what karen said: i had a multitude of 'unrelated' symptoms clear up after i started the gluten free diet. just because he doesn't have digestive issues doesn't necessarily mean he is asymptomatic. migraines, joint pain, fatigue, inflammation etc and many things are misdiagnosed not to mention his immune system is in constant distress and not working correctly, so he is likely to pick up any sort of virus or whatnot and his body will not be able to fight it off (without super antibiotics, which messes up your intestinal flora) i have not been 'sick' since i quit gluten. not even a sniffle - i used to get pneumonia every year ! everybody else in my house was knocked down by the flu last year but me. ME! <the sick one, lolz, the only thing that makes me sick now is: the evil gluten
if you are feeding him, feed him gluten free chicken, mashed taters, carrots, ta da! you can find a ton of dinner ideas just search "what's for dinner" in the cooking and baking section.
