You'll find everyone is different. Some people will tell you to stay away from popcorn, peanuts, corn, mushrooms, etc and others will tell you they eat all those foods and more without a problem. It's really a matter of experimentation.
Try introducing new foods, one at a time and CHEW, CHEW, CHEW! That way, if a food does cause you problems, you can identify the culprit and either limit it or totally eliminate it from your diet as needs be.
Please do NOT stay away from a certain food just because it affects someone else adversely. Chances are you will be able to eat that same food without a problem at all.
Good luck Matt.
