MIND Diet Linked to About 2.5-Year Slowing of Brain Aging

A large observational study found that adherence to the MIND diet—an blend of Mediterranean and DASH principles focused on brain-healthy foods like berries, leafy greens, fish, poultry, whole grains, olive oil, and nuts—was associated with slower brain aging over about 12 years, including reduced gray-matter loss and slower enlargement of brain ventricles, equating to roughly a 2.5-year delay. The effect appears tied to overall dietary pattern rather than a single food, but causation can’t be proven.
