Green tea contains potent antioxidant catechins and polyphenols that help prevent inflammation, cancer, heart disease and other chronic diseases. Now research reports that a green tea polyphenol extract may one of the most powerful free radical scavengers. It found that the extract can help protect cells from DNA induced radiation damage. Antioxidants such as those found in green tea neutralize harmful free radicals (toxic byproducts of metabolic functions) and protect against oxidative damage.
