Antioxidants
Coffee is the number one source of antioxidants in the U.S., according to researchers at the University of Scranton.
Joe Vinson, Ph.D., lead author of the study, said that "Americans get more of their antioxidants from coffee than any other dietary source. Nothing else comes close."2
The authors of the study emphasize moderation, stating that only one or two cups a day appear to be beneficial.
Caffeinated and decaffeinated versions provided nearly the same levels of antioxidants.
