Food intolerance, please help!?

You could have acid reflux. The foods you listed are known to irritate those with acid reflux. You may have gas and bloating as well with the reflux. You could have a sensitive stomach, maybe a gluten intolerance. If you really want to know you should get checked out because you might be surprised how common some food allergies are. I was tested for celiac disease because of stomach upset, but it was negative. Good to know either way. Also, sometimes people just do not have the right amount of good bacteria in their colon and maybe you could benefit from trying Align, my doctor recommended it, for a while; I tried it and my stomach has been at peace for a while now. I would still see a gastroenterologist if it is becoming a problem. Good luck!
