A large study presented at the American Society for Nutrition meeting reveals that the MIND diet, combining Mediterranean and DASH diets, significantly reduces dementia risk, especially in older adults. Researchers found a 25% lower dementia risk for those improving MIND diet adherence over 10 years. While the study shows association, not causation, experts confirm the benefits of a Mediterranean-type diet for brain health, emphasizing diverse vegetable intake. The study included diverse ethnic groups, showing benefits across populations.
