A registered dietitian (RD) or registered dietitian nutritionist (RDN), is a dietitian who meets all of a set of special academic and professional requirements, including:
- the completion of a bachelor’s degree with an accredited nutrition curriculum
- satisfactory performance on the registration exam
- an internship at an approved health-care facility, foodservice organization, or community agency
Most RDs work in the treatment and prevention of disease (administering medical nutrition therapy, as part of medical teams), often in hospitals, health-maintenance organizations, private practices, or other health-care facilities. In addition, a large number of registered dietitians work in community and public-health settings, and/or in academia and research. A growing number of dietitians work in the food industry, journalism, sports nutrition, corporate wellness programs, and other non-traditional dietetics settings.
