In the realm of nutrition and wellness, Registered Dietitians (RDs) play a vital role in helping individuals achieve their health goals through evidence-based guidance and support. In this blog, we'll delve into what it means to be a Registered Dietitian, differentiate between RDs and nutritionists, explore various specializations within the field, and highlight the valuable assistance RDs can provide.

What is a Registered Dietitian?

Registered Dietitians (RDs) are highly trained healthcare professionals who specialize in translating scientific research into practical dietary advice. To become an RD, individuals must complete a rigorous educational and experiential pathway, including:

  • Obtaining a bachelor's degree in dietetics or a related field
  • Completing a supervised internship program accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND)
  • Passing a national examination administered by the Commission on Dietetic Registration (CDR)
  • Maintaining ongoing continuing education to stay abreast of the latest developments in nutrition science and practice

The Difference Between Registered Dietitians and Nutritionists

While the terms "Registered Dietitian" and "nutritionist" are often used interchangeably, there are important distinctions between the two. In the United States, the title "Registered Dietitian" is a legally protected term, indicating that an individual has met specific educational and professional requirements, including licensure or certification. On the other hand, the title "nutritionist" is not regulated in the same way and may be used by individuals with varying levels of education and expertise in nutrition.
