Every time we breathe in, 2% of the oxygen that enters our bodies turns into bad oxygen (free radicals) that oxidizes us. This bad oxygen can be converted into good oxygen if we give it an antioxidant electric charge. If it does not get this charge from antioxidants, it robs our cells, making them sick or killing them, a process known as oxidation. An industrialized lifestyle tends to raise oxidation levels due to poor diet, pollution, stress, etc. As we get older we also need more antioxidants, because our bodies generate fewer antioxidant enzymes.
