Antioxidant Vitamins and genus pubic louse Cancer is peerless of the worlds number one killers nearly 75% of every(prenominal) Ameri back ends be affected by this disease. Thus, much time and research has been regularize into finding a preventative means of slowing the deaths attributed to this disease.

These radicals immediately attach themselves to separate cells in order to balance out the number of electrons and become stable. erst formed, these free radicals can have a very destructive concern on a cell. Those radicals which do not cause death to the cell can stimulate the growth of cancer when they interact with and cause damage to the desoxyribonucleic acid within the cell. Scientific evidence suggests that these oxygen free radicals sour strategic roles in the expansion of tumors and the acquisition of malignant properties. (Role of Oxygen poverty-stricken Radicals European Journal of Cancer. 32A(1)30-8, 1996 Jan.) To prevent this free radical damage, the body utilizes a defence force system made up of antioxidants. The antioxidant molecules interact with t he oxygen free radicals and game the spread of cancer causing cells with damaged DNA in front opposite vital molecules are damaged. The main micronutrient antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, a puff coat known as selenium is required for the proper cognitive operation of one of the bodys antioxidant enzyme systems. Since the body cannot produce these micronutrients itself, they must be ingested through the diet.

This site is simply a summary a beginners guide to an ever-changing world of antioxidant research. Antioxidants and the role of oxygen free radicals Antioxidants work in protecting your body from cancer by reducing the effects that oxygen free radicals have on cell damage. This oxidative stress has both internal (digestion of certain nutrients, fighting off bacteria, etc.) and external or environmental causes. The oxygen free radicals are atoms or groups of atoms with unpaired electrons formed between the interaction of oxygen and certain molecules. These radicals immediately attach themselves to other cells in order to balance out the number of electrons and become stable. Once formed, these free radicals can have a very destructive impact on a cell. Those radicals which do not cause death to the cell can stimulate the growth of cancer when they interact with and cause damage to the DNA within the cell. Scientific evidence suggests that these oxygen free radicals play important roles in the expansion of tumors and the acquisition of malignant properties. (Role of Oxygen Free Radicals European Journal of Cancer. 32A(1)30-8, 1996 Jan.) To prevent this free radical damage, the body utilizes a defense system made up of antioxidants. The antioxidant molecules interact with the oxygen free radicals and halt the spread of cancer causing cells with damaged DNA before other vital molecules are damaged. The main micronutrient antioxidants are vitamin E, beta-carotene, and vitamin C. Additionally, a trace metal known as selenium is required for the proper functioning of one of the bodys antioxidant enzyme systems. Since the body cannot produce these micronutrients itself, they must be ingested through the diet.

It is a fat soluble vitamin found in nuts, seeds, vegetable and fish oils, whole grains, fortified cereals, and apricots.
