hat dinkelmehl gluten — what are common causes?

Yes, spelt flour contains gluten. Spelt (Triticum spelta) is an ancient wheat species with a gluten profile similar to modern wheat. Common causes of gluten-related issues include: 1) Celiac disease – an autoimmune condition triggered by gluten, strongly associated with HLA-DQB1 variants (human-strong evidence from context). 2) Wheat allergy – an IgE-mediated reaction. 3) Non-celiac gluten sensitivity – less understood, often overlapping with irritable bowel syndrome. The context does not provide spelt-specific studies, but the genetic basis for celiac is well-established. Important: For celiac disease, spelt is not safe because it contains immunoreactive gluten peptides. For sensitivity, tolerance may vary individually. Evidence for spelt-specific claims is moderate, as most data come from common wheat. Caveat: Do not self-treat suspected celiac; medical diagnosis (serology, biopsy) is required.
