Does anybody know what to avoid eating with peptic ulcers?

Yesterday , I pigged out on beef stew with rice. The day before I had a chopped ham casserole with pasta and cream of chicken soup. This morning at 3am I became sick again, and ran to the bathroom until 6am. I think my colon is completely cleaned out. I’m sleepy but I don’t have chills , nausea or fever.
Did those recipes do this to me? I had been back on the treadmill , cooking and doing laundry and now this happens. TIA
