Not All Antioxidants Are Created Equal, Or Beneficial, Study Finds

It is generally believed that antioxidants block the harmful effects of omega-6 on DNA. One antioxidant – green tea polyphenol – does have that effect, reducing the formation of a liver cell structure that links a chemical to DNA and may cause mutations, according to a U.S. study in animals. But the U.S. study also shows that the antioxidant vitamin E actually increases damage caused by omega-6 fatty acids, which are found in many cooking oils.
