ist naturreis glutenfrei — what symptoms are typical?

The provided context does not contain information about brown rice or gluten. In general: brown rice (whole grain rice) is naturally gluten-free, as rice does not contain gluten. It is therefore suitable for people with celiac disease or gluten intolerance. Typical symptoms of gluten intolerance (celiac disease or non-celiac gluten sensitivity) include: bloating, diarrhea or constipation, abdominal pain, fatigue, headaches, skin rashes, and joint pain. In celiac disease, weight loss, iron deficiency, and damage to the intestinal lining are common. Important: brown rice may contain traces of gluten due to cross-contamination if processed in facilities that also handle gluten-containing grains. Look for certified gluten-free products. Additionally, brown rice contains more arsenic than white rice; excessive consumption should be avoided, especially in children. The evidence for these statements is based on general dietary advice and basic medical knowledge, not on the sources provided here.
