Antioxidants are compounds that inhibit oxidation(a chemical reaction that can produce free radicals that may damage the cells of organisms). Green tea, coffee, berries, and dark chocolate are renowned for being natural sources of antioxidants for the body. The antioxidants can be natural (such as ascorbic acid (AA, E300) and tocopherols (E306)) or synthetic( propyl gallate (PG, E310), tertiary butylhydroquinone (TBHQ), butylated hydroxytoluene (BHT, E321) and butylated hydroxyanisole (BHA, E320)). They are often used as food additives to help guard against food deterioration. The two main factors in the oxidation of food are exposed to oxygen and sunlight. Unsaturated fats in foods are particularly vulnerable to oxidation, causes them to turn rancid. Antioxidants are used to prevent foods from getting rancid, by stabilizing free radicals. There are dietary antioxidants as well that include vitamin A, vitamins C and E, selenium, lutein and quercetin. They also protect cells in the body from free radicals, reducing the risk of damage to the cells.
Antioxidants are available both as dietary supplements and food additive. Select according to your requirements. Check for the "use-by" date on their packaging.
