Every time after finishing pizza (both homemade and store-bought), I get stomach pain and diarrhea about 2 hours later. After going to the toilet 1–2 times, it usually goes away.
This didn’t happen in the past. I was thinking it could be the tomato sauce, but I’m not sure since I’m fine when I eat regular pasta with tomato sauce. However, I have never tried whole wheat pasta with tomato sauce.
Because every time I made whole wheat pasta salad with fresh cherry tomatoes (home-grown), my stomach would hurt. When I didn’t add cherry tomatoes, I was fine.
Also, I’m fine when I eat bread made from the same kind of flour.
Does anyone else have the same experience?
