Well, that and other foods that are naturally exceptionally high in vitamins, minerals and overall nutritional value.
Antioxidant foods reduce the effects of free radicals - also called oxidative damage/stress, which plays a major role in disease formation. Some of the leading health problems facing us today — including conditions like heart disease, cancer and dementia — have been linked to increased levels of oxidative damage and inflammation. In simplest terms, oxidation is a chemical reaction that can produce free radicals, leading to other chemical chain reactions that damage cells.
