A recent study found women who drank a cup or more of coffee daily had a 25-percent lower risk of stroke, compared to those who didn't.
Doctors say the study doesn't prove coffee reduces stroke risk, only that coffee drinkers tend to have a lower stroke risk, and it's not clear why.
The study followed about 35,000 women for 10 years.
Results of the study were published online in this week's edition of the American Heart Association's Journal.
