According to the Dietitian’s Association of Australia, a nutritionist is a tertiary qualified nutrition professional that has the expertise to provide a range of evidence-based nutrition services related to nutrition, public health nutrition, policy and research, and community health. There is no industry specific assessing authority that assesses the qualifications of nutritionists who are not dietitians.
Dietitians are also qualified to provide this range of evidence-based nutrition services, but in addition, dietitians have the expertise to provide individual dietary counselling, medical nutrition therapy, group dietary therapy and food service management. A dietitian has undertaken a course of study that included substantial theory and supervised and assessed professional practice in clinical nutrition, medical nutrition therapy and food service management.
