They have also been implicated in certain cell signaling processes. The two most important oxygen-centered free radicals are superoxide and hydroxyl radical. They are derived from molecular oxygen under reducing conditions, such as when a person breathes. However, because of their high reactivity, free radicals often participate in unwanted side reactions resulting in cell damage. For the past decade, countless studies have been devoted to the beneficial effects of antioxidant enzymes. It has been found that a substantial link exists between free radicals and more than sixty different health conditions, including the aging process, cancer, and atherosclerosis. 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 group of researchers who conducted the study say that a compound extracted from the seeds of red grapes called Activin (tm) is that substance with powerful antioxidant red grapes properties. Because of its apparent powerful benefits, Activin was dubbed as the "super" antioxidant red grapes. Antioxidants, it seems, have created quite a huge wave in the scientific community that is devoting countless journals and magazine articles about their many benefits. Antioxidants are substances that work on free radicals, or more particularly work to counteract the damaging effects of these harmful oxygen byproducts. The function of antioxidant foods is to hunt down free radicals and destroy them. What are Free Radicals? Free radicals are highly reactive chemical substances that are produced when the body undergoes the process of oxidation. The reason that free radicals are highly reactive is that they lack electrons, which cause them to be highly unstable. In January, Engeseth and Jason McKibben, a researcher with Anheuser Busch in Santa Monica, CA, reported in the same journal that the dietary antioxidants in honey were more effective compared to traditional preservatives, such as butylated hydroxytoluene and tocopherol in slowing oxidation in cooked, refrigerated ground turkey.
