Accredited nutritionists (AN) are tertiary-qualified nutrition professionals who have expertise in a range of nutrition services. These may include areas such as community and public health nutrition, nutrition research and education related to nutrition, but they have no qualifications in individual dietary counselling, group dietary therapy or medical nutrition therapy. Depending on their area of work, some dietitians call themselves nutritionists. All accredited practicing dietitians (APDs) are nutritionists, but not all nutritionists are APDs.
