ist reis glutenfrei — what does this mean exactly?

Yes, rice is naturally gluten-free. Gluten is a protein found in wheat, barley, rye, and their hybrids – not in rice. Therefore, plain, unprocessed rice is safe for people with celiac disease or gluten sensitivity. However, processed rice products (e.g., rice noodles, rice cakes, ready meals) may be cross-contaminated with gluten during growing, transport, or manufacturing. Some rice-based products may also contain added gluten as a binder or thickener. For a strict gluten-free diet, it is advisable to choose products labeled 'gluten-free' or certified by a recognized organization (e.g., the Gluten-Free Certification Organization). The statement 'rice is gluten-free' is correct in principle, but practical caution is needed. The evidence is strong, based on clinical practice and food labeling regulations (e.g., EU Regulation 828/2014).
