings.</p> <h2>4. High levels of stress or emotional turmoil</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4214609/">Stress</a>, boredom and emotional turmoil can lead to cravings for comfort foods. This is because stress-related hormones can impact our appetite, satiety (feeling full) and food preferences.</p> <p>The stress hormone <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3425607/">cortisol</a>, in particular, can drive cravings for <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">sweet comfort foods</a>.</p> <p>A <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453000000354">2001 study</a> of 59 premenopausal women subjected to stress revealed that the stress led to higher calorie consumption.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/37295418/">A more recent study</a> found chronic stress, when paired with high-calorie diet, increases food intake and a preference for sweet foods. This shows the importance of a healthy diet during stress to prevent weight gain.</p> <h2>What can you do about cravings?</h2> <p>Here are four tips to curb cravings:</p> <p><strong>1) don’t cut out whole food groups.</strong> Aim for a well-balanced diet and make sure you include:</p> <ul> <li> <p><em>sufficient protein</em> in your meals to help you feel full and reduce the urge to snack on sugary and carb-rich foods. Older adults should aim for 20–40g protein per meal with a particular focus on <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/jhn.12838">breakfast and lunch</a> and an overall daily protein intake of at least <a href="https://apps.who.int/iris/handle/10665/43411">0.8g</a> per kg of body weight for <a href="https://pubmed.ncbi.nlm.nih.gov/35187864/">muscle health</a></p> </li> <li> <p><em>fibre-rich foods</em>, such as vegetables and whole grains. These make you feel full and <a href="https://pubmed.ncbi.nlm.nih.gov/32142510/">stabilise your blood sugar</a> levels. Examples include broccoli, quinoa, brown rice, oats, beans, lentils and bran cereals. Substitute refined carbs high in sugar like processed snack bars, soft drink or baked goods for more complex ones like whole grain bread or wholewheat muffins, or nut and seed bars or energy bites made with chia seeds and oats</p> </li> </ul> <p><strong>2) manage your stress levels.</strong> Practise stress-reduction techniques like meditation, deep breathing, or yoga to manage emotional triggers for cravings. Practising <a href="https://pubmed.ncbi.nlm.nih.gov/30570305/">mindful eating</a>, by eating slowly and tuning into bodily sensations, can also reduce daily calorie intake and curb cravings and stress-driven eating</p> <p><strong>3) get enough sleep.</strong> Aim for <a href="https://pubmed.ncbi.nlm.nih.gov/33054337/">seven to eight</a> hours of quality sleep per night, with a minimum of seven hours. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9031614/">Lack of sleep</a> can disrupt hormones that regulate hunger and cravings</p> <p><strong>4) control your portions.</strong> If you decide to indulge in a treat, control your portion size to avoid overindulging.</p> <p>Overcoming cravings for sugar, salt and carbs when trying to eat healthily or lose weight is undoubtedly a formidable challenge. Remember, it’s a journey, and setbacks may occur. Be patient with yourself – your success is not defined by occasional cravings but by your ability to manage and overcome them.<!-- Below is The Conversation's page counter tag.

Resistance occurs when bacteria and fungi survive the effects of one or more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4768623/">antimicrobial drugs</a> due to repeated exposure to these treatments. Antimicrobial resistance is a <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)02724-0/fulltext">global health concern</a>, predicted to cause 10 million deaths yearly by the year 2050.</p> <p>In contrast, dietary nitrate is more targeted. Nitrate eliminates disease-associated bacteria, reduces oral acidity and creates a balanced <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2944498/">oral microbiome</a>. The oral microbiome refers to all the microorganisms in the mouth. Nitrate offers exciting potential as an <a href="https://www.nature.com/articles/s41598-020-69931-x">oral health prebiotic</a>, which can be used to prevent disease onset or limit disease progression.</p> <h2>How many leafy greens for pearly whites?</h2> <p>So how much should we consume daily? As a rule of thumb, a generous helping of spinach, kale or beetroot at mealtimes contains about 6-10 mmol of nitrate and offers immediate health benefits.</p> <p>Work we have done with our collaborators has shown that treating <a href="https://www.nature.com/articles/s41598-020-69931-x">plaque samples</a> from periodontal disease patients with 6.5 mmol of nitrate increased healthy bacteria levels and reduced acidity.</p> <p>For example, consuming <a href="https://aap.onlinelibrary.wiley.com/doi/full/10.1002/JPER.20-0778">lettuce juice</a> for two weeks reduced gum inflammation and increased healthy bacteria levels in patients with gum disease.</p> <p>Growing evidence suggests that nitrate is a cornerstone of oral health. Crunching on a portion of vegetables at mealtimes can help to prevent or treat oral disease and keeps the mouth fresh and healthy.<!-- Below is The Conversation's page counter tag.

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.

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.

Are fish oil supplements as healthy as we think? And is eating fish better?

