“There is certainly much more good news than bad news, in terms of coffee and health,” says Frank Hu, MD, MPH, PhD, nutrition and epidemiology professor at the Harvard School of Public Health.
New research published after a 10-year study of more than 50,000 older women suggest that the risk for depression may decrease as coffee consumption increases. Those who drank 2-3 cups a day had a 15% decreased risk of depression compared to women who drank one cup a day or less.
“People have often worried that drinking caffeinated coffee might have a bad effect on their health, but there is more and more literature, including this study, showing that caffeine may not have the detrimental effect previously thought,” according to lead author Michel Lucas, PhD, RD, epidemiologist/nutritionist at Harvard School of Public Health in Boston.
The study is published in the September 26 issue of the Archives of Internal Medicine.
