Why spelt is wheat
Spelt is one of several ancient wheat species, including einkorn (T. monococcum), emmer (T. dicoccum), kamut/khorasan (T. turanicum), and durum (T. durum). All contain the same family of gliadin and glutenin proteins that cause celiac disease.
What the science says
Multiple studies have measured spelt gliadin epitopes in celiac patients. The result: spelt is fully reactive in celiac disease — patients show the same anti-tTG response and the same intestinal damage as with modern wheat.
Spelt typically contains 10–12% protein, of which roughly 70% is gluten — slightly less than the 75–80% gluten content of modern hard wheat. This small reduction has no clinical relevance for celiacs.
The “easier to digest” marketing
Some people without celiac or NCGS report better tolerance of spelt sourdough — possibly because of (a) slightly lower gluten content, (b) longer fermentation breaks down some FODMAPs, or (c) placebo. None of this makes spelt safe for celiacs.
Other wheat species to avoid
- Einkorn (T. monococcum) — ancient wheat, contains gluten
- Emmer / farro (T. dicoccum) — contains gluten
- Kamut / khorasan (T. turanicum) — contains gluten
- Durum / semolina — contains gluten (used in pasta and couscous)
- Triticale — wheat × rye hybrid, contains gluten
- Bulgur — cracked parboiled wheat, contains gluten
