  • Dietitian : A dietitian is a regulated healthcare professional who typically holds a bachelor's degree in dietetics or a related field, has completed supervised practice (internship), and has passed a national exam. Dietitians often work in clinical settings, hospitals, healthcare facilities, and private practice. They are qualified to provide medical nutrition therapy and dietary counseling for a wide range of health conditions.
  • Nutritionist : The term "nutritionist" is more broadly used and may not be regulated in some regions. In some cases, individuals may use the title "nutritionist" without specific education or credentials. However, some nutritionists also hold advanced degrees and certifications in nutrition-related fields and may have expertise in specific areas of nutrition.

It's important to check the qualifications and credentials of a nutrition professional when seeking their services. In regions where there is no legal distinction between the terms, the qualifications, education, and experience of the individual are critical factors to consider when choosing a nutrition expert. In regulated areas, dietitians are often seen as the gold standard for clinical and medical nutrition advice due to their extensive training and credentials.

How To Become A Nutritionist: Education And Oversight?


In the field of nutrition, it's essential to understand that there is significant variation in regulation and qualifications among professionals. Unlike dietitians, nutritionists typically encounter less strict regulation, which means that individuals without formal training can legally use the title "nutritionist." However, many nutritionists opt to pursue advanced education and certification to demonstrate their expertise.

One pathway for nutritionists to obtain a recognized credential is by becoming a Certified Nutrition Specialist (CNS) through the Certification Board for Nutrition Specialists (CBNS). To qualify for this certification, applicants typically need a masters degree in nutrition or a related field, along with a minimum of 1,000 hours of practical experience. Only those who pass the CBNS exam and meet these requirements can legally use the designation CNS after their names.

Another organization, the Clinical Nutrition Certification Board, offers certification as a Certified Clinical Nutritionist (CCN) for qualified professionals.

In contrast, the path to becoming a registered dietitian (RD) or registered dietitian nutritionist (RDN) involves more comprehensive requirements, including a bachelor's degree in nutrition or a related field with approved coursework, at least 1,200 hours of supervised experience in various healthcare settings, and successfully passing a national exam administered by the Commission on Dietetic Registration. Furthermore, registered dietitians must fulfill annual continuing education requirements to maintain their board certification. The key distinction is that registered dietitians carry the titles RD or RDN after their names, signifying their completion of the rigorous educational and credentialing process.
