DASH Diet Emerges as Best Bet for Brain Health in Large Study
A large, multi‑cohort analysis from JAMA Neurology using data on nearly 160,000 adults found that following the DASH diet most closely was linked to the greatest reduction in cognitive decline risk (about 41% lower) compared with less adherent eaters; other healthy patterns also cut risk by 11–35%. A separate March 2026 study found greater adherence to the MIND diet (a DASH–Mediterranean blend) associated with slower brain aging and up to a 53% lower Alzheimer's risk. Experts note that midlife is a key window for prevention, and gradual dietary changes—more vegetables, fish, whole grains, and less sodium and sugar—along with exercise, can support long-term brain health.
