The Varying Shades of "Nutritionist"

Inspired by the ChicagoTribune and my own confusion when I started at the ITPCU, I thought a post on definitions for nutrition counselling was appropriate.  Personally, I field questions on the difference between an M.D. and a D.O. all the time, and I think that Certified Nutrition Specialists and Registered Dieticians can cause similar confusion.

Certified Nutrition Specialist  (CNS):  These practitioners have an advanced degree (Master’s or higher) in nutrition or a related field from an accredited university.  They take certification exams (the Certification Board for Nutrition Specialists, or CBNS) to qualify them to practice as a CNS. Post-graduate study includes many hours of supervised experience in nutrition.  A CNS aims to improve health through science-based nutrition therapy and evidence-based practice.  CNS may work in hospitals, outpatient medicine, or in private practice.

Registered Dietician (RD):  These practitioners have an undergraduate degree or more in nutrition, dietetics, food sciences, or food service management from an accredited college or university.  The Commission on Dietetic Registration of the American Dietetic Association (ADA) registers RDs, requires them to pass a exam by the Commission of Dietetic Registration, and necessitates continuing education requirements in order to upkeep certification.  RDs much also complete a practical internship and have many hours of supervised experience.  RDs are more likely to work in private practice and some go on to get advanced degrees such as a CNS.  RDs also often work in school or hospital cafeterias, nursing homes, or as community educators. 

Note:  Since there are no national guidelines for nutritionists, people can be called a “nutritionist” with varying levels of education and training.  Check for up-to-date certification in any CNS, RD, or anyone else you see for nutrition counseling!  Other nutrition degrees may include Licensed Dietitian/Nutritionist, Registered Dietetic Technician, Certified Clinical Nutritionist, and Certified Nutrition Consultant.
