What if that daily cup of coffee wasn’t just a caffeine kick but a habit that actually supports healthy aging?
A new 30‑year Harvard study, following nearly 50,000 women, suggests that moderate amounts of caffeinated coffee are linked with stronger brains and bodies even past age 70.
The Long Brew: What the Study Found

- By 2016, 3,706 women made it into the “healthy agers” category — meaning they reached 70+ without major chronic illness, while keeping their physical and mental faculties strong.
- Each cup of caffeinated coffee (about 80 mg caffeine) added a 2–5% greater chance of healthy aging — up to about five cups daily
- No similar association was found with tea, decaf, or soda — in fact, cola intake was tied to a 20–26% lower chance of healthy aging.
