ist dinkelmehl glutenfrei? — can a microbiome test help?

Spelt (Triticum spelta) is an ancient wheat species and contains gluten, just like all wheat varieties. It is therefore not gluten-free and unsuitable for people with celiac disease or wheat allergy. Some individuals with non-celiac gluten sensitivity may tolerate spelt better, but this is due to other grain components or FODMAPs, not because it lacks gluten. A microbiome test cannot determine whether a food contains gluten. It might theoretically hint at dysbiosis related to gluten sensitivity, but the evidence is weak. Current studies do not support microbiome tests as reliable tools for diagnosing or managing a gluten-free diet. Clinical practice relies on blood tests (tissue transglutaminase antibodies) and duodenal biopsy. Microbiome tests in this context are more marketing than evidence-based medicine. Caution: anyone who needs to avoid gluten should not rely on genetic or microbiome tests but on established diagnostics.
