Triticeae glutens proteins and the level of subcomponents, with bread wheat having the highest protein content and a complex mixture of proteins derived from 3 grass species ("Aegilops speltoides", "Aegilops tauschii strangulata", and "Triticum monococcum"). Triticeae seed proteins fall into four groups: Of these proteins the last two, prolamin (in wheat – gliadin) and glutelin (in wheat – glutenin) form the classically defined gluten components in wheat. Triticeae glutens are primarily important to a developing definition 'gluten-free' in dietary treatments for gluten sensitivity which are intended to exclude pathogenic proteins from the diet of susceptible individuals (namely coeliac disease). The poisonous motifs
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
