Coeliac disease is not the same as an allergy to wheat. Coeliac disease is a well defined, serious illness where the body’s immune system attacks itself when gluten is eaten. This causes damage to the lining of the gut and means that the body cannot properly absorb nutrients from food.
Coeliac disease is not a food allergy or intolerance, it is an autoimmune disease.
Wheat allergy is a reaction to proteins found in wheat, triggered by the immune system and usually occurs within seconds or minutes of eating.
