The voice in your head may help you recall and process words. But what if you don’t have one?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/derek-arnold-106381">Derek Arnold</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Can you imagine hearing yourself speak? A voice inside your head – perhaps reciting a shopping list or a phone number? What would life be like if you couldn’t? Some people, including me, cannot have imagined visual experiences. We cannot close our eyes and conjure an experience of seeing a loved one’s face, or imagine our lounge room layout – to consider if a new piece of furniture might fit in it. This is called “<a href="https://theconversation.com/a-blind-and-deaf-mind-what-its-like-to-have-no-visual-imagination-or-inner-voice-226134">aphantasia</a>”, from a Greek phrase where the “a” means without, and “phantasia” refers to an image. Colloquially, people like myself are often referred to as having a “blind mind”. While most attention has been given to the inability to have imagined visual sensations, aphantasics can lack other imagined experiences. We might be unable to experience imagined tastes or smells. Some people cannot imagine hearing themselves speak. A <a href="https://www.sciencealert.com/we-used-to-think-everybody-heard-a-voice-inside-their-heads-but-we-were-wrong">recent study</a> has advanced our understanding of people who cannot imagine hearing their own internal monologue. Importantly, the authors have identified some tasks that such people are more likely to find challenging. <h2>What the study found</h2> Researchers at the University of Copenhagen in Denmark and at the University of Wisconsin-Madison in the United States <a href="https://journals.sagepub.com/doi/10.1177/09567976241243004">recruited 93 volunteers</a>. They included 46 adults who reported low levels of inner speech and 47 who reported high levels. Both groups were given challenging tasks: judging if the names of objects they had seen would rhyme and recalling words. The group without an inner monologue performed worse. But differences disappeared when everyone could say words aloud. Importantly, people who reported less inner speech were not worse at all tasks. They could recall similar numbers of words when the words had a different appearance to one another. This negates any suggestion that aphants (people with aphantasia) simply weren’t trying or were less capable. <h2>A welcome validation</h2> The study provides some welcome evidence for the lived experiences of some aphants, who are still often told their experiences are not different, but rather that they cannot describe their imagined experiences. Some people feel anxiety when they realise other people can have imagined experiences that they cannot. These feelings may be deepened when others assert they are merely confused or inarticulate. In my own <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2024.1374349/full">aphantasia research</a> I have often quizzed crowds of people on their capacity to have imagined experiences. Questions about the capacity to have imagined visual or audio sensations tend to be excitedly endorsed by a vast majority, but questions about imagined experiences of taste or smell seem to cause more confusion. Some people are adamant they can do this, including a colleague who says he can imagine what combinations of ingredients will taste like when cooked together. But other responses suggest subtypes of aphantasia may prove to be more common than we realise. The authors of the recent study suggest the inability to imagine hearing yourself speak should be referred to as “anendophasia”, meaning without inner speech. Other authors had suggested <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8551557/">anauralia</a> (meaning without auditory imagery). Still other researchers have referred to all types of imagined sensation as being different types of “imagery”. Having <a href="https://www.sciencedirect.com/science/article/abs/pii/S0010945222000417">consistent names</a> is important. It can help scientists “talk” to one another to compare findings. If different authors use different names, important evidence can be missed. <h2>We have more than 5 senses</h2> Debate continues about how many senses humans have, but some scientists reasonably argue for a <a href="https://www.sensorytrust.org.uk/blog/how-many-senses-do-we-have#:%7E:text=Because%20there%20is%20some%20overlap,sensation%20of%20hunger%20or%20thirst.">number greater than 20</a>. In addition to the five senses of sight, smell, taste, touch and hearing, lesser known senses include thermoception (our sense of heat) and proprioception (awareness of the positions of our body parts). Thanks to proprioception, most of us can close our eyes and touch the tip of our index finger to our nose. Thanks to our vestibular sense, we typically have a good idea of which way is up and can maintain balance. It may be tempting to give a new name to each inability to have a given type of imagined sensation. But this could lead to confusion. Another approach would be to adapt phrases that are already widely used. People who are unable to have imagined sensations commonly refer to ourselves as “aphants”. This could be adapted with a prefix, such as “audio aphant”. Time will tell which approach is adopted by most researchers. <h2>Why we should keep investigating</h2> Regardless of the names we use, the study of multiple types of inability to have an imagined sensation is important. These investigations could reveal the essential processes in human brains that bring about a conscious experience of an imagined sensation. In time, this will not only lead to a better understanding of the diversity of humans, but may help uncover how human brains can create any conscious sensation. This question – how and where our conscious feelings are generated – remains one of the great mysteries of science.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/230973/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/derek-arnold-106381">Derek Arnold</a>, Professor, School of Psychology, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Want to reduce your dementia risk? Eat these 4 foods, says new study

If you are what you eat, this might make you hungrier for foods that are bright in every sense. Research has shown that living, vibrant foods can slow down aging at a cellular level; while fruit and vegetables in particular have been associated with lower incidence of cognitive decline as individuals age. However, research has been relatively lacking on just how much of these brain-healthy foods you really need and which fruit and vegetables are best for the job. In collaboration with public health experts at Harvard University, medical researchers at China’s Zhejiang University School of Medicine conducted a meta-analysis that’s slated to be published in the June 2024 issue of The Journal of Nutrition, Health, and Aging. They combined data from two large-scale population-representative studies that analysed the diets and cognitive function of more than 10,000 participants ages 55 and older from China and the US. <h2>What daily diets revealed</h2> The data included diet questionnaires that honed in on the average of participants’ total daily intake of several different types of foods, including fruit and vegetables, and also broke them down into sub-types like green leafy vegetables and berries. Over a period of five years, the participants also took part in activities designed to assess their cognitive function and the average rate of cognitive decline. Overall, participants who included the most fruit and vegetables in their daily diets performed best on the brain tests and maintained those results over time. This suggested that both fruit and vegetables had protective elements that slowed cognitive decline. <h2>Vegetables that help protect cognition</h2> Interestingly, certain types of vegetables appeared to be more beneficial than others—say the researchers: “Our findings support the potential beneficial roles of VF, especially cruciferous vegetables, green leafy vegetables, and red and yellow vegetables, in maintaining cognitive function and slowing cognitive decline in middle-aged and older adults.” The researchers pointed to several reasons these particular vegetables might have shown a substantial impact, including anti-inflammatory and antioxidation nutrients like flavonoids and various vitamins or even gut improvements that have been shown to help improve or protect cognition. While beans didn’t figure prominently in both studies, they showed a protective element in the US study, so they are also worth keeping on your plate. (Beans are also thought to be one of the top foods for longevity.) <h2>Fruit that pack a punch</h2> As for fruit, while some didn’t show as much of a protective effect across the board, berries and apples are two examples of fruit that experts have previously said provide major polyphenol and antioxidant effect. Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.

Queen Mary’s wedding dressmaker reveals process behind iconic gown

The Danish designer and dressmaker who designed Queen Mary’s wedding gown has recalled the “rather terrifying” process of making the iconic dress. Birgit Hallstein created the custom gown for the Aussie-born royal for her to marry Prince Frederik in 2004, as the designer recalled having to adhere to an unusual royal tradition when creating the dress. Hallstein said that she put the finishing touches on the dress on the wedding day: a decision that was mentioned to her by Mary's new mother-in-law, Queen Margrethe. Hallstein admits the old tradition, which involves doing the final loops and stitches the morning of the wedding, also helped her process in the long run. "[It] was a thing I did because it's a tradition in some families, but honestly I don't remember if Queen Margrethe would have mentioned such a thing," Hallstein told <a href="https://style.nine.com.au/latest/queen-mary-of-denmark-20th-wedding-anniversary-wedding-dressmaker-birgit-hallstein-interview/9f0c57eb-2d7b-44fd-ae0b-487d1b3592a5">9Honey</a>. "Maybe, because she knows a lot of those things... I am sure we talked about it, but anyway it was practical to gather the dress on the day because it's big." The process for Hallstein began in November 2003, as she admitted it was the most important garment she had ever worked on. "It was rather terrifying," she admitted with a laugh. "It's a bit like an exam, just a really big one, because if you fail everyone will see." Hallstein worked in a dedicated space at Amalienborg Palace to deliver the gown as well as the outfits worn by the bridesmaids, page boys and flower girls. "The sewing took hundreds of hours, starting in January 2004 and ending right before the wedding," she recalled. There was also the added pressure of adhering to royal traditions and protocols around the use of the antique veil and the lace attachment to the petticoat, which was from Queen Margrethe's private collection. "There are rules to follow, [you're] not allowed to cut in it and only skilled repairs [are allowed]," Hallstein said. "I had to hide around two or three metres of the antique lace in between layers of organza inside the dress to make sure it was not damaged by high heels, chairs, cars and carriages during the day." In a social media post to mark 20 years since the world got their first look at the classic gown, the dressmaker explained to fans that "the wedding gown consists of three parts". “There's a big tulle petticoat, edged with almost 60 yards of Chantilly lace, on this a big light blue silk bow were placed, to make sure the first born would be a son," she said.

4 foods that ease heartburn

Heartburn, acid reflux, GORD… whatever you want to call it, it’s not a pleasant thing to experience. Yet hundreds of thousands of us around the country suffer from heartburn each year. And while medication may be the solution for some, it’s not always the most effective option. So, you’ll be happy to learn that what you eat may ease your symptoms. Here are four of the best foods for heartburn. 1. Papaya Papain, an enzyme found in papaya, has been proven to aid in digestion. In addition, the fibre content and proteolytic enzymes are a great source of short-chain fatty acids, which <a href="https://www.ideals.illinois.edu/handle/2142/29416" target="_blank" rel="noopener">a recent study</a> described as “the most important product of fermentation”, and an essential part of improving gut health. 2. Aloe vera juice Aloe vera does much more than just ease sunburn or skin irritations – it’s been used to help ease constipation and treat type 2 diabetes and gastrointestinal disorders for centuries. “Its anti-inflammatory properties have been suggested to ease inflammation in the oesophagus caused by reflux,” Maria Bella, author of The Complete Idiot’s Guide to the Acid Reflux Diet, tells <a href="http://www.goodhousekeeping.com/health/diet-nutrition/g4536/best-foods-for-acid-reflux/" target="_blank" rel="noopener">Good Housekeeping</a>. 3. Banana Because of its low acidity, bananas are great for gastrointestinal discomfort, but they’re particularly good for heartburn as they can stick to the irritated oesophageal lining. “It forms a protective film that coats, protects and soothes,” digestive health expert Dr Gerard E. Mullin explains to <a href="http://www.prevention.com/food/foods-soothe-heartburn" target="_blank" rel="noopener">Prevention</a>. 4. Cinnamon gum By producing saliva, gum helps neutralise stomach acid. “It also leads to more frequent swallowing, which can move the irritating acid down the oesophagus more quickly,” Maria Bella says. Mint can make your symptoms worse, however, so stick to cinnamon, which <a href="http://www.ncbi.nlm.nih.gov/pubmed/20924865" target="_blank" rel="noopener">studies show</a> may have anti-inflammatory properties.

