registered dietitianA registered dietitian is a health professional that is qualified to assess, diagnose and treat diet and nutrition-related problems at an individual and wider public health level. 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 lifestyle and food choices. Paediatric Dietitians focus on the nutritional needs of infants and children from birth until 18 years of age. Only professionals who are registered with the Health Care Professions Council (HCPC) can use the title Dietitian.
