Dietitians are skilled and regulated health specialists that evaluate, diagnose and treat dietary and nutritional concerns at an individual and broader public-health level. They utilise the most up-to-date public health and scientific research on food, health and illness, which they decode into practical suggestions to help people make proper lifestyle and food choices. They work in private clinics and the NHS. Dieticians work with healthy and unhealthy people in a combination of settings. They can work in the catering, education, food industry, workplace, sport and the media.
