However I've recently been finding that I do not tolerate gluten well. After bread, pasta, beer I just feel rough - bloating and gas and cramping in the guts. Beer makes me sneeze.
Anyway I went to the doctor and was tested for celiac disease. The test came back negative, but the doctor explained that testing negative for the antibodies that would indicate celiac disease only ruled out that particular disease. The symptoms indicated a reaction to wheat, so she recommended avoiding it for a while to see how I felt. I am therefore making an effort to be gluten free. Easy usually but eating out and snacks when hillwalking or backpacking are more of a challenge.
Rusty had a good post on Wheat Intolerance. Mark Sisson's post on on Grains is also worth reading
