A registered dietitian nutritionist, also known as a registered dietitian, dietitian, or RD(N), undergoes extensive education and training to earn their title. They hold at least a bachelor’s degree in nutrition (starting in 2024 a master’s degree is required), dietetics, or a related field, and they must complete 1,200 hours+ of supervised practice program to gain hands-on experience. During these hours they go through many rotations such as clinical, food service, community, outpatient, pediatrics, long-term care, and more. Additionally, they pass a national registration exam to become a certified dietitian. On the other hand, the term “nutritionist” is not regulated in the same way. While some nutritionists do hold formal education and credentials, the title itself does not necessarily indicate a standardized level of training. This distinction means that anyone, regardless of their education or experience, can refer to themselves as a nutritionist.