Not all ultra-processed foods are bad for your health, whatever you might have heard

But new evidence published <a href="https://www.bmj.com/content/385/bmj-2023-078476">this week</a> found not all “ultra-processed” foods are linked to poor health. That includes the mass-produced wholegrain bread you buy from the supermarket. While this newly published research and associated <a href="https://www.bmj.com/content/385/bmj.q793">editorial</a> are unlikely to end the wrangling about how best to define unhealthy foods and diets, it’s critical those debates don’t delay the implementation of policies that are likely to actually improve our diets. <h2>What are ultra-processed foods?</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">Ultra-processed foods</a> are industrially produced using a variety of processing techniques. They typically include ingredients that can’t be found in a home kitchen, such as preservatives, emulsifiers, sweeteners and/or artificial colours. Common examples of ultra-processed foods include packaged chips, flavoured yoghurts, soft drinks, sausages and mass-produced packaged wholegrain bread. In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7719194/#CR13">many other countries</a>, ultra-processed foods make up a large proportion of what people eat. A <a href="https://pubmed.ncbi.nlm.nih.gov/31676952/">recent study</a> estimated they make up an average of 42% of total energy intake in Australia. <h2>How do ultra-processed foods affect our health?</h2> Previous <a href="https://pubmed.ncbi.nlm.nih.gov/33167080/">studies</a> have linked increased consumption of ultra-processed food with poorer health. High consumption of ultra-processed food, for example, has been associated with a <a href="https://pubmed.ncbi.nlm.nih.gov/38418082/">higher risk</a> of type 2 diabetes, and death from heart disease and stroke. Ultra-processed foods are typically high in energy, added sugars, salt and/or unhealthy fats. These have long been <a href="https://www.who.int/news-room/fact-sheets/detail/healthy-diet">recognised</a> as risk factors for a range of diseases. It has also been suggested that structural changes that happen to ultra-processed foods as part of the manufacturing process <a href="https://pubmed.ncbi.nlm.nih.gov/31105044/">may</a> lead you to eat more than you should. Potential explanations are that, due to the way they’re made, the foods are quicker to eat and more palatable. It’s also <a href="https://pubmed.ncbi.nlm.nih.gov/35952706/">possible</a> certain food additives may impair normal body functions, such as the way our cells reproduce. <h2>Is it harmful? It depends on the food’s nutrients</h2> The <a href="https://www.bmj.com/content/385/bmj-2023-078476">new paper</a> just published used 30 years of data from two large US cohort studies to evaluate the relationship between ultra-processed food consumption and long-term health. The study tried to disentangle the effects of the manufacturing process itself from the nutrient profile of foods. The study found a small increase in the risk of early death with higher ultra-processed food consumption. But importantly, the authors also looked at diet quality. They found that for people who had high quality diets (high in fruit, vegetables, wholegrains, as well as healthy fats, and low in sugary drinks, salt, and red and processed meat), there was no clear association between the amount of ultra-processed food they ate and risk of premature death. This suggests overall diet quality has a stronger influence on long-term health than ultra-processed food consumption. When the researchers analysed ultra-processed foods by sub-category, mass-produced wholegrain products, such as supermarket wholegrain breads and wholegrain breakfast cereals, were not associated with poorer health. This finding matches another recent <a href="https://pubmed.ncbi.nlm.nih.gov/38417577/">study</a> that suggests ultra-processed wholegrain foods are not a driver of poor health. The authors concluded, while there was some support for limiting consumption of certain types of ultra-processed food for long-term health, not all ultra-processed food products should be universally restricted. <h2>Should dietary guidelines advise against ultra-processed foods?</h2> Existing national <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55_australian_dietary_guidelines.pdf">dietary</a> <a href="https://www.health.govt.nz/system/files/documents/publications/eating-activity-guidelines-new-zealand-adults-updated-2020-oct22.pdf">guidelines</a> have been developed and refined based on decades of nutrition evidence. Much of the recent evidence related to ultra-processed foods tells us what we already knew: that products like soft drinks, alcohol and processed meats are bad for health. Dietary guidelines <a href="https://pubmed.ncbi.nlm.nih.gov/35184508/">generally</a> already advise to eat mostly whole foods and to limit consumption of highly processed foods that are high in refined grains, saturated fat, sugar and salt. But some nutrition researchers have <a href="https://www.bmj.com/content/384/bmj.q439">called</a> for dietary guidelines to be amended to recommend avoiding ultra-processed foods. Based on the available evidence, it would be difficult to justify adding a sweeping statement about avoiding all ultra-processed foods. Advice to avoid all ultra-processed foods would likely unfairly impact people on low-incomes, as many ultra-processed foods, such as supermarket breads, are relatively affordable and convenient. Wholegrain breads also provide important nutrients, such as fibre. In many countries, bread is the <a href="https://www.health.govt.nz/system/files/documents/publications/a-focus-on-nutrition-ch3_0.pdf">biggest contributor</a> to fibre intake. So it would be problematic to recommend avoiding supermarket wholegrain bread just because it’s ultra-processed. <h2>So how can we improve our diets?</h2> There is strong <a href="https://www.foodpolicyindex.org.au/_files/ugd/7ee332_a2fa1694e42f423195caf581044fccf1.pdf">consensus</a> on the need to implement evidence-based policies to improve population diets. This includes legislation to restrict children’s exposure to the marketing of unhealthy foods and brands, mandatory Health Star Rating nutrition labelling and taxes on sugary drinks. These policies are underpinned by <a href="https://pubmed.ncbi.nlm.nih.gov/37659696/">well-established systems</a> for classifying the healthiness of foods. If new evidence unfolds about mechanisms by which ultra-processed foods drive health harms, these classification systems can be updated to reflect such evidence. If specific additives are found to be harmful to health, for example, this evidence can be incorporated into existing nutrient profiling systems, such as the <a href="http://www.healthstarrating.gov.au/internet/healthstarrating/publishing.nsf/content/home">Health Star Rating</a> food labelling scheme. Accordingly, policymakers can confidently progress food policy implementation using the tools for classifying the healthiness of foods that we already have. Unhealthy diets and obesity are among the <a href="https://www.aihw.gov.au/reports/burden-of-disease/burden-of-disease-study-2018-key-findings/contents/key-findings">largest contributors</a> to poor health. We can’t let the hype and academic debate around “ultra-processed” foods delay implementation of globally recommended policies for improving population diets.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229493/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gary-sacks-3957">Gary Sacks</a>, Professor of Public Health Policy, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-backholer-10739">Kathryn Backholer</a>, Co-Director, Global Centre for Preventive Health and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-bradbury-1532662">Kathryn Bradbury</a>, Senior Research Fellow in the School of Population Health, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a>, and <a href="https://theconversation.com/profiles/sally-mackay-1532685">Sally Mackay</a>, Senior Lecturer Epidemiology and Biostatistics, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Yes, adults can develop food allergies. Here are 4 types you need to know about

