What Is A Registered Dietitian?

To qualify as an RD, you need an honours degree in a nutrition related subject and then a further year's practical training in dietetics. Continual professional development is also required as nutrition is a forever developing science.
Hospitals, Medical Consultants and GPs can only employ nutritionists who are Registered; recognising them as the only people qualified to give valid nutritional advice. The training to become Registered includes detailed knowledge of how the body works, counselling skills, how drugs and nutrients work in the body and how to treat disease states, as well as supporting subjects such as food preparation and microbiology.
Registered Dietitians are members of the British Dietetic Association (BDA)- a royal charter holding governing body. The term 'dietitian' is now protected, so that only individuals with an RD can call themselves by this name.

All dieititians are registered with the Health and Care Professions Council and you can check out their registrations by going on to the HCPC website. health care professional logo

Why trust a Welsh dietitian?


Dietitians are the only nutrition professionals to be regulated by law and are governed by an ethical code to ensure that they always work to the highest standard.

Registered Dietitians (RDs) are the only qualified health professionals that assess, diagnose and treat dietary and nutritional problems at an individual level across hospital and community settings.  They also work at a wider public health level on the key issues of how diet and nutrition contribute to promoting population health and reducing risk of chronic disease and contribute to national and local policy.

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.


Where do dietitians work and what do they do?

Food and Nutrition are central to many aspects of the delivery of health and social care and the dietetic profession have a key role to play in both treatment and prevention of disease.

The majority of dietitians in Wales are employed by the NHS Health Boards and Trusts.  They work across hospital and community settings as part of multi-disciplinary and multi-agency teams, supporting and providing services and ensuring evidence based, consistent, quality assured nutrition and dietetic advice at both a strategic and local level. They have direct contact with patients and work through teaching and training others.


Dietitians also work in a wide range of other settings including: private practice, industry, education, research, sport, public relations, local councils and other non-government organisations. Their advice influences food and health policy across the spectrum from government, local communities and individuals.

Dietitians often work as integral members of multi-disciplinary teams to treat complex clinical conditions such as long term conditions, food allergy and intolerance, eating disorders, malnutrition, kidney failure and bowel disorders. They provide advice to caterers to ensure appropriate nutritional care of all clients in the NHS and other care settings such as care homes. They also plan, implement and evaluate public health programmes to promote health and prevent nutrition related diseases. A key role of a dietitian is to build capacity by training and educating other workers in health and social care as well as voluntary and community groups.

Dietitians are involved in research and supporting new and emerging areas of dietary treatment where close supervision is required e.g autism



In Wales, Dietitians are playing a key role in delivering on government policy across the breadth of areas from prevention through to palliative care, working at all levels and in partnership with a range of  government and non-government agencies, to address key priorities ensuring an evidence based, informed approach to the development of nutrition and dietetic practice.
