Image credit: Ingrid Bertens\/Stocksy<\/p>\n<ul>\n<li><strong>A study finds that eating eggs is associated with a reduced risk of developing Alzheimer\u2019s disease.<\/strong><\/li>\n<li><strong>Using brain autopsies, the scientists also showed that those who ate eggs more regularly had less protein buildup in the brain associated with Alzheimer\u2019s.<\/strong><\/li>\n<li><strong>The researchers conclude that this link may be due to eggs\u2019 choline and omega-3 content.<\/strong><\/li>\n<\/ul>\n<p>Eggs have been a dietary staple since before humans evolved to be humans. Although they are packed with nutrients, relatively cost-effective, and easy to source, they have been the subject of much controversy in the health and wellness domain over the years.<\/p>\n<p><strong>According to the authors, eating one egg per week was associated with a 47% reduction in Alzheimer\u2019s risk compared with eating eggs less than once each month. <\/strong><\/p>\n<p>They also showed that those eating eggs had a reduced buildup of the toxic proteins associated with Alzheimer\u2019s.<\/p>\n<p>Before we get into the details, we should mention that some of the authors received funding from the <a href=\"https:\/\/www.incredibleegg.org\/about-us\/egg-nutrition-center\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Egg Nutrition Center<\/a>, \u201cthe science and nutrition education division of the American Egg Board.\u201d<\/p>\n<p>Are eggs good for you or bad for you? One hundred years ago, and for thousands of years before that, eggs were considered essential. Nutrient-dense and rich in protein and micronutrients, eggs were a staple throughout the world.<\/p>\n<p><strong>However, as nutrition science progressed, it became clear that <a href=\"https:\/\/academic.oup.com\/ajcn\/article\/102\/2\/276\/4564504\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">dietary cholesterol<\/a> did not significantly impact blood levels of cholesterol.<\/strong><\/p>\n<p>Thanks to this new understanding, and a healthy dose of research funding from the Egg Nutrition Center, eggs were edged slowly back into play.<\/p>\n<p>Their saturated fat content, though, is still a concern, so eggs are still partially sidelined. Still, they are likely much healthier than many of the low-fat, highly processed snacks that have replaced eggs in modern kitchens. In fact, <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6470839\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">eggs contain all essential trace elements<\/a>.<\/p>\n<p>Today, most nutritionists and associated experts have a relatively neutral view of eggs. In general, the advice is that they can form a part of a healthy, well-balanced diet, but at the same time, eating multiple eggs per day could be unhealthy.<\/p>\n<p>Alzheimer\u2019s is the most common form of dementia, and despite decades of research, there is no cure, and treatments that can slow the disease are severely lacking.<\/p>\n<p>For that reason, understanding the lifestyle factors associated with increased risk is essential. In this vein, many scientists are focusing on dietary influences.<\/p>\n<p><strong>Previous research has shown that choline is <a href=\"https:\/\/www.nature.com\/articles\/nrn1588\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">important for cognitive function<\/a>. It has also identified a potential link between moderate choline intake and a <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S0002916524008694\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">reduced risk of dementia<\/a>. As the authors of the latest study explain, eggs are the \u201ctop food source\u201d of choline, so they are worth investigating. <\/strong><\/p>\n<p>Choline has many important functions; for instance, it is a precursor to the neurotransmitter acetylcholine, plays a pivotal role in cell membranes, and has <a href=\"https:\/\/www.mdpi.com\/2072-6643\/9\/8\/815\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">neuroprotective powers<\/a>. <\/p>\n<p>Also, as the authors explain, \u201ccholine modulates the expression of key genes related to memory, learning, and cognitive functions via epigenetic mechanisms.\u201d<\/p>\n<p>Although our body can synthesise choline, it <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC2782876\/\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">cannot synthesize enough<\/a> to meet all the body\u2019s needs, so some must be taken in with our diet. <\/p>\n<p>These facts led the authors of the new study to investigate links between egg consumption and Alzheimer\u2019s risk.<\/p>\n<p>The recent study included data from 1,024 older adults with an average age of 81.4. All participants lived in retirement communities and residential facilities in Illinois. <\/p>\n<p>They attended yearly checkups and completed food frequency questionnaires, and the researchers followed them for an average of 6.7 years. <\/p>\n<p>During this time, a little over one-quarter of them developed Alzheimer\u2019s disease.