Traditionally, dietitians and nutritionists plan nutrition programs and supervise the selection, preparation and serving of food. They evaluate clients' diets and nutritional status, suggest modifications, and promote healthy eating habits.
Dietitians also work as educators and researchers.
Clinical dietitians provide nutritional services for patients in institutions such as hospitals and nursing homes. They assess patients' nutritional needs, develop and implement nutrition intervention, and evaluate and report outcomes. They also confer with doctors and other health care professionals in order to coordinate medical and nutritional needs. In addition, clinical dietitians in nursing homes or small hospitals may also manage the foodservice department. Community dietitians counsel individuals and groups on nutritional practices designed to prevent disease and to promote good health.
