“What is the difference between a “Registered Dietitian Nutritionist” and a “Nutritionist”?

A Registered Dietitian Nutritionist is an expert in food and nutrition. Many people out there call themselves “Nutritionists” when all they have completed is a few courses in nutrition or lead healthy lifestyle themselves. They can be great role models; however they do not have the proper training or education to be considered an expert in nutrition. Registered Dietitian Nutritionists have certain qualifications and need continuing education to keep their credentials:

  • Earn 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.
  • Complete an accredited, supervised practice program at a health-care facility, community agency, and foodservice corporation.
  • Pass a national examination administered by the Commission on Dietetic Registration.
  • Complete continuing professional educational requirements to maintain registration.

*If you are paying for advice and counseling, you want someone who is the best at what they do. Registered Dietitian Nutritionists have the most training and valuable knowledge when it comes to food and nutrition. If you want the best, seek a Registered Dietitian Nutritionist.