<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>Fish oil, which contains omega-3 fatty acids, is promoted for a number of health benefits – from boosting our heart health, protecting our brain from dementia, and easing the symptoms of rheumatoid arthritis.</p> <p>But what exactly are omega-3 fats and what does the evidence say about their benefits for keeping us healthy?</p> <p>And if they <em>are</em> good for us, does eating fish provide the same benefit as supplements?</p> <h2>What are omega-3 fats?</h2> <p>Omega-3 fatty acids are a type of polyunsaturated fatty acid. They are essential to consume in our diet because we can’t make them in our body.</p> <p>Three main types of omega-3 fats are important in our diet:</p> <ul> <li> <p>alpha-linolenic acid (ALA), which is found in plant foods such as green leafy vegetables, walnuts, flaxseed and chia seeds</p> </li> <li> <p>eicosapentanoic acid (EPA), which is only found in seafood, eggs (higher in free-range rather than cage eggs) and breast milk</p> </li> <li> <p>docosahexaenoic acid (DHA) is also only found in seafood, eggs (again, higher in free-range eggs) and breast milk.</p> </li> </ul> <p>Omega 3s are key to the structure of our cells, and help keep our heart, lungs, blood vessels, and immune system working.</p> <h2>Eating fish vs taking a supplement</h2> <p>The initial studies suggesting omega-3 fats may have health benefits came from <a href="https://onlinelibrary.wiley.com/doi/epdf/10.1111/j.0954-6820.1976.tb08198.x">observational studies on people eating fish</a>, not from fish oil.</p> <p>So are the “active ingredients” from supplements – the EPA and DHA – absorbed into our body in the same way as fish?</p> <p>An <a href="https://www.sciencedirect.com/science/article/pii/S0002916523281484">intervention study</a> (where one group was given fish and one group fish oil supplements) found the levels of EPA and DHA in your body increase in a similar way when you consume equal amounts of them from either fish or fish oil.</p> <p>But this assumes it is just the omega-3 fats that provide health benefits. There are other <a href="https://www.foodstandards.gov.au/science/monitoringnutrients/afcd/pages/default.aspx">components of fish</a>, such as protein, vitamins A and D, iodine, and selenium that could be wholly or jointly responsible for the health benefits.</p> <p>The health benefits seen may also be partially due to the absence of certain nutrients that would have otherwise been consumed from other types of meat (red meat and processed meat) such as saturated fats and salt.</p> <h2>So what are the benefits of omega 3 fats? And does the source matter?</h2> <p>Let’s consider the evidence for heart disease, arthritis and dementia.</p> <p><strong>Heart disease</strong></p> <p>For cardiovascular disease (heart attacks and stroke), a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003177.pub3/full">meta-analysis</a>, which provides the highest quality evidence, has shown fish oil supplementation probably makes little or no difference.</p> <p>Another <a href="https://www.mdpi.com/2072-6643/12/8/2278">meta-analysis</a> found for every 20 grams per day of fish consumed it reduced the risk of coronary heart disease by 4%.</p> <p>The <a href="https://www.heartfoundation.org.au/getmedia/f1d22267-7381-4513-834b-df317bed9a40/Nutrition_Position_Statement_-_DIETARY_FAT_FINAL-4.pdf">National Heart Foundation</a> recommends, based on the scientific evidence, eating fish rich in omega-3 fats for optimal heart health. <a href="https://apjcn.nhri.org.tw/server/APJCN/17/3/385.pdf">Fish vary in their omega-3 levels</a> and generally the fishier they taste the more omega-3 fats they have – such as tuna, salmon, deep sea perch, trevally, mackeral and snook.</p> <p>The foundation says fish oil may be beneficial for people with heart failure or high triglycerides, a type of fat that circulates in the blood that increases the risk of heart disease and stroke. But it doesn’t recommend fish oil for reducing the risk of cardiovascular diseases (heart attack and stroke).</p> <p><strong>Arthritis</strong></p> <p>For rheumatoid arthritis, <a href="https://arthritis-research.biomedcentral.com/articles/10.1186/s13075-022-02781-2">studies</a> have shown fish oil supplements do provide benefits in reducing the severity and the progression of the disease.</p> <p>Eating fish also leads to these improvements, but as the level of EPA and DHA needed is high, often it’s difficult and expensive to consume that amount from fish alone.</p> <p><a href="https://arthritisaustralia.com.au/managing-arthritis/living-with-arthritis/complementary-treatments-and-therapies/fish-oils/">Arthritis Australia</a> recommends, based on the evidence, about 2.7 grams of EPA and DHA a day to reduce joint inflammation. Most supplements contain about 300-400mg of omega-3 fats.</p> <p>So depending on how much EPA and DHA is in each capsule, you may need nine to 14 capsules (or five to seven capsules of fish oil concentrate) a day. This is about 130g-140g of grilled salmon or mackeral, or 350g of canned tuna in brine (almost four small tins).</p> <p><strong>Dementia</strong></p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Epidemiological studies</a> have shown a positive link between an increased DHA intake (from diet) and a lower risk of developing Alzheimer’s disease, a type of dementia.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0952327807001421?via%3Dihub">Animal studies</a> have shown DHA can alter markers that are used to assess brain function (such as accumulation of amyloid – a protein thought to be linked to dementia, and damage to tau protein, which helps stabilise nerve cells in the brain). But this hasn’t been shown in humans yet.</p> <p>A systematic review of <a href="http://betamedarts.gr/wp-content/uploads/2021/05/31Psychiatriki03_2020.pdf#page=58">multiple studies in people</a> has shown different results for omega-3 fats from supplements.</p> <p>In the two studies that gave omega-3 fats as supplements to people with dementia, there was no improvement. But when given to people with mild cognitive impairment, a condition associated with increased risk of progressing to dementia, there was an improvement.</p> <p>Another <a href="https://pubmed.ncbi.nlm.nih.gov/25446949/">meta-anlayses</a> (a study of studies) showed a higher intake of fish was linked to lower risk of Alzheimers, but this relationship was not observed with total dietary intake of omega-3 fats. This indicates there may be other protective benefits derived from eating fish.</p> <p>In line with the evidence, the <a href="https://www.alzheimers.org.uk/about-dementia/risk-factors-and-prevention/omega-3-and-dementia#:%7E:text=This%20could%20suggest%20that%20taking,its%20own%20may%20not%20be.">Alzheimer’s Society</a> recommends eating fish over taking fish oil supplements.</p> <h2>So what’s the bottom line?</h2> <p>The more people stick to a healthy, plant-based diet with fish and minimal intakes of ultra-processed foods, the better their health will be.</p> <p>At the moment, the evidence suggests fish oil is beneficial for rheumatoid arthritis, particularly if people find it difficult to eat large amounts of fish.</p> <p>For dementia and heart disease, it’s best to try to eat your omega-3 fats from your diet. While plant foods contain ALA, this will not be as efficient as increasing EPA and DHA levels in your body by eating seafood.</p> <p>Like any product that sits on the shop shelves, check the use-by date of the fish oil and make sure you will be able to consume it all by then. The chemical structure of EPA and DHA makes <a href="https://www.sciencedirect.com/science/article/pii/S0924224421005422">it susceptible to degradation</a>, which affects its nutritional value. Store it in cold conditions, preferably in the fridge, away from light.</p> <p>Fish oil can have some annoying side effects, such as fishy burps, but generally there are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3664575/">minimal serious side effects</a>. However, it’s important to discuss taking fish oil with all your treating doctors, particularly if you’re on other medication.<!-- Below is The Conversation's page counter tag.

