The prefix ‘anti’ means against, in opposition to, or corrective in nature. In this case, the ‘anti’ in antioxidant describes the effect these chemicals have against oxidants.
Oxidants, usually referred to as ‘free radicals’ are produced as a natural by-product of the millions of biochemical processes undertaken by the body every minute. The same life-giving oxygen that supports all the functions of the body creates these harmful by-products which cause cell damage, usually to DNA, fats and proteins.
Free radicals also enter the body through external influences such as exposure to the sun, pesticides and other kinds of environmental pollution. In addition, their levels are increased by mental and physical stress, the consumption of alcoholic beverages, unhealthy foods, and cigarette smoke.
In much the same way as oxidation causes rust on cars, oxidation inside the body causes a breakdown of cells. If the amount of free radical oxidation in the body is allowed to rise to an unhealthy level, it can result in extensive damage to cellular components and can accelerate the ageing process.
