The tea polyphenols have been reported in various research to exhibit antioxidant properties. Antioxidants have been touted as having a range of health benefits, but the scientific evidence for these is still a little vague in parts. Studies have shown that antioxidants can protect cells from damage as a result of free radicals – molecules with an unpaired electron – but the results of some longer term trials have been inconclusive as to their efficacy, particularly in cancer treatments. Meanwhile, other studies have indicated an inverse relationship between tea consumption and cardiovascular disease.