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> If you didn’t have food allergies as a child, is it possible to develop them as an adult? The short answer is yes. But the reasons why are much more complicated. Preschoolers are about <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">four times more likely to have a food allergy</a> than adults and are more likely to grow out of it as they get older. It’s hard to get accurate figures on adult food allergy prevalence. The Australian National Allergy Council reports <a href="https://nationalallergycouncil.org.au/about-us/our-strategy">one in 50 adults</a> have food allergies. But a US survey suggested as many as <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">one in ten adults</a> were allergic to at least one food, with some developing allergies in adulthood. <h2>What is a food allergy</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">Food allergies</a> are immune reactions involving <a href="https://www.aaaai.org/tools-for-the-public/allergy,-asthma-immunology-glossary/immunoglobulin-e-(ige)-defined">immunoglobulin E (IgE)</a> – an antibody that’s central to triggering allergic responses. These are known as “IgE-mediated food allergies”. Food allergy symptoms that are not mediated by IgE are usually delayed reactions and called <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">food intolerances or hypersensitivity</a>. Food allergy symptoms can include hives, swelling, difficulty swallowing, vomiting, throat or chest tightening, trouble breathing, chest pain, rapid heart rate, dizziness, low blood pressure or <a href="https://www.allergy.org.au/hp/papers/acute-management-of-anaphylaxis-guidelines?highlight=WyJhbmFwaHlsYXhpcyJd">anaphylaxis</a>. IgE-mediated food allergies can be life threatening, so all adults need an <a href="https://allergyfacts.org.au/allergy-management/newly-diagnosed/action-plan-essentials">action management plan</a> developed in consultation with their medical team. Here are four IgE-mediated food allergies that can occur in adults – from relatively common ones to rare allergies you’ve probably never heard of. <h2>1. Single food allergies</h2> The most <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">common IgE-mediated food allergies</a> in adults in a US survey were to: <ul> <li>shellfish (2.9%)</li> <li>cow’s milk (1.9%)</li> <li>peanut (1.8%)</li> <li>tree nuts (1.2%)</li> <li>fin fish (0.9%) like barramundi, snapper, salmon, cod and perch.</li> </ul> In these adults, about 45% reported reacting to multiple foods. This compares to <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">most common childhood food allergies</a>: cow’s milk, egg, peanut and soy. Overall, adult food allergy prevalence appears to be increasing. Compared to <a href="https://pubmed.ncbi.nlm.nih.gov/14657884/">older surveys published in 2003</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15241360/">2004</a>, peanut allergy prevalence has increased about three-fold (from 0.6%), while tree nuts and fin fish roughly doubled (from 0.5% each), with shellfish similar (2.5%). While new <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">adult-onset food allergies are increasing</a>, childhood-onset food allergies are also more likely to be retained into adulthood. Possible reasons for both <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">include</a> low vitamin D status, lack of immune system challenges due to being overly “clean”, heightened sensitisation due to allergen avoidance, and more frequent antibiotic use. <h2>2. Tick-meat allergy</h2> Tick-meat allergy, also called α-Gal syndrome or mammalian meat allergy, is an allergic reaction to galactose-alpha-1,3-galactose, or α-Gal for short. <a href="https://pubmed.ncbi.nlm.nih.gov/33529984/">Australian immunologists first reported</a> links between α-Gal syndrome and tick bites in 2009, with cases also reported in the United States, Japan, Europe and South Africa. The <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">US Centers for Disease Control estimates</a> about 450,000 Americans <a href="https://www.cdc.gov/mmwr/volumes/72/wr/mm7230a2.htm">could be affected</a>. The α-Gal contains a carbohydrate molecule that is bound to a <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">protein</a> molecule in <a href="https://alphagalinformation.org/what-is-a-mammal/">mammals</a>. The IgE-mediated allergy is triggered after repeated bites from ticks or <a href="https://www.insectshield.com/pages/chiggers">chigger mites</a> that have bitten those mammals. When tick saliva crosses into your body through the bite, antibodies to α-Gal are produced. When you subsequently eat foods that contain α-Gal, the allergy is triggered. These triggering foods include meat (lamb, beef, pork, rabbit, kangaroo), dairy products (yoghurt, cheese, ice-cream, cream), <a href="https://en.wikipedia.org/wiki/Gelatin">animal-origin gelatin</a> added to gummy foods (jelly, lollies, marshmallow), prescription medications and over-the counter supplements containing gelatin (<a href="https://www.drugs.com/inactive/gelatin-57.html">some antibiotics, vitamins and other supplements</a>). Tick-meat allergy reactions can be hard to recognise because they’re usually delayed, and they can be severe and include anaphylaxis. Allergy <a href="https://www.allergy.org.au/patients/food-allergy/mammalian-meat-tick-faq">organisations produce management guidelines</a>, so always discuss management with your doctor. <h2>3. Fruit-pollen allergy</h2> Fruit-pollen allergy, called pollen food allergy syndrome, is an <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">IgE-mediated allergic reaction</a>. In susceptible adults, pollen in the air provokes the production of IgE antibodies to antigens in the pollen, but these antigens are similar to ones found in some fruits, vegetables and herbs. The problem is that <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">eating those plants</a> triggers an allergic reaction. The <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">most allergenic tree pollens</a> are from birch, cypress, Japanese cedar, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/latex-allergy">latex</a>, grass, and ragweed. Their pollen can cross-react with <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">fruit and vegetables</a>, including kiwi, banana, mango, avocado, grapes, celery, carrot and potato, and some herbs such as caraway, coriander, fennel, pepper and paprika. Fruit-pollen allergy is not common. Prevalence <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">estimates are between 0.03% and 8%</a> depending on the country, but it can be life-threatening. Reactions range from itching or tingling of lips, mouth, tongue and throat, called <a href="https://pubmed.ncbi.nlm.nih.gov/20306812/">oral allergy syndrome</a>, to mild <a href="https://www.allergy.org.au/patients/skin-allergy/urticaria-hives">hives</a>, to anaphylaxis. <h2>4. Food-dependent, exercise-induced food allergy</h2> During heavy exercise, the stomach produces less acid than usual and gut permeability increases, meaning that small molecules in your gut are more likely to escape across the membrane into your blood. These include food molecules that trigger an IgE reaction. If the person already has IgE antibodies to the foods eaten before exercise, then the risk of triggering food allergy reactions is increased. This allergy is called <a href="https://pubmed.ncbi.nlm.nih.gov/37893663/">food-dependent exercise-induced allergy</a>, with symptoms ranging from hives and swelling, to difficulty breathing and anaphylaxis. <a href="https://pubmed.ncbi.nlm.nih.gov/30601082/">Common trigger foods include</a> wheat, seafood, meat, poultry, egg, milk, nuts, grapes, celery and other foods, which could have been eaten many hours before exercising. To complicate things even further, allergic <a href="https://pubmed.ncbi.nlm.nih.gov/33181008/">reactions can</a> occur at lower levels of trigger-food exposure, and be more severe if the person is simultaneously taking non-steroidal inflammatory medications like aspirin, drinking alcohol or is sleep-deprived. Food-dependent exercise-induced allergy is extremely rare. Surveys have estimated prevalence as between <a href="https://www.sciencedirect.com/science/article/pii/S1555415517300259">one to 17 cases per 1,000 people worldwide</a> with the highest prevalence between the teenage years to age 35. Those affected often have other allergic conditions such as hay fever, asthma, allergic conjunctivitis and dermatitis. <h2>Allergies are a growing burden</h2> The <a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">burden on physical health, psychological health</a> and health costs due to food allergy is increasing. In the US, this <a href="https://pubmed.ncbi.nlm.nih.gov/38393624/">financial burden was estimated as $24 billion per year</a>. Adult food allergy needs to be taken seriously and those with severe symptoms should wear a medical information bracelet or chain and carry an <a href="https://www.healthdirect.gov.au/how-to-use-an-adrenaline-autoinjector-epipen-anapen">adrenaline auto-injector pen</a>. Concerningly, surveys suggest only <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">about one in four adults</a> with food allergy have an adrenaline pen. If you have an IgE-mediated food allergy, discuss your management plan with your doctor.

Sydneysiders witnessed horrific scenes on Saturday. How do you process and recover from such an event?

<a href="https://theconversation.com/profiles/kim-felmingham-9075">Kim Felmingham</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Like many, I watched the reports of the violent attack at Bondi Junction yesterday with shock, horror and disbelief. My heart goes out to the people involved, the courageous first responders and to those who have lost loved ones in this tragic event. I also feel for those who witnessed the horror and will be working out how to get through the initial shock and, over time, put it behind them. Distress and strong emotional reactions are <a href="https://kclpure.kcl.ac.uk/portal/en/publications/the-psychological-and-psychiatric-effects-of-terrorism-lessons-fr">common</a> after these types of mass violent events. But different people will have <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">different emotional reactions</a> – and some may experience a range of shifting emotions. <h2>The first few days and weeks</h2> In the days and weeks after traumatic events like these, people <a href="https://www.ptsd.va.gov/understand/isitptsd/common_reactions.asp#:%7E:text=All%20kinds%20of%20trauma%20create,stop%20thinking%20about%20what%20happened.">often experience</a> a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306457320308670">range of emotions</a>: from fear and anxiety, anger, sadness and grief, disbelief and numbness, guilt and worry about safety. They may be jittery, more irritable or on edge, or it may affect their sleep. For many, their sense of risk may be heightened, particularly as such random violence occurred during such an ordinary event – shopping on a Saturday afternoon. This <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">can lead to</a> a heightened awareness of danger and concern for safety. <h2>What’s likely to happen over time?</h2> For most people, as they begin to process and make sense of what happened, these feelings will gradually reduce in intensity and people will begin to recover. <a href="https://pubmed.ncbi.nlm.nih.gov/25311288/">Research shows</a> the majority of people recover from mass violent events within the initial few months. However, for people with more direct exposure to the trauma, these events and reactions may be more difficult to process. Some people <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">may go on</a> to develop mental health difficulties, most commonly anxiety, depression and post-traumatic stress disorder (PTSD). Understandably, those <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">more at risk</a> are people who were present during the trauma and experienced a direct threat, as well as those who witnessed the violence or aftermath, first responders (paramedics and police) and those who had loved ones injured or lost during the event. People who had more intense emotional responses during the trauma, or previous psychological difficulties or traumatic experiences, may also be <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">at greater risk</a>. <h2>What helps – and hinders – your recovery?</h2> To help process these traumatic events and promote recovery, social support is <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">particularly important</a>. Spending time with trusted family and friends can help people process the events and their emotional reactions. Talking about your feelings with supportive people can help you understand and accept them. But even if you don’t want to talk about your feelings, spending time with loved ones is helpful. It is also fine to need some time to be alone, but try not to isolate yourself or withdraw. If you can’t talk about your feelings, try not to bottle them up or deal with them by using alcohol or drugs. Find <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7957853/">another way to express them</a> – whether through writing, art or music, or exercise. Give yourself permission and time to feel these emotions. Remind yourself you have just been through something extremely traumatic, take things day by day, and don’t expect too much of yourself. Try not to judge yourself for your actions or how you are coping. Keep some structure in your day, setting small goals, and increase your self-care: eat well, rest (even if you can’t sleep well), try yoga or relaxation. When you’re ready, try to get back to your normal routine. Seek out information from <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7957853/">trusted sources</a>, but try to <a href="https://journals.sagepub.com/doi/10.1177/0886260517742915">avoid</a> being saturated by images or stories about the trauma, particularly graphic footage or speculation common on social media. <h2>What if children have witnessed it, too?</h2> If your children have been impacted, reassure them that they are safe and loved. When they are ready, talk to them gently about the trauma, acknowledge it and answer their questions. Encourage them to express their feelings and spend more time together doing family activities. Importantly, try to limit their exposure to graphic footage and images of the events in the media, and on social media. <h2>When to seek mental health care</h2> Reach out for professional mental health support if you experience ongoing difficulty with your emotional reactions, or if you’re having distressing memories of the trauma, difficulty sleeping or nightmares, or you want to avoid things that remind you of the traumatic event. Not everyone requires professional mental health support, but if you are experiencing these types of post-traumatic stress reactions a few weeks after the trauma, it’s important to speak to your GP to seek out professional support from psychologists or counselling services.

How bad is junk food for you, really?

<div> Consuming more junk foods, such as soft drinks, packaged snacks, and sugary cereals, is associated with a higher risk of more than 30 different health problems – both physical and mental – according to researchers. A study, known as an umbrella review, combined the results of 45 previous meta-analyses published in the last three years, representing about 10 million participants. Thirty-two different poor health outcomes were found to be linked to the consumption of ultra-processed foods (UPFs), with varying levels of evidence supporting the findings. The researchers found the most convincing evidence around higher ultra-processed food intake, which was associated with a 50% increased risk of cardiovascular disease-related death, a 48-53% higher risk of anxiety and common mental disorders, and a 12% greater risk of type 2 diabetes. Evidence marked as ‘highly suggestive’ included a 21% increase in death from any cause, a 40-66% increased risk of a heart disease related death, obesity, type 2 diabetes, and sleep problems, as well as a 22% increased risk of depression. The review also found there may be links between ultra-processed food and asthma; gastrointestinal health; some cancers; and other risk factors such as high blood fats and low levels of ‘good’ cholesterol, but the researchers note this evidence is limited. Dr Daisy Coyle from the George Institute for Global Health in Sydney, who was not involved in the research, says the statistics are “staggering.” “Ultra-processed foods, laden with additives and sometimes lacking in essential nutrients, have become ubiquitous in the Australian diet,” she says. “In fact, they make up almost half of what we buy at the supermarket. While not all ultra-processed foods are linked to poor health outcomes, many are, particularly sugary drinks and processed meats.” <div> </div> While the findings are in line with other research that highlights the health risks associated with UPFs, some experts have pointed out that the study is observational, and therefore can’t prove the ultra-processed foods cause these health issues. It can only show an association. “While these associations are interesting and warrant further high-quality research, they do not and cannot provide evidence of causality,” The University of Sydney’s Dr Alan Barclay told the AusSMC. “By their very nature, observational studies are renowned for being confounded by numerous factors – both known and unknown.” Clare Collins, Laureate Professor at the University of Newcastle agreed, but added that it’s difficult to conduct dietary studies like this in a different way. “The studies are observational, which means cause and effect cannot be proven and that the research evidence gets downgraded, compared to intervention studies,” she says. “The problem is that it is not ethical to do an intervention study lasting for many years where you feed people lots of UPF every day and wait for them to get sick and die.” For now, researchers seem to agree that it can’t be a bad thing to minimise UPF intake. The review suggests a need for policies that pull consumers away from ultra-processed foods, such as advertising restrictions, warning labels, bans in schools and hospitals. It also calls for measures that make healthier foods more accessible and affordable. Dr Charlotte Gupta from Central Queensland University suggests that this is issue of accessibility is particularly relevant for shift workers such as doctors, nurses, firefighters, taxi drivers, miners, and hospitality workers. “There is a lack of availability of fresh foods or time to prepare any food, and so ultra-processed foods have to be relied on (e.g. from the vending machine in the hospital),” she said. “This highlights the need for not only individuals to try reducing ultra-processed foods in our diet, but also for public health actions to improve access to healthier foods.” Image credits: Shutterstock <a href="https://cosmosmagazine.com/health/how-bad-is-junk-food-for-you-really/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/olivia-henry/">Olivia Henry</a>. </div>

