ist naturreis glutenfrei — can a microbiome test help?

Brown rice (whole grain rice) is naturally gluten-free, as rice does not contain gluten. Gluten is found in wheat, barley, rye, and their hybrids. A microbiome test cannot directly determine whether someone reacts to gluten. These tests analyze gut bacterial composition, but gluten intolerance (celiac disease or non-celiac gluten sensitivity) is diagnosed through clinical methods (HLA-DQ typing, antibody tests, small intestine biopsy). The utility of microbiome tests for personalized nutrition is limited: they may indicate dysbiosis but not specific food intolerances. IgG food panels, often marketed alongside, lack clinical validity (see PMID:36933390). If you suspect gluten issues, consult a physician rather than relying solely on a microbiome test.
