By reducing exposure to free radicals and increasing the intake of antioxidant enzyme rich foods or antioxidant enzyme supplements, your body's potential to reducing the risk of free radical-related health problems is made more palpable. The human body produces several types of antioxidant enzymes. The antioxidant enzymes include superoxide dismutase (SOD), catalase, and glutathione peroxidase. Because it is the nature of free radicals, which is basically an atom with an unpaired electron, to achieve stability, they will try to do so by capturing the needed electron from other molecules. When the free radicals steel electrons from a stable molecule, that molecule will become a free radical itself, beginning a chain reaction. The most common antioxidant supports are in the form of vitamins, specifically vitamin A, vitamin C, and vitamin E. In addition, there is good evidence that bilirubin and uric acid can act as antioxidant support to help neutralize certain free radicals. Antioxidant support can be found in almost everything that we eat. Prior, a USDA nutritionist and research chemist based in Little Rock, Ark explains that berry antioxidants were ranked according to their total antioxidant capacity. However, they were surprised to find that besides berry fruits, antioxidants may also come from the most unexpected foods as well. Prior and his colleagues used the most advanced technologies available to tabulate antioxidant levels in more than 100 different types of berry fruits, vegetables, nuts, and spices. Flax oil is the richest source of lignans. Diets high in lignans can lead to a lower chance of getting colon, prostate, and breast cancer. As an antioxidant, the flax oil's lignans can help boost the body's immune system, keeping harmful, disease-causing germs from damaging the cells. These plant hormones are also believed to block the formation of hormone-based tumors. We've been eating them for centuries and it's only now that scientists are beginning to discover exactly what makes them healthy for the body. Antioxidants. What exactly are they? The term is familiar to us. We hear them mentioned all the time whenever there's a new scientific study being released in the American Health Journal or some such explaining how antioxidant juice from berries can aid in liver function or how antioxidant juice from red wine is the scientific reason behind the French paradox.
