Selenium is an important trace mineral we need on a daily basis. It is essential to the proper functioning of the immune system and thyroid gland, and it is a powerful antioxidant.
It is obtained from plants, seafood and meat; however, the level of selenium in the diet is significantly affected by the nutrient level in the surrounding soil. People who live in selenium-poor regions may require supplementation.
Like other minerals, selenium is depleted during food processing and refining. Grains milled into refined flour lose most of their selenium when the bran and germ is removed. Other nutrients vanish as well.
