Gluten the final product with a chewy texture. Wheat, barley, rye and oat prolamins are respectively known as gliadins, hordeins, secalins and avenins; these protein classes are often collectively referred to as gluten. Wheat glutelins are called glutenin. True gluten is limited to the grains listed above. The storage proteins in maize and rice are sometimes called glutens, but they differ from true gluten. In a small part of the general human population, gluten can trigger adverse autoimmune reactions responsible for a broad spectrum of gluten-related disorders, including coeliac disease, non-coeliac gluten sensitivity, gluten ataxia and dermatitis herpetiformis. People with these
Non-celiac gluten sensitivity in gluten and gluten-containing cereals (wheat, rye, barley, and their derivatives) may have a role in the development of symptoms. FODMAPs are present in gluten-containing grains and have recently been identified as a possible cause of gastrointestinal symptoms in NCGS patients, but do not justify extra-digestive symptoms. For these reasons, NCGS is a controversial clinical condition and some authors still question it. It has been suggested that "non-celiac wheat sensitivity" is a more appropriate term, without forgetting that other gluten-containing cereals are implicated in the development of symptoms. NCGS is the most common syndrome of gluten-related disorders with prevalence rates
