Dietitians are qualified experts who specialize in the science of nutrition. They assess, develop, implement, and evaluate nutrition care plans in order to improve people’s diet and eating habits, thus, ensuring a positive impact on their overall health and quality of life. Unlike Nutritionists, Dietitians also work with patients suffering from eating disorders, diabetes, and other medical conditions.

The main difference between a Dietitian and a Nutritionist is what each can legally do. In the United States, Dietitians need to have a bachelor’s degree, whose academic program is approved by the Academy of Nutrition and Dietetics' Accreditation Council for Education in Nutrition and Dietetics. Unlike Dietitians, whose title is protected by law, Nutritionists don’t have any legal restriction associated to their title, meaning that practically anyone can claim to be a Nutritionist. The title of “Dietitian” guarantees that the individual meets all of the council’s standards in terms of nutrition and dietetics.

Both Dietitians and Nutritionists may be self-employed, usually running their own clinic. However, Dietitians are often hired by government institutions dedicated to public health and welfare, as well as healthcare centers. Nutritionists, on the other hand, usually working in community health centers or in food producing companies as advisors or counselors.

Dietitians need to be licensed in order to be legally able to perform their job in the state where they choose to work. Licensing is obligatory in order to be able to use the “Dietitian” title and working without it may cause legal problems for aspirants with the Academy of Nutrition and Dietetics. Additionally, when specialized in a specific nutritional field, applicants need to be certified. Requirements for both licensure and certifications vary from state to state.

Although not a common requirement, these professionals can pursue the “Registered Dietitian Nutritionist” designation, granted by the Academy of Nutrition and Dietetics. To receive the RDN title, aspirants need to pass a national examination issued by the Commission on Dietetic Registration (CDR) as a way to demonstrate their knowledge on the field and to meet a 1,200-hour ACEND dietetic internship program.

Additional certifications on specialty fields (e.g. oncology nutrition, renal nutrition, pediatric nutrition) are available and interested parties can pursue credentials if they meet the necessary requirements.

Most Dietitian positions require a minimum of 1 to 2 years of experience working in a similar environment (e.g. within a healthcare or community setting). Voluntary work, as well as pediatric and/or gerontology experience, are often considered strong assets.