These 8 health changes could mean you need to eat more vegetables

<p><strong>8 clear signs you're not eating enough vegetables</strong></p> <p>You know veggies are good for you. You may also think you’re eating enough. The truth is, you probably aren’t. Read on to discover the many ways in which your body is telling you that it needs more fruit and vegetables, and what nutrients it craves.</p> <p><strong>How many veggies do you eat, anyway?</strong></p> <p>You may think you eat enough vegetables, but more than likely, you don’t. On average, we only get two servings of vegetables per day.</p> <p>The Australia Dietary Guidelines recommend adults eat five servings of vegetables (one serve equals 75 g of vegetables, approximately half a cup of cooked or one cup of salad veg) and two servings of fruit (one serve equals 150 g, about one apple or two apricots) per day. Skipping key nutrients can seriously affect your overall health.</p> <p><strong>There's a lack of colour on your plate </strong></p> <p>We’ve come a long way since the old meat and two veg. But there are still plenty of people that stick to the simple formula. However, “it isn’t very colourful or loaded with balanced nutrition,” says dietitian Abby Sauer. “And even though they may be favourites, pasta, rice and bread don’t add much colour or much nutrition to your meals in terms of essential vitamins and minerals.”</p> <p><strong>You bruise easily </strong></p> <p>Consuming too little vitamin C can cause you to bruise easily, as well as increase bleeding around gums and slow the healing process. Vitamin C can be consumed by eating red capsicums, kale, red chilli peppers, dark leafy vegetables, broccoli, brussels sprouts and tomatoes.</p> <p><strong>You're tired all the time</strong></p> <p>Deficiency in folate can cause fatigue and anaemia. This B vitamin can be found in dark leafy greens, legumes and starchy vegetables such as black-eyed peas, kidney beans, lima beans, navy beans, asparagus and lentils.</p> <p><strong>That nagging cold won't go away</strong></p> <p>“If you lack vegetables in your diet and the important vitamins they provide, your body may lack the defences it needs to release free radical fighters against viruses,” says Sauer. “Stock your fridge with dark leafy green vegetables, an excellent source of vitamin C, to give your immune system a boost and help shorten your recovery time.”</p> <p><strong>Your memory is foggy</strong></p> <p>While occasional forgetfulness can affect all ages, if you find your brain’s processing speed and efficiency fading as you get older, a lack of nutrients could be the culprit.</p> <p>“Lutein, a nutrient which has been shown in early research to enhance learning and memory, can be found in a variety of vegetables, such as leafy greens, carrots, broccoli, corn and tomatoes,” says Sauer. “Adding a few or all of these vegetables to your weekly meals can provide a helpful and natural brain boost.”</p> <p><strong>Daily stressors are getting harder to handle </strong></p> <p>While stress is an inevitable part of life, how we eat and treat ourselves directly affects our body’s response. “Inflammation is your body’s natural response to stress, so if you’re not handling stress well, inflammation and its damaging effects could be taking place,” says Sauer.</p> <p>“Foods rich in anti-inflammatory compounds, such as unsaturated fatty acids [like salmon and tuna], antioxidants, polyphenols and carotenoids [like green leafy vegetables and bright-coloured capsicums] can help lower the levels of inflammation in the body and increase your mental capabilities to handle life’s curveballs.”</p> <p><strong>You're prone to muscle cramps</strong></p> <p>Fruit and vegetables contain potassium that may prevent muscle cramps, especially if you exercise regularly or spend a lot of time outside in the hot summer months, says dietitian Dr Emily Rubin. “One medium banana has 422 mg of potassium.”</p> <p><strong>Your scales won't budge </strong></p> <p>“Fruit and vegetables have fibre, which makes you feel full so you eat less,” says Rubin. “Most fruit and vegetables are low in kilojoules. Fruit may also help with those sweet cravings. Choosing a bowl of strawberries instead of ice cream can save you 800 kilojoules.”</p> <p><strong>Eat more veggies: Keep them on hand </strong></p> <p>According to medical weight-loss specialist Dr Adrienne Youdim, prep is everything. “Spend a Sunday grilling your favourite veggies. Make them in abundance so that they can be incorporated into your salad or lunchbox,” she says.</p> <p><strong>Eat more veggies: Get one serving per meal </strong></p> <p>“Adding colour and variety to your daily meals with at least one serving of fruit or vegetables per meal can be as easy as thawing out a bag of frozen green beans, slicing up an apple or adding a bowl of colourful berries,” says Sauer.</p> <p><strong>Eat more veggies: Buy frozen</strong></p> <p>“Many people avoid fresh vegetables because they go off before they get a chance to eat them,” says clinical oncology dietitian Crystal Langlois. “Buying frozen vegetables is a great alternative that is convenient and easy. If all the prep work and chopping scares you, many supermarkets carry pre-chopped items in both the frozen and fresh produce areas.”</p> <p>And if you still have that inner-kid kicking and screaming to avoid eating your veggies, blend your veggies into shakes or smoothies. “The taste of vegetables is easily masked in shakes or smoothies by using fruit and fruits juice,” says Langlois. “Small diced mushrooms can be incorporated into hamburgers or Bolognese, as well.”</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/8-clear-signs-youre-not-eating-enough-vegetables?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