Why is gluten-free bread so expensive? A food supply chain expert explains

<a href="https://theconversation.com/profiles/flavio-macau-998456">Flavio Macau</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Before the cost of living hit Australian families hard, a group of consumers were already paying top dollar for their staples. Whether it be gluten free, dairy free or lactose free, people with special dietary requirements are used to spending more at the supermarket checkout. A 2016 study from the University of Wollongong found that Australians were <a href="https://onlinelibrary.wiley.com/doi/10.1111/1747-0080.12171">paying up to 17% more for a gluten-free diet</a>. Current examples are easy to find. A <a href="https://www.coles.com.au/product/coles-white-bread-650g-4901345">white sandwich loaf at Coles</a> costs A$2.40 (or A$0.37 per 100g), whereas <a href="https://www.coles.com.au/product/coles-i'm-free-from-white-loaf-500g-3216673">the cheapest gluten-free option</a> costs $5.70 (or $1.14 per 100g). That’s over three times as much. Prices are closer comparing Coles Full Cream Milk at A$1.50 per litre with Coles Lactose Free Lite Milk at A$1.60, the exception that confirms the rule. So why are allergen-free products more expensive? <h2>Is it the ingredients?</h2> If manufacturers pay more for ingredients, this is usually reflected in the price of the final product. Regular and gluten-free bread share many common ingredients, but there is a substantial change where wheat flour is replaced by gluten-free flour. This ingredient may cost manufacturers around two times as much given the uniqueness of gluten-free grains, seeds, and nuts. These special ingredients are not as abundant or easy to process as wheat, and are also a bit more difficult to buy in very large scale. For a simple reference, compare <a href="https://www.coles.com.au/product/coles-white-plain-flour-1kg-5881232">regular</a> and <a href="https://www.coles.com.au/product/coles-i'm-free-from-plain-flour-gluten-free-500g-2478197">gluten-free flour</a> at Coles. Gluten, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jgh.13703">a complex mixture of hundreds of related but distinct proteins</a>, has unique properties. It is a binding agent that improves texture in recipes. Gluten-free bread therefore needs extra help to, literally, hold it together. Additional items such as thickeners, tapioca and maize starches are added to gluten-free recipes to improve viscosity and keep baked items in shape. That means a longer ingredient list and a slightly more complex manufacturing process. So, from an ingredient perspective, gluten-free bread costs more than regular bread. This applies for other allergen-free products as well. But with so many common ingredients, it is reasonable to say that this is not the main explanation. <h2>Is it manufacturing and transporting?</h2> A substantial part of price differences between regular and allergen-free foods comes from <a href="https://www.investopedia.com/terms/e/economiesofscale.asp">economies of scale</a>. Regular products are manufactured in very large quantities, while allergen-free products involve much smaller volumes. Bulk buying from large suppliers gets you bigger discounts. The more machines in a factory, the cheaper it is to run them. Larger outputs coming from the same place mean smaller costs for each individual product. Given that you have fixed costs to pay anyway, size is king. You pay the same amount for a grain mill regardless of whether you grind one kilo or one tonne of grains a day. Sure, you spend more on electricity or gas, but those are <a href="https://corporatefinanceinstitute.com/resources/accounting/fixed-and-variable-costs/">variable costs</a>. Then, there is the need for rigorous quality control. The United Nations Food and Agriculture Organization has a detailed <a href="https://www.fao.org/fao-who-codexalimentarius/sh-proxy/en/?lnk=1&url=https%253A%252F%252Fworkspace.fao.org%252Fsites%252Fcodex%252FStandards%252FCXC%2B80-2020%252FCXC_080e.pdf">code of practice on food allergen management for food business operators</a>, covering harvesting, handling, storage, transportation, packaging, and more. The <a href="https://www.foodstandards.gov.au/food-standards-code">Australia New Zealand Food Standards Code</a> also sets specific standards. Deep cleaning machines, thoroughly checking that standards are met, and scrapping whole batches when they are not makes manufacturing allergen-free products more complex and expensive. The <a href="https://www.health.wa.gov.au/-/media/Files/Corporate/general-documents/food/PDF/DOHComplianceandEnforcementPolicyVersion3.pdf">implications for non-compliance</a> vary in severity, from a simple recall to a costly infringement notice, plus <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10574315/">reputational damage to consumer trust</a>. It is hard to exactly measure the impact of economies of scale and quality costs on the price of allergen-free products. Each manufacturer will have its own challenges and solutions. But it is reasonable to say a considerable chunk of the difference we see when comparing gluten-free bread with its regular counterpart comes from these factors. Transportation costs follow a similar rule. If it is easier and quicker to fill your trucks with regular products, while allergen-free products have a hard time making a full load, there are disadvantages in the latter. <h2>Is it the marketing strategy?</h2> The final consideration on allergen-free food prices has to do with competition and willingness to pay. A quick search on Coles’ website shows 276 results for “bread” once you remove the 42 items that are gluten-free. That means that there are many more brands and products competing for bread consumers than for gluten-free bread consumers. That’s over six to one! This means customers with dietary restrictions are at a disadvantage as they are beholden to the limited options on offer. As noted by the Australian Competition & Consumer Commission, “<a href="https://www.accc.gov.au/business/competition-and-exemptions/competition-and-anti-competitive-behaviour">competition leads to lower prices and more choice for consumers</a>”. Also, fewer allergen-free products make it to the “own brand” list. Australians are <a href="https://www.news.com.au/finance/money/costs/coles-woolworths-ownbrand-products-booming-on-back-of-costofliving-crisis/news-story/d0be8b8d6e98c0a6477959cd83da17ad">relying more on these when facing the cost-of-living crisis</a>. There is also the <a href="https://online.hbs.edu/blog/post/willingness-to-pay">willingness to pay</a>, where consumers pay more for products deemed as having higher value. <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/obr.13525">Research</a> shows that on average consumers are willing to pay 30% more for food products that they perceive to be healthier. Manufacturers and retailers more often than not will capitalise on that, increasing their profit margins for allergen-free products. <h2>4 tips for saving money if you have allergies</h2> People with dietary requirements looking to ease the cost of their weekly grocery shop should use the same strategies as every savvy consumer: <ul> <li>research prices</li> <li>buy larger quantities where possible</li> <li>keep a keen eye on price reduction and items on sale</li> <li>consider replacing products tagged “allergen-free” with alternatives from other categories, such as going for rice instead of gluten-free pasta in a dish.</li> </ul> In the long run, if more customers choose allergen-free products it could lead to more volume and competition, bringing prices down. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223648/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/flavio-macau-998456">Flavio Macau</a>, Associate Dean - School of Business and Law, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Money & Banking

We looked at 700 plant-based foods to see how healthy they really are. Here’s what we found

<a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> If you’re thinking about buying plant-based foods, a trip to the supermarket can leave you bewildered. There are plant-based burgers, sausages and mince. The fridges are loaded with non-dairy milk, cheese and yoghurt. Then there are the tins of beans and packets of tofu. But how much is actually healthy? Our nutritional audit of more than 700 plant-based foods for sale in Australian supermarkets has just been <a href="https://www.sciencedirect.com/science/article/pii/S0889157524000516">published</a>. We found some products are so high in salt or saturated fat, we’d struggle to call them “healthy”. <h2>We took (several) trips to the supermarket</h2> In 2022, we visited two of each of four major supermarket retailers across Melbourne to collect information on the available range of plant-based alternatives to meat and dairy products. We took pictures of the products and their nutrition labels. We then analysed the nutrition information on the packaging of more than 700 of these products. This included 236 meat substitutes, 169 legumes and pulses, 50 baked beans, 157 dairy milk substitutes, 52 cheese substitutes and 40 non-dairy yoghurts. <h2>Plant-based meats were surprisingly salty</h2> We found a wide range of plant-based meats for sale. So, it’s not surprising we found large variations in their nutrition content. Sodium, found in added salt and which contributes to <a href="https://www.heartfoundation.org.au/bundles/healthy-living-and-eating/salt-and-heart-health">high blood pressure</a>, was our greatest concern. The sodium content varied from 1 milligram per 100 grams in products such as tofu, to 2,000mg per 100g in items such as plant-based mince products. This means we could eat our entire <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/salt">daily recommended sodium intake</a> in just one bowl of plant-based mince. An <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">audit</a> of 66 plant-based meat products in Australian supermarkets conducted in 2014 found sodium ranged from 316mg in legume-based products to 640mg in tofu products, per 100g. In a <a href="https://www.mdpi.com/2072-6643/11/11/2603">2019 audit</a> of 137 products, the range was up to 1,200mg per 100g. In other words, the results of our audit seems to show a consistent trend of plant-based meats <a href="https://www.tandfonline.com/doi/full/10.1080/09637486.2022.2137786">getting saltier</a>. <h2>What about plant-based milks?</h2> Some 70% of the plant-based milks we audited were fortified with calcium, a nutrient important for <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/calcium">bone health</a>. This is good news as a <a href="https://www.mdpi.com/2072-6643/12/5/1254">2019-2020 audit</a> of 115 plant-based milks from Melbourne and Sydney found only 43% of plant-based milks were fortified with calcium. Of the fortified milks in our audit, almost three-quarters (73%) contained the <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/milk-yoghurt-cheese-andor-their-alternatives-mostly-reduced-fat">recommended amount of calcium</a> – at least 100mg per 100mL. We also looked at the saturated fat content of plant-based milks. Coconut-based milks had on average up to six times higher saturated fat content than almond, oat or soy milks. <a href="https://www.mdpi.com/2072-6643/12/5/1254">Previous audits</a> also found coconut-based milks were much higher in saturated fat than all other categories of milks. <h2>A first look at cheese and yoghurt alternatives</h2> Our audit is the first study to identify the range of cheese and yoghurt alternatives available in Australian supermarkets. Calcium was only labelled on a third of plant-based yoghurts, and only 20% of supermarket options met the recommended 100mg of calcium per 100g. For plant-based cheeses, most (92%) were not fortified with calcium. Their sodium content varied from 390mg to 1,400mg per 100g, and saturated fat ranged from 0g to 28g per 100g. <h2>So, what should we consider when shopping?</h2> As a general principle, try to choose whole plant foods, such as unprocessed legumes, beans or tofu. These foods are packed with vitamins and minerals. They’re also high in dietary fibre, which is good for your gut health and keeps you fuller for longer. If opting for a processed plant-based food, here are five tips for choosing a healthier option. 1. Watch the sodium Plant-based meat alternatives can be high in sodium, so look for products that have <a href="https://www.eatforhealth.gov.au/eating-well/how-understand-food-labels/food-labels-what-look">around</a> 150-250mg sodium per 100g. 2. Pick canned beans and legumes Canned chickpeas, lentils and beans can be healthy and low-cost <a href="https://www.heartfoundation.org.au/getmedia/71522940-decf-436a-ba44-cd890dc18036/Meat-Free-Recipe-Booklet.pdf">additions to many meals</a>. Where you can, choose canned varieties with no added salt, especially when buying baked beans. 3. Add herbs and spices to your tofu Tofu can be a great alternative to meat. Check the label and pick the option with the highest calcium content. We found flavoured tofu was higher in salt and sugar content than minimally processed tofu. So it’s best to pick an unflavoured option and add your own flavours with spices and herbs. 4. Check the calcium When choosing a non-dairy alternative to milk, such as those made from soy, oat, or rice, check it is fortified with calcium. A good alternative to traditional dairy will have at least 100mg of calcium per 100g. 5. Watch for saturated fat If looking for a lower saturated fat option, almond, soy, rice and oat varieties of milk and yoghurt alternatives have much lower saturated fat content than coconut options. Pick those with less than 3g per 100g.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/222991/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-marchese-1271636">Laura Marchese</a>, PhD Student at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, NHMRC Emerging Leadership Fellow and Senior Research Fellow at the Institute for Physical Activity and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Foods to avoid if you have acid reflux or digestion issues

