Antioxidants are components that neutralize free radicals that play a vital role in cancer, heart disease, and various other diseases. Free radicals tend to be highly reactive chemicals and have the capability to destruct cells. They get formed when a molecule or an atom either loses or gains an electron. Free radicals are generated by the body as a response to radiation or environmental pressures. There are commonly two sources of antioxidants; artificial or natural. Some plant-based foods are commonly believed to be high in antioxidants, and plant-based antioxidants are believed to a type of phytonutrient. The human body, too, produces a few antioxidants, and they are recognized as endogenous antioxidants, whereas antioxidants that come from the outside of the human body are known as exogenous.
Antioxidants, like carotenoids, Vitamin C, and Vitamin E, might help in shielding cells from the damage that free radicals cause, and some other naturally arising antioxidants comprise tannins, flavonoids, lignans, and phenols. Some plant-based foods are acknowledged as the finest sources, and they comprise vegetables, fruits, nuts, whole grains, cocoa, spices, herbs, and seeds.
