As the body’s cells use oxygen to produce energy, some
highly unstable molecules known as free radicals are produced.
These are molecules or atoms with missing electrons. These
molecules rush around grabbing electrons from other molecules to stabilize
themselves, in the process creating new free radicals. An electron-grabbing
chain reaction starts that damages tissues and contributes to ageing and
degenerative disease.
The good guys who put a stop to this are the antioxidants,
among which are vitamins E, C and beta carotene. They seek out the free
radicals and inactive them - becoming inactive themselves in the process. This
is why a regular supply of antioxidants is needed, and the best way of ensuring
this to eat a natural unrefined plant food diet.
