What is Exercise and Nutrition Science?

Exercise and nutrition sciences is the scientific study of how lifestyle-related factors like physical activity and nutrition affect the individual as well as the health and function of communities at-large. Our students can develop their skills in a variety of areas from training elite athletes to developing public health policies aimed at nutrition and physical activity to nutrition-related interventions that reduce chronic disease and associated complications from poor diet. We not only train our students in the field of exercise and nutrition sciences, but through our research we develop new projects and programs, and influence public policy to create a lasting change on the health of the world.
