Dietetics

Common questions I hear are “What is a dietitian?” and “What do dietitians do?”  These questions are best answered by the American Dietetics Association:

“A registered dietitian is a food and nutrition expert who has met academic and professional requirements including:

  • Earned a bachelor’s degree with course work approved by ADA’s Commission on Accreditation for Dietetics Education. 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 RDs hold advanced degrees. Some RDs also hold additional certifications in specialized areas of practice, such as pediatric or renal nutrition, nutrition support and diabetes education.”

What services do RDs provide?

“The majority of registered dietitians work in the treatment and prevention of disease (administering medical nutrition therapy, as part of medical teams), often in hospitals, HMOs, private practice or other health care facilities. In addition, a large number of registered dietitians work in community and public health settings, academia and research. A growing number of registered dietitians work with food and nutrition in industry and business, journalism, sports nutrition, corporate wellness programs and other non-traditional work settings.”

How is an RD different than a nutritionist?

“The ‘RD’ credential is a legally protected title that can only be used by practitioners who are authorized by the Commission on Dietetic Registration of the American Dietetic Association.

“Some RDs may call themselves “nutritionists,” but not all nutritionists are registered dietitians. The definition and requirements for the term “nutritionist” vary. Some states have licensure laws that define the range of practice for someone using the designation “nutritionist,” but in other states, virtually anyone can call him- or herself a “nutritionist” regardless of education or training.

“Individuals with the RD credential have fulfilled specific requirements, including having earned at least a bachelor’s degree (about half of RDs hold advanced degrees), completed a supervised practice program and passed a registration examination — in addition to maintaining continuing education requirements for recertification.”
