    Registered Dietitian Nutritionist (RDN)

    Registered dietitian nutritionists (RDNs) are food and nutrition experts. They evaluate a person’s health and nutritional needs and come up with plans to meet those needs. RDNs help healthcare providers by providing a patient treatment plan that may include the following:

    • Ideal body weight, calorie needs, and dietary needs

    • Foods that help ease swallowing

    • Special diets

    • Dietary changes that need to be made due to a disability

    • Tube feeding formulas and schedules for people who can’t swallow

    • Patient and family education on nutrition topics linked to diseases, such as diabetes

    RDNs may practice in different settings, including:

    • Hospitals

    • Inpatient rehabilitation centers

    • Home health settings

    • Private practice

    • School districts

    • Community or government nutrition programs

    RDNs hold an undergraduate degree, have completed an approved internship program, and have passed a national exam to be credentialed as Registered Dietitian Nutritionists. Many have also earned a master's degree in dietetics or nutrition science.
