Coeliac UK is the British charity supporting people with coeliac disease and dermatitis herpetiformis, funding research and campaigning for better diagnosis and care. It provides the definitive guidance on living gluten-free: safe and unsafe foods, label reading, eating out, and avoiding cross-contamination, along with a directory of suitable products. The charity works with the food industry to improve gluten-free provision and with the health service to shorten the long average delay to diagnosis. For newly diagnosed patients, its resources turn a daunting dietary overhaul into a manageable, safe way of life.
