I was recently suggest by a doctor to test for gluton allegy, he thinks it may explain some of the illness I've experienced in the last few years. I than talked to a friend who has been dignosed as allegic to gluton and has been on gluton free diet for al most a year now. She admits its hard and a long jounrey. What exactly is gluton-free diet? Does it mean no more bread for me? Is gluton really the root cause of some many problems as my google search has suggested?
