Do free radical
antioxidants hold the key to living longer?
Scientists aren’t
sure, but a new study shows a link may exist. The study,
published in the May 5th issue of Science Express, found that
animals born with the ability to make more of an antioxidant
called catalase lived longer – 18.5% longer than others.
Diseases of aging such as heart disease were slowed down or
lessened in these animals, and antioxidant dietary supplements
may prove to do the same.
Antioxidant
dietary supplements help control damage from molecules
called free radicals.
Free radicals are
unstable molecules lacking an electron – they attack healthy
cells to steal this electron. The resulting damage which kills
cells and harms DNA may be related to aging and diseases,
according to some experts. Free radical antioxidants help
prevent radical damage. |

we eat, breathe and touch causes some type of oxidation or free
radical damage. Particularly abusive is alcohol,
tobacco, prescription drugs, smoked and barbecued food, harmful
chemicals and additives in the foods we eat, sun bathing and
pollutants in the air we breath. They assault your cells, large
enzyme complexes, and DNA. After age 28, the major source of aging
is the production of free radicals. Just the process of aging
increases the amount of free radicals we produce. Scientists have
determined that very large amounts of free radicals accumulated in
your body, may significantly shorten your life span.
"Free
radical" is a term used to describe any molecule that differs
from conventional molecules such that it possesses a free
electron, a property that makes it react with other molecules in
highly volatile and destructive ways.
A free radical is
an unstable molecule that steals an electron from a stable
molecule in order to satisfy its need for repair. When this free
radical destabilizes the stable molecule it creates another free
radical in a vicious chain reaction of cellular destruction. A
single free radical can cause damage to millions of other
molecules in you body, preventing your body from functioning
properly. This molecular destruction is continually
occurring in your body. Free radicals attack us from many
different environmental sources every day.
Some free radicals
arise normally during metabolism. Sometimes the body’s immune
system’s cells purposefully create them to neutralize viruses
and bacteria. However, environmental factors such as pollution,
radiation, cigarette smoke and herbicides can also spawn free
radicals.
This type of free-radical
damage begins at birth and continues until we die. When you
are young the body has extensive repair and replacement mechanisms
that function to keep cells and organs in working order so its
effects are relatively minor. As you get older however, the
accumulated effects of free-radical damage begin to add up.
Free-radical disruption of cell metabolism is part of what ages
our cells. It may also create mutant
cells, leading ultimately to cancer and death.
Free radicals also
attack collagen and elastin, the substances that keep our skin
moist, smooth, flexible, and elastic. These vital tissues become
brittle, fray and break under the assaults of free radicals, a
process particularly noticeable by wrinkles in the face.
Free radical antioxidants play an important role in protecting
your vision. In particular, Vitamins A, E, and C have
been shown to combat age-related macular degeneration (AMD), and
cataracts. Essential fatty acids (EFAs) have also been shown
to support eye health
Free Radicals cause
oxidation in the blood. Once oxidation occurs, disease can result.
Antioxidants keep free radicals from causing oxidation in the
blood, thus neutralizing disease. Also, stress, chemical
pollution, environmental pollution, and the normal aging process
increase the demands put upon the immune system.
Studies over
the last 20 years have shown that free radical fighters found in a
certain group of nutrients, namely antioxidants, can protect
against a great many free radical initiated diseases. Antioxidants
neutralize free radicals and prevent
the harmful effects of oxidation. Studies also indicate
antioxidants do more than protect against free radicals; they also
stimulate the immune system's response to help fight existing
diseases.

1.
A normal atom - such as this oxygen atom - has a
stable number of electrons orbiting its nucleus.
2. Free radicals raid stable atoms of
electrons.
3. Antioxidants replace the lost electrons,
but unlike other types of atoms, do not become charged when
giving up electrons.

Natural
antioxidants include vitamin C, vitamin E, and beta-carotene (the
substance that your body uses to produce vitamin A. Consumption
of antioxidants may help support general health and delay the
signs of aging. The antioxidant properties of vitamins C and
E, are thought to protect the body against the destructive effects
of free radicals. The antioxidant nutrients themselves don’t
become free radicals by donating an electron because they are
stable in either form. They act as scavengers, helping to prevent
cell and tissue damage that could lead to cellular damage and
disease.

not too late to start protecting your cells against the aging
effects of free radical damage. You can look younger and
