This "Hybrid" Diet Doesn't Just Protect Your Heart, It's Slowing Brain Aging Too

Key Points:

• A study published in the Journal of Neurology Neurosurgery & Psychiatry found that greater adherence to the MIND diet, a hybrid of Mediterranean and DASH diets designed to protect brain health, is linked to slower decline in gray matter volume and reduced brain aging over a 12.3-year period.
• Higher MIND diet scores were also associated with slower expansion of lateral ventricular volume, indicating reduced brain tissue loss and delayed brain aging by about one year during follow-up.
• Key beneficial foods identified include berries and poultry, which help reduce oxidative stress and neuronal damage, while consumption of sweets and fast fried foods was linked to faster brain atrophy.
• Unexpectedly, higher whole grain intake correlated with unfavorable brain changes, and cheese intake showed protective associations despite being recommended for limitation on the MIND diet.
• The study’s limitations include potential unmeasured confounding, lack of genetic risk factor adjustment, and a primarily Caucasian study population, which may affect the generalizability of the findings.
