No need to worry. With Celiac disease, there is no such thing as "cross-reactive".
What’s with all the talk about certain types of food causing “cross-reactivity?”
There is not yet reliable data about cross-reactivity. As for the alleged possibility that many gluten-free foods or drinks (such as coffee, milk, orange juice, etc.) would trigger symptoms in celiac individuals due to hidden antigens mimicking gluten or cross-reacting with anti-gluten antibodies, it must be clearly stated that this is all false information, devoid of any scientific basis, and must be rejected as untrue.
Edit to add - I don't know what "polish wheat" is - if its a form of wheat - Celiacs should not eat it.
