Antioxidants
Ever wondered how you get all those wrinkles? Those annoying crow’s feet at the corners of your eyes?
Alternatively those laugh lines around your mouth. Sure these things are but part of the normal aging process.
However what causes aging anyway? In addition is there any way 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 do not make the distinction between
foreign bodies and healthy cells. In addition 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 do we have 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.
