My DH gets Asthma if he is exposed to airborne wheat or milk (such as from boiling wheat pasta or mixing wheat flour in something for a recipe, or from boiling milk). He also cannot eat wheat or milk without getting "intestinal anaphylaxis" (severe swelling everywhere the milk/wheat touches from his mouth on down..., nausea, profuse vomiting, diarrhea).
I myself have Gluten Sensitivity and so must avoid all wheat/rye/barley and also I have an oat allergy so I have to avoid oats as well. My symptoms are not as violent as my DH's are, but I suffer for weeks to months after an accidental exposure (even from airborne gluten). I have no problem with airborne milk, but don't do well if I consume a lot of dairy...it is hard for me to give up completely, though, given all my other food sensitivities/allergies & intolerances...so I still enjoy organic cheeses.
Here are some resources to help with alternative foods to dairy & wheat (and no, bran or oat flour may not be safe either...oats must specify that they are gluten free or else they will likely contain lots of wheat cross-contamination from grain storage facilities in the USA):
