It contributes to the structure and function of myelin sheathing, which insulates neural connections and acts as precursor to molecules that regulate inflammation and promote cell signalling.</p> <p>Scientists have long known that humans and other mammals can get palmitic acid from food or generate it in a process called de novo lipogenesis, which mainly requires glucose for its synthesis. Much less is known about which source the body relies on relative to diet and at different stages of growth and maturity.</p> <p>Bazinet said the study findings highlight the importance of palmitic acid for brain health at all stages, but especially during development, when need for the fat appears to be highest.</p> <p>鈥淚t鈥檚 interesting that although the brain can make palmitic acid, the liver up-regulated it so much. These systemic redundancies are built in, so the body won鈥檛 take a chance on not getting enough,鈥 said Bazinet, who is also a researcher at 茄子直播鈥檚&nbsp;<a href="https://childnutrition.utoronto.ca/">Joannah &amp; Brian Lawson Centre for Child Nutrition</a>.</p> <p>The results should give pause to manufacturers looking to reduce the amount of palmitic acid in infant formula, said&nbsp;<strong>Mackenzie Smith</strong>, first author on the study and a doctoral student in the Bazinet lab.</p> <p>鈥淚t鈥檚 possible that we can lower levels in formula, which could have a positive ecological impact, but we don鈥檛 yet know the potential health effects,鈥 Smith said. 鈥淎re there implications for behaviour or development when the liver produces so much? Might there be negative effects for the liver?鈥</p> <p>Smith also noted that even in mice that received the lowest amount of palmitic acid through diet, levels of the fat were still higher than those sought by some manufacturers of formula. That discrepancy adds to the rationale for further preclinical studies, as well as research in humans, Smith said.</p> <p>To uncover the source of palmitic acid in the brains of developing mice, the researchers applied a new carbon isotope technique. Isotopes are different versions of the same chemical element that vary slightly in mass; for their study, the researchers drew on natural differences in carbon isotope ratios in the environment, based on how plants absorb carbon in photosynthesis.</p> <p>鈥淢ost plants use the same path to fix carbon from the atmosphere and have the same carbon ratio, but sugars such as corn and sugar cane 鈥 which the liver uses to generate palmitic acid 鈥 have a different ratio,鈥 said Smith.</p> <p>In the brains of mice, a depleted carbon ratio signature indicated a dietary source of palmitic acid, Smith said, whereas an enriched signature suggested de novo lipogenesis.</p> <p>The researchers were able to track those signatures at many stages throughout mouse development, to determine the liver was the main source of palmitic acid in the developing brain 鈥 a finding they corroborated by looking at changes in genetics.</p> <p>The approach opens new research opportunities. 鈥淎s opposed to traditional radioactive tracers, which are very expensive, this new technique allows for a cost-effective and long-term study design,鈥 said Smith.</p> <p>Building on the current study鈥檚 findings, researchers in the Bazinet lab are now applying the same technique in tissue from adult human brains. The method could also provide a new way to measure and track the dietary sources of other fats and nutrients, Bazinet said.</p> <p>鈥淣utrition researchers often rely on people reporting their food intakes, which can lead to unreliable data,鈥 he added. 鈥淭hose problems could potentially be flagged with this kind of technology to track the source and amount of added sugars, for example. It could be very fruitful for nutritional science.鈥</p> <p>The research was supported by funding from the Natural Sciences and Engineering Research Council of Canada, the Canadian Institutes of Health Research and the Canada Research Chairs Program.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Mon, 22 Jan 2024 21:58:42 +0000 Christopher.Sorensen 305564 at GTA parents concerned about limited access to school food programs: Researchers /news/gta-parents-concerned-about-limited-access-school-food-programs-researchers <span class="field field--name-title field--type-string field--label-hidden">GTA parents concerned about limited access to school food programs: Researchers</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/2023-04/GettyImages-1396463199-crop.jpeg?h=f3f6fccf&amp;itok=PSAwV0sb 370w, /sites/default/files/styles/news_banner_740/public/2023-04/GettyImages-1396463199-crop.jpeg?h=f3f6fccf&amp;itok=EewkDqOX 