Welcome to HW.com!!! How long have you had your ostomy? Ileostomy or colostomy? (Sorry for the questions...)
After a period of healing and recuperating, you will be able to introduce those taboo foods slowly to your diet. So, don't give up on them, just take a vacation from them. There are certain things that you may not be able to eat, and there are certainly some which you need to be careful trying at first to be sure that they won't cause a problem. If I feel something may bother me, then I do a couple of things: eat other food with it and don't eat it on an empty stomach, chew it very well as you should all of your food and esp. fiber/roughage, and drinks lots of fluids.
Best of luck to you and keep checking out HW.com. See ya later,
