Allergic to wheat, but not gluten

Through blood tests, my friend learned that she is allergic - not merely
sensitive - to wheat but not gluten. Many books suggest alternatives
(amaranth, buckwheat, millet, montina, quinoa, sorghum, teff, etc). But
without knowing specifically which component of wheat a person is
allergic to, how can one be sure that that component isn't also present
in a "safe" alternative?
