The field of nutrition and dietetics has a strong emphasis on public health and a commitment to educating all individuals about the importance of making proper dietary choices. Dietitian nutritionists use nutrition and food science to help people improve their health. Nutrition and dietetic technicians work with dietitian nutritionists to provide care and consultation to patients. Both dietitian nutritionists and nutrition and dietetic technicians may also provide general nutrition education. Both are nationally credentialed and are an integral part of health care and foodservice management teams.
