It has been estimated that 35 percents of cancer deaths may be related to dietary factors (Doll and Peto, 1981).The recommendations for dietary change are based on years of scientific research and offer potential for an effective public health approach to cancer prevention.Currently available research shows that diets low in fat and high in fiber, fruits, vegetables, and grain products are associated with reduced risks for many cancers.Vitamin C is an important antioxidant and free radical scavenger in plasma and acts to regenerate active vitamin E in lipid membranes.Vast majority of epidemiologic studies found statistically significant protective effects of vitamin C against cancer.Another area of research is on animal studies which suggested that Selecium decreases the risk of a variety ofturnors, and some epidemiologic studies have shown an inverse relationship between selenium and cancer.
