Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as âfree radical scavengers.â. The body makes some of the antioxidants it uses to neutralize free radicals. These antioxidants are called endogenous antioxidants. However, the body relies on external (exogenous) sources, primarily the diet, to obtain the rest of the antioxidants it needs.
Butylated hydroxyanisole â also known as BHA â is an antioxidant primarily used as a preservative in food, animal feed, cosmetics, rubber and petroleum products. The National Toxicology Program of the Department of Health and Human Services warns that BHA is âreasonably anticipated to be a human carcinogenâ (cancer-causing agent).
