Antioxidants are vitamins that prevent oxidations of cells and prevent cell damage due to free radicals in the body. Free radicals are often attributed to aging of cells and increased susceptibility to disease. Sources of free radicals include sunlight, smoking and drinking alcohol according to Medical News Today. Antioxidants are found in vitamins C and E, carotenoid (yellow/ orange pigments), flavonoid (Red foods like berries and red cabbage) , Phenol (found in many fruits), and liganin (Whole grains and legumes) according to Mayo Clinic. Although that may sound like a lot of chemicals, keep in mind that chemicals make up everything around you good or bad.
