Your reaction to casein is not so surprising . . . if you do the tests through Enterolab you will probably find out that you cannot tolerate gluten or casein (a milk protein that is very similar in composition to the protein structure of gluten). This is my first reply to this group, however I have been reading everyone's stories for months - it is the only thing that has kept me from thinking that I am going crazy. My brother was diagnosed with Celiac a year ago through a biopsy. I didn't know much about the disease, so I started to do some reading. SURPRISE - I found myself connecting to many of the stories of people suffering atypical symptoms. I went on a gluten and casein free diet on January 1, 2007. Within 2 weeks I felt better than I have ever felt - I mean GREAT! I have lost 35 lbs in the last few months, still have 30 to go. It seems that I am one of those who GAIN weight with gluten intolerance. The psoriasis on my face and arms went away within two weeks of the diet change. I now know that I have been glutened because I get blisters on the inside of my nostrils that pop and scab over almost within 4 hours of the gluten intake. I could go on for hours with all the ways that the change in diet have helped me. Based on my positive results with the elimination diet and my brother's positive diagnosis, I asked my children's ped to test them for Celiac. I got the typical "are you crazy" look and reaction from an uneducated health professional. She reluctantly ran the blood panel, and, as she suspected, it was negative. I proceeded to have them tested through Enterolab. My 3 year-old's results are back, and she IS gluten and casein intolerant, does not have full blown Celiac. We are waiting on my 7 year-olds results, however I anticipate that she is also gluten and casein intolerant based on past health issues. Both children have been on gluten and casein free diet since the day after we took their samples to be mailed to Enterolab. They are already showing the benefits of a 'healthy' diet for them. Their peditrician will not acknowledge the test results and thinks I am totally nuts to put them on a 'restricted' diet for 'no reason.' SHE obviously has not suffered from food intolerances as I have - why would I put my children through all the problems I have been through. Anway, long post to say . . . stick with it. You are not crazy - you know how you feel when you do/do not eat certain foods. Learn to listen to your body, it will not steer you wrong. AND strongly encourage your family members to be tested. They are suffering needlessly.
