Participants (n = 22,495) were classified as abstainers, former drinkers, moderate drinkers according to national guidelines (≤250 mL/d men; ≤125 mL/d women) or Mediterranean Diet (MD) (125–500 mL/d men; 62.5–250 mL/d women), and heavy drinkers (>500 mL/d men; >250 mL/d women). Biological age (BA) was estimated with a deep neural network using 36 circulating biomarkers, and Δage (BA–chronological age) served as an index of biological aging.ResultsIn men, wine consumption, at doses defined moderate by a current MD Score, was associated with slower biological aging (Δage β = −0.39; 95%CI: −0.78, −0.01 vs. abstainers). Dose–response analyses showed a J-shaped curve, with the slowest Δage at ∼170 mL/d (Δage = −0.34 years; 95%CI: −0.66, −0.03). Overall ethanol intake, including all alcoholic beverages consumed, was neutral at moderate levels and associated with faster biological aging at higher doses.ConclusionModerate wine consumption, but not overall ethanol intake, may contribute to slower biological aging in men.
