NUTRIENTS - Assignment fountm other bio-molecules present in the cellular structures like the cell membrane and DNA, leading to their demolition through oxidative damage (Knight, 1998).The authoritative antioxidant vitamins are vitamin A, beta carotene, vitamin C and vitamin E while the important antioxidant minerals are Selenium, Zinc, Manganese and Copper. These vitamins and minerals are an integral part of the abandon radicals scavenging enzyme system. The four signifi tooshiet antioxidant enzymes that neutralize the vacate radicals are superoxide dismutase, catalase, methionine reductase and glutathione peroxidase.Most minerals and vitamins might not be effective alone in scavenging fire radicals, but can act as effective antioxidants in a synchronized manner. Major sources of antioxidant vitamins and minerals are fish oils, avocados, pomegranate, banana, raspberries, mango, spirulina and pumpkin. Most nuts and seeds also serve as a major source of antioxidant minerals (Ben zie, 2003).The group O free radicals are neutralized by vitamins and minerals in a concerted way. Free radicals are form due to many reasons either by cleaving water molecules into the hydroxyl free radical superoxide radicals and lipid peroxides by the action of ionizing radiations, and toxic pollutants. The fat molecules are broken down to liberate the reactive sebaceous acid peroxy radical. The free radicals have one unpaired electron in outermost valence shell, so in order to become stabilized it can accept protons from other bio-molecules present in the cellular structures like the cell membrane and DNA, leading to their destruction through oxidative damage (Knight, 1998).Free radicals can also be liberated from the diet we consume. A fat rich diet can annex free radical activity because fatty acids are readily oxidized to fatty acid free radicals. Cooking fats at high temperatures, mainly frying foods in oil, may produce large exit of free radicals. Hence if the diet does not contain enough antioxidant vitamins and
