I am already gluten free, I tested positive for IgA's with enterolabs last year. I guess it isnt full blown celiac, but I also have 1 genetic marker for celiac and 1 for gluten sensitivity (according to Dr. Fine).
So, autoimmunity is definitely a problem here.
I have also thought about the selenium, but again, because I am nursing, I dont want to take it. (not that I think Se if harmful itself, its just I dont want to stir up any mercury and pass it along). There was a rat study with Se supplementation and babies, and the babies did not fare well.
