Registered dietitian nutritionists — RDNs — are the food and nutrition experts who can translate the science of nutrition into practical solutions for healthy living. RDNs use their nutrition expertise to help individuals make unique, 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. RDNs are advocates for advancing the nutritional status of Americans and people around the world.
Nutrition and dietetics technicians, registered — NDTRs — are educated and trained at the technical level of nutrition and dietetics practice for the delivery of safe, culturally competent, quality food and nutrition services. They are nationally credentialed and are an integral part of health care and foodservice management teams. They work under the supervision of a registered dietitian nutritionist when in direct patient/client nutrition care; and they may work independently in providing general nutrition education to healthy populations.
