Antioxidants in Green Tea Increase Life Expectancy!
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.
The building block nutrients of antioxidant enzymes include the minerals manganese, zinc, and copper for SOD and selenium for glutathione peroxidase. In addition to antioxidant enzymes, many vitamins and minerals may also have antioxidant properties. These include vitamins C, E, A (beta-carotene) and nutrients such as lutein, lycopene, vitamin B2, coenzyme Q10, and cysteine (an amino acid).
The human body is incapable of producing its own concentration of antioxidants. For this reason, we depend solely on our diet in order to get the store of antioxidants we need to combat diseases. Antioxidants protect the body from harmful, excess free radicals, sweeping them up before they can cause damage.
During oxidation, certain chemical substances are produced and among them are those that are highly reactive and chemically unstable. These substances are called free radicals. Free radicals can be harmful to the body, especially if there is an excess of them. They may cause damage to the cell membranes, causing them to weaken.
A Little Background on Chemical Bonding When talking about antioxidant and free radicals, we can't help but touch a little on biochemistry. You probably remember from your old high school days that the human body is composed of many different cells and each cell is composed of many different molecules.
Multiple antioxidants tend to work synergistically and far more effectively when they are taken together than when they are taken as a single antioxidant. Most antioxidant supplements you find in health stores today contain a standard ingredient base. Antioxidant supplements generally contain vitamin C, vitamin E, beta-carotene, and the mineral selenium.
