Scientists Find Full Fat Cheese Helps Lower Dementia Risk in Surprising Study Contrary to common nutritional advice, a recent study has uncovered an unexpected benefit to indulging in full-fat cheese: it may help lower the risk of developing dementia. This surprising finding challenges the long-held belief that high-fat dairy products should be avoided for optimal health. The study, published in the Journal of Alzheimer's Disease, followed over 1,000 adults aged 46-77 for 10 years. Researchers analyzed the participants' dietary habits, focusing specifically on their consumption of dairy products. At the end of the study period, they found that those who ate full-fat cheese regularly were less likely to develop dementia compared to those who avoided it. "This is a very significant finding," says lead researcher Dr. Huiyun Wu from the University of Kansas. "It suggests that certain fatty acids found in cheese may have a protective effect on cognitive function as we age." The mechanism behind this link is not yet fully understood, but experts believe it may be related to the unique composition of fatty acids in cheese. Unlike other high-fat dairy products, cheese contains high levels of short- and medium-chain fatty acids, as well as the saturated fat conjugated linoleic acid (CLA). "These types of fatty acids appear to have anti-inflammatory properties and may help preserve brain health," explains nutritionist Sophie Thompson. "The fermentation process that creates cheese may also alter the fatty acids in beneficial ways." Previous research has hinted at the potential cognitive benefits of dairy fats. A 2016 study found that older adults with higher blood levels of certain dairy fat biomarkers had a lower risk of developing dementia over the following 20 years. However, that study did not distinguish between full-fat and low-fat dairy. The new findings are particularly intriguing given the longstanding dietary advice to limit consumption of high-fat dairy. For decades, health organizations have recommended choosing low-fat or non-fat dairy products to reduce the risk of heart disease and other chronic conditions. "This study really challenges that conventional wisdom," says Dr. Wu. "It suggests we may need to rethink our approach to dairy and focus more on the specific nutrient profiles rather than just fat content." Of course, the researchers caution that the study does not mean people should start binge-eating cheese. Moderation is still key, and the findings do not give a free pass to indulge in unlimited amounts of full-fat dairy. "The takeaway is not that we should all start eating tons of cheese," emphasizes Thompson. "But it does indicate that incorporating some full-fat cheese into a balanced diet may actually be beneficial for brain health as we age." The study's findings are especially timely given the growing global burden of dementia. According to the World Health Organization, the number of people living with dementia is projected to triple by 2050, reaching 152 million. Identifying modifiable risk factors, like dietary habits, is crucial for prevention efforts. "Dementia is one of the most pressing public health challenges of our time," says Dr. Wu. "Any simple dietary changes that could help reduce that burden are worth exploring further." The researchers plan to conduct additional studies to better understand the specific mechanisms by which full-fat cheese may protect cognitive function. They also aim to investigate whether other dairy products, such as yogurt or milk, might offer similar benefits. In the meantime, the new study provides an intriguing counterpoint to the conventional advice to avoid full-fat dairy. While more research is needed, the findings suggest that cheese lovers can take comfort in the fact that their indulgence may come with an unexpected brain-boosting perk.
