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 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[1], usually used in place of the term “Community Dietitian”. Unlike Nutritionists and other Nutritional Therapists, Dietitians have more strict regulations regarding education and licencing.[2]

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 centres. Nutritionists, on the other hand, are usually working in community health centres or in food producing companies as advisors or counsellors.[3][4]
