This law protects titles and contains broad exemptions that further protect the right of anyone to provide nutrition care.
Section 326-H:2 states, among other things, that:
The state of New Hampshire “ recognizes that there are many aspects of nutrition and it is not the purpose of this act to restrict the ability of any person to provide advice, counseling, or assessments in matters of food, diet, or nutrition and to receive compensation for such services, thereby assuring that all persons can obtain nutrition and dietary information, dietary counseling, and information regarding food, food products, dietary supplements, and their proper use, from any source of that person’s choosing. The purpose of this act, therefore, is to establish regulations and standards of qualification, training, and experience for individuals who are practicing dietitians.”
Additionally under Section 326-H:4(II) the law states:
“Nothing in this chapter shall be construed to restrict, prevent, or otherwise interfere with a person who does not hold himself or herself out as a licensed dietitian from providing advice, counseling or assessments in matters of food, diet or nutrition; or from marketing or distributing food products, including dietary supplements as defined by the federal Dietary Supplement Health and Education Act; or from providing explanations to or communicating with customers with regard to the uses of such products.”
So long as you are not using protected titles “licensed dietitian” or the abbreviation “LD” you may practice up to the level of your education and training.
