I would like to know how many of us cannot eat lactose/gluten although we have been tested negative on both. I have been tested for Gluten 3 times, of which 2 were byopsies and all were negative. If I eat as much as a crumb of bread/pasta/whatever that contains gluten, I go ballistic.same with dairy. Problem is that its the same for me with maize productsAny scientific reasons why??
