Gluten Isn't The Culprit in Celiac Disease Pre-Diagnosis, Testing & Symptoms Posted September 18, 2007 · Report to Admin Well I'm still doing okay on gluten. However, I'm also still having reactions to something, and dairy is my top suspect. On Friday I ate a few small pieces of milk chocolate, and had the same gas reactions a few hours later (it feels like extra gas is getting produced in my intestines, which causes mucus to be produced as well, probably as a protective measure). But on Sunday night I had three slices of cheese pizza and only had a small reaction, which could have been from all the fat. So maybe it is lactose after all. I think I'm going to skip the lactose/whey/casein for a week or so, and then try some cheese again. If that goes well, I'll move on from there. Oh, and I did find a soy cheese at Whole Foods which doesn't have casein. I think it's called Vegan Gourmet? I haven't tried it yet since I'm still wary of soy.
