The terms “dietitian” and “nutritionist” are often used interchangeably, sometimes leading to confusion about the qualifications and roles of these professionals. While both types of professionals guide people on healthy eating habits, significant distinctions exist, particularly concerning credentials, legal recognition and scope of practice.
Understanding these differences is important for those considering a career in nutrition and for those seeking nutrition advice. A registered dietitian (RD) or registered dietitian nutritionist (RDN) must complete specific educational and professional requirements. Lamar University’s online M.S. in Nutrition with a Specialization in Applied Nutrition is a great option for people hoping to pursue either of those roles. Requirements for either include:
- A bachelor’s degree from an accredited program
- Completion of an ACEND-accredited supervised practice program
- Passing the Commission on Dietetic Registration (CDR) national exam
- Maintaining continuing education requirements
- As of 2024, a graduate degree is required for new RDNs
In contrast, the term “nutritionist” is less regulated. Requirements vary by state, with some requiring certification and others having no formal requirements. Without specific credentials, anyone can call themselves a nutritionist in many jurisdictions.
Legal Recognition and Practice Limitations
The title “dietitian” is legally protected in most states, meaning only qualified professionals can use this designation. This legal protection helps maintain professional standards and protects public health.
The regulation of nutritionists is less consistent. In some states, nutritionists without appropriate credentials may be limited in the services they can provide.
Registered dietitians can:
- Provide medical nutrition therapy
- Create custom eating plans for those with illnesses
- Work in clinical settings including hospitals
- Qualify for insurance reimbursement for services
- Prescribe therapeutic diets in medical settings
Nutritionists typically:
- Offer general nutrition advice and education
- Work in wellness centers, gyms or private practice
- Focus on preventive health and wellness
- May specialize in areas like sports nutrition or weight management
