Antioxidants work in our body by slowing down or even preventing the oxidative process by neutralizing free radicals in our body. Free radicals are molecules produced when our body breaks down food, but we are also exposed to free radicals through oxygen and daily living such as exposure to tobacco smoke. Free radicals can damage our cells, antioxidants interact with free radicals and help with that damage. Consider antioxidants scavengers for free radicals, they go into our body and destroy the free radicals causing us harm. Anti oxidants are constantly being use by our bodies it is important to eat a well rounded diet as the anti oxidants used need to replenished because of the fact that as they attack they become oxidized themselves. Antioxidants are found in vitamins, minerals, and Beta carotene, so we are able to eat our way healthy providing ourselves with antioxidants on a daily basis.

Selenium is a trace mineral that functions as an antioxidant because of its antioxidant enzymes, it is also made up of selenoproteins, gluthathione peroxidase and thioredoxin reductase. Gluthathione peroxidase is important because it helps detoxify the body by reducing free radicals in the cell membrane. The main function of selenium is the prevention of oxidative stress and the body uses selenium to make antioxidant proteins...
