MIND Diet Slows Brain Aging by 2.5 Years

Adhering to the MIND diet, a combination of Mediterranean and DASH eating principles, has been shown to slow structural brain aging by more than two years. This specialized diet emphasizes brain-healthy foods such as berries, beans, leafy greens, fish, poultry, whole grains, olive oil, and nuts, while limiting saturated fats.

Research analyzing over 1,600 adults found that closer adherence to the MIND diet was associated with a 20% slower loss of gray matter, correlating to a 2.5-year delay in brain aging. Furthermore, participants who followed the diet more strictly experienced an 8% slower enlargement of brain ventricles for every three-point increase in adherence.

This slower ventricle enlargement, which tends to accelerate with age, is linked to a reduction in brain atrophy. While the study is observational, experts suggest a plausible causal pathway where healthy eating positively impacts brain structure and function. Berries and poultry were particularly noted for their antiaging benefits on the brain.
