Free Radicals
As the name implies, free radicals are "revolutionaries"
that seek to turn over the body's normal processes by running renegade at the cellular level.
No friend to maintaining good health, free radicals are involved in
the progression of almost every disease - including heart disease, cancer, arthritis, Alzheimer's disease, Parkinson's disease - as well as common wrinkles and the process of
aging.
So where do these cells that reek so much havoc actually come from?
Reigning in free radicals
To understand the process, it should first be noted that oxygen molecules
have two electrons. When one is missing an electron, it becomes unstable and goes in search of another electron from the next
molecule it encounters. As a result, the next molecule becomes a free radical because it is missing an electron. Ultimately,
a single free radical may start a chain reaction of new free radicals causing damage to your cells.
Most alarmingly, free radicals can go on to attack DNA, the genetic material
of cells and cause them to mutate, the first step on the path to cancer.
Protecting against free radicals gone wild
This process of "oxygen molecules gone wild" is commonly known
as oxidation. But there are ways to protect yourself against the worst influences and even repair the damage they may have
already caused by supplying your body with plenty of antioxidants
found in fresh fruits, legumes, and vegetables and in vitamin
supplements such as Vitamin C and Vitamin E.

In addition to proper nutrition, other rules to limit the formation of
free radicals include:
Exercise - keeping your body strong and fit through regular exercise usually results in the formation of fewer free radicals.
Eliminate toxins from the environment - cigarette smoke, chlorine
in water, pesticides in foods, smog.
Protein - made up of amino acids from which the body makes protective
antioxidants. Get proper sleep - one of the most powerful scavengers of free radicals is melatonin, a hormone released when you sleep. Stress management is also very important to reducing free radical formation, as persistent emotional stress very often translates into physical ailments and, at worst, serious disease.
