A long‑term study of nearly 50,000 women from the Nurses’ Health Study found that midlife consumption of caffeinated coffee (about three small cups daily) was linked to a 2–5% higher chance of healthy aging per cup, including physical resilience, mental well‑being, and cognitive function. Notably, decaf, tea showed no benefits, and cola intake was associated with a 20–26% lower likelihood of aging well, suggesting that regular coffee may uniquely support healthier aging trajectories.
