Gluten is a protein found in certain grains, particularly wheat, barley, rye, and spelt. It matters because some people have celiac disease or gluten sensitivity and must avoid it for their health, while others simply choose to limit their intake for various reasons.

Gluten is a structural protein complex naturally found in certain cereal grains. The term gluten usually refers to the elastic network of a wheat grain's proteins, gliadin and glutenin primarily, which forms readily with the addition of water and often kneading in the case of bread dough. The types of grains that contain gluten include all species of wheat (common wheat, durum, spelt, khorasan, emmer, and einkorn), and barley, rye, and some cultivars of oat; moreover, cross hybrids of any of these cereal grains also contain gluten, e.g. triticale. Gluten makes up 75–85% of the total protein in bread wheat.
