I have the same issue with hot sauce and other spicy foods. That is not because of an allergy, though. Spicy foods bother us because the capsasin in the peppers burns. And I guess most of that stuff normally get absorbed in the colon before it comes out.
There is a solution for the spicy foods, though. Actually two things:
Milk and a supplement called Prelief. The proteins in the milk coat the capsasin molecules and deactivate them. When you eat something spicy, drink milk or eat ice cream as soon as possible and it won't hurt coming out the other end.
Prelief helps more with acidic foods if that bothers you. Things like lemon juice or tomato sauce. It's a pill that you take with your meal and it neutralizes the acid. I'm not sure what's in it. I think is has some kind of calcium in it. You can get it on Amazon.
As for the peanut issue, I'm fine if I eat peanut butter. It's just when I eat a large amount of roasted peanuts, that it bothers me, so I can't have those.
