Science helps make people's lives better in a myriad of ways — from improving their daily diets to achieving medical breakthroughs that help cure life-threatening diseases. All majors in the Department of Nutrition Science have a strong science component including organic chemistry, biochemistry, and human physiology and teach skills for helping make people's lives better.
