What is gluten?

Gluten is a protein substance that is present in certain cereals, such as wheat, oats, barley, rye, emmer, kamut, spelt and triticale. Gluten has very little nutritional value. In fact, the main function of this protein is to act as a bonding agent, that is, to cause flour to cohere, which makes possible the baking of bread.
