Q

Registered Dietitian/
Registered
Dietitian
Nutritionist (RD/RDN)

A

Nationally recognized and credentialed in nutrition by the Commission on Dietetic Registration. Scope of practice ranges from clinical nutrition to community, food service, and nutrition education. Some RDs are board certified in Sports Dietetics (CSSD) for advanced credentialing and specialization in sports nutrition. Although nationally recognized, some states may still require RDs to obtain state licensure prior to practicing independently or in a clinical or medical setting.

Q

Certified Nutritionist

A

It is important to determine which organization is providing the certification in nutrition and if the organization is accredited. The accredited organizations are officially recognized and authorized to provide a qualification, because they have been reviewed by other governing bodies and found to meet or exceed the minimum standards for education.
