Did You Know Just That Many Cancers Are Linked To A Vitamin Deficiency?
Antioxidant
Ever
wondered how you get all those wrinkles? Those annoying
crow's feet at the corners of your eyes? Or those laugh
lines around your mouth? Sure, these things are but part
of the normal aging process. But what causes aging anyway?
And is there anyway to retard it?
In
biological systems, the normal processes of oxidation are
what lead to aging. Oxidation causes the production of substances
called free radicals which are highly reactive. These free
radicals can readily react with and damage other molecules.Note
that it says "molecules" so that means free radicals
don't make the distinction between foreign bodies and healthy
cells. And when free radicals start attacking the body's
own cells, you can guess what the results are - Aging.
If only there was a way to get rid of those harmful free
radicals
Well,
have we got good news for you? Free radicals are natural
enemies of antioxidants. The function of antioxidants is
to destroy harmful free radicals, counteracting the damaging
of tissues and in effect, treating aging or causing its
retardation.
Antioxidants
are commonplace in nature. In fact, antioxidants are abundant
in more common vitamins such as retinol or Vitamin A, ascorbic
acid or Vitamin C, tocopherol or Vitamin E, and selenium.
They can be nutrients (vitamins and minerals) as well as
enzymes (proteins in your body that assist in chemical reactions).
Antioxidants are believed to play an important role in preventing
the development of such chronic illnesses as heart disease,
stroke, cancer, Alzheimer's disease, Rheumatoid arthritis,
and cataracts.
Although
antioxidants cannot completely rid our bodies of free radicals,
they can however work to retard or minimize the damage caused.
Antioxidants block the process of oxidation by neutralizing
free radicals. By neutralizing, they themselves become oxidized.
For this reason, our bodies are always in need of a constant
source of antioxidants.
How
antioxidants work is a two-way process. First is the chain-breaking.
This is where the antioxidant comes in to break the chain
reaction of free radicals turning other molecules into free
radicals like them. Chain-breaking is also called Stabilization.
The
other aspect is more on the preventive side. Antioxidant
enzymes like superoxide dismutase, catalase, and glutathione
peroxidase prevent oxidation by reducing the rate of chain
initiation. This time, instead of waiting for the free radicals
to make a long chain of free radicals, antioxidants scavenge
initiating radicals and destroy them before oxidation is
set in motion.
Thus,
aging is delayed and not only that, diseases and other illnesses
caused by harmful free radicals are avoided.

Sure we've all heard about the wonders of antioxidants.
Why, they can practically do anything, except perhaps fix
that jammed doorknob in your closet. Then again, a scientist
might be working on that as well.
