The Mediterranean diet, touted for its ability to protect the heart aid longevity, now has another great outcome to recommend it: reducing the effects of aging on the brain.
Researchers followed nearly 3,800 men and women in their 60s or older, asking them to report what they ate and then measuring mental function.
Those who ate closest to the traditional Mediterranean diet — lots of fruits, vegetables, whole grains, beans, fish, olive oil and moderate amounts of wine — scored highest on their brain tests.
How this works isn’t clear, although researchers suspect it may be related to the diet’s known effects on the heart and circulation.
Better circulation would mean more oxygen and nutrients to the brain, helping it stay limber longer.