What common foods are good and bad for your belly? Foods containing rapidly fermentable carbohydrates called FODMAPs can feed bacteria in the gut and may be responsible for gut inflammation, gas, bloating and other uncomfortable tummy troubles in some people. Cutting back on foods that contain FODMAPs may help improve your digestion and eliminate GI problems. “An anti-inflammatory diet is high in fibre-rich foods, which promote the growth of healthy bacteria in the gut (one way the diet assists to control inflammation),” says registered dietitian Maxine Smith. A FODMAP diet, which is low in fermentable carbohydrates, is low in fibre and may be beneficial for some people with gastrointestinal problems. In general, a low FODMAPs diet isn’t recommended for people unless they have a condition like irritable bowel syndrome that hasn’t responded to other treatments or dietary changes. Watermelon: Avoid This lovely summer treat isn’t as harmless as all the water it contains. Watermelon is high in fructose, fructans and polyols, which are FODMAPs. Remember, the more the FODMAPs, the more potential for tummy trouble in people who are sensitive to them. Fermented foods: Enjoy some, avoid some Some fermented foods are good for your tummy; others can create problems for certain people, according to an article published by Harvard Medical School. Fermented foods include wine, cheese, vinegar, miso, yoghurt, sauerkraut and pickles. In yoghurt, milk is combined with bacteria that break down some of the lactose, so what remains may be easier for your stomach to process. So fermented foods such as yoghurt are often considered “probiotic foods” that are good for your gut. Look for dairy products that are low in lactose and your digestion should be A-OK. Pistachios, cashews, hazelnuts and almonds: Avoid Most nuts are good for your tummy, but pistachios and cashews are high in fructans and GOS (galacto-oligosaccharides), both FODMAPs. Hazelnuts and almonds are a little higher in FODMAPs than some other nuts so eat them in limited quantities (10 nuts or 1 tablespoon of nut butter per serving). Steer clear of almond milk, which is made with large amounts of almonds. Acidic foods: Enjoy with caution In almost every list of “the worst foods for digestion,” you’ll find acidic foods like oranges and tomatoes. These are commonly thought to cause heartburn, but studies have shown that acidic foods don’t have any effect on LES pressure (or pressure on the lower oesophageal sphincter, a valve that acts as the doorway between the oesophagus and the stomach) and don’t cause heartburn symptoms. However, if you have severe acid reflux that hasn’t been treated and has irritated the oesophagus, acidic foods can be like “salt in the wound.” So if you find that oranges or tomatoes do make your heartburn feel worse, replace them with other fruits. Dairy foods: Enjoy some, avoid some Not all dairy foods have equal amounts of lactose, which can cause digestion issues, and even those with lactose intolerance are usually okay with small amounts of lactose. That means that not all milk, cheeses and dairy products are tummy twisters. Hard cheeses, like cheddar, Swiss or Parmesan, generally have less than a gram of lactose per serving. According to the Cleveland Clinic, you may want to avoid dairy such as “chocolate shakes or drinks, milkshakes, whole milk fat yoghurt, whole milk fat (4%) cottage cheese, and full-fat cheese.” Soy foods: Enjoy some, avoid some Whole soybeans (often sold as edamame), like other beans, are a source of GOS, which are hard-to-digest chains of sugars. Tofu and tempeh are made using processes that eliminate some of the GOS, making them easier on your digestion. What about soy milk? It depends. If soy milk is made with only soybean isolates or soy protein, then it should be low in FODMAPs. Soy milk made with whole soybeans is likely a source of GOS, making it a gassy beverage for some, so read the ingredients. Blackberries: Avoid Strawberries, blueberries, blackberries – which is the odd one out here? Blackberries are also rich in antioxidants, but they have sugar alcohols called polyols, which are difficult to digest and can cause some real problems if your stomach is sensitive. (Check out these foods that GI doctors always avoid.) Tomato and tomato products: Enjoy some, avoid some Fresh and canned tomatoes are fine for your tummy. But tomato paste is a concentrated form of tomato that has excess fructose, a FODMAP that makes it a no-no except in small quantities. And tomato sauces? If they’re homemade, they’re fine to eat (just don’t cook it to the point where all the juices are lost). Most commercial sauces have onions and garlic (FODMAPs), added sugar (which may make it carb-dense), and salt (which bloats you), so steer clear of the store-bought variety. Grapefruit: Enjoy with caution Grapefruit does have hard-to-digest fructans, so you should try to limit how much you eat. A few sections should be okay, but don’t eat a half a grapefruit. If you’re looking for citrus, lemon, lime and oranges are your best bets. Milk: Enjoy some, avoid some Most types of animal milk are high in tummy twisting lactose – that means goat’s or sheep’s milk can be just as problematic as cow’s milk. Plant-based milks, such as coconut milk, soy milk or almond milk, are technically not milk at all and generally do not have any lactose. Some, however, including almond milk and soy milk, may contain other FODMAPs that harm your digestion. Corn: Avoid Corn comes in many varieties, such as popcorn, on the cob and in polenta. Fresh sweet corn contains two types of FODMAPs, making corn challenging for some people to digest. Popcorn feels like a light and healthy snack, but it’s actually carb-dense (it has about 64 grams of carbs per 100 grams), which can upset digestion. Whole cornmeal and corn tortillas seem to be better tolerated by most people. Whole grain polenta is also low in FODMAPs. You may need to experiment a little to figure out which corn products work for you. And stick with only limited quantities (up to 1 cup cooked per serving). Common cabbage: Enjoy Cabbage usually makes it on all the lists of foods that make you gassy, but common green cabbage doesn’t deserve that reputation. It’s actually low in FODMAPs and most of us break it down very well. Red cabbage also seems to be well-tolerated, but savoy and napa cabbage is much higher in FODMAPs and should be limited if you tend to suffer from gas and bloating. Hot sauce: Enjoy with caution Tolerance to hot sauce is very individual. It’s more problematic for those with heartburn. If you would like to try some, pick a brand without onion and garlic.