<\/p>\n<p><strong>After analysis, the scientists found that individuals who consumed at least one egg per week had a 47% reduced risk of developing Alzheimer\u2019s during follow-up compared with those eating one egg per month or fewer.<\/strong><\/p>\n<p>In the second part of their study, they looked at the post-mortem brains of 578 participants. They found that those who ate one or more eggs each week were more likely to have less Alzheimer\u2019s-associated protein buildup.<\/p>\n<p>Overall, the authors suggest that consuming at least one egg per week may help reduce the risk of Alzheimer\u2019s. They explain that the choline and omega-3s in eggs might have a \u201csynergistic\u201d effect, whereby they join forces to protect brain health during aging.<\/p>\n<p>Medical News Today spoke to <a href=\"https:\/\/www.michaeljfox.org\/researcher\/christopher-u-missling-phd-mba\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">Christopher U. Missling<\/a>, PhD, president and CEO of Anavex Life Sciences, who was not involved in the study. Missling explained that:<\/p>\n<blockquote class=\"is-layout-flow wp-block-quote-is-layout-flow css-34gtoi\">\n<p>\u201cAbout 39\u201340% of the protective effect was explained by higher dietary choline intake. Egg yolks also contain omega-3 fatty acids, which have known neuroprotective properties. The combination of choline and omega-3s may be particularly beneficial for brain health.\u201d<\/p>\n<\/blockquote>\n<p>The study authors also point to <a href=\"https:\/\/link.springer.com\/article\/10.1007\/s40120-020-00227-y\" target=\"_blank\" rel=\"noopener noreferrer nofollow\" class=\"content-link css-90fpmc\">previous research<\/a> demonstrating that people with Alzheimer\u2019s are more likely to be deficient in omega-3s and choline.<\/p>\n<p>Overall, the scientists conclude that, \u201conce replicated in other prospective cohorts and confirmed by clinical trials, these findings may have important public health implications for reducing the population\u2019s risk of [Alzheimer\u2019s].\u201d<\/p>\n<p>If the results are replicated, this could be a very useful, low-cost intervention. MNT also spokle with Maddie Gallivan, RD, a registered dietitian who was likewise not involved in the recent study.<\/p>\n<p>\u201cEggs are often a go-to food for older adults, as they\u2019re soft in texture, which can be helpful for those with dentures, quick to prepare, and packed with key nutrients,\u201d Gallivan explained. \u201cSo it\u2019s great to see a study focussing on how they may support cognitive health in later life.\u201d<\/p>\n<p>However, the study does have certain limitations. For instance, they only had a relatively short follow-up \u2014 just 6.7 years. This, as the authors explain, increases the risk of reverse causality. <\/p>\n<p>\u201cThe study population consisted of older adults from the Rush Memory and Aging Project, a specific U.S.-based cohort,\u201d Missling told MNT. \u201cThe findings may not generalize to younger populations or those from different cultural or dietary backgrounds.\u201d<\/p>\n<p>He also reminded us that \u201cdietary intake was assessed through self-reported food frequency questionnaires, which are subject to recall bias and inaccuracies.\u201d So, participants may not have accurately reported or remembered their egg consumption.<\/p>\n<p><strong>\u201cIt\u2019s important to remember that no single food acts in isolation,\u201d Gallivan told us, \u201cand it\u2019s our overall dietary pattern that really counts. A varied, nutrient-dense diet rich in whole foods is key to supporting brain health and reducing dementia risk.\u201d<\/strong><\/p>\n<p>For now, if you like eggs, enjoy them. They may reduce your dementia risk, but if not, they will certainly provide you with a good dose of protein and a healthy range of micronutrients.<\/p>\n","protected":false},"excerpt":{"rendered":"Share on PinterestEating eggs regularly is linked to less buildup of toxic proteins in brain, according to a&hellip;\n","protected":false},"author":3,"featured_media":78173,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[10263,632,815,1182,159,67,132,68],"class_list":{"0":"post-78172","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-genetics","8":"tag-alzheimers-disease","9":"tag-dementia","10":"tag-genetics","11":"tag-nutrition","12":"tag-science","13":"tag-united-states","14":"tag-unitedstates","15":"tag-us"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@us\/114885989791154152","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/78172","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/comments?post=78172"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/posts\/78172\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media\/78173"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/media?parent=78172"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/categories?post=78172"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/us\/wp-json\/wp\/v2\/tags?post=78172"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
