ist reis gluten — what does this mean exactly?

The question 'ist reis gluten' is German for 'is rice gluten?' It asks whether rice contains gluten. The short answer: No, rice is naturally gluten-free. Gluten is a protein found in wheat, barley, and rye, not in rice. However, cross-contamination can occur during processing or packaging. For individuals with celiac disease or gluten sensitivity, it's advisable to choose certified gluten-free rice products. The question is about dietary safety, not directly about DNA or biomarker tests, but it relates to personalized nutrition and health awareness.