How to eat oysters like a pro

<p>According to most etiquette rules, slurping your food (and eating with your hands) at the table is a big no-no. But when learning how to eat oysters, those established table manners can be thrown out the window. Whether you’re at a coastal seafood shack or a five-star restaurant, oysters demand to be eaten with your hands.</p> <p>And unlike other shellfish and crustaceans, oysters can (and should!) be eaten raw. Here’s how to eat those freshly shucked oysters the right way.</p> <p><strong>What are oysters?</strong></p> <p>Oysters are shellfish (bivalve mollusks, to be exact) that can be found in saltwater seas, estuaries and oceans around the world. Oyster shells are shucked (the method used to open the oyster to access the fresh meat inside), and they are popularly served raw on the half shell, but can also be battered and deep-fried, steamed, grilled or used in various seafood dishes, such as seafood pastas or chowder.</p> <p>The insides of oyster shells are lined with a shiny, iridescent layer called ‘nacre’, better known to most jewellery aficionados as mother of pearl (it’s what some oysters use to make pearls). However, it’s important to note that not all oysters do this, which is why naturally harvested pearls are exceedingly rare.</p> <p><strong>How to eat oysters</strong></p> <p>If you’ve never tried eating freshly shucked oysters before, you’re in for a real treat. They’re salty, briny and taste a bit like the ocean. Here’s how to eat oysters.</p> <p><span style="text-decoration: underline;"><em>Select your oysters</em></span></p> <p>Unless you live in a seaside town where you can buy fresh oysters straight from the source, your first raw oyster experience should be at a reputable restaurant or seafood bar. This will allow you to taste a variety of oysters so you can determine your preferences. Most restaurant waiters will tell you the region where your oysters were caught.</p> <p><strong>Loosen the oyster from the shell </strong></p> <p>First, use an oyster fork or another small utensil to gently lift the oyster from the shell, being careful not to spill any of the flavourful liquid. This ensures the oyster meat has been fully detached from its shell. If your oyster has been professionally shucked, it should lift right up.</p> <p><strong>Dress your oysters (optional)</strong></p> <p>Oysters don’t need any help being delicious, which is why many people love slurping them directly out of their shells the moment they’re shucked. If it’s your first time eating oysters, try them plain so you can fully appreciate what they taste like naked. Once you understand their flavour, you can feel free to dress an oyster on its shell with sauces, seasonings and toppings.</p> <p>Restaurants often present oysters on a bed of ice and with common accouterments, such as lemon wedges, hot sauce, cocktail sauce, mignonette and horseradish.</p> <p><strong>Tilt and slurp</strong></p> <p>Tilt the shell straight into your mouth, letting the oyster meat and liquor slide into your mouth, just like you were taking a shot of alcohol. Take a few moments to savour the flavour, chewing lightly if you care to – oysters are tender enough that they don’t require chewing and can be gulped down as is.</p> <p><strong>Oyster FAQs</strong></p> <p><span style="text-decoration: underline;"><em>What do oysters taste like?</em></span></p> <p>“The way an oyster tastes varies depending on species,” says Jasmine Norton, chef and owner of The Urban Oyster. “Some are more salty than others, depending on the region where they are sourced.” While every oyster has its own unique flavour profile reflective of the waters it’s grown in, they can all be described as briny with a light sweetness.</p> <p><span style="text-decoration: underline;"><em>Do you chew oysters?</em></span></p> <p>“Pending the preparation and size of the oyster, you can chew or swallow whole,” says Norton. “For example, I would chew a grilled oyster, but swallow a raw one. If I am chewing, my rule of thumb is no more than two chews.”</p> <p><span style="text-decoration: underline;"><em>Are oysters alive when you eat them?</em></span></p> <p>If you’re eating freshly shucked oysters on the half shell, the answer is yes. “Oysters should be eaten the day they are shucked, which means they are still alive. Alive means fresh,” says Norton.</p> <p><span style="text-decoration: underline;"><em>How do you prepare fresh oysters to eat?</em></span></p> <p>If you’re enjoying your oysters at home, you’ll need to shuck them yourself right before eating them. Shucking oysters requires special equipment and a good amount of skill – and it can be dangerous if you don’t know what you’re doing. So, buy an oyster shucking set that includes an oyster knife and protective gloves, and be sure to watch an instructional video to learn precisely how to do it.</p> <p><span style="text-decoration: underline;"><em>Should you drain oysters before eating?</em></span></p> <p>“No, definitely not!” exclaims Norton. “This is where all the good salty flavour comes from.” If you’re cooking with oysters, reserve the oyster liquor and add it to your dish. If eating them raw, slurp the liquor along with the oyster meat.</p> <p><span style="text-decoration: underline;"><em>How do you know if an oyster is fresh?</em></span></p> <p>It’s easy to tell whether an oyster is fresh. “Oysters are very telling when they’re not fresh,” Norton says. “The smell radiates! When you know, you know.”</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/how-to-eat-oysters-like-a-pro" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Does it matter what time of day I eat? And can intermittent fasting improve my health? Here’s what the science says

Their <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">access to food</a> relied on successful hunting, fishing, and the availability of wild plants.</p> <p>Over time, the development of modern agriculture and the transition to industrialised societies <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">changed our regular eating patterns</a>, shifting our dinner time to later in the day to accommodate work schedules.</p> <p>Today, with access to an abundance of food, we rarely experience prolonged periods of fasting, except for weight loss or religious practices. It’s <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">now common</a> to have four or more meals a day, with the most calories consumed later in the day. Frequent snacking is also common, over a window of around 15 hours.</p> <p>However, research increasingly shows our health is not only affected by what and how much we eat, but also <em>when</em> we eat.

