There are products for this including beano which is supposed to be taken before eating and prevent gas build up. I've never used it but i've heard it's great. I've tried gasx which is for after you already feel bloated and while it works in one way it make my stomach feel weird in a different way and it prevents you from being able to fart which is the bodies natural defense for bloating. I would not suggest it!!! All of the above info is good info, but you may also want to consider smaller portions.