You can’t reverse the ageing process but these 5 things can help you live longer

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> At this time of year many of us resolve to prioritise our health. So it is no surprise there’s a <a href="https://digiday.com/marketing/health-food-brands-ramp-up-marketing-efforts-around-consumers-new-years-resolutions/">roaring trade</a> of products purporting to guarantee you live longer, be healthier and look more youthful. While an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4822264/">estimated</a> 25% of longevity is determined by our genes, the rest is determined by what we do, day to day. There are no quick fixes or short cuts to living longer and healthier lives, but the science is clear on the key principles. Here are five things you can do to extend your lifespan and improve your health. <h2>1. Eat a predominantly plant-based diet</h2> What you eat has a huge impact on your health. The evidence overwhelmingly <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8210981/#:%7E:text=According%20to%20an%20expansive%20review,13%20Given%20that%20so%20many">shows</a> eating a diet high in plant-based foods is associated with health and longevity. If you eat more plant-based foods and less meat, processed foods, sugar and salt, you reduce your risk of a range of illnesses that shorten our lives, including heart disease and cancer. Plant-based foods <a href="https://www.nature.com/articles/s41398-019-0552-0">are rich</a> in nutrients, phytochemicals, antioxidants and fibre. They’re also anti-inflammatory. All of this protects against damage to our cells as we age, which helps prevent disease. No particular diet is right for everyone but one of the most studied and <a href="https://www.hsph.harvard.edu/nutritionsource/healthy-weight/diet-reviews/mediterranean-diet/#:%7E:text=%5B6%5D%20Those%20who%20had%20the,who%20had%20the%20lowest%20adherence.">healthiest</a> is the <a href="https://www.eatingwell.com/article/291120/mediterranean-diet-for-beginners-everything-you-need-to-get-started/">Mediterranean diet</a>. It’s based on the eating patterns of people who live in countries around the Mediterranean Sea and emphases vegetables, fruits, wholegrains, legumes, nuts and seeds, fish and seafood, and olive oil. <h2>2. Aim for a healthy weight</h2> Another important way you can be healthier is to try and achieve a healthy weight, as obesity <a href="https://www.healthline.com/health/obesity/how-obesity-affects-body">increases the risk</a> of a number of health problems that shorten our lives. Obesity puts strain on all of our body systems and has a whole myriad of physiological effects including causing inflammation and hormonal disturbances. These <a href="https://www.ncbi.nlm.nih.gov/books/NBK572076/">increase your chances</a> of a number of diseases, including heart disease, stroke, high blood pressure, diabetes and a number of cancers. In addition to affecting us physically, obesity is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6052856/">associated with</a> poorer psychological health. It’s linked to depression, low self-esteem and stress. One of the biggest challenges we face in the developed world is that we live in an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6817492/">environment</a> that promotes obesity. The ubiquitous marketing and the easy availability of high-calorie foods our bodies are hard-wired to crave mean it’s easy to consume too many calories. <h2>3. Exercise regularly</h2> We all know that exercise is good for us – the <a href="https://www.insurancebusinessmag.com/au/news/breaking-news/hcf-reveals-australias-most-popular-new-years-resolutions-for-2023-431665.aspx">most common resolution</a> we make this time of year is to do more exercise and to get fitter. Regular exercise <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">protects</a> against chronic illness, lowers your stress and improves your mental health. While one of the ways exercising helps you is by supporting you to control your weight and lowering your body fat levels, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1402378/#:%7E:text=For%20instance%2C%20routine%20physical%20activity,HDL%5D%20cholesterol%20levels%20and%20decreased">effects</a> are broader and include improving your glucose (blood sugar) use, lowering your blood pressure, reducing inflammation and improving blood flow and heart function. While it’s easy to get caught up in all of the hype about different exercise strategies, the evidence <a href="https://www.medicalnewstoday.com/articles/320760">suggests</a> that any way you can include physical activity in your day has health benefits. You don’t have to run marathons or go to the gym for hours every day. Build movement into your day in any way that you can and do things that you enjoy. <h2>4. Don’t smoke</h2> If you want to be healthier and live longer then don’t smoke or vape. Smoking cigarettes affects almost every organ in the body and is associated with both a shorter and lower quality of life. There is no safe level of smoking – every cigarette increases your <a href="https://theconthatkills.org.au/?utm_source=googlesearch&utm_medium=search&utm_campaign=theconthatkills23&utm_content=RSA&gclid=Cj0KCQjwqP2pBhDMARIsAJQ0Czrlep6EQHC-8_9xUhpz0h9v2ZglMF-6-k7_65awq8FxVaIL5HRoivwaAqJwEALw_wcB&gclsrc=aw.ds">chances of developing</a> a range of cancers, heart disease and diabetes. Even if you have been smoking for years, by giving up smoking at any age you can experience <a href="https://www.cdc.gov/tobacco/quit_smoking/how_to_quit/benefits/index.htm">health benefits</a> almost immediately, and you can reverse many of the harmful effects of smoking. If you’re thinking of switching to vapes as a healthy long term option, <a href="https://theconversation.com/can-vaping-help-people-quit-smoking-its-unlikely-204812">think again</a>. The long term health effects of vaping are not fully understood and they come with their own <a href="https://theconversation.com/no-vapes-arent-95-less-harmful-than-cigarettes-heres-how-this-decade-old-myth-took-off-203039">health risks</a>. <h2>5. Prioritise social connection</h2> When we talk about living healthier and longer, we tend to focus on what we do to our physical bodies. But one of the most important discoveries over the past decade has been the recognition of the importance of spiritual and psychological health. People who are lonely and socially isolated have a much higher risk of dying early and are <a href="https://healthnews.com/longevity/healthspan/social-connection-and-longevity/#:%7E:text=One%20of%20the%20biggest%20benefits,the%20following%20factors%20and%20influences.">more likely</a> to suffer from heart disease, stroke, dementia as well as anxiety and depression. Although we don’t fully understand the mechanisms, it’s likely due to both behavioural and biological factors. While people who are more socially connected are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150158/">more likely</a> to engage in healthy behaviours, there also seems to be a more direct physiological effect of loneliness on the body. So if you want to be healthier and live longer, build and maintain your connections to others.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/214580/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

5 ways to avoid weight gain and save money on food this Christmas

<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> As Christmas approaches, so does the challenge of healthy eating and maintaining weight-related goals. The season’s many social gatherings can easily tempt us to indulge in calorie-rich food and celebratory drinks. It’s why we typically <a href="https://www.nejm.org/doi/full/10.1056/NEJMc1602012">gain weight</a> over Christmas and then struggle to take it off for the <a href="https://www.sciencedirect.com/science/article/pii/S0031938414001528">remainder of the year</a>. Christmas 2023 is also exacerbating cost-of-living pressures, prompting some to rethink their food choices. Throughout the year, <a href="https://dvh1deh6tagwk.cloudfront.net/finder-au/wp-uploads/2023/03/Cost-of-Living-Report-2023.pdf">71% of Australians</a> – or 14.2 million people – <a href="https://retailworldmagazine.com.au/rising-cost-of-living-forces-aussies-to-change-diets/">adapted</a> their eating behaviour in response to rising costs. Fortunately, there are some simple, science-backed hacks for the festive season to help you celebrate with the food traditions you love without impacting your healthy eating habits, weight, or hip pocket. <h2>1. Fill up on healthy pre-party snacks before heading out</h2> If your festive season is filled with end-of-year parties likely to tempt you to fill up on finger foods and meals high in fat, salt, and sugar and low in nutritional value, have a healthy pre-event snack before you head out. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5015032/#sec-a.g.atitle">Research</a> shows carefully selected snack foods can impact satiety (feelings of fullness after eating), potentially reducing the calories you eat later. High-protein, high-fibre snack foods have the strongest effect: because they take longer to digest, our hunger is satisfied for longer. So enjoy a handful of nuts, a tub of yoghurt, or a serving of hummus with veggie sticks before you head out to help keep your healthy eating plan on track. <h2>2. Skip the low-carb drinks and enjoy your favourites in moderation</h2> Despite the marketing promises, low-carb alcoholic drinks <a href="https://onlinelibrary.wiley.com/doi/10.1002/hpja.531">aren’t better for our health or waistlines</a>. Many low-carb options have a similar amount of carbohydrates as regular options but lull us into thinking they’re better, so we drink more. A <a href="https://www.vichealth.vic.gov.au/sites/default/files/K-013_Low-carb-beer_FactSheet_FINAL.pdf">survey</a> found 15% of low-carb beer drinkers drank more beer than they usually would because they believed it was healthier for them. A typical lager or ale will contain less than 1.5 grams of carbohydrate per 100 ml while the “lower-carb” variety can range anywhere from 0.5 grams to 2.0 grams. The calories in drinks come from the alcohol itself, not the carbohydrate content. Next time you go to order, think about the quantity of alcohol you’re drinking rather than the carbs. Make sure you sip lots of water in between drinks to stay hydrated, too. <h2>3. Don’t skimp on healthy food for Christmas Day – it’s actually cheaper</h2> There’s a perception that healthy eating is more expensive. But studies show this is a misconception. A <a href="https://southwesthealthcare.com.au/swh-study-finds-eating-a-healthier-diet-is-actually-cheaper-at-the-checkout/#:%7E:text=A%20recent%20study%20from%20the,does%20not%20meet%20the%20guidelines">recent analysis</a> in Victoria, for example, found following the Australian Dietary Guidelines cost the average family A$156 less a fortnight than the cost of the average diet, which incorporates packaged processed foods and alcohol. So when you’re planning your Christmas Day meal, give the pre-prepared, processed food a miss and swap in healthier ingredients: <ul> <li> swap the heavy, salted ham for leaner and lighter meats such as fresh seafood. Some seafood, such as prawns, is also tipped to be cheaper this year thanks to <a href="https://www.smh.com.au/goodfood/lobsters-up-prawns-stable-a-buying-guide-to-seafood-this-christmas-20231208-p5eq3m.html">favourable weather conditions</a> boosting local supplies </li> <li> for side dishes, opt for fresh salads incorporating seasonal ingredients such as mango, watermelon, peach, cucumber and tomatoes. This will save you money and ensure you’re eating foods when they’re freshest and most flavoursome </li> </ul> <ul> <li> if you’re roasting veggies, use healthier cooking oils like olive as opposed to vegetable oil, and use flavourful herbs instead of salt </li> <li> if there’s an out-of-season vegetable you want to include, look for frozen and canned substitutes. They’re cheaper, and <a href="https://www.sciencedirect.com/science/article/pii/S0889157517300418">just as nutritious</a> and tasty because the produce is usually frozen or canned at its best. Watch the sodium content of canned foods, though, and give them a quick rinse to remove any salty water </li> <li> give store-bought sauces and dressings a miss, making your own from scratch using fresh ingredients. </li> </ul> <h2>4. Plan your Christmas food shop with military precision</h2> Before heading to the supermarket to shop for your Christmas Day meal, create a detailed meal plan and shopping list, and don’t forget to check your pantry and fridge for things you already have. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4586574/">Eating beforehand</a> and shopping with a plan in hand means you’ll only buy what you need and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8206473/">avoid impulse purchasing</a>. When you’re shopping, price check everything. Comparing the cost per 100 grams is the most effective way to save money and get the best value. Check prices on products sold in different ways and places, too, such as nuts you scoop yourself versus prepacked options. <h2>5. Don’t skip breakfast on Christmas Day</h2> We’ve all been tempted to skip or have a small breakfast on Christmas morning to “save” the calories for later. But this plan will fail when you sit down at lunch hungry and find yourself eating far more calories than you’d “saved” for. <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. What you eat for breakfast on Christmas morning is just as important too – choosing the right foods will <a href="https://theconversation.com/im-trying-to-lose-weight-and-eat-healthily-why-do-i-feel-so-hungry-all-the-time-what-can-i-do-about-it-215808">help you manage your appetite</a> and avoid the temptation to overindulge later in the day. <a href="https://pubmed.ncbi.nlm.nih.gov/24703415/">Studies</a> show a breakfast containing protein-rich foods, such as eggs, will leave us feeling fuller for longer. So before you head out to the Christmas lunch, have a large, nutritionally balanced breakfast, such as eggs on wholegrain toast with avocado.

