Nutrition in the Etiology of Cancer n Epidemiologic research has evaluated the role of diet in the etiology of cancer in different population groups. n Diets contain inhibitors and enhancers of carcinogenesis. n Laboratory studies have served as models to test the effect of food and nutrition on cancer development. n Epidemiologic research has evaluated the role of diet in the etiology of cancer in different population groups. n Diets contain inhibitors and enhancers of carcinogenesis. n Laboratory studies have served as models to test the effect of food and nutrition on cancer development.