740w, /sites/default/files/styles/news_banner_1110/public/2023-04/GettyImages-1396463199-crop.jpeg?h=f3f6fccf&amp;itok=n4QN7Lmb 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/2023-04/GettyImages-1396463199-crop.jpeg?h=f3f6fccf&amp;itok=PSAwV0sb" alt="Two children eating at a cafeteria."> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>Christopher.Sorensen</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2023-04-18T09:19:09-04:00" title="Tuesday, April 18, 2023 - 09:19" class="datetime">Tue, 04/18/2023 - 09:19</time> </span> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/jim-oldfield" hreflang="en">Jim Oldfield</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/our-community" hreflang="en">Our Community</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/joannah-brian-lawson-centre-child-nutrition" hreflang="en">Joannah &amp;

height: 250px; margin-left: 10px; margin-right: 10px; float: left;">The&nbsp;review,&nbsp;led by researchers at the University of Toronto and Harvard University,&nbsp;is the largest and most thorough analysis to date of research on sweetened drinks, and overweight and obesity 鈥 both of which heighten risks for diabetes, heart disease, some cancers and other diseases.</p> <p><strong>Vasanti Malik</strong>&nbsp;led the study&nbsp;鈥&nbsp;<a href="https://www.sciencedirect.com/science/article/pii/S0002916522105290">published in the&nbsp;<em>American Journal of Clinical Nutrition</em></a>&nbsp;鈥&nbsp;with colleagues in Toronto and Boston. Malik is an assistant professor of&nbsp;nutritional sciences&nbsp;at 茄子直播鈥檚 Temerty Faculty of Medicine and the&nbsp;Joannah &amp; Brian Lawson Centre for Child Nutrition.</p> <p>She recently spoke with writer&nbsp;<strong>Jim Oldfield</strong>&nbsp;about the findings&nbsp;and what they mean&nbsp;for public policy and personal health.</p> <hr> <p><strong>Why do this study now?</strong></p> <p>Our&nbsp;last meta-analysis&nbsp;on this topic was 2013. You want to update a meta-analysis every five to 10 years anyway, but especially in this area because there has been so much new research in the last decade. Evidence has continued to accumulate showing associations among sugar-sweetened beverages&nbsp;鈥 or SSBs, as we call them&nbsp;鈥 and weight and chronic disease. And it鈥檚 very important to have an updated synthesis of that evidence, especially for public policy. The&nbsp;<a href="https://food-guide.canada.ca/en/">Canada Food Guide</a>&nbsp;is clear on the need to limit SSBs and recommends water as the drink of choice&nbsp;鈥&nbsp;and added sugar intake, including SSBs, has declined in Canada,&nbsp;in part due to public policies. But levels here are still too high. As well, the USDA&nbsp;Dietary Guidelines for Americans&nbsp;are arguably not as strong&nbsp;鈥&nbsp;and with U.S. policymakers coming together soon to discuss the 2025 guidelines, our study will be an important piece of evidence to inform their work.</p> <p><strong>What did your study show?</strong></p> <p>We expected to find a positive association between SSBs and weight gain&nbsp;among adults and children, and in cohort studies and randomized clinical trials. And that was exactly what we found. We analyzed 85 studies, which totaled over half a million participants. In cohort studies, which follow people over long periods of time, each serving-per-day increase in SSBs was associated with a 0.42-kilogram&nbsp;(almost one pound) higher body weight in adults. In children, we saw a 0.07-unit higher body-mass index (just under one-twelfth of a BMI unit). Perhaps most striking, findings from our dose-response analysis showed that weight gain increases with increasing levels of SSB intake&nbsp;in both children and adults. A&nbsp;dose-response&nbsp;relationship provides&nbsp;strong&nbsp;evidence for a&nbsp;cause-and-effect&nbsp;relationship.&nbsp;</p> <p><strong>How much weight gain might one drink per day lead to over time?</strong></p> <p>We estimated the associated change in body weight over a one-year period. For adults, one additional 12-ounce serving per day was linked to a 0.20-kg higher body weight (about half a pound) in one year. Over 10 years, that could be about five pounds. In children, we observed a 0.03-unit higher BMI for each additional daily serving of SSBs over a one-year period. Although these results may seem modest, weight gain is a gradual process, with adults averaging about one pound (0.45 kg) of weight gain per year. So, limiting SSB consumption could be an effective way to prevent age-related weight gain. Limiting SSB intake among children is also an important strategy to help them develop healthy lifestyle habits and weight trajectories.</p> <p><strong>How common is excess consumption of these drinks?