I am  allergic to chicken, pork, beef, clam, egg, soy, barley, oat, cashew, brazil nut, and english walnut.  Could I have a protein intolerance?

What kind of allergy: Prick, blood tests not very accurate re: food allergies. Neg tests exclude an immune reaction (true allergy), but pos tests have less value.
