Ancient wheat may be gentler on sensitive stomachs
NCT ID NCT06191432
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether an ancient type of wheat (Triticum monococcum) causes fewer stomach and other symptoms than modern wheat in people with non-celiac wheat sensitivity. Sixty-eight adults who follow a wheat-free diet will eat both types of wheat in a blinded crossover design. Researchers will track symptoms, quality of life, and look for blood markers that could help diagnose the condition.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Triticum monococcum flour (an ancient type of wheat)
- What this could lead to
- If this ancient wheat is better tolerated, it could offer a dietary option for people with non-celiac wheat sensitivity and help identify blood markers for diagnosis.
- What could go wrong
- This is a small, early-stage study (68 people) testing short-term exposure only. Results may not apply to everyone, and participants could still react to the ancient wheat.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * age \>18 and \<65 years; * negativity of class A (IgA) and G (IgG) immunoglobulin (Ig) anti-deamidated gliadin (anti-DGP); negativity of IgA and IgG anti-tissue transglutaminase (anti-tTG) and anti-endomysial antibodies (EMA) ; * absence of intestinal villous atrophy, documented in all patients carrying the DQ2 and/or DQ8 human leukocyte antigen haplotypes (therefore regardless of the negativity of celiac disease-specific serum antibodies); * absence of wheat allergy (negative prick test and/or serum IgE measurement specific to wheat, gluten and gliadin). Exclusion Criteria: * age \<18 and \>65 years; * self-exclusion of gluten/wheat from the diet and refusal to reintroduce it, for diagnostic purposes, before entering the study; * pregnancy; * alcohol and/or drugs abuse; * Helicobacter pylori and other bacterial and/or parasitic infections; * diagnosis of chronic inflammatory intestinal diseases and other organic pathologies affecting the digestive system (for example, serious liver diseases), nervous system diseases, major psychiatric disorders, immunological deficits and impairments that limit physical activity; * cancer * patients undergoing chemotherapy and/or radiotherapy.
