Welcome to Nutrition Education for Cancer Prevention. The materials provided on this site are freely accessible for educational purposes. The content of the site is provided by students enrolled at Iowa State University under the supervision of Dr. Ruth MacDonald, Professor and Chair of Food Science and Human Nutrition. The goal of our work is to provide up to date information about nutrition topics, including the role of dietary factors in cancer, to the public. For each topic, you will find a slide presentation with oral explanation and a knowledge builder. New topics are added each fall and spring semester.
