Registered dietitian nutritionists (RDNs) are food and nutrition experts. They assess your health and nutritional needs. They come up with plans to meet those needs. RDNs are trained to help you with a variety of food, nutrition, and health needs. These include:
Helping you lose or gain weight
Finding foods that help ease swallowing
Coming up with special diets for certain conditions. These include celiac disease, food allergies, gout, and digestive problems.
Understanding dietary changes that need to be made because of a disability
Helping with tube feeding formulas and schedules if you can’t swallow
Teaching you and your family about nutrition topics linked to diseases. Examples are diabetes and heart disease.

RDNs practice in many different settings. These include:

Fitness centers and sports programs
Culinary schools and restaurants

RDNs hold an undergraduate degree. They have completed an approved internship program and have passed a national exam. This allows them to be credentialed as registered dietitian nutritionists. Many have also earned a master's degree in dietetics, public health, or nutrition science. Beginning in 2024, a graduate degree will be the minimum degree requirement for people wanting to become RDNs.
RDNs must complete ongoing professional educational requirements to keep their registration. Some RDNs also hold other certifications in special areas of practice. These include diabetes care and education, sports dietetics, nutrition support, and oncology, pediatric, or renal nutrition.
