Antioxidants
facts - What is it?
What exactly is an antioxidant? By definition, it is a chemical
substances, found in nature or made in the laboratory, that can
protect
against oxidation damage caused by free radicals
which harms or kills cells.
Where
do free
radicals come from?
Free
radicals are left-over stuff (byproducts) of metabolism that
uses oxygen in
the process. And pretty much every cell in your body uses oxygen for
metabolism. They are everywhere since all earthly life uses oxygen
for metabolism.
What
do
these free-radicals do to our body and cells?
Free-radicals are highly reactive. When they come in contact
with cell membranes or other cellular structures, they chemically react
with them and cause a certain amount of damage.
The
free-radicals made during metabolism, if not removed, are strongly
suspected to
cause many diseases
such as heart disease,
premature aging, Alzheimer's disease, cancer, diabetes, Parkinson's
disease and cataracts.
