Hey, my dad had a major ulcer problem. He did take antibiotics (amoxicillin and bismuth something. Its been a while so I apologize I forgot the name). In terms of diet, I made him drink a lot of fluids and he had some fermented rice and yogurt Anything with a lot of probiotics is very good. In fact, a lot of stores sell probiotic dummies which you can try using. Broccoli is very good source too for h pylori coupled with white meat. I also faintly remember learning that lactoferrin in milk helps with h pylori infection so you could try that. The trick is clean foods coupled with a lot of fluids and medication. There isn't one magic silver bullet. Hope this helps!