It can also tell us the best time to eat.</p> <p>Our body is biologically prepared to have food during the day. Food digestion, nutrient uptake and energy metabolism is optimised to occur when we’re supposed to be active and eating.</p> <p>Working against this default stage, by regularly eating when we’re supposed to sleep and fast, can compromise these processes and impact our health. <a href="https://pubmed.ncbi.nlm.nih.gov/31813351/">Erratic eating patterns</a>, including late-night meals, have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/36198293/">weight gain</a> and a greater risk of metabolic disease.</p> <p>Shift-workers, for example, and people who work evening, night or rotating shifts, have a <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">higher risk</a> of obesity, heart disease and diabetes.</p> <p>But adopting an eating pattern that aligns with our circadian rhythm can reduce these risks.</p> <h2>So can intermittent fasting help?</h2> <p>Nutritional interventions are increasingly focused not only on “what” we eat but also “when”. Intermittent fasting is one way to restrict the timing, rather than the content, of what we eat.</p> <p>There are <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">several types</a> of intermittent fasting, one of which is time-restricted eating. This means eating all our calories in a consistent 8-12 hour, or even shorter, interval each day.</p> <p>But is it backed by evidence?</p> <p>Most of what we know today about intermittent fasting and time-restricted eating is from <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">mouse studies</a>, which demonstrate remarkable weight loss and overall health benefits associated with these types of dietary interventions.</p> <p>However, some aspects of mouse physiology can be different to humans. Mice need to eat more frequently than humans and even a short period of fasting has a more significant physiological impact on mice. One day of fasting in mice leads to a 10% <a href="https://www.sciencedirect.com/science/article/pii/S2212877820301320">loss of body weight</a>, whereas humans would need to fast for 14 days to achieve <a href="https://pubmed.ncbi.nlm.nih.gov/30881957/">similar results</a>. This makes a direct translation from mice to humans more complicated.</p> <p>While health benefits of <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">intermittent fasting</a> and <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2114833">time-restricted eating</a> have also been observed in humans, the findings in respect of weight loss are less clear. Current data suggest only modest, if any, weight loss in human participants who undergo these diet regimens when compared to calorie-restricted diets.</p> <p>Drawing <a href="https://pubmed.ncbi.nlm.nih.gov/35834774/">definitive conclusions</a> in humans may be more <a href="https://pubmed.ncbi.nlm.nih.gov/32480126/">difficult</a> because of the small sample sizes and individual differences in metabolism, variations in study design (such as the use of different protocols with varying times and duration of food restriction), and participants not complying with their instructions.</p> <h2>Health benefits could be due to eating fewer calories</h2> <p>Most studies describing the health benefits of <a href="https://pubmed.ncbi.nlm.nih.gov/33466692/#:%7E:text=and%20Future%20Perspectives-,Time%2DRestricted%20Eating%20and%20Metabolic%20Syndrome%3A%20Current%20Status%20and%20Future,doi%3A%2010.3390%2Fnu13010221.">time restricted eating</a> or <a href="https://pubmed.ncbi.nlm.nih.gov/27569118/">intermittent fasting</a> also found these diets were accompanied by calorie restriction: reducing the time of food access implicitly leads people to eat less.</p> <p>Studies that controlled calorie intake did not detect any more benefits of intermittent fasting than <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2623528">calorie restriction</a> alone.</p> <p>The weight loss and health benefits observed with intermittent fasting is likely attributed due to the resultant reduction in <a href="https://pubmed.ncbi.nlm.nih.gov/34135111/">calorie intake</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/32986097/">Similar findings</a> have been reported for time-restricted eating.</p> <h2>Benefit of following our body clock</h2> <p>Nevertheless, time-restricted eating offers additional health benefits in humans, such as improved glucose metabolism and blood pressure, even without differences in calorie intake, in particular when restricted to the <a href="https://pubmed.ncbi.nlm.nih.gov/29754952/">earlier part of the day</a> (that is, when having a six-hour eating window with dinner before 3pm).</p> <p>Restricting food intake to the daytime for shift-workers <a href="https://pubmed.ncbi.nlm.nih.gov/28635334/">can alleviate</a> metabolic differences caused by shift-work, whereas this effect is not observed when food intake is restricted to <a href="https://www.science.org/doi/10.1126/sciadv.abg9910">nighttime</a>.</p> <p>One idea is that consuming food early, in alignment with our circadian rhythm, helps to <a href="https://pubmed.ncbi.nlm.nih.gov/28578930/">synchronise our circadian clock</a>. This restores the rhythm of our autonomous nervous system, which regulates essential functions such as breathing and heart rate, to keep our physiology “tuned”, as it was shown <a href="https://www.pnas.org/doi/10.1073/pnas.2015873118">in mice</a>.</p> <p>While there’s much still to learn from research in this field, the evidence suggests that to maintain a healthy weight and overall wellbeing, aim for regular, nutritious meals during the day, while avoiding late-night eating and frequent snacking.<!-- Below is The Conversation's page counter tag.

What to eat before bed if you want a good night’s sleep

<p><strong>What to eat before bed</strong></p> <p>It’s after 8 pm and you can feel your stomach grumbling. Should you stick it out until morning or head to the kitchen? Night-time eating tends to get a bad reputation – people often worry it causes weight gain, heartburn, indigestion or all three. But it all depends on what you reach for, says nutritionist Nishta Saxena.</p> <p>Saxena says there isn’t a clear-cut time of day that we have to stop eating. Studies have found that it’s not when you’re eating, but how much and what you’re eating which matters. Super salty snacks at the end of the day can, for example, make you dehydrated and interrupt your sleep – and they’re not the only culprits that can affect whether you have a good night’s rest.</p> <p>In general, it’s best to eat small portions before bed. Also try to stay away from foods high in protein or fat, which can be harder for our bodies to digest and can interrupt the natural cadence of our systems, which slow down for the night by producing sleep-inducing hormones like melatonin. Excessive sugar can also act like a stimulant – a bad choice if you’re trying to catch some Zzzs.</p> <p>Saxena suggests eating something that’s high in carbohydrates, which can promote sleep and help you to relax. This is because carbs don’t require as much blood flow or work from your body to digest and are therefore unlikely to interrupt your sleep. If you find yourself with an after-dinner case of the munchies, follow these tips on what to eat before bed.</p> <p><strong>Kiwis</strong></p> <p>Kiwis can help to promote sleep because they are rich in serotonin and antioxidants (such as Vitamins C and E). Serotonin helps to make you feel relaxed and certain antioxidants have sleep-promoting qualities.</p> <p>Plus, these fuzzy fruits are extremely high in vitamin C and our bodies can digest them quickly, says Saxena. They also support heart and digestive health as well as natural immunity.</p> <p><strong>Tart cherries</strong></p> <p>Tart cherries and tart cherry juice contain concentrated amounts of melatonin, a hormone that helps your body regulate sleep-wake cycles, says Saxena. Studies show that they can help to reduce insomnia, plus they also contain other sleep-inducing agents like tryptophan (a precursor of serotonin).</p> <p>Since tart cherries can be a little bit harder to find than other fruits, Saxena suggests keeping some in your freezer and using them to make a smoothie.</p> <p><strong>Nuts</strong></p> <p>Nuts are great for a variety of health benefits, says Saxena, and they’re also a good late-night snack. Just don’t dish out a whole cup of nuts, she warns, because they do contain surprising amounts of protein and fat.</p> <p>In particular, she recommends walnuts and almonds – they contain natural melatonin as well as magnesium, which has the potential to reduce insomnia in adults.</p> <p><strong>Popcorn</strong></p> <p>While pre-packaged microwave popcorn most likely contains too much salt to be a good bedtime snack, popping your own can satisfy people who are craving snack foods like chips.</p> <p>Popcorn is also relatively filling – just don’t drown your bowl in butter and salt.</p> <p><strong>Yoghurt</strong></p> <p>Dairy products, while not consumed by everyone, have a lot of components that stimulate sleep, says Saxena. Something like yoghurt doesn’t require a lot of digestive processes, and even full fat yoghurt doesn’t have a ton of fat in it, making it easy to digest.</p> <p>Plus, it’s filled with amino acids, like tryptophan, which promote sleep.</p> <p><strong>Green bananas</strong></p> <p>Saxena says a greenish banana, “almost the colour of a tulip stem,” is a great evening snack. At this point, the banana is full of starch, which means it hasn’t yet become sugar, and this can be great for our gut bacteria and also helps to promote sleep.</p> <p>She adds that the banana should be firm and have a tiny bit of yellow in the midsection. If it has black spots, it’s too ripe to help with sleep and won’t provide a benefit.</p> <p><strong>Warm milk</strong></p> <p>The benefits of warm milk for sleep are well-documented, says Saxena. This is in part because milk contains tryptophan, an amino acid that promotes sleep. Warm fluids in general can relax our digestive muscles.</p> <p>“It can be a self-care moment when you’re having something warm,” Saxena says. “Your hands are wrapped around the mug and it’s a sensory experience.”</p> <p><strong>Cottage cheese</strong></p> <p>While cottage cheese has lots of protein, it also has the benefits of dairy, including amino acids, that help to promote sleep. It’s also nutrient-dense, containing calcium, magnesium, iron, and phosphorus, which are essential for bodily function.</p> <p>It can also be a good late-night snack for athletes, because it’s high in the protein casein, which helps to reduce muscle breakdown overnight. Still, stay away from other cheeses before bed – most are very high in fat and easy to overeat, warns Saxena.</p> <p><strong>Oatmeal</strong> </p> <p>While people often think of oatmeal as a breakfast food, oats are high in melatonin and so can make a good bedtime snack. Like dairy products, oats also contain the amino acid tryptophan.</p> <p>You can also spice up your oatmeal with many of the other foods that are okay to eat before bed – tart cherries, yogurt, or almond butter, for example.</p> <p><strong>Pasta</strong></p> <p>If you’re really hungry, try some pasta – but keep the portion small and be careful to not load your dish with toppings that are high in protein or fat.</p> <p>For example, you don’t want to have a super-cheesy meatball pasta before bed, says Saxena. But a small serving of plain pasta with pesto sauce might do the trick.</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/sleep/what-to-eat-before-bed-if-you-want-a-good-nights-sleep?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

