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, allergies, diabetes, and/or other medical conditions.[1] They may specialize in areas such as administrative dietetics, clinical dietetics, community dietetics, public health nutrition, or research dietetics.[2]

In fact, the main difference between a Dietitian and a Nutritionist lies in the legal limitations associated with each of these titles[3]. In Canada, Dietitians are members of a provincially regulated profession, meaning their title is protected by law, while the title “Nutritionist” is not – except in Alberta, Québec, and Nova Scotia, where “Nutritionist” is a protected title as well[4], usually used in place of the term “Community Dietitian”. Unlike Nutritionists and other Nutritional Therapists, Dietitians must meet national standards for education and training.[5]

Both Dietitians and Nutritionists may be self-employed and work as private consultants, running their own clinic. However, Dietitians are usually employed in hospitals, healthcare institutions and agencies, extended care facilities, governmental and educational institutions, and sports organizations, or may work within the food and beverage or pharmaceutical industries. Nutritionists, on the other hand, are usually working in community health centres or may act as nutritional consultants for food companies.[6][7]

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). Pediatric and/or gerontology experience are often considered strong assets, as well as proficiency in Microsoft Office Suite.
