Free radical theory of ageing

Free radicals are unstable molecules with an extra electron that go around stealing electrons from wherever they can, causing oxidative damage to cell membranes, DNA (deoxyribonucliec acid) and other proteins. Our body's metabolic processes, tobacco smoke, pollution and ultraviolet light generates free radicals. When cells lose electrons, they become oxidized; this is termed oxidative damage. The term, oxidative stress refers to an imbalance between the production of free radicals and the respective anti-oxidant defences of the body.

Some of the diseases that might be caused by free radicals include:

  • Alzheimer's disease
  • CancerHeart disease
  • Rheumatoid arthritis
  • Diabetes
  • Macular degeneration of the retina and cataracts
  • Skin ageing and wrinkling