This is the healthiest time to eat dinner

<p><strong>When should we eat dinner?</strong></p> <p>Recent research highlights that the timing of our meals, particularly the last meal of the day, can significantly affect our health. The story is not merely about what we consume, but also about when we do so.</p> <p>The debate about dinner timing finds substantial scientific backing with a Brigham and Women’s Hospital (BWH) study published in Cell Metabolism in October 2022, suggesting that early dinners could have more health benefits than previously believed.</p> <p><strong>The science of early dinner</strong></p> <p>Senior author of the study, Dr Frank A. J. L. Scheer, Director of the Medical Chronobiology Programme in BWH’s Division of Sleep and Circadian Disorders, explained the study’s objective in a press release: “We wanted to test the mechanisms that may explain why late eating increases obesity risk.”</p> <p>The study defined an early dinner as a meal consumed three to four hours before bedtime, aligning with our body’s circadian rhythm. This time management allows the body to efficiently digest food, process nutrients, and smoothly transition into a fasting mode during sleep, facilitating essential restorative processes (and arguably better sleep, according to some experts).</p> <p><strong>The benefits of an early-bird dinner</strong></p> <p>The BWH study discovered stark differences in metabolic profiles of early and late diners. Early diners demonstrated lower blood glucose levels, improved fat-burning capacity, better sleep quality, and higher energy levels. Meanwhile, late dinners led to increased hunger, slower calorie burning, and elevated fat storage, posing risks for conditions like diabetes and cardiovascular disease.</p> <p>Further reinforcing these findings, a study published in Obesity Reviews examined the effects of energy intake distribution on weight loss. This systematic review evaluated nine randomised controlled trials and concluded that focusing on earlier energy intake resulted in significantly greater short-term weight loss. Alongside weight loss, improvements were observed in insulin resistance, fasting glucose and LDL cholesterol levels.</p> <p><strong>Implications and recommendations </strong></p> <p>These findings hold considerable implications for those dealing with health conditions like diabetes, thyroid issues, polycystic ovarian disease, and cardiovascular disorders. The studies spotlight the importance of early and light dinners, thus prompting a re-evaluation of our dinner schedules and meal planning.</p> <p>As first author Dr Nina Vujovic put it: “Does the time that we eat matter when everything else is kept consistent? And we found that eating four hours later makes a significant difference for our hunger levels, the way we burn calories after we eat, and the way we store fat.”</p> <p><strong>Tailoring dinner time to fit your schedule </strong></p> <p>The exact timing of dinner isn’t a one-size-fits-all scenario, as people’s routines vary widely. Nutritionist Maya Feller emphasises that our schedules – ranging from traditional nine-to-five to round-the-clock – are pivotal when considering “ideal” meal times. Therefore, finding a dinner time that seamlessly fits into your schedule is essential, rather than adhering to a strict, potentially unfeasible timetable.</p> <p>Dr Wendy Bazilian offers insightful tips for those whose routines may not accommodate an early dinner. She recommends consuming meals or snacks every three to five hours. This regular eating pattern can help stabilise blood sugar levels, preventing the onset of hunger pangs and energy lulls.</p> <p>Furthermore, it’s advantageous to leave a gap of two to three hours between your last meal and bedtime. This gap ensures your body has sufficient time for most of the digestion process – letting you get adequate rest and repair during sleep.</p> <p><strong>Health benefits</strong></p> <p>The takeaway from these studies is clear: an earlier dinnertime might confer multiple health benefits, from metabolic health enhancement to improved sleep quality. It’s time to reconsider not just the contents of your plate, but also the clock.</p> <p>As research grows, it’s becoming apparent that understanding the interplay between our eating habits, their timing, and the body’s internal clock should be an integral part of our health strategies. After all, leading a healthy lifestyle isn’t solely about counting calories but also understanding when and how to fuel our bodies.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/food-home-garden/this-is-the-healthiest-time-to-eat-dinner" target="_blank" rel="noopener">Reader's Digest</a>. </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>

