ist naturreis glutenfrei — what are common causes?

Brown rice (naturreis) is naturally gluten-free because rice does not contain gluten proteins. However, cross-contamination can occur during growing, harvesting, transport, processing, or cooking. Common causes include shared equipment with wheat or barley, bulk bins in stores, and flavored rice mixes that may contain gluten-containing additives. In restaurants, rice may be cooked in broth containing gluten or served with soy sauce (which typically contains wheat). For individuals with celiac disease or non-celiac gluten sensitivity, it is advisable to choose certified gluten-free rice and check labels. The provided context does not address rice or gluten specifically; this answer is based on established clinical practice. Evidence grade: practice.