</strong></p> <p>It鈥檚 very common. Sugar-sweetened beverages include sodas, fruit drinks, sports and energy drinks, and they are the largest source of added sugar in the North American diet. Moreover, the rise in consumption of these drinks has mirrored the epidemic of overweight and obesity. In 2016, almost two billion adults were estimated as overweight and 650 million had obesity. Even more worrying, the rate of increase in obesity in children and adolescents is now greater than in adults. The prevalence of childhood obesity has increased more than four-fold globally since the 1970s, which is truly alarming.</p> <p><strong>What are some of the health effects of SSBs?</strong></p> <p>A typical 12-ounce serving of an SSB contains over 140 calories and more than eight teaspoons of sugar. That nearly reaches the recommended daily limit for added sugar, which is no more than 10 per cent of total calories, or about 200 calories for a 2000-calorie per day diet. These drinks are sugar in liquid form. They鈥檙e usually made with table sugar, high-fructose corn syrup or other sweeteners that provide calories&nbsp;and are digested rapidly&nbsp;鈥 more so than sugar consumed as a solid. This bolus of glucose increases blood sugar levels, which triggers a glycemic response that over time can lead to insulin resistance and diabetes. The fructose component also floods the liver, which can cause lipogenesis (creation of fat), that puts a person on the path to fatty liver and metabolic disease. Fructose also increases uric acid, which contributes to insulin resistance and risk for cardiovascular and other diseases. Insulin spikes from the glycemic response can result in an appetite cascade and over-eating, as can excess insulin in the blood over longer periods. Some evidence shows that SSBs activate the dopaminergic reward system in the brain and encourage addictive behaviour&nbsp;and that they alter the gut microbiome&nbsp;鈥 but we need more research on those effects.</p> <p><strong>Are you optimistic, given these effects and the research evidence? &nbsp;</strong></p> <p>Intake levels of SSBs have come down in the developed world. We鈥檙e still seeing increases in the developing world, but taxes in some of those countries are working. Thailand introduced a tax that has reduced consumption, as has Mexico and South Africa. At least 85 countries now have a tax on SSBs, which in part reflects the&nbsp;World Health Organization鈥檚 stand on this issue. In Canada, Newfoundland introduced a tax recently&nbsp;and several U.S. regions and cities have had a tax for years&nbsp;in response to&nbsp;public health efforts, more awareness and advocacy. The general effect of these taxes is reduced intake&nbsp;and the revenues can be put toward further public health measures and health care. Other changes will help in Canada and elsewhere as well, such as limiting marketing to children&nbsp;and better front-of-pack and nutrition labels. All these efforts will push intake down, but it鈥檚 important to remember that people need access to clean, safe drinking water as an alternative. That鈥檚 an ongoing challenge globally&nbsp;and in many parts of Canada&nbsp;that we really need to address.</p> <p><em>Malik holds a Canada Research Chair in Nutrition and Chronic Disease Prevention at 茄子直播&nbsp;and an adjunct faculty position in nutrition at the Harvard T.H.

Brian Lawson Centre for Child Nutrition</a>,&nbsp;and includes a review of all breakfast, lunch and snack programs in Canadian schools, along with their impact on children鈥檚 academic achievement and health.</p> <p>The work began last summer under Ahmed鈥檚 guidance, with the hire of two nutritional sciences undergraduate students. The students reviewed existing monitoring and assessment tools for school food programs and environments, as well as news and other reports on the impact of COVID-19 on program delivery.</p> <p>The team worked closely with Lawson Centre scientists&nbsp;<strong>Daniel Sellen</strong>, who also has cross appointments in the department of anthropology in the Faculty of Arts &amp; Science and at the Dalla Lana School of Public Health,&nbsp;<strong>Zulfiqar Bhutta</strong>, who is also&nbsp;co-director and director of research at the Hospital for Sick Children's Centre for Global Child Health, and public health researcher&nbsp;<strong>Vasanti Malik</strong>&nbsp;and others. They will begin to share their results this year. Their findings will be critical to the design and delivery of Canadian school food programs, and will include equity indicators such as race and income.