Coffee

Coffee is one of the most popular beverages in the world and the most abundant source of antioxidants in the American diet. Coffee, like most bitter foods, is high in polyphenols, which give the beverage its distinct flavor. Chlorogenic acid, one of the most common polyphenols in coffee, is a powerful antioxidant that is likely responsible for many of coffee's health advantages, including decreased oxidative damage and a lower risk of heart disease and diabetes.

According to studies, consuming 3-4 cups of coffee each day lowers your risk of mortality, cancer, and heart disease by 17%, 15%, and 18%, respectively, as compared to not drinking any coffee at all. A different study discovered that drinking one cup of coffee every day reduced your risk of type 2 diabetes by 7%. Caffeinated coffee may also protect against neurological illnesses such as Alzheimer's and Parkinson's disease, according to some studies, although more research is needed to determine why.
