Do you drink coffee on a regular basis? Is your partner not really a fan of the drink? Then keep on reading. There might be a real reason why coffee could be beneficial to them, as it would help them with aging. Are you curious to know who discovered this and what the actual results are? Then keep on reading.
Coffee lovers might have one more reason to pour another cup. A massive 30-year Harvard study tracking nearly 50,000 women has found that moderate coffee consumption during midlife is linked to better odds of healthy aging.
More Coffee, Fewer Chronic Issues
The sweet spot? Around 315 milligrams of caffeine per day—the equivalent of about three small cups of coffee. Women who consistently drank this amount in their 40s and 50s were more likely to reach their 70s free from major illnesses, cognitive decline, or physical limitations.

The more they drank, the more benefits these people experienced. People with up to 5 cups daily would have the most benefits. However, it is only for caffeinated coffee. Drinking tea and decaf didn’t show any benefits. However, people who drank more caffeinated sodas such as cola saw a 20% to 26% drop in their chance of aging healthily. So maybe keep the sodas in the fridge and go for an iced espresso instead!
Association, Not Magic Bullet
While the results are encouraging for coffee fans, the researchers are clear: this is an association, not direct proof that coffee causes better health. The women who aged well also tended to follow other healthy habits, like regular exercise, balanced diets, and not smoking.
Still, the findings suggest that moderate caffeine from coffee could be a simple, enjoyable part of a healthy routine. For women entering midlife, that daily cup might do more than just wake you up.
