Tennessee is an Exclusive Scope of Practice State. The law requires a license to provide nutrition care, and only dietitians may obtain a license. This law prevents holistic nutrition professionals from assessing the nutritional needs of individuals or groups of people. You may not state or imply that you are licensed, registered, or certified by the state or use the protected title of “dietitian,” “nutritionist,” “licensed dietitian,” “licensed nutritionist,” “L.D.,” or “L.N.” There are exemptions for holistic nutrition professionals which will allow you to practice in the state of Tennessee.
(b) Nothing in this chapter shall be construed to affect, prevent or restrict:
(1) Persons qualified and licensed to practice other health professions from engaging in the practice of dietetics/nutrition when incidental to the practice of their profession. This chapter shall in no way apply to persons licensed to practice medicine or osteopathic medicine pursuant to chapters 6 and 9 of this title;
(4) Persons performing the activities and services of a nutrition educator in the employment of a federal, state, county or municipal agency or an elementary or secondary school or accredited degree granting educational institution, insofar as such activities and services are part of a salaried position;
(5) Federal, state, county or local employees involved with nutrition-related programs, including, but not limited to, the cooperative extension service, child nutrition programs and Project Headstart from engaging in the practice of dietetics/nutrition within the discharge of their official duties; provided, that any such person engaging in dietetic/nutrition practice outside the scope of such official duty must be licensed as provided in this section;
(6) Persons employed in a hospital or nursing home as defined in § 68-11-201 and subject to licensure by the Tennessee board for licensing health care facilities; or
(7) Persons who do not hold themselves out to be licensed and/or registered dietitians/nutritionists of the right to provide services and information related to non-medical nutrition while:
(A) Employed by or operating a health weight loss or fitness program;
(B) Employed by or operating a health food store;
(C) Employed by or operating a business that sells health products, including dietary supplements, food or food materials, or provides non-medical nutritional information or distributes nutritional literature; or
(D) Conducting classes or disseminating information related to non-medical nutrition. Non-medical means engaging in any practice that does not constitute the practice of medicine, osteopathy, chiropractic, dentistry or podiatry.
