SELENIUM
A powerful antioxidant, especially when paired with vitamin E and zinc, selenium prevents the formation of free radicals in the body. Selenium is deeply involved in fat metabolism within the body, preventing the oxidation of fats and regulating the effects of thyroid hormone on fat metabolism. Studies revealed that men who took 200mcg of selenium daily for ten years had less chance of developing lung, prostate and colorectal cancer and that selenium may even boost the chances of survival in people with AIDS. Other functions of selenium in the body include assisting in pancreatic function and maintaining a healthy heart and liver.
