This actually sets off a chain reaction that can damage the body's proteins and cell membranes, weaken the cell's natural defenses, and disrupt the cell's DNA. Such damage, when accumulated, could lead to degenerative conditions. Fortunately, nature has provided us with a system to help control free radicals. 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. Certainly, it can't be completely dispelled. It can however be controlled. Now, by "control", we don't mean controlling the process of oxidation itself, but controlling the outcome of it. The oxidation process is what makes a cut apple turn brown and causes the surface of butter to turn dark yellow. The disease claims the lives of over 100,000 annually. Perhaps due to this alarming number, much of scientific researches conducted in the US today have recently been focused on how antioxidant vitamins may reduce the risk of cardiovascular disease. Previous studies have shown that antioxidant vitamins, such as vitamin E, vitamin C, and beta carotene (a from of vitamin A), have potential health-promoting properties. Because atoms seek to reach a state of maximum stability, an atom will try to fill its shell with electrons by: Gaining or losing electrons to either fill or empty its outer shell Sharing its electrons by bonding together with other atoms in order to complete its outer shell Free Radicals: The Formation The free radicals are formed when weak bonds between atoms are split. These are substances that defend our body against the ravages brought on by free radicals. The first ever antioxidants to catch the attention of scientists and the vitamin supplement industry is beta-carotene or more commonly known as Vitamin A. Now, you can find antioxidant supplements in the form of Vitamin A capsules in almost any pharmacy or health food store.
