Dietitians and nutritionists are experts in the use of food and nutrition to promote health and manage disease. They advise people on what to eat in order to lead a healthy lifestyle or achieve a specific health-related goal.
Duties
Dietitians and nutritionists typically do the following:
Assess patients' and clients' nutritional and health needs
Counsel patients on nutrition issues and healthy eating habits
Develop meal plans, taking both cost and clients' preferences into account
Evaluate the effects of meal plans and change the plans as needed
Promote better health by speaking to groups about diet, nutrition, and the relationship between good eating habits and preventing or managing specific diseases
Keep up with or contribute to the latest food and nutritional science research
Write reports to document patients' progress
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. They may need to spend time on marketing and other business-related tasks, such as scheduling appointments, keeping records, and preparing educational programs or informational materials for clients.
Although many dietitians and nutritionists do similar tasks, there are several specialties within the occupations. The following are examples of types of dietitians and nutritionists:
Clinical dietitians and clinical nutritionists provide medical nutrition therapy. They work in hospitals, long-term care facilities, clinics, private practice, and other institutions. They create nutritional programs based on the health needs of patients or residents and counsel patients on how to improve their health through nutrition. Clinical dietitians and clinical nutritionists may further specialize, such as by working only with patients with kidney diseases or those with diabetes.
Community dietitians and community nutritionists develop programs and counsel the public on topics related to food, health, and nutrition. They often work with specific groups of people, such as adolescents or the elderly. They work in public health clinics, government and nonprofit agencies, health maintenance organizations (HMOs), and other settings.
Management dietitians plan food programs. They work in food service settings such as cafeterias, hospitals, prisons, and schools. They may be responsible for buying food and for carrying out other business-related tasks, such as budgeting. Management dietitians may oversee kitchen staff or other dietitians.
