Antioxidants
As their name suggests, antioxidants combat the oxidation – the rust, if you will – of our cells. Fruit and vegetables are some of the best sources of antioxidant vitamins A, C & E, which can help repair, prevent or limit oxidative damage to our cells caused by free radicals. In addition to dietary antioxidant vitamins, our bodies make others, including glutathione, lipoic acid and melatonin.
Antioxidants take a nosedive after overindulgent meals, but fruit for dessert helps to undo the damage. In contrast, an American Heart Association review of studies on antioxidant supplements found that they are largely ineffective in preventing heart disease.
