MIND Diet May Slow Brain Aging—Cheese Appears to Lend a Hand

A study of 1,647 adults over about 12 years found that closer adherence to the MIND diet (Mediterranean–DASH Diet) is linked to slower brain aging: every 3-point increase in the diet score corresponded to 20% less gray-matter loss (roughly 2.5 years of delay) and 8% less ventricular enlargement (about 1 year). Berries and poultry were key contributors; sweets and fried foods worsened hippocampal health. Unexpectedly, higher whole-grain intake was linked to faster decline, while higher cheese intake was associated with slower gray-matter and hippocampal loss and less ventricular enlargement—a notable exception to the diet’s usual limits. Benefits were stronger among older individuals, those who were physically active, and those not overweight, suggesting diet works with other healthy habits to protect brain structure.
