- Qualification Examination: Only after passing the national or regional registration examination can you obtain the title of “Registered Dietitian” (RD/RDN).
- Continuing Education: Continuing education must be completed regularly to ensure that professional knowledge keeps pace with the times.
2. Nutritionist
- Broad definition: In some areas, “nutritionist” is not a title strictly protected by regulations, and anyone interested in nutrition can call themselves that.
- Differences in certification: Some states or countries require nutritionists to obtain specific certifications (such as CNS), complete relevant courses, internships, and pass exams.
- Professional ability: Certified nutritionists can provide nutrition consultation and some medical nutrition services, but uncertified ones mainly provide health education.

5. How to choose the right nutrition professional
- Medical needs: If disease management or special medical needs are involved, registered dietitians should be given priority.
