To better maintain your brain, think Mediterranean. Researchers reviewed data from two large National Institutes of Health studies with a total of 6,355 participants, nearly 10 percent with cognitive impairment. About 1 in 10 had diabetes. They compared what the participants reported eating with the results of standardized dementia tests administered at intervals for up to 10 years. After adjusting for dementia risk factors such as diabetes and age, they found that those who ate the most fruits, vegetables, whole grains, olive oil, fish, and other Mediterranean diet staples were 50 to 60 percent less likely to have cognitive impairment than those who ate the least. Participants who ate fish twice weekly showed slower cognitive decline. The study didn’t prove cause and effect, but it provides evidence that your diet affects your brain health.
