Antioxidants In Supplements And Food
Antioxidants can come in the various forms of dietary supplements and are found in many fruits and vegetables. Eating a healthy diet with many fruits and vegetables can lower risks of certain diseases and kill cancer-causing free radicals. Some examples of antioxidants include vitamins A, C, and E, beta-carotene, lutein, lycopene, and selenium.
There has been much speculation as to whether or not there can be too many antioxidants in a diet. It is believed too high of levels of beta-carotene can increase the risk of lung cancer in smokers, and that too high of doses of vitamin E may increase the risk of prostate cancer.
