Antioxidants Article

Here's an article I found on goarticles.com by Mary Porter that I thought would be helpful. It's an article on The Value of Antioxidants. Enjoy...

"How do antioxidants promote better health?

They control the affect of free radical damage. Free radicals are produced in your body as a result of oxidation. Oxidation is a naturally occurring process that takes place when cells use oxygen for fuel.

The byproduct of the burning of oxygen is free radicals. In the oxygen burning process electrons are separated, and some electrons are left isolated. They then begin to fly around looking for another electron to join with. When they find one, they join with it and become stable again. But the electron they joined with may have left another electron behind, isolated and then itself becoming a free radical. It is a chain reaction. They can not be eliminated.

The cells have the ability to control some free radicals within themselves. There are enzymes present in cells that can prevent the free radicals from flying around, and the enzymes can repair the damage that may have been caused. But when there are excessive free radicals, more than the cells can handle, free radicals escape into the body, and continue to fly around, causing more damage.

Free radical damage can influence physical and mental aging. It can be responsible for developing cancer, arthritis, cardiovascular disease, and other degenerative processes.

Some causes of free radical production from our environment today would include air pollution, radiation and X-ray, cigarette smoke, pesticides and other toxic chemicals, emotional stress, and intense exercise.

Cells build their defense against free radicals by combining enzymes with minerals including manganese, zinc, copper and selenium. This combination places itself between the flying electron and its intended target, rendering the flying electron harmless. If the cells don't have enough minerals for enzymes to combine with, they are unable to adequately protect from free radical activity.

Many antioxidants can be accessed through diet. Some sources would be citrus fruits, green vegetables, tomatoes, potatoes, and fortified cereals provide Vitamin C. Green leafy vegetables, whole wheat, oatmeal, soybean oil, corn oil, nuts, and eggs provide Vitamin E. Dark green, yellow, and red vegetables, dairy products and eggs, and yellow fruits provide Beta Carotene. Seafood, liver, cereals and grains provide Selenium. Meat, liver, eggs, seafood, and pumpkin seeds provide Zinc.

All antioxidants don't have the same function. Beta Carotene is good protection from free radicals caused by intense exercise, while Vitamin E and selenium are better equipped to handle those caused by exposure to toxic chemicals. Also, antioxidants protect each other. Beta Carotene protects Vitamin C, which in turn protects Vitamin E. With enough protection, antioxidants are free to travel through the body, guarding against free radical attacks.

Even though antioxidants are available from our diet, we cannot be assured that there are adequate amounts in food today. Between the depleted state of soil used to grow our food, and the processing that are food is subject to, the nutritional value that is left is not enough. Not only is the nutrition available decreased, but the food is also exposed to chemical fertilizers and additives that have the potential to cause even more free radical production.

Some of the benefits as a result of use of antioxidant supplements are increased protection from many forms of cancer, stronger defense against cardiovascular disease, and a more powerful immune system.

I would think, in view of all this, that supplementing with a good, broad spectrum antioxidant would be a healthy choice for anyone."
