gluten free diet,, necessary for this auto immunie disease control is avoiding all gluten, wheat, rye barley and oats,.. these foods are fine for non celiacs, just celaic disease cannot deal with them and treat these foods as invaders and shuts down the villi in the small intestine and dont alow absorbing of other minerals and vitimsn,, so often kids or adults low in many vit and minerals might have undiagnosed celiac, simple blood test can see if one has it. i use potatoe and rice and corn instead of wheat based stuff,,... so pizza is made of cauliflower or corn crust etc
