Gluten is a type of protein found in certain grains like wheat, barley, and rye. It helps give bread its chewy texture and allows dough to rise by trapping air bubbles. Many people enjoy gluten in foods like pasta, pizza, and baked goods, as it contributes to their flavor and structure. However, some individuals have health issues related to gluten. For example, people with celiac disease must avoid gluten entirely, as it can damage their intestines. Others may have a gluten sensitivity, experiencing discomfort after consuming gluten-containing foods. For these reasons, gluten-free options have become increasingly popular.
