Gluten-free diet is essential for individuals with celiac disease, non-celiac gluten sensitivity, or wheat allergy, as consuming gluten can cause intestinal damage, bloating, diarrhea, and other symptoms. It focuses on naturally gluten-free foods such as fresh fruits and vegetables, meats, fish, eggs, rice, corn, potatoes, legumes, nuts, and grains like quinoa or buckwheat. Many processed products are labeled "gluten-free" (typically containing less than 20 ppm gluten per FDA standards), but cross-contamination or hidden ingredients should be checked.
Common gluten-free food examples: rice, sweet potatoes, quinoa-based products, fresh produce, plain meats, etc.
