I'm not a physician, but I wouldn't think that stopping those things would give you diarrhea and gas. It's excellent that you stopped them! Maybe you're taking some new medication or vitamin supplement? Taking too much iron for example could cause diarrhea. (or pomegranate juice can cause it too because of the iron in it) So, I think you should investigate what you're eating or ingesting and see how that affects it. Another possibility, maybe you eat milk products but have became lactose intolerant? It can develop even if you didn't have it earlier. Good luck!
