The prefix "anti" means against, in opposition to, or corrective in
nature. In order to understand antioxidants, it helps to learn what
exactly these agents oppose and correct.

Within the human body, millions of processes are occurring at all
times. These processes require oxygen. Unfortunately, that same life
giving oxygen can create harmful side effects, or oxidant substances,
which cause cell damage and lead to chronic disease.

Oxidants, commonly known as "free radicals," are also introduced
through external sources such as exposure to the sun or pollution.
Other mediums include stress, as well as things that people put into
their bodies, such as alcoholic beverages, unhealthy foods, and
cigarette smoke.

In much the same way as oxidation creates rust, causing a breakdown on
the surface of inanimate objects, oxidation inside the body causes a
breakdown of cells. Free radicals produced by this breakdown attack
healthy cells, usually DNA as well as proteins and fats. This chain of
events weakens immunological functions as well as speeding up the
aging process, and is also linked to several diseases such as
cataracts, various forms of cancer, and heart disease. Some studies
indicate possible links to arthritis and several other chronic
conditions.

Antioxidants, or anti-oxidation agents, reduce the effect of dangerous
oxidants by binding together with these harmful molecules, decreasing
their destructive power. Antioxidants can also help repair damage
already sustained by cells.

Certain antioxidant enzymes are produced within the body. The most
commonly recognized of these naturally occurring antioxidants are
Superoxide Dismutase, Catalase, and Glutathione. Superoxide Dismutase
changes the structure of oxidants and breaks them down into hydrogen
peroxide. Catalase in turn, breaks down hydrogen peroxide into water
and tiny oxygen particles or gases. Glutathione is a detoxifying
agent, which binds with different toxins to change their form so that
they are able to leave the body as waste.

Other antioxidant agents are found in foods, such as dark green leafy
vegetables. Items high in vitamin A, vitamin C, vitamin E, and beta-
carotene are believed to be the most beneficial. These nutrients are
commonly found in fruits and vegetables, those with the strongest
colors being healthiest. Orange and red peppers, tomatoes, spinach,
and carrots are examples.

Choosing raw fruits and vegetables rather than cooked, provides the
highest concentration and best absorption of antioxidants. Dietary
supplements are also available for those that do not consume enough
antioxidant-producing foods.

There are a lot of different supplements that you can take and can be
purchased in many different stores in your area, for a quick look at
those choices you can search the internet, or go to some well known
stores that offer not only a great selection but also very good prices
and service, some of my favorites are: http://www.thecatalog.com &
