I have read that antioxidants help in the prevention of infections and are necessary for a healthy life. But can diabetics include antioxidants in their diet? If yes what are the benefits? What are the food sources of antioxidants and how to include them in the diet? Free radicals are molecules produced during metabolic process that damage healthy cells and increase your risk of inflammation and infections. Whereas antioxidants are compounds that neutralise these harmful oxygen species in the body and in turn prevent you from cancer heart diseases and problems with the normal functioning of brain and immune system.
