A RDN is a Registered Dietitian Nutritionist. The term “dietitian” usually refers to a RDN. A person with this credential is a food and nutrition expert who earned at least a graduate degree from an accredited dietetics program, completed a supervised practice requirement, and passed a national exam. Professional development is continued through his/her career. There are specialty credentials in the following areas: gerontological nutrition (CSG), sports dietetics (CSSD), pediatric nutrition (CSP), renal nutrition (CSR), oncology nutrition (CSO). The credentialing agency for the Academy of Nutrition and Dietetics is called the Commission on Dietetic Registration. Many states have regulatory laws for dietitians and nutrition practitioners to follow as well. RDNs can work in health care facilities, private practice, their own business, foodservice, community and public health settings, sports nutrition and corporate wellness programs, food and nutrition-related businesses and industries, universities and medical centers, or research areas.
A NDTR is a nutrition and dietetics technician, registered. A NDTR, usually with a RDN, screens, evaluates, and educates patients, manages and prevents diseases, as well as monitors patients’ and clients’ progress. NDTRs can work in hospitals, clinics, extended care facilities, home health care programs, schools, prisons, restaurants, food companies, foodservice providers, public health agencies, government and community programs, health clubs, weight management clinics, or wellness centers. To earn the credential, a two-year college degree in an approved dietetics technician program must be completed, a supervised practice experience must be completed, and a nationwide exam must be passed. NDTRs also complete continuing education courses during their careers.
RDNs and NDTRs are credentialed practitioners. A credential, a professional qualification, alerts the public that the practitioner is a trained expert in the field (nutrition and dietetics in these cases). RDNs and NDTRs are legally protected titles; therefore, only practitioners who have completed the necessary education, passed the national exam, and continue learning through ongoing education can use these titles and credentials. A “nutritionist” does not have a specific, standardized meaning though. This means that anyone can call themselves a nutritionist. Following health care recommendations from an unqualified source may cause a person harm, so the article recommends checking for credentials to ensure the recommendations are coming from a qualified nutrition expert.