So improving your diet can also be an important way to reduce the chance of developing chronic disease. <h2>First, what are the dietary guidelines?</h2> The guidelines provide information on the quantity and types of foods most Australians should consume to promote overall health and wellbeing. Recommendations include eating a wide variety of nutritious foods from the main five food groups: <ul> <li>vegetables and legumes</li> <li>fruit</li> <li>grains</li> <li>lean meats and meat alternatives such as tofu, nuts and legumes</li> <li>dairy products.</li> </ul> The guidelines recommend limiting our intake of foods high in saturated fat, added salt, added sugars and alcohol. <h2>What are Australians eating?</h2> Fewer than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/dietary-behaviour/latest-release">7%</a> of Australians eat sufficient vegetables, in line with the Australian Dietary Guidelines. In fact, Australians have an average healthy diet score of <a href="https://www.csiro.au/-/media/News-releases/2023/Total-Wellbeing-Diet-Health-Score/Diet-score-2023-Report_September.pdf">55 out of 100</a> – barely passing. Foods that aren’t part of a food group are known as “discretionary” items, which includes alcohol, cakes, biscuits, chocolate and confectionery and most takeaway foods. Because they’re typically high in kilojoules, saturated fat, sodium and added sugars, the Australian Dietary Guidelines recommend they only be eaten occasionally and in small amounts (ideally zero serves). For many households, discretionary items make up a big portion of their grocery shop. Australians consume an average of <a href="https://www.csiro.au/-/media/News-releases/2023/Total-Wellbeing-Diet-Health-Score/Diet-score-2023-Report_September.pdf">28 serves</a> of discretionary choices per week (equal to 28 doughnuts, 28 slices of cake, or 28 cans of soft drink or beer). This is an increase of ten serves since 2015. One recent <a href="https://link.springer.com/article/10.1186/s12966-022-01389-8">study</a> estimated 55% of Australians’ total energy intake was from discretionary items. <h2>What did the researchers find?</h2> Researchers from the Health Promotion Team at South West Healthcare <a href="https://southwesthealthcare.com.au/wp-content/uploads/SWH-HP-Healthy-Diets-ASAP-Protocol-Warrnambool-Report-2023.pdf">recently</a> visited four local supermarkets and takeaway stores in Warrnambool, Victoria, and purchased two baskets of groceries. One basket met the Australian Dietary Guidelines (basket one), the other aligned with the typical dietary intake of Australians (basket two). They compared prices between the two and found basket one would cost approximately $167 less per fortnight for a family of four at the most affordable supermarket. That’s equal to $4,342 a year. Basket one was sufficient to supply a family of four for a fortnight, and aligned with the Australian Dietary Guidelines. It cost $724 and included: <ol> <li>fruit and vegetables (made up 31% of the fortnightly shop)</li> <li>grains and cereals (oats, cornflakes, bread, rice, pasta, Weet-bix)</li> <li>lean meats and alternatives (mince, steak, chicken, tuna, eggs, nuts)</li> <li>milk, yoghurt and cheese</li> <li>oils and spreads (olive oil).</li> </ol> Basket two reflected the current average Australian fortnightly shop for a family of four. In the project, the team spent over half of the fortnightly shop on processed and packaged foods, of which 21% was spent on take-away. This is based on actual dietary intake of the general population reported in the 2011-2012 <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/australian-health-survey-nutrition-first-results-foods-and-nutrients/latest-release#:%7E:text=Food%20consumption,across%20the%20major%20food%20groups.">Australian Health Survey</a>. Basket two cost $891 and included: <ol> <li>fruit and vegetables (made up 13% of the fortnightly shop)</li> <li>grains and cereals (oats, cornflakes, bread, rice, pasta, Weet-bix)</li> <li>lean meats and alternatives (mince, steak, chicken, tuna, eggs, nuts)</li> <li>milk, yogurt and cheese</li> <li>oils and spreads (olive oil, butter)</li> <li>drinks (soft drink, fruit juice)</li> <li>desserts and snacks (muffins, sweet biscuits, chocolate, ice cream, potato chips, muesli bars)</li> <li>processed meats (sausages, ham)</li> <li>convenience meals</li> <li>fast food (pizza, meat pie, hamburger, fish and chips)</li> <li>alcohol (beer, wine).</li> </ol> <h2>But a healthy basket is still unaffordable for many</h2> While this piece of work, and other <a href="https://www.mdpi.com/1660-4601/15/11/2469">research</a>, suggests a healthy diet is less expensive than an unhealthy diet, affordability is still a challenge for many families. The Warrnambool research found basket one (which aligned with guidelines) was still costly, requiring approximately 25% of a median household income. This is unaffordable for many. For a household reliant on welfare, basket one would require allocating 26%-38% of their income. This highlights how the rising cost of living crisis is affecting those already facing financial difficulties. Around 3.7 <a href="https://reports.foodbank.org.au/foodbank-hunger-report-2023/">million</a> Australian households did not have access to enough food to meet their basic needs at some point in the last 12 months. Policy action is needed from the Australian government to make recommended diets more affordable for low socioeconomic groups. This means lowering the costs of healthy foods and ensuring household incomes are sufficient. <h2>What else can you do to cut your spending?</h2> To help reduce food costs and support your health, reducing discretionary foods could be a good idea. Other ways to reduce your grocery bill and keep your food healthy and fresh include: <ul> <li> planning for some meatless meals each week. Pulses (beans, lentils and legumes) are nutritious and cheap (a can is <a href="https://coles.com.au/product/coles-chick-peas-420g-8075852?uztq=46abcbb7e16253b0cdc3e6c5bbe6a3f0&cid=col_cpc_Generic%7cColesSupermarkets%7cPLA%7cCatchAll%7cAustralia%7cBroad&s_kwcid=AL!12693!3!675842378376!!!g!326304616489!&gad_source=1&gclid=CjwKCAjwkY2qBhBDEiwAoQXK5SceYhU2VtKepNLXWN218GH8Cp8Vs9cnYynCBwRqQPaW3UYNX2SVIBoC_6EQAvD_BwE&gclsrc=aw.ds">less than $1.50</a>.

Taste depends on nature and nurture. Here are 7 ways you can learn to enjoy foods you don’t like

<a href="https://theconversation.com/profiles/nicholas-archer-181464">Nicholas Archer</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a> and <a href="https://theconversation.com/profiles/astrid-poelman-1481227">Astrid Poelman</a>, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a> You’re out for dinner with a bunch of friends, one of whom orders pizza with anchovies and olives to share, but you hate olives and anchovies! Do you pipe up with your preferred choice – Hawaiian – or stay quiet? This scene plays out every day around the world. Some people ferociously defend their personal tastes. But many would rather expand their palate, and not have to rock the boat the next time someone in their friend group orders pizza. Is it possible to train your tastebuds to enjoy foods you previously didn’t, like training a muscle at the gym? <h2>What determines ‘taste’?</h2> Taste is a complex system we evolved to help us navigate the environment. It helps us select foods with nutritional value and reject anything potentially harmful. Foods are made up of different compounds, including nutrients (such as proteins, sugars and fats) and <a href="https://www.youtube.com/watch?v=2P_0HGRWgXw">aromas</a> that are detected by sensors in the mouth and nose. These sensors create the <a href="https://www.youtube.com/watch?v=MZn2PMUWO-Y">flavour of food</a>. While taste is what the tastebuds on your tongue pick up, flavour is the combination of how something smells and tastes. Together with texture, appearance and sound, these senses collectively influence your food preferences. <figure><iframe src="https://www.youtube.com/embed/MZn2PMUWO-Y?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Flavour is the overall impression you get when eating.</figcaption></figure> Many factors influence food preferences, including age, genetics and environment. We each live in our own sensory world and no two people will have the same <a href="https://theconversation.com/curious-kids-why-do-some-people-find-some-foods-yummy-but-others-find-the-same-foods-yucky-77671">experience while eating</a>. Food preferences also change with age. Research has found young children have a <a href="https://pubmed.ncbi.nlm.nih.gov/24452237/">natural preference</a> for sweet and salty tastes and a dislike of bitter tastes. As they grow older their ability to like bitter foods grows. Emerging evidence shows bacteria in saliva can also produce enzymes that influence the taste of foods. For instance, saliva has been shown to cause the release of sulphur aromas in cauliflower. The <a href="https://www.acs.org/pressroom/presspacs/2021/acs-presspac-september-22-2021/childrens-dislike-of-cauliflower-broccoli-could-be-written-in-their-microbiome.html">more sulphur that is produced</a>, the less likely a kid is to enjoy the taste of cauliflower. <h2>Nature versus nurture</h2> Both genetics and the environment play a crucial role in determining food preferences. Twin studies estimate genetics have a moderate influence on food preferences (between 32% and 54%, depending on the food type) in <a href="https://www.sciencedirect.com/science/article/pii/S000291652305027X?via%3Dihub">children</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/27385609/">adolescents</a> and <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/dietary-patterns-and-heritability-of-food-choice-in-a-uk-female-twin-cohort/8507AAF01330C599BAC62BCC0EF4CF06">adults</a>. However, since our cultural environment and the foods we’re exposed to also shape our preferences, these <a href="https://pubmed.ncbi.nlm.nih.gov/24452237/">preferences are learned</a> to a large degree. A lot of this learning takes place during childhood, at home and other places we eat. This isn’t textbook learning. <a href="https://www.cabidigitallibrary.org/doi/10.1079/9780851990323.0093">It’s learning</a> by experiencing (eating), which typically leads to increased liking of the food – or by watching what others do (modelling), which can lead to both positive or negative associations. <a href="https://www.sciencedirect.com/science/article/pii/S000291652305027X?via%3Dihub">Research</a> has shown how environmental influences on food preferences change between childhood and adulthood. For children, the main factor is the home environment, which makes sense as kids are more likely to be influenced by foods prepared and eaten at home. Environmental factors influencing adults and adolescents are more varied. <h2>The process of ‘acquiring’ taste</h2> Coffee and beer are good examples of bitter foods people “acquire” a taste for as they grow up. The ability to overcome the dislike of these is largely due to: <ul> <li> the social context in which they’re consumed. For example, in many countries they may be associated with passage into adulthood. </li> <li> the physiological effects of the compounds they contain – caffeine in coffee and alcohol in beer. Many people find these effects desirable. </li> </ul> But what about acquiring a taste for foods that don’t provide such desirable feelings, but which are good for you, such as kale or fatty fish? Is it possible to gain an acceptance for these? Here are some strategies that can help you learn to enjoy foods you currently don’t: <ol> <li> eat, and keep eating. Only a small portion is needed to build a liking for a specific taste over time. It may take 10–15 attempts or more before you can say you “like” the food. </li> <li> <a href="https://www.sciencedirect.com/science/article/pii/S0950329302001106">mask bitterness</a> by eating it with other foods or ingredients that contain salt or sugar. For instance, you can pair bitter rocket with a sweet salad dressing. </li> <li> eat it repeatedly in a positive context. That could mean eating it after playing your favourite sport or with people you like. Alternatively, you could eat it with foods you already enjoy; if it’s a specific vegetable, try pairing it with your favourite protein. </li> <li> eat it when you’re hungry. In a hungry state you’ll be more willing to accept a taste you might not appreciate on a full stomach. </li> <li> remind yourself why you want to enjoy this food. You may be changing your diet for health reasons, or because you’ve moved countries and are struggling with the local cuisine. Your reason will help motivate you. </li> <li> start young (if possible). It’s easier for children to learn to like new foods as their tastes are less established. </li> <li> remember: the more foods you like, the easier it’ll become to learn to like others. </li> </ol> A balanced and varied diet is essential for good health. <a href="https://www.sciencedirect.com/science/article/pii/S0195666315003438?ref=pdf_download&fr=RR-2&rr=82a5fd5069821f63">Picky eating</a> can become a problem if it leads to vitamin and mineral deficiencies – especially if you’re avoiding entire food groups, such as vegetables. At the same time, eating too many tasty but energy-dense foods can increase your risk of chronic disease, including obesity. Understanding how your food preferences have formed, and how they can evolve, is a first step to getting on the path of healthier eating.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/215999/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nicholas-archer-181464">Nicholas Archer</a>, Research Scientist, Sensory, Flavour and Consumer Sciences, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a> and <a href="https://theconversation.com/profiles/astrid-poelman-1481227">Astrid Poelman</a>, Principal Researcher, Public Health & Wellbeing Group, <a href="https://theconversation.com/institutions/csiro-1035">CSIRO</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

“Sounds like some terrible rash”: Iconic Aussie food Jamie Oliver has never tasted

Jamie Oliver has been visiting Australia on and off for the past 20 years - but he has never tried Tim Tams. The celebrity chef revealed that he never tried the classic Aussie treat during an interview with The Today Show on Friday. Jamie touched down in Sydney recently ahead of his 10-year anniversary with Royal Caribbean cruises, and was onboard the Ovation of the Seas when he was asked to pick his favourite between Vegemite toast or Tim Tams. “What’s that in English? What did you just say?" the celebrity chef asked. “Ah, Vegemite toast. What’s a Tim Tam? What is it, it sounds like some terrible rash,” he joked. The presenter told him that it was a chocolate biscuit and got him to try one after finding a tray on the ship. “This is the moment of truth – this thing I have never had before,” Jamie said before he took a bite out of the popular snack. “Very, very nice … I will never forget this moment.” The 48-year-old chef first came to Australia when he was just 24 years old. Ever since, he's been travelling in an out of the country after falling in love with it. “I normally came, in the old world, every year, but obviously Covid threw a little curve ball in there,” he told news.com.au. “I just love it here. It always feels like weirdly, my true home. I feel like my style of cooking, my personality, my ridiculous jokes seem to go down better here than back home.” Image: Getty

We found 3 types of food wasters, which one are you?

