Dieticians promote a healthy lifestyle in their clients and treat medical conditions by providing impartial nutritional advice and devising eating plans based on the science of nutrition.

They are health professionals qualified to provide practical information to promote healthy eating and help in the treatment of disease. Dieticians use the most up to date public health and scientific research on food, health and disease, which they translate into practical guidance to enable people to make appropriate lifestyle and food choices. They apply knowledge of food, nutrition and other related disciplines such as biochemistry, physiology and social science to promote health, prevent disease and aid in the management of illness.

Dieticians can find employment in areas such as research and education, sports, private practice, policy development, advocacy and the media. However their main employment areas are in hospitals, working in collaboration with doctors, in doctor surgeries and community centres, or within business and industry, working directly with food manufacturers and pharmaceutical companies.

Career development

As clinical experience grows, so too do opportunities to move into more senior posts and to specialise in a particular area such as: diabetes, children’s health, cancer or surgery. Those interested in management may be interested in supervising the planning and preparation of meals in hospitals, prisons, schools, and work based cafeterias. In addition to developing menus, they are also involved in the hiring and training of staff and offer expert advice in budgeting and planning healthy meals, food safety management systems such as HACCP (Hazard Analysis Critical Control Point).

As well as the traditional hospital-based career path, a smaller number of dieticians are employed by food manufacturers, while others move into research and teaching.
