Antioxidants and Healthy Aging
The Free Radical Theory of Aging. The Free Radical theory of
Aging was proposed by Dr D Harman in 1954. It proposed that
the formation of free radicals from chemical reactions in the body
led to the breakdown of cellular health.
Free radicals are unstable molecules that are missing electrons.
These molecules come from our normal metabolism and various
disease states, including high blood cholesterol levels, hypertension
and diabetes, exogenous toxins, cigarette smoking, unhealthy
food choices, pollution, stress and even exercise. They damage
healthy cells by stripping their electrons, making the healthy
cells less able to resist and repair cellular damage.
He amended this theory in 1972 with the
“Mitochondrial Theory of Aging” when he realized that our
mitochondria were producing and being affected by
free radicals and that our mitochondrial health determines our actual life span.
There are numerous degenerative diseases attributed to free radical damage.
Overall, free radicals have been implicated in the development of at
least 60 diseases, including heart disease, cancer, arthritis and
other inflammatory diseases, kidney disease, cataracts,
lung dysfunction, pancreatitis and various skin lesions.
Antioxidants.
Antioxidants are important because they neutralize free radicals
before they can damage our cells. The most important source
of antioxidants is in the food we choose to eat, mostly found in
deeply pigmented fruits and vegetables.
The other source of antioxidants is through supplements like Glutathione.
