antioxidants and what do they do?
In the life
cycle of normal tissue cells, oxygen molecules are present and usefull.
These oxygen molecules travel in pairs. Sometimes one of the pair will
be used and the other remains left. That lone oxygen molecule is called
a "free radical". Free radicals easily attach onto cells causing an
effect, much like that of rust, called oxidative damage, which can bring
about intense cell damage and interferes with the cell’s ability to
function properly. Over time this may lead to cancer or cardiovascular
disease, arthritis, Alzheimer’s Disease and other health problems that
is linked to aging.
Antioxidants are compounds that neutralize
free radicals because they supply a positive charge to the unpaired
oxygen so it cannot damage cells. This renders the free radical useless
and the threat is gone. Antioxidants can also prevent oxidation by
"guarding" or creating barriers around cell tissue and bonding with free
radicals as they attack.
