If you suspect a certain food is the culprit, eliminate it from your diet for a while and see if it helps. If it does, you can reintroduce the food to see if the burping starts back up. If it does, you will want to stay away from that food. If you suspect more than one food, eliminate all of them and slowly reintroduce one at a time.
