Final answer:
Registered dietitians and nutritionists are different. Registered dietitians have specific education and training requirements, while nutritionists have a wide range of educational backgrounds and certifications.
Step-by-step explanation:
Registered dietitians and nutritionists are different. Registered dietitians are professionals who have completed education and training requirements to become accredited by the Commission on Dietetic Registration (CDR). They have a bachelor's degree in dietetics, food science, or a related field, and they must also complete a supervised internship program and pass a national exam.
Nutritionists, on the other hand, can have a wide range of educational backgrounds and certifications, and there is no standardized qualification or regulation for this title.
