Registered dietitian nutritionists, or RDNs, are the food and nutrition experts, translating the science of nutrition into practical solutions for healthy living. The expertise, training and credentials that back a registered dietitian nutritionist are vital for promoting positive lifestyle choices.
A registered dietitian nutritionist has met academic and professional requirements including:
- Earned a bachelor’s degree with course work approved by the Academy of Nutrition and Dietetics’ Accreditation Council for Education in Nutrition and Dietetics (ACEND). Coursework typically includes food and nutrition sciences, foodservice systems management, business, economics, computer science, sociology, biochemistry, physiology, microbiology and chemistry.
- Completed an accredited, supervised practice program at a health care facility, community agency or foodservice corporation.
- Passed a national examination administered by the Commission on Dietetic Registration.
- Completes continuing professional educational requirements to maintain registration.
Approximately 50 percent of RDNs hold advanced degrees. Some RDNs also hold additional certifications in specialized areas of practice, such as pediatric or renal nutrition, nutrition support and diabetes education.
