A 1996 study conducted by researchers at the USDA and the University of Connecticut at Storrs shows that the antioxidant activity of both green and black tea was higher than many common fruits and vegetables, including broccoli, cauliflower, strawberries and garlic. What accounts for tea’s ability to fight free radicals? Researchers from Horticulture Research International say it’s polyphenols, a type of phytochemical. Within the polyphenol group are catechins (which act as antioxidants), from which theaflavins and thearubigins are produced during the manufacture of black tea. Theaflavins and thearubigins contribute to
