I don't eat wheat, oats, barley or rye. Unless its beer. I can cope with the beer effects. It's worth it.

One cheerio, and I'm on the floor in agony.

Even the wheat in licorice gets me ill. (yes, there is often wheat flour in licorice candy)

I sometimes wonder how much "IBS" is actually gluten enteropathy, cuz so many of the symptoms sound the same.

Gluten intolerance/enteropathy/celiac disease/celiac sprue commonly ties in with a thrilling inability to absorb vitamin B12 properly. Even taking 20x the normal amount of B12 a day, my blood levels are only half the average value. Quite a few of the effects of low B12 are digestive symptoms.

Gluten and B12 issues are so prevalent in my family that my doc didn't even bother to test me. Chow down on that methyl cobalimine and don't eat grains!
