Well, I always thought it contributed to gas and D, but then I was eating those Thai Noodles and they contain some casein but I didn't have a problem. This is why I'm thinking of trying the almond cheese again...even though I swore off cheese subs. Still, I had a couple of attacks a few weeks ago and that was during a time I was eating a lot of Thai Noodles...so I'm still wondering about this. Also, I'd prefer being dairy-free. I don't know! I'm a flip-flopper when it comes to dairy subs as you as can see.
