If you are diagnosed with Coeliac disease, which protein are you unable to eat?

Gluten is a protein found in foods containing wheat, barley or rye. If you have celiac disease, eating gluten triggers an immune response to the gluten protein in your small intestine. Over time, this reaction damages your small intestine’s lining and prevents it from absorbing nutrients, a condition called malabsorption.The intestinal damage often causes symptoms such as diarrhea, fatigue, weight loss, bloating or anemia. It also can lead to serious complications if it is not managed or treated. In children, malabsorption can affect growth and development in addition to gastrointestinal symptoms.For most people, following a strict gluten-free diet can help manage symptoms and help the intestines heal.
