Antioxidants are natural substances found mostly in fruits and vegetables. They act primarily in ridding the body of harmful toxins and oxygen byproducts called free radicals. When accumulated, free radicals can lead to massive cell damage, tissue damage, and even chronic and degenerative diseases such as cancer, heart disease, stroke, atherosclerosis, etc. The antioxidants you consume from your diet of fresh produce will help counteract the damage caused by free radicals.
