What the research found
Study (observational). Juliana Tavares, Monique Breteler and colleagues at DZNE report in Nature Communications (doi 10.1038/s41467-026-77064-4) on ~7,500 adults: 6,470 in the Rhineland Study (Bonn) plus 1,034 in EPIC-Potsdam. Adherence scores for ten patterns (including Mediterranean, Nordic, plant-based, DASH, and MIND) each associated with slower DNA-methylation clocks covering ~850,000 sites. More than 70% of affected pathways overlapped (cell structure, signaling, metabolism); DASH uniquely touched heart-related pathways and MIND cognition/memory pathways. Association, not a diet prescription or a dementia/CVD diagnosis. Educational aging notes.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
