What is dietetics?

Dietetics is the study of the relationship between nutrition and health. Those who work in dietetics are called dietitians.

Dietitians apply the art and science of human nutrition to help people understand the relationship between food and health and make dietary choices to attain and maintain health, and to prevent and treat illness and disease.

The roles of a dietitian include:

  • Undertaking food and nutrition research.
  • Collecting, organising and assessing data relating to the health and nutritional status of individuals, groups and populations.
  • Interpreting scientific information and communicating information, advice and education to individuals, groups and communities.
  • Managing nutrition care for individuals by planning diets and menus, advising on nutritional needs and ways of accessing and preparing food.
  • Planning, implementing and evaluating nutrition programs with groups or populations as part of a team.
  • Managing food service systems to provide safe, nutritious food designing and implementing nutrition policies.

In Australia there is a distinction made between dietitians and other occupations in the nutrition and food science field, including that of nutritionist. All dietitians are considered to be nutritionists, however, nutritionists without a dietetics qualification cannot take on the role of a dietitian.  A dietitian has undertaken study that includes assessed professional practice in clinical nutrition, medical nutrition therapy and food service management.
