After 40 years of Crohn's (now in remission) I feel somewhat qualified to add to this. Here are a couple of things I have learned: I can eat nuts and larger seeds if I chew them well. The smaller seeds like cucumber or immature watermellon seeds, I cannot. Best to leave them off of things I can eat. Vegatables are best cooked, forget raw vegies. Swanson Foods makes a great probiotic called Epic Pro with 25 different species. After much research as a Microbiologist it seems to be a "good bang for the buck." I am afraid that pop corn isn't something I can eat (and I really miss it!). Best to avoid it. I don't know how many of these apply to you but please start avoiding pop corn.
