"Let food be thy medicine and medicine be thy food"
How is a Registered Dietitian Nutritionist “RDN” different from a Nutritionist?
The “RDN” credential is a legally protected title that can only be used by practitioners who are authorized by the Commission on Dietetic Registration of the Academy of Nutrition and Dietetics.
Not all nutritionists are registered dietitians, although some Registered Dietitian Nutritionists may call themselves “Nutritionists”. The definition and requirements for the term “Nutritionist” vary. In many states virtually anyone can call him- or herself a “Nutritionist” regardless of education or training.
Individuals with the RD or RDN 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 national registration examination — in addition to maintaining continuing education requirements for re-certification.
