This law provides for the licensure of dietitians, and only those with a license may provide nutrition care.
Under this law you cannot advertise or be perceived as “assessing nutritional needs of individuals and groups” etc. You also cannot do or say anything that would give the impression that you are licensed, registered, or call yourself a nutritionist or dietitian.
You can practice nutritional care as a part of self-care or gratuitous care by a friend or family member. You can also provide general nutrition information as to the use of food, food materials, or dietary supplements, as well as distribute nutrition literature, so long as you do not call yourself a dietitian or nutritionist.
If you work in the military services or federal facilities, or if you are a licensed health care, you are not restricted from performing nutritional care so long as the activities are within the scope of practice. You can market or distribute food, food materials, or dietary supplements and further explain how to use or to prepare those products.
If you are pursuing a degree in dietetics from an accredited school or program, you can practice dietetic and nutrition services if the services constitute a part of the supervised course of study. If you do partake in practices, you must be designated by a “student” or “trainee” title.
