I think that the answer is different for different people. For example, in my case I don't think that I'll ever be able to eat gluten again, because I have one of the celiac gene markers and I think I've had celiac most of my life....way before I had Lyme. But for someone who had no gluten issues until they contracted Lyme I think that the odds are good that once the Lyme is under control they may be able to eat gluten again....or maybe not!
