The role

Registered dietitians translate the science of nutrition into everyday information about food.

They undertake the practical application of nutrition with individuals and to promote the well-being of individuals and communities to prevent nutrition related problems. They are also involved in the diagnosis and dietary treatment of disease.

Dietitians have a wide range of responsibilities including:

  • working with people with special dietary needs
  • informing the general public about nutrition
  • offering unbiased advice
  • evaluating and improving treatments
  • educating patients/clients, other healthcare professionals and community groups.
A variety of settings

Dietitians work in a variety of areas, many of these are in hospitals or in the community. Hospital and community dietitians educate people who need special diets as part of their medical treatment including patients with:

  • kidney disease

  • diabetes

There are also opportunities for dietitians to work outside of the NHS in a variety of different areas such as:

  • food industry
  • education
  • research
  • business
  • charities

A registered dietitian needs to have an interest in science, people and food, be able to communicate with people from all areas of the community, an ability to explain complex things simply, a positive and motivating attitude and an understanding, non-discriminatory approach as well as patience and a sense of humour.
