But gluten eaten?
Gluten intolerance is the cause of celiac disease (also sprue) and gluten sensitivity. The latter is also known as non-immune and non-autoimmune gluten sensitivity (non-celiac nonwheat allergy gluten sensitivity).
In celiac disease, lifelong adherence to a gluten-free diet (GFD) is of great importance. Strict adherence to the GFD can help the gut recover, prevent complications and improve quality of life.
Especially when visiting restaurants or traveling, it is not always possible to adhere to the strict diet, as even supposedly grain-free products may contain gluten or the gluten content of the meal cannot be ascertained.
