Jon Lewis asked about the dairy/egg connection.  I think that some
people who are allergic to milk are also allergic to eggs...not because
the foods are necessarily related nutritionally, despite that
old-fashioned food group chart that Roberta alluded to.  I think these
foods, along with wheat, soy and nuts are such common allergens,
especially with children, it seems that many folks are concerned with
avoiding them.  Our doctor told us that if another allergy were to
develop, it would probably be soy or eggs.
