 Wheat subspecies (such as spelt, durum and Kamut) and wheat hybrids (such as triticale) also induce symptoms of coeliac disease.A small number of people with coeliac react to oats.Oats toxicity in coeliac people depends on the oat cultivar consumed because of prolamin genes, protein amino acid sequences, and the immunoreactivities of toxic prolamins, which are different among oat varieties.
