What is a Registered Dietitian?

Many people mistakenly use the terms “dietitian” and “nutritionist” interchangeably.  Although these two professions are related, they do have distinctive categories. The biggest difference between dietitians and nutritionists lies in the legal restrictions that each title carries. In order to be considered a registered dietitian (RD) or registered dietitian nutritionist (RDN), he or she must complete specific education and training established by the Accreditation Council for Education in Nutrition and Dietetics (ACEND).  A career as a dietitian typically involves dealing with individual clients on a case-by-case basis. Daily responsibilities for an RD will vary depending on where he or she works, but typical duties include:

  • Assessing client health
  • Formulating realistic and worthwhile goals for clients
  • Creating a holistic health plan including diet and exercise plans for individual clients
  • Supporting and motivating clients with regular meetings
  • Keeping track of client progress through anthropometric data
  • Using evidence-based science to inform decisions for the wellbeing of their clients

It’s important to remember that there are many different types of clients for dietitians. They can work with a wide range of individuals including those who suffer from diabetes, high blood pressure or eating disorders, or patients simply pursuing a healthier lifestyle. No matter who they work with, a dietitian is key pillar of support and motivation.

What is required to be a Dietitian?

According to the Academy of Nutrition and Dietetics, registered dietitians are required to complete a formal education program that results in at least a baccalaureate degree.  Many dietitians will also hold advanced degrees, such as Master’s Degrees in related fields completed during or after their internship.  In addition, the program must provide coursework that covers subjects in: food and nutrition sciences, computer science, chemistry, business, foodservice systems management, microbiology, sociology, biochemistry, physiology, anatomy, and economics

Under the Academy of Nutrition and Dietetics (AND) rules, all Dietetic Internships must be at least 1200 hours in length. Each internship lasts from eight to 24 months and they must be an ACEND-accredited program.  After completion degree in a nutrition-related field with required coursework and 1200 hours of qualified internship time, an individual must successfully pass the CDR registration examination to obtain their registered dietitian (RD) or registered dietitian nutritionist (RDN) credential. After filing for, and obtaining, state licensure, a RDN must complete continuing professional education credits each year needed to maintain registration.