<a href="https://theconversation.com/profiles/trang-nguyen-1454838">Trang Nguyen</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/patrick-oconnor-109973">Patrick O'Connor</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Each year, Australian households discard about <a href="https://workdrive.zohopublic.com.au/external/06152b9ff5971843391f39fc4d32a847e56fb907c167a4a645887b0a4bc43000">2.5 million tonnes of food</a>. Most (73%) of this food waste <a href="https://www.sciencedirect.com/science/article/pii/S0959652622042081">ends up in landfill</a>. This is costly and contributes to <a href="https://pubmed.ncbi.nlm.nih.gov/37118273/">escalating greenhouse gas emissions</a>, because food waste rotting in landfill produces methane. So reducing household food waste and diverting it from landfill saves money, improves food security and benefits the environment. To address the problem, we need to understand how people generate and dispose of food waste. In <a href="https://doi.org/10.1016/j.foodqual.2023.105000">our new study</a>, we found households fell into three categories – based on the amount of food wasted, how much of that waste was avoidable and how it was sorted. These insights into consumer behaviour point to where the most worthwhile improvements can be made. <figure><iframe src="https://www.youtube.com/embed/JvAFaD5f1Lo?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption></figcaption></figure> <h2>Three types of households</h2> We conducted an online survey of 939 households in metropolitan Adelaide between April and May 2021. The sample closely matched the national Australian population in terms of gender, age and income. We asked about the types of food waste produced, the amount of food waste typically discarded in a week and motivations towards reducing and sorting food waste. We identified three distinct types of households: Warriors are typically older and highly motivated to reduce and sort food waste. They generate minimal waste (9.6 litres per week), such as bones and vegetable peels, that is mostly unavoidable. This group comprised 39.6% of the sample. Strugglers mainly consist of families with children who produce the largest amount of food waste (33.1 litres per week). They produce the highest proportion of avoidable food waste, such as uneaten fruits and vegetables, bread and cereals. They are moderately motivated to reduce and sort food waste, but more than half of their food waste still ends up in landfill. This group made up 19.6% of the sample. Slackers are generally younger. They show little concern about reducing or sorting food waste. Slackers produce the smallest amount of food waste overall (9 litres a week), but the proportion of avoidable food waste (such as mixed leftovers) is significantly higher (38.9%) compared to warriors (24.5%). They are more than twice as likely to live in units, with 17.2% doing so, compared to just 7.8% of warriors. This group was 40.8% of the sample. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?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/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=361&fit=crop&dpr=1 600w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=361&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=361&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=454&fit=crop&dpr=1 754w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=454&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/550951/original/file-20230928-27-f7cw8e.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=454&fit=crop&dpr=3 2262w" alt="Graphic explainer showing the three types of households with their typical characteristics and food waste behaviours." /></a><figcaption>The three types of households with their typical characteristics and food waste behaviours. <a class="source" href="https://doi.org/10.1016/j.foodqual.2023.105000">Trang Nguyen using Canva.com</a>, <a class="license" href="http://creativecommons.org/licenses/by-nc-nd/4.0/">CC BY-NC-ND</a></figcaption></figure> <h2>What can households do about their food waste?</h2> Reducing household food waste involves changing behaviours in both food management (“upstream”) and waste management (“downstream”). Upstream measures aim to prevent food waste in the first place. For example, households can avoid buying or cooking too much food. Supporting households to plan and buy just the right amount of food is a great starting point. Once food waste has been produced, downstream measures come into play. The focus shifts to how we handle and dispose of this waste. When households engage in food waste recycling they <a href="https://doi.org/10.3390/su131911099">start thinking more</a> about their behaviour including purchasing and cooking. In Australia, food waste management is mainly the responsibility of local councils. There are three ways to target household food waste management and drive behavioural change: <ul> <li> providing kerbside collection of food organics and garden organics, also known as “FOGO” </li> <li> changing social norms around food waste </li> <li> offering economic incentives and disincentives. </li> </ul> <h2>1. Providing a FOGO system</h2> Councils should provide this option at a minimum. This ensures sufficient infrastructure is available to support motivated households to sort food waste. Unfortunately <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">fewer than half of Australian councils</a> provide a garden organics system and only a quarter of councils provide a FOGO system. You can explore <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">the FOGO interactive map</a> to see how your area stacks up. <a href="https://www.greenindustries.sa.gov.au/resources/adelaide-metro-kerbside-waste-performance-report-2021-22">Most councils in metropolitan Adelaide</a> provide access to food waste recycling through the FOGO bin. But <a href="https://doi.org/10.1016/j.jclepro.2022.134636">our research</a> indicates more than half of household food waste still ends up in landfill. So we need additional programs to promote more sustainable behaviours. <h2>2. Changing social norms</h2> Social norms, the unspoken rules about what behaviours are deemed appropriate, can drive behavioural change. Examples of promoting social norms around food waste reduction include a <a href="https://www.stopfoodwaste.com.au/stop-food-waste-nationwide-consumer-campaign-summit-communique/">nationwide consumer campaign</a> on stopping food waste and the <a href="https://www.cityofadelaide.com.au/resident/recycling-waste/kitchen-caddies/">kitchen caddy</a> for benches to increase convenience for collecting food waste. But our research suggests some groups, like slackers, remain unmotivated without additional incentives. Economic incentives might motivate this group to engage in more sustainable behaviours. <h2>3. Economic incentives</h2> Currently, Australians pay for waste management through their council rates. This is a “pay-as-you-own” system. The cost is determined by the property’s value, regardless of the amount of waste generated. Renters indirectly contribute to this cost by paying rent. Neither owner-occupiers nor renters have any incentive to reduce waste generation when the cost is levied on property value rather than the amount of waste. An alternative approach gaining momentum in other parts of the world is the “pay-as-you-throw” approach, such as <a href="https://www.collectors2020.eu/wcs-ppw/stockholm-se/">Stockholm</a> and <a href="https://pocacito.eu/sites/default/files/WasteCharging_Taipei.pdf">Taipei</a>. This system charges households based on the weight of their waste, usually the general waste that needs to be discarded in landfill, while the collection of food waste and other recyclables remains free to encourage waste sorting. Recent <a href="https://doi.org/10.1016/j.jclepro.2023.137363">research</a> in Italy shows pay-as-you-throw schemes result in significant reductions in both the quantity of waste and costs associated with waste disposal in many Italian municipalities. The reduced costs flow on to savings for councils that could potentially reduce waste management fees passed on to homeowners and renters through council rates. Giving households incentives to reduce waste and find alternatives to disposal encourages residents to place a higher value on food that may otherwise be sent to landfill. <h2>Reducing food waste is a win-win</h2> Tackling food waste is a win-win for people and the planet. It’s worth using various approaches to encourage people to change their behaviour. Our findings can help inform the design of interventions aimed at reducing and sorting food waste in specific segments of the Australian population.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/214482/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <figure><iframe src="https://www.youtube.com/embed/Dx7RWtfgbVw?wmode=transparent&start=11" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>No time to waste: Halving Australia’s food waste by 2030 (Fight Food Waste Cooperative Research Centre)</figcaption></figure> <a href="https://theconversation.com/profiles/trang-nguyen-1454838">Trang Nguyen</a>, Postdoctoral Fellow, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/patrick-oconnor-109973">Patrick O'Connor</a>, Associate Professor, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

7 tips for matching wine with food

Food and wine matching is the perfect way to enhance the flavours of your meal, and while the people who get paid to do if for a living would have you think it’s a complex science, it’s actually not too hard to do. Here’s a simple seven-step guide to get you started as a food/wine-matching expert! 1. Sweet with heat – Wines that have a little bit of residual sugar (like a German Riesling) combine really well with spicy foods. This is because as the residual sugar enters your mouth it actually cools down spice in your food and creates a balance that allows you to savour the flavour. 2. Smoke with oak – When cooking foods that have been grilled or charred, you really want to be looking for a wine that has been aged in oak barrels. Oaked wines tend to be a little more intense, so they need to be matched with grilled/charred foods that can match and bring out the fruit flavours. 3. Match flavours and textures – Similar flavours and textures go well together, as you’d imagine. Just as rich foods suit rich wines, mild foods go well with mild wines and as a general rule when food and wine possess similar qualities they can complement each other and enhance common flavours. 4. Fats with acid and tannins – Wines that are high in acid (Sauvignon Blanc) or tannin (Cabernet Sauvignon) go well with fried or fatty foods and help round out the flavours in your mouth. It also acts as a palate cleanser and creates balance between the rich/oily foods and the wine. 5. Sweet with salt – As anyone who’s ever combined blue cheese with port would agree. The combination will bring out the fruity taste in sweet wine and the savoury taste in salty foods. So yeah, you’re completely justified with your pairing of a bottle of Moscato with a packet of Cheezels. 6. Sweet with sweet – But as anyone who’s had ice cream served with another variety of ice cream would agree two sweet things can make a very sweet thing. Sweet wines can help bring out the flavours in the food. Just take care to make sure the wine is sweeter than the food is. 7. If it grows together, it goes together – Hey, there’s a reason why you generally don’t have stein of lager with a bowl of risotto. Foods and wines of a particular ethnicity or region usually work together like clockwork and naturally have flavours and textures that work well in combination. Image credits: Getty Images

The happiness diet: 7 foods to boost your mood

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