<<Disclaimer: Verify this information before applying it to your situation.>> I recently discovered I had a problem with grapes. I notice in looking at the CELIAC archives, a couple of old messages from people who also had similar problems, but nothing recently posted, so I thought I would post my story in case it might help others. I had been avoiding grapes and raisins for a long time, thinking they did cause a problem. However, I still used grape jam (health food store brands), and juices that contined some grape juice (white). I didn't think these could causes major problems, because they weren't pure grapes. What led to a real problem was switching to juices that contained grape skin, for coloring. That led to many months of bouts of severe diarrhea, and constantly changing my diet. I never assumed it was the juice, because I always greatly diluted it. Finally, when I went on a trip, and my digestive tract because normal, I realized the source of my problem. So, hope this helps someone out there. Mark *Support summarization of posts, reply to the SENDER not the CELIAC List*
