What does gluten-free really even mean these days?

Some people who are sensitive or allergic to gluten may need to avoid wheat, rye, and barley products because they can't digest or tolerate them. In this case, the person needs to replace wheat flour with other types of flour that doesn't contain gluten. Gluten-free foods are those that do not contain gluten, a protein found in wheat and other cereals. It entails consuming solely gluten-free whole foods like fruits, vegetables, meat, and eggs, as well as prepared gluten-free meals such as gluten-free bread and pasta.
