Here are a couple of essays that may help. They were written by Dr. Lewey who is a board certified GI doc.
The first is about cross reaction between pollen allergies and food allergies:

This next essay is about heartburn/reflux and CD/GS. What is interesting is that Dr. Lewey mentions that he was diagnosed as gluten sensitive through Enterolab and is now GF.

I hope the help with the expense of the food works out.
