Oxidation is nothing but the chemical reaction or metabolism occurring in our bodies necessary for growth and maintenance.But oxidation also causes the production of 'free radicals'.'Free radicals' are highly corrosive and damage the cell by reacting with it.
To create energy,our body cells which are in billions in number need oxygen.In this normal metabolic process some oxygen molecules lose an electron thereby losing their stability.These unstable oxygen molecules which are called free radicals try to stabilize themselves by snatching electrons from nearby molecules resulting in more free radicals that damage healthy tissues.
Free radicals damage healthy tissues.They attack cells to damage the cell DNA that might result in mutation of cell leading to cancer.Free radicals cause aging.They attack and chip away the surface of artery walls resulting in pock marks enabling the LDL cholesterol fat to stick to the walls that may affect or block blood flow.
To counteract this ill effect of the oxidation process, our body produces it's own antioxidant enzymes that are programmed to give up their electrons to the free radicals there by minimizing the damage to the cells.But this not enough so it is advisable to take food supplements rich in antioxidants.
Antioxidants are necessary to neutralize ill effects of oxidation occurring due to our metabolism.Antioxidants can be described as molecules having the property to slow down the oxidation process and thereby limiting the production of 'free radicals'.
The free radicals produced during oxidation, react with the biological structure of cells by damaging it.The damage accumulates over a period of time,resulting in aging.To control the process of aging, antioxidants are used as reducing agents.It was found that the process of aging slows down considerably if antioxidants supplements such as vitamin A,vitamin B,vitamin C,vitamin E,and minerals such as magnesium,zinc,selenium are used.These antioxidants are found to be more effective if they work together and so it is advisable to consume as many antioxidants as possible from the variety of sources.
It is quite possible in future to reduce the rate of aging when breakthrough advances in genetics are made to reduce the rate of aging by molecular repair and rejuvenation of deteriorated cells.It has long been the dream of researchers to slow down or preferably to halt the process of aging so that people can enjoy a long life with vigor and energy and lead happy lives irrespective of age.
Now it is possible to fight the process of aging with the help of new and effective antioxidants.New developments in advanced research on anti aging medicine and nutrition has caused rise in production of antioxidant supplements such as vitamin C,E and others to slow down the process of aging.
Antioxidants are also used in many industries, such as preservatives in food and cosmetics industries by preventing the degradation of rubber and gasoline.Thus supplements antioxidants are found to be beneficial against age related ailments and aging.Antioxidants are largely used as in dietary supplements industry in the hope of maintaining health and preventing diseases such as cancer and coronary heart disease.