</p> <p>School food programs in Canada vary greatly in terms of who delivers them, which children they reach and what鈥檚 on the menu. Many advocates including the&nbsp;<a href="https://www.healthyschoolfood.ca/">Coalition for Healthy School Food</a>&nbsp;have said for years that heterogeneity hinders effective and broad program delivery.</p> <p>Canada is the only G7 nation without a national school food program, although the federal government committed to develop a policy on the issue in its 2022 budget.</p> <p>Other countries have put in place or are developing national programs with various areas of focus, and Ahmed says their experiences should prove useful for Canada. She recently joined&nbsp;INFORMAS, an international network for food and obesity researchers, and the global&nbsp;<a href="https://schoolmealscoalition.org/" target="_blank">School Meals Coalition</a>, in part to tap learnings from across Canada and abroad, and to leverage existing findings.</p> <p>One early insight from interaction with those groups was that researchers have developed new equity indicators to track how programs work for under-privileged students, especially in Brazil and other Latin American countries, Ahmed says.</p> <p>鈥淐apturing established and emerging program assessment tools is a complex undertaking,鈥 Ahmed says. 鈥淲e didn鈥檛 realize how vast it would become, which is challenging, but it has also afforded some great opportunities for two-way learning and collaboration.鈥</p> <p>Longer-term, Feeding Kids, Nourishing Minds will enable the researchers to design and test school-level interventions to improve meal program delivery. The project will run over four years.</p> <p>鈥淕iven that Canada is so culturally diverse and geographically vast, we鈥檒l likely need to take the best elements of programs in Canada and adapt approaches from around the world&nbsp;if we want an effective strategy for feeding children well in our schools,鈥 Ahmed says. 鈥淚鈥檓 excited about how that could look.鈥</p> <p>Feeding Kids, Nourishing Minds is funded by a $2-million investment from&nbsp;<a href="https://www.pcchildrenscharity.ca/">President鈥檚 Choice Children鈥檚 Charity</a>, and by the Joannah &amp; Brian Lawson Centre for Child Nutrition at the University of Toronto.</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 29 Apr 2022 16:19:37 +0000 Christopher.Sorensen 174381 at How effective are school food programs? 茄子直播 researchers launch nationwide study /news/how-effective-are-school-food-programs-u-t-researchers-launch-nationwide-study <span class="field field--name-title field--type-string field--label-hidden">How effective are school food programs? 茄子直播 researchers launch nationwide study</span> <div class="field field--name-field-featured-picture field--type-image field--label-hidden field__item"> <img loading="eager" srcset="/sites/default/files/styles/news_banner_370/public/Photo-by-Siarhei-Shuntsikau%2C-Dreamstime-crop.jpg?h=afdc3185&amp;itok=VZjd5jzh 370w, /sites/default/files/styles/news_banner_740/public/Photo-by-Siarhei-Shuntsikau%2C-Dreamstime-crop.jpg?h=afdc3185&amp;itok=N8ks7PD_ 740w, /sites/default/files/styles/news_banner_1110/public/Photo-by-Siarhei-Shuntsikau%2C-Dreamstime-crop.jpg?h=afdc3185&amp;itok=boV_yUSc 1110w" sizes="(min-width:1200px) 1110px, (max-width: 1199px) 80vw, (max-width: 767px) 90vw, (max-width: 575px) 95vw" width="740" height="494" src="/sites/default/files/styles/news_banner_370/public/Photo-by-Siarhei-Shuntsikau%2C-Dreamstime-crop.jpg?h=afdc3185&amp;itok=VZjd5jzh" alt="two young children sit outside to eat their lunch"> </div> <span class="field field--name-uid field--type-entity-reference field--label-hidden"><span>lanthierj</span></span> <span class="field field--name-created field--type-created field--label-hidden"><time datetime="2021-12-10T06:50:38-05:00" title="Friday, December 10, 2021 - 06:50" class="datetime">Fri, 12/10/2021 - 06:50</time> </span> <div class="clearfix text-formatted field field--name-field-cutline-long field--type-text-long field--label-above"> <div class="field__label">Cutline</div> <div class="field__item"><p>(Photo by Siarhei Shuntsikau/Dreamstime)</p> </div> </div> <div class="field field--name-field-author-reporters field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/authors-reporters/jim-oldfield" hreflang="en">Jim Oldfield</a></div> </div> <div class="field field--name-field-topic field--type-entity-reference field--label-above"> <div class="field__label">Topic</div> <div class="field__item"><a href="/news/topics/breaking-research" hreflang="en">Breaking Research</a></div> </div> <div class="field field--name-field-story-tags field--type-entity-reference field--label-hidden field__items"> <div class="field__item"><a href="/news/tags/temerty-faculty-medicine" hreflang="en">Temerty