This eating habit is key to losing weight

<p>New research has found the time of day you eat is key to losing weight.</p> <p>The findings reveal that your best efforts to cut back may prove ineffective if you’re not timing your meals correctly.</p> <p>A study found that mice lost weight when they were given a reduced calorie diet and only ate during the day.</p> <p>Rodents who consumed the same diet but ate at night did not reap the same results.</p> <p>Lead author of the study, Dr Joseph Takahashi, said, “Translated into human behaviour, these studies suggest that dieting will only be effective if calories are consumed during the daytime when we are awake and active.”</p> <p>Dr Takahashi added, “They further suggest that eating at the wrong time at night will not lead to weight loss even when dieting.”</p> <p>Scientists from the University of Texas Southwestern Medical Center also believe the timing of meals is important as it also affects circadian rhythms, the body’s 24-hour clock.</p> <p>They have highlighted how the research may explain how dietary habits impact lifespan.</p> <p>The study observed this by testing the day/night cycles of mice under different feeding schedules.</p> <p>Two groups of mice were fed at the wrong time during their normal cycle. One group was given 30 per cent less calories and the other group had unlimited food, but both groups were more active at night.</p> <p>Various research has associated sleep problems with an increased risk of obesity.</p> <p>“'It has been known for decades that calorie restriction prolongs lifespan in animals, but these types of studies are very difficult to conduct because they required manual feeding of subjects over many years," Dr Takahashi said</p> <p>“This automated system, which can be scaled up for large and very long longevity studies, provides the means to address open questions about what mechanisms extend lifespan in mammals.”</p> <p><em>Image credit: Shutterstock</em></p> <p><em>The research was published in the journal Cell Metabolism. </em></p>

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 ways to eat healthier without counting calories

<p>How do you choose what to eat? Is it the aroma wafting from the kitchen that tempts you or the sight of decadent frosting on a springy cake? We tend to rely only on one or two senses, like taste and sight, when picking and eating food… but if we engage all five of our senses when deciding what to put on our plates it might just be the secret to making healthier food choices.</p> <p><strong>Sight</strong></p> <p>It’s probably not much of a surprise to hear that sight is perhaps the most important sense we use when we choose certain foods over others – just scrolling past a mouth-watering recipe on Facebook (we’re sorry) can make you hungrier. Presentation matters. The more appealing it looks, the more likely you’re going to eat it and enjoy it. So make an effort to present your healthy meals in a creative, fun and interesting way – you will satisfy both your sense of sight and your tummy.</p> <p><strong>Touch</strong></p> <p>A 2013 study in the journal Flavour experimented with how touch influences our food taste. In one experiment, they found people rated yoghurt denser and tastier when it was served in a heavy bowl rather than a lighter one. Co-author of the study Charles Spence said the tactile experience leads us to focus more intently on what we're eating and consequently we’re more aware when we’re truly full.</p> <p><strong>Hearing</strong></p> <p>One of the biggest eating mistakes is having your meal in front of the tele. When you’re engrossed with the sights and sounds on a screen, you tend not to focus on what you’re eating and before you know it, the whole plate is clean! Concentrate on eating during mealtimes and you’ll be less likely to overindulge.</p> <p><strong>Smell</strong></p> <p>Our nose tells us if a meal smells good but that tends to be the end of it. Deeply inhaling the aromatic scents of food can help you feel more satisfied with food even though you’re eating less. In a 2012 study, participants ate vanilla custard in a lab while researchers released a cream aroma at different levels of intensity. During the strongest aroma, the participants took smaller bites and consumer 10 per cent less of the treat. Study co-author René de Wijk, PhD, explained: “We tend to regulate intensely pungent sensations by reducing our intake. As a result, we can eat less but still feel satisfied."</p> <p><strong>Taste</strong></p> <p>Give any dish a generous sprinkling of salt will amp up the flavour but we know by now that it isn’t the best seasoning for our bodies. To get the same deliciousness from your dishes, chefs recommend adding umami. A review in Nutrition and Health found that adding umami-rich foods (such as parmesan, shiitake mushrooms and tomatoes) to your meals instead of high-fat extras and salt can reduce fat content by up to 30 per cent and sodium by 40 per cent – and no, the taste wasn’t comprised. </p> <p><em>Image credits: Getty Images</em></p>

Why does my dog eat grass? And when is it not safe for them?

<p><a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, <em><a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em> and <a href="https://theconversation.com/profiles/joshua-zoanetti-1439474">Joshua Zoanetti</a>, <em><a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>Have you ever wondered why your dog is eating your beautifully cropped lawn or nibbling at the grass at the dog park?</p> <p>Eating grass is a common behaviour in pet dogs. Some surveys show <a href="http://raw-feeding-prey-model.fr/wp-content/uploads/2019/03/WhydogogsandcatseatgrassGrassVetMed2008-2.pdf">up to 80%</a> of guardians notice their dog regularly snacking on the grass.</p> <p>Grass eating isn’t a new behaviour either, or only done by our new designer dog breeds. Studies in Yellowstone National Park show plant matter (mostly grass) is found in up to <a href="https://academic.oup.com/jn/article/136/7/1923S/4664711">74% of wolf scats</a>, suggesting the behaviour is possibly inherited from the beginning of doggy time.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=390&fit=crop&dpr=1 600w, https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=390&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=390&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=490&fit=crop&dpr=1 754w, https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=490&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/529490/original/file-20230601-21796-wl09tw.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=490&fit=crop&dpr=3 2262w" alt="" /></a><figcaption></figcaption></figure> <h2>So why does my dog eat the grass?</h2> <p>A lot of people think dogs eat grass when they have a sore stomach, believing grass causes dogs to vomit. This is probably not the case; a study with <a href="https://www.une.edu.au/__data/assets/pdf_file/0019/32446/bjone-brown-price-grass-eating20patterns-raan-2007.pdf">12 dogs that ate grass daily</a> found there were few vomiting episodes and the ones that did occur came after the dog had eaten a meal.</p> <p>And if a dog has a mild gastrointestinal disturbance because of something they’ve been fed, they are in fact <a href="https://www.sciencedirect.com/science/article/abs/pii/S0168159109003311">less likely</a> to eat grass than if they are fed a normal diet.</p> <p>Other theories include that dogs eat grass because they want a laxative or that it provides roughage in their diet (get that fibre!).</p> <p>Like the vomiting discussed above, there is little to no scientific proof for most of these theories. For example, in the study of <a href="https://www.une.edu.au/__data/assets/pdf_file/0019/32446/bjone-brown-price-grass-eating20patterns-raan-2007.pdf">12 dogs mentioned above</a>, all of them were wormed and had no previous digestive problems. Yet all 12 still happily ate grass (709 times).</p> <p>Their main finding was that when the dog had not yet had their daily meal, they were more likely to eat grass. In short, the hungrier the dog, the more likely they were to eat some grass.</p> <p>The answer to why your dog eats grass may simply be: because they like to. Your dog may be bored, and chewing on grass is something to do.</p> <p>Maybe your dog just enjoys eating grass. Ripping grass from the ground can be satisfying. The texture and taste of grass offers something different to what they usually eat. You may even notice they prefer grass in certain seasons; perhaps fresh spring grass a favourite delicacy.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=401&fit=crop&dpr=1 600w, https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=401&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=401&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=504&fit=crop&dpr=1 754w, https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=504&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/529491/original/file-20230601-23190-7g4mhp.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=504&fit=crop&dpr=3 2262w" alt="" /></a><figcaption></figcaption></figure> <h2>Is there any reason why you shouldn’t let your dog eat grass?</h2> <p>Well, yes, there are several.

