The idea that the world’s second most popular beverage could be a health drink isn’t so far-fetched. Tea is rich in flavonoids, a family of compounds that gives plants some of their most vibrant hues. In theory, flavonoids help protect you against a host of chronic diseases. In lab tests, flavonoids keep blood platelets from clumping. This could help prevent the formation of clots that trigger heart attacks and strokes. Flavonoids are also powerful antioxidants, capable of guarding cells and molecules from the ravages of oxygen free radicals.
