What is a dietitian?

Registered dietitians are qualified health professionals that assess, diagnose and treat diet and nutrition problems at an individual and wider public health level. Uniquely, dietitians 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.

Dietitians are statutorily regulated, with a protected title and governed by an ethical code, to ensure that they always work to the highest standard. The spectrum of environments in which dietitians practise is broad and includes the NHS, private practice, industry, education, research, sport, media, public relations, publishing, non-government organisations and national and local government. Their advice influences food and health policy across the spectrum from government to local communities and individuals.

The title 'dietitian' can only be used by those appropriately trained professionals who have registered with the Health Care Professions Council and whose details are on the HCPC website. We have a leaflet that explains the roles of nutrition professionals further.
