Gluten-free foods are products that do not contain gluten, a protein found in wheat, barley, and rye. These foods are essential for individuals with celiac disease or gluten sensitivity, as consuming gluten can lead to various health issues. Common gluten-free grains include rice, quinoa, and corn. Many foods are naturally gluten-free, such as fruits, vegetables, meat, and dairy. Additionally, there are numerous gluten-free alternatives available, including gluten-free bread, pasta, and snacks made from alternative flours like almond or coconut flour. These options allow those avoiding gluten to enjoy a varied diet.
