What is the difference between a nutritionist and a dietitian?

From the Guidelines

A dietitian is a healthcare professional with specialized training in nutrition, whereas a nutritionist may not have the same level of education or credentials.

Key Differences

• A dietitian, also known as a registered dietitian (RD) or registered dietitian nutritionist (RDN), has completed a bachelor's degree in nutrition or a related field, completed an internship, and passed a national exam to become certified 1.
• In contrast, the term "nutritionist" is not always regulated, and individuals with varying levels of education and training may use this title.

Role of a Dietitian

• A dietitian plays a crucial role in the management of diabetes, as they provide individualized medical nutrition therapy to help patients achieve their treatment goals 1.
• Dietitians work with patients to develop personalized eating plans, taking into account their nutritional needs, lifestyle, and health goals 1.

Importance of Credentials

• The American Diabetes Association recommends that individuals with diabetes work with a registered dietitian or a similarly credentialed nutrition professional for nutrition therapy 1.
• Having a registered dietitian as part of the healthcare team can help ensure that patients receive evidence-based nutrition recommendations and individualized care 1.
