Do vegetables give you stomach problems more than other foods?

I have LPR.

When I eat a vegetable like spinach or string beans, I get a stomach ache.

But I can eat a slice of pepperoni pizza or burger and fries and my stomach won't bother me.

Has anyone else experienced something like this?

 

I have the same problems, but for me cooked vegetables seem to really improve my symptoms. Although vegetables like spinach are very gas producing. You guys might want to check out food intolerances/sensitivities. Vegetables and fruit contain natural chemicals called amines and salycilates which are known to be problematic for some people. Unfortunately the only way to test for them is to go on an elimination diet which is quite tedious.
