Selenium activates an antioxidant enzyme called glutathione peroxidase, which may protect the body from cancer. A recent double-blind study following over 1,300 people found that those given 200 mcg of yeast-based selenium per day for seven years had a 50% drop in the cancer death rate compared with the placebo group. Selenium is also needed to activate thyroid hormones. Where is it found? Brazil nuts are the best source of selenium. Yeast, whole grains, and seafood are also good sources.
