ist reis glutenfrei oder nicht — can a microbiome test help?

Rice is naturally gluten-free, as gluten is only found in certain grains like wheat, rye, and barley. However, processed rice products or cross-contamination during farming, transport, or manufacturing can introduce gluten traces. A microbiome test cannot determine whether rice contains gluten – that is a food chemistry question. Microbiome tests are often marketed to detect food intolerances, but the scientific evidence for this is weak. Celiac disease or gluten sensitivity can only be diagnosed through specific blood tests (tissue transglutaminase antibodies) and possibly duodenal biopsy. A microbiome test may indicate dysbiosis but cannot establish a direct link to gluten. The MyBody-X tests in the provided context are rated as marketing, lacking clinical validation for such claims. Therefore, for the question 'Is rice gluten-free?' rely on verified food labels, and for suspected gluten intolerance, seek medical diagnosis.