"Makes us feel sick": Angry vegan slams meat-eating neighbours

<p>A letter from a vegan neighbour has gone viral, as they asked a close-by resident to close their windows while they cook meat. </p> <p>The hand-written note was published on a community Facebook page for the Perth northern coastal suburb of Burns Beach, and was labelled as an "Important message" for the recipient to "Please take seriously".</p> <p>The note began, "Hello, neighbour."</p> <p>"Could you please shut your side window when cooking, please?"</p> <p>"My family are vegan (we eat only plant-based food), and the smell of the meat you cook makes us feel sick and upset."</p> <p>"We would appreciate your understanding."</p> <p>The letter went viral not long after it was posted, and drew in a range of divided comments. </p> <p>Some people believed the request was a ridiculous ask, with many people wondering where they draw the line when it comes to catering for others. </p> <p>"I'd understand if they were smoking cigarettes and the smoke and smell was spreading and affecting the family's health," one person wrote.</p> <p>"But not liking the smell of meat, this isn't really a good reason to ask someone to close their windows."</p> <p>"What does she do when she takes the kids to the park, and people are cooking BBQs? Ask them to stop cooking. Audacity."</p> <p>Others thought the request was reasonable, and praised the writer's politeness. </p> <p>"I feel like this was a genuinely polite letter, and it’s true the smell of meat is overpowering," one person wrote.</p> <p>"It would be nice to see some respect for your neighbours, and not publicly trying to shame them for holding strong ethical morals."</p> <p>Another put it simply, "Be vegan. Eat meat. Each to their own!"</p> <p>One commenter suggested the recipient resort to good old neighbourly pettiness, encouraging them to "Write back and say you're offended and sad by what they said about your cooking and could they please move to a different room as you would appreciate their understanding."</p> <p><em>Image credits: Facebook</em></p>

What to eat when you have COVID – and why reaching for the chicken soup is not a bad idea

<p>Got COVID? Again?</p> <p>Deciding what to eat can be mentally taxing, especially when you are not feeling well. However, our diet plays a role in preventing and managing poor health, including COVID.</p> <p>Having a healthy diet is associated with a <a href="https://gut.bmj.com/content/70/11/2096">reduced risk of COVID</a>. And, if you do have COVID, a healthy diet is associated with <a href="https://gut.bmj.com/content/70/11/2096">milder symptoms</a>.</p> <h2>What should I eat during COVID infection?</h2> <p>When we are sick it can be challenging to even think about food. However, the best way to fight the infection is by providing your body with foods that best support you to <a href="https://www.emro.who.int/nutrition/covid-19/nutrition-advice-for-adults-during-the-covid-19-outbreak.html">heal</a>.</p> <p>Fresh fruit, vegetables, whole grains and various forms of protein are broken down into substances by the body to support your immune system. </p> <p><a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">The Australian Guide to Healthy Eating</a> suggests we eat a variety of fresh foods every day including:</p> <ul> <li> <p>two serves of fruit and five serves of vegetables</p> </li> <li> <p>whole grains, such as wholemeal pasta, brown rice or wholemeal bread</p> </li> <li> <p>healthy fats, such as avocado or olive oil </p> </li> <li> <p>meat and meat alternatives (such as lean beef, chicken, tofu or legumes) and dairy (such as cheese or milk). </p> </li> </ul> <p>Eating these kinds of foods every day helps provide our body with the nutrients required to fight infections and remain healthy. </p> <p><a href="https://doi.org/10.3390/nu10050587">Avoiding processed and ultra processed foods</a> is also encouraged due to the high levels of salt and sugar and lack of nutrition found in these types of foods.</p> <h2>What about chicken soup or similar?</h2> <p>A great way to get all the nutrition your body requires when sick with COVID is through homemade chicken soup, chicken avgolemono, chicken congee or other similar dishes. </p> <p>Why? Here are four good reasons:</p> <p>1. It’s easy and cheap to make</p> <p>The great thing about chicken soup is you can pop it in one pan (or into a slow cooker), throw all the ingredients in together and let it simmer away. </p> <p>While the ingredients in chicken soup pack a powerful nutritional punch, they don’t cost the Earth.</p> <p>2. It’s easy to absorb</p> <p>The boiling process releases the <a href="https://doi.org/10.3390/foods10071456">nutritional elements</a> found in the ingredients and aids in digestion and absorption of these vital nutrients. </p> <p>3. It’s full of vitamins and minerals</p> <p><a href="https://scuj.journals.ekb.eg/article_119478.html">Essential vitamins and minerals</a> found in chicken soup include: iron, magnesium, sodium, potassium, calcium, chromium, copper, zinc, vitamin A, vitamin C, vitamin B6 and vitamin B12. </p> <p>4. It’s flavoursome and powerful</p> <p>The tasty flavour of chicken soup is enhanced by the <a href="https://doi.org/10.1080/10942912.2017.1291678">seventeen different amino acids</a> found in chicken soup. These amino acids also provide strength for your <a href="https://pubmed.ncbi.nlm.nih.gov/17403271/">immune system.</a></p> <h2>Nutrition can support immune health but it’s not the only answer</h2> <p>The best way to treat and manage a COVID infection is to avoid it in the first place.
