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. Best test is a double-blind food challenge (neither tester nor pt know which is which, until code is cracked at end of test); cumbersome.This excludes about 90% of "allergies". Other blood tests can be used, not "live-cell"-bogus, no "applied kinesiology". ...Read more
