The term "gluten-free" refers to a diet that excludes gluten, a protein found in wheat, barley, and rye. This dietary approach is essential for individuals with celiac disease or gluten sensitivity, as consuming gluten can lead to serious health issues like intestinal damage, digestive problems, and various other symptoms. Many commercially available products are now labeled as gluten-free, making it easier for individuals to find suitable options. A gluten-free diet often emphasizes naturally gluten-free foods like fruits, vegetables, proteins, and grains such as quinoa or rice.