Faculty of Medicine</a></div> <div class="field__item"><a href="/news/tags/joannah-brian-lawson-centre-child-nutrition" hreflang="en">Joannah &amp; Brian Lawson Centre for Child Nutrition</a></div> <div class="field__item"><a href="/news/tags/child-development" hreflang="en">Child Development</a></div> <div class="field__item"><a href="/news/tags/child-health" hreflang="en">Child Health</a></div> <div class="field__item"><a href="/news/tags/dalla-lana-school-public-health" hreflang="en">Dalla Lana School of Public Health</a></div> <div class="field__item"><a href="/news/tags/research-innovation" hreflang="en">Research &amp; Innovation</a></div> <div class="field__item"><a href="/news/tags/st-michael-s-hospital" hreflang="en">St. Michael's Hospital</a></div> </div> <div class="clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item"><p>Researchers at the University of Toronto have begun studying school-based meal programs across Canada&nbsp;to better understand which programs work well, how they have functioned during the COVID-19 pandemic 鈥 and whether a long-discussed national program could improve child nutrition in this country.</p> <p>School food programs in Canada number in the thousands, reaching&nbsp;<a href="https://canadianfoodstudies.uwaterloo.ca/index.php/cfs/article/view/483">an estimated one-fifth</a> of the country's five million students.

We need to answer these questions,鈥 Maximova says.</p> <p>Further concerns include which foods should be on the menu and how to source them, and how best to monitor and regulate a program to national standards.</p> <p>The new study will address these and other issues over a four-year span, and will include researchers from medicine, public health, social work, engineering, humanities and early child development.</p> <p>The researchers will begin to share findings in 2022, including a planned review of all Canadian programs with information on school meal program format and nutritional quality, and the ages, socioeconomic and health status of children served.</p> <p>Later phases of the study will employ workshops and consultations with local educators, school nutritionists and public health units, followed by trials, cohort studies and a national knowledge-sharing campaign.</p> <p>The need for better data and a more effective approach to school food programs across Canada is pressing.</p> <p>Pre-pandemic studies showed that <a href="https://www150.statcan.gc.ca/n1/pub/82-620-m/82-620-m2006002-eng.htm">fewer than one-third</a> of Canadian children consumed enough fruits and vegetables, and that <a href="https://www.canada.ca/en/public-health/services/publications/healthy-living/obesity-excess-weight-rates-canadian-children.html">almost one-third</a> were overweight or obese. Global research has long <a href="https://pubmed.ncbi.nlm.nih.gov/16014126/">linked child diets to academic performance</a> and health, and shown that school food programs such as breakfasts, lunches and snacks can be effective interventions.</p> <p>In the first few months of the pandemic, Statistics Canada reported a <a href="https://www150.statcan.gc.ca/n1/pub/45-28-0001/2020001/article/00039-eng.htm">jump in food insecurity</a>, or the inadequate access to affordable and nutritious food, from 12.7 to 14.6 per cent of households.

Likewise, parents of children with more body fat might have chosen lower-fat milk to reduce the risk of obesity.</p> <p>Still, researchers have proposed several mechanisms that might explain a causal relationship between higher-fat milk and reduced obesity, such as increased satiety that leads to less overall consumption. It may also be that lower satiety from reduced-fat milk results in greater milk consumption and therefore higher weight gain.</p> <p>Maguire and his colleagues next plan to study the potential cause and effect between whole milk and lower risk of obesity in a randomized controlled trial, called the Cow鈥檚 Milk Fat Obesity Prevention Trial (COMFORT). The researchers will follow two groups of children 鈥 from the age of two&nbsp;鈥&nbsp;for two years, with one group on whole milk and the other on reduced-fat milk.</p> <p>鈥淲e鈥檙e making progress on the issue of which milk is best for children, but a randomized controlled trial will give us much more clarity on the outstanding questions,鈥 said Maguire.</p> <p>The research was supported by the Canadian Institutes of Health Research, among others.&nbsp;</p> <p><em>With a file by Jennifer Stranges at St. Michael鈥檚 Hospital, Unity Health Toronto</em></p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Thu, 09 Jan 2020 16:54:32 +0000 Christopher.Sorensen 161637 at
