Dietitians and nutritionists evaluate the health of their clients. Based on their findings, dietitians and nutritionists advise clients on which foods to eat—and which to avoid—to improve their health.
Many dietitians and nutritionists provide customized information for specific individuals. For example, a dietitian or nutritionist might teach a client with diabetes how to plan meals to balance the client's blood sugar. Others work with groups of people who have similar needs. For example, a dietitian or nutritionist might plan a diet with healthy fat and limited sugar to help clients who are at risk for heart disease. They may work with other healthcare professionals to coordinate patient care.
Dietitians and nutritionists who are self-employed may meet with patients, or they may work as consultants for a variety of organizations.
