They help prevent and treat illnesses by promoting healthy eating habits. They scientifically evaluate clients' diets and suggest modifications such as less salt for those with high blood pressure or reduced fat and sugar intake for those who are overweight. Dietitians run food service systems for institutions such as hospitals and schools and promote sound eating habits through education and research.
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 programs, and evaluate and report the results. 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 food service department. Community dietitians counsel individuals and groups on nutritional practices designed to prevent disease and to promote good health.
