Who can be a registered dietitian?

The correct answer is the Commission on Dietetic Registration of the American Dietetic Association. This organization is specifically responsible for the credentialing of registered dietitians. To become a registered dietitian, an individual typically needs to complete a bachelor’s degree in a related field, fulfill supervised practice requirements, and pass a national examination administered by this commission.

The other options, while related to the field of dietetics, do not hold the authority to register dietitians. The American Dietetic Association, now known as the Academy of Nutrition and Dietetics, provides professional resources and advocacy but does not directly register dietitians. The Dietetic and Food Services Association of America and the National Food and Nutritional Dietary Association are not recognized as credentialing bodies and do not play a role in the registration process for dietitians. This reinforces the significance of the Commission on Dietetic Registration in maintaining the standards and qualifications for registered dietitians.
