Missouri licenses only dietitians under an exclusive scope of practice model for certain activities, specifically “dietetics practice”, including “medical nutrition therapy”. An individual must complete requirements aligned with the Registered Dietitian pathway in order to qualify for licensure. Section 324.206 of the statute, “Permitted acts by persons not holding themselves out as dietitians”,  contains exemptions and requirements before performing acts or services. In 2021, an additional practice exemption for non-RDs was added under paragraph (7), which states that a person “credentialed in the field of nutrition” is not prohibited from “providing advice, counseling, or evaluations in matters of food, diet, or nutrition to the extent such acts are within the scope of practice listed by the credentialing body and do not constitute medical nutrition therapy”. A credentialed person practicing under the exemption, but not holding himself or herself out as a dietitian, must meet specific disclosure requirements prior to performing any act or service. (See the second paragraph of section 324.206).  

The law does not preclude the practice of nutrition by those licensed in other health professions whose scope of practice includes nutrition care. Only licensed individuals may use the titles “dietitian” or the abbreviations “L.D.” or “L.D.N.”.
