Antioxidants are nutrients that protect our body from oxidative damage caused by things like UV radiation, toxins, and oxygen. Antioxidants can neutralise so-called "free radicals." Free radicals are reactive particles that form in our body as a by-product of our metabolism and fat burning. External factors, such as smoking, environmental pollution, pesticides, and radiation, can increase the production of free radicals. Due to their high reactivity, they can damage cells and tissues. Various types of nutrients can have antioxidant effects. Consider vitamins, minerals, enzymes, and (bio)flavonoids. (Bio)flavonoids are an extensive group of plant substances that contribute significantly to the bright colours of many fruits, vegetables, herbs, and flowers. Well-known antioxidants include vitamin C, vitamin E, zinc, and selenium. Want to know more? Read all about antioxidants here.
