If it's gluten you're allergic to, it'll make you very ill aside from acid reflux & heart burn.

My sister's girlfriend has CD, so she absolutely cannot have anything with gluten in it. When she developed CD, she just one day got extremely ill with vomiting and the runs for like 3 days and found out that was what it was.

Gluten is a protein that comes from any wheat-based product. Meat won't necessarily have it unless it's somehow breaded. Beer has gluten. Beer has gluten in it - except for Shiner Bock - they make a gluten-free version, but I think it's pretty hard to find. IDK of any other brands that make a gluten-free version.

As far as cooking/baking gluten-free, just peruse your grocery store's Organic section - they'll have gluten-fee pizza crusts, cake mixes, cookies, and stuff.

EDIT: My sister and I went gluten-free for awhile and I had so much more energy. Or well, we cut out a lot of stuff aside from gluten products, but sitll.
