Registered Dietitian Nutritionist (RDN)/Registered Dietitian (RD)


A registered dietitian nutritionist/registered dietitian is a food and nutrition expert who has met the academic and professional requirements to use the credential RDN/RD. The RDN credential is offered as an option for professionals who want to emphasize the nutrition aspect to the public and to other health practitioners. In addition to credentialing, many states have regulatory laws for practitioners. State requirements frequently are met through the same education and training required to become an RDN/RD.

RDNs/RDs are food and nutrition experts who can translate the science of nutrition into practical solutions for healthy living. They use their nutrition expertise to help individuals make positive lifestyle changes. They work throughout the community in hospitals, schools, public health clinics, nursing homes, fitness centers, food management, food industry, universities, research, and private practice. These professionals are advocates for improving the nutritional status of people.

Some RDNs/RDs also have certifications in specialized fields, such as sports, pediatric, renal, oncology, or gerontological nutrition.
