in this case, google "special carbohydrate diet". It is a diet which got invented for people with huge bowel problems like H pylori, crohns and IBS. The goal in this diet is to a) kill bacteria by starving them, but not you, b) get some easy digestible nutrients back into you, c) get the inflammation down and d) change the bacterial flora so no bad bugs can survive.
Give it a test run for 1 month, and if it is not helping, you can always go back. It is also important that you tweak the diet so it suits your needs. If Honey gives you pain, kick out the honey. If you hate spinach, but love pumpkin, just switch.The diet is in guidelines, not rules.
It is however very important that you start with the intro diet, and most of the things during the first phase of the diet (for the phases look on pecanbread.com) is cooked to mush for better digestion, so it should be most gentle for your stomach.
Good luck, hang in there!
