A recent Harvard study of over 47,500 women found that those who drank one or more cups of coffee a day were statistically more likely to be among the healthy agers – individuals aged 70 and older with good mental and physical health. The research, led by post-doctoral fellow Sara Mahdavi, analyzed data from the Nurses’ Health Study over three decades.
For every additional cup of coffee consumed daily, women’s likelihood of being a “healthy ager” increased between 2% to 5%. Caffeinated coffee had no impact on healthy aging, while decaffeinated coffee and tea did not have significant associations. Drinking soda was associated with a lower likelihood of healthy aging.
The study controlled for various factors such as age, BMI, smoking, alcohol consumption, physical activity, education, and dietary protein. While the findings show correlation rather than causation, they align with previous research linking coffee to positive health effects. The Harvard study adds to a growing body of evidence supporting moderate coffee consumption as part of healthy aging.
