Sheila,
Here's my theory on eggs and their effect on people who have MC:
Note that this is just a theory, and no medical professional I am aware of (or anyone else, for that matter) endorses or otherwise accepts this theory.
Based on the accumulated experiences of members here, I have a hunch that, similar to yeast sensitivity, egg sensitivity may be due to a type of molecular mimicry. Otherwise, there is no logical explanation for the fact that some people can eat eggs in baked goods, and/or eat eggs after sufficient healing time. Normal baking temperatures do not destroy the gluten molecule, nor any of the antigenic peptides that are part of the gluten molecule.
There is little question in my mind that molecular mimicry (or a reasonable facsimile) explains why a positive yeast antibody test result is no longer a problem for most of us after we achieve remission and our gut heals, because this phenomenon seems to be very common among members here. After seeing this same change occur over and over with members who test positive to eggs, I'm becoming convinced that eggs may follow a similar trend, though egg sensitivity appears to be more persistent than yeast sensitivity. IOW, more healing seems to be required before they lose their ability to cause a reaction.
In fact, I have a hunch that some day it will be shown that all of the food sensitivities other than gluten, are secondary to gluten, and they probably would never have occurred in the absence of gluten-sensitivity (more specifically, untreated gluten-sensitivity). Besