Some people have stomach problems when they eat wheat, but they don't have celiac disease or wheat allergy. This is called Non-Celiac Wheat Sensitivity (NCWS). A diet without wheat helps these people feel better, but it's hard to find a way to diagnose NCWS easily. This study explores if an ancient wheat called Triticum monococcum (TM) might be easier on the stomach than modern wheat, Triticum aestivum (TA).

The study has three goals: to see if TM makes people with NCWS feel better, to find a simple test for NCWS, and to understand how wheat affects these people. Participants will try both types of wheat without knowing which is which, and researchers will check their symptoms and health markers.

• The study lasts for several weeks with multiple clinic visits.
• Participants must be adults (18-65 years) without diagnosed wheat allergies.
• It's a double-blind study, meaning neither participants nor researchers know which wheat is being tested at any time.
