A new study of nearly 50,000 women followed over 30 years found that drinking caffeinated coffee in midlife may help women age in a healthier way.
Women who drank regular coffee were more likely to stay physically and mentally healthy into old age. These women were less likely to suffer from major diseases, memory loss, or physical decline.
The study included women from the long-term Nurses’ Health Study. Researchers tracked their health and lifestyle habits since 1984.
Healthy aging was defined as living past 70 without major diseases, and with good memory, physical ability, and mental health.
Women who drank more caffeinated coffee—up to 5 small cups a day—were 2% to 5% more likely to age healthily. Tea and decaf coffee did not show the same benefits.
Drinking cola, even though it contains caffeine, was actually linked to worse aging outcomes. Each glass of cola was linked to a 20% to 26% lower chance of healthy aging.
Researchers say that while coffee may help, it’s not a magic solution. The best results come when moderate coffee drinking is combined with a healthy lifestyle: eating well, exercising, and avoiding smoking.
The study’s authors also warn that more caffeine isn’t always better. Everyone’s body is different, and genetic differences may affect how caffeine impacts health.
Future research will look at the specific ingredients in coffee that might help with aging, especially in women. This could lead to more personalized diet advice for staying healthy as we grow older.
