I am having a very hard time findng a food (for my tube) that doesnt cause horrible gas and bloating. Ensure makes my stomach hurt, boost is okay but still makes me uncomfortably gassy. The nutritionist just put me on ultra cal, that one is an absolute no!! Does anyone have any suggestions that I could talk to the nutritionist about. I am lactose intolerant, and I know that most foods are lactose free, but maybe they arent as lactose free as they say. Any suggestions? I've lost 50 pounds since January.
