Natural Celiac Disease Remedies

I wonder why any one would eat any item knowing the damage it causes?? I just lost my brother 11-05-2014 who had celiac and in which did cause lymphoma in the intestines. Yes celiac does cause other issues, liver disease, cancer, etc. etc. He had dermatitis herpatoformis along with the celiac. He was on a total gluten free diet, He grew his veggies, was extreme careful of spices, anything packages as well as the meat you buy. He was 6'2" and was skin & bones. This is a horrible disease, so why would you want to eat any gluten twice a week or even at all?? Thank You, Scarlet
