Dietitians and nutritionists evaluate the health of their clients. Based on their findings, dietitians and nutritionists advise clients on which foods to eat—and those foods to avoid—to improve their health.
Some dietitians and nutritionists provide customized information for specific individuals. For example, a dietitian or nutritionist might teach a client with high blood pressure how to use less salt when preparing meals. Others work with groups of people who have similar needs. For example, a dietitian or nutritionist might plan a diet with limited fat and sugar to help patients lose weight. They may work with other healthcare professionals to coordinate patient care.
