If he's not eat gluten or much of it, they will never find CD..

the problem with Intolerences is that we all don't react all the time..I to if I eat gluten by mistake im not gonna get sick..the problem is my intestines are getting damaged just the same..if he is sensitive to gluten then he must never eat it

..its mostly pastries, bread, pasta,..etc those can be replaced with diferent grains..
take care and, let me know
