Titles of Dietitians and Nutritionists

What’s the difference between Dietitians and nutritionists? While Dietitians and nutritionists both aim to help people improve wellness, there are some important differences between the two titles, and both are often mislabeled.

According to the Academy of Nutrition and Dietetics, the Deunglison Medical Lexicon defines Dietetics as “a branch of medicine comprising the rules to be followed for preventing, relieving, or curing disease by diet.” In the age of rising obesity and all the complications that come with it, more people are seeking assistance for weight loss from these professionals. However, who should one pick to get help from?

A lot of the differences between Dietitians and nutritionists lie with legal restrictions and the necessary qualifications in order to hold the titles. The term “nutritionist” is a looser definition and may refer to anyone who feels they have expertise in the field of nutrition. While there are many degrees and certifications one can get in nutrition education, legally one does not have to have any formal education, training, licensure, or certification in order to call themselves a nutritionist.  The term “dietitian,” often a shortened name for “Registered Dietitian (RD)” or “Registered Dietitian Nutritionist (RDN),” stands for those who meet required education, supervised practice hours, and credentialing standards. This means that while all dietitians are nutritionists, not all nutritionists are dietitians.

Becoming a Nutritionist

Anyone who completes a degree in nutrition can be considered a nutritionist but this can encompass a variety of education levels. Places that you can see nutritionists working include:

  • Hospitals, nursing homes, or long-term care facilities
  • Government positions or local health departments
  • School districts and their food service departments
  • Independent private facilities working with medical professionals
  • Various research settings

Though the title of nutritionist can come from varying sources, various credentials can be gained and so the education and training a nutritionist may pick to undergo may depend on the credentials they desire, or the population and setting with which they would like to work. Popular credentials include becoming a certified nutrition specialist (CNS) or a certified/clinical nutritionist (CN). In order to become a CNS according to the Board of Certification for Nutrition Specialists (BCNS) one should:

  1. Earn a Master of Science or doctoral degree in nutrition or related field.
  2. 35 hours of relevant coursework related to personalized nutrition practices.
  3. 1000 hours of supervised practice.
  4. BCNS personalized nutrition case study reports.

Nutritionists are limited by guidelines set by each state. For example, some states may not allow nutritionists to counsel, diagnose, or treat medical conditions and insurances may hold different standards or reimbursement allowances depending on the credentials held. If you are interested in meeting with a nutritionist, ask about their education and experience to help inform your decision.
