Hey though! Maybe the -amount- of the ingredient is the key.

The pain from the pizza at Rossini's is horrible. I am not going to get their pizza anymore. Hurts too much and my gut bloats up.

However, there's very little pain to nothing really recognizable as pain from Foxy Pizza, but there is bloating.

There's a lesser amount of pain and definite bloating from Main Street Pizza.

Village Green pizza (the above-mentioned restaurant) - I get tolerable although not insignificant pain but little to no bloating.

Ridiculous. Now, the gluten-free Village Green pizza I had no pain and no bloating.

I ate the regular Village Green pizza today for breakfast and lunch. The predictable pain is here. It'll fade by tomorrow.

So, something about the mix of ingredients, I think.

(Note that I always get exactly the same kind of pizza at all of the locations.)
