MIND Diet Linked to 20% Slower Grey Matter Loss Over 12 Years in 1,647 Adults

{"The team followed 1,647 adults averaging age 60 at baseline, using repeated food-frequency questionnaires from 1991–2001 and serial MRI scans from 1999–2019. Participants showed no stroke or dementia at first scan. Higher MIND scores correlated with slower ventricular expansion and grey-matter preservation after adjusting for education, smoking, diabetes, and cardiovascular disease.","Berries and poultry drove the strongest protective signals, while sweets and fried foods accelerated atrophy. These patterns align with earlier MIND-diet trials showing cognitive benefits and extend them to measurable structural change, suggesting diet may modify trajectories relevant to Alzheimer’s and vascular dementia risk.","The observational design leaves residual confounding possible; randomized controlled trials with longitudinal imaging are needed to confirm causality. Replication in more diverse cohorts and integration with biomarker data would strengthen causal claims and guide public-health recommendations for age-related cognitive decline.","If confirmed, the MIND pattern offers a scalable, low-risk intervention amid rising global dementia prevalence, potentially delaying structural brain aging by years at population scale."}
