What's not so clear, the NCCIH reports, is whether that link is attributed directly to the antioxidant content of those foods, or to the vitamin and mineral content or some other component of these foods. That's a lot of letter jumble, but all you really need to know is that there are hundreds - and possibly thousands - of types of antioxidants.Īccording to the National Center for Complementary and Integrative Health, science to date clearly shows that eating a diet high in antioxidant-rich foods can promote good health and assist in the fight against chronic diseases. There are several families of antioxidants, including vitamins, carotenoids, terpenes, alkaloids, minerals, flavonoids, curcumins, catechins, tannins, anthocyanins, lignans, glucosides and more. You may already be familiar with some antioxidants, including vitamin C and vitamin E, as well as selenium and beta-carotene. Some antioxidants are vitamins, some are minerals and some are other chemical compounds. They can be human-made or sourced naturally, and they're found in thousands of foods. That damage is called "oxidative stress."Īntioxidants are part of your body's natural defense against oxidative stress. This can cause changes to the structure or function of your cells, which over time can lead to cellular damage.

These harmful molecules come about when atoms in your body lose or gain electrons: Free radicals essentially "steal" electrons from nearby atoms. They do this by fighting off free radicals, unstable molecules that your body generates as byproducts of its daily functions, such as turning food into energy.įree radicals also form in response to environmental stressors on your body, including exposure to sunlight, cigarette smoke and pollutants. Antioxidants are important chemical compounds that may help your body delay or prevent cellular damage.
