antioxidant

Free radical fighter

An antioxidant is a substance that prevents or slows damage caused by oxidation—the chemical process that degrades materials exposed to oxygen.

In nutrition, antioxidants like vitamins C and E are credited with neutralizing harmful compounds in the body: Blueberries are rich in antioxidants.

The term appears constantly in health marketing, often with exaggerated claims.
