Mind Diet Linked to Slower Biological Aging and Broad Brain-Health Benefits

A UK Biobank study of about 170,000 adults over a median of ten years found that high adherence to the MIND diet—rich in leafy greens, berries, nuts, whole grains, and fish—was linked to lower risk of dementia and stroke and fewer depression and anxiety symptoms, along with slower biological aging and preserved brain volumes; in contrast, high intake of ultra-processed foods predicted higher risks for dementia, depression, anxiety, and Parkinson's disease. The findings were validated in American and Chinese cohorts, and potential pathways include improved metabolism and aging biomarkers (e.g., GDF-15). Mendelian randomization suggested possible causality, but the study remains observational and randomized trials are needed.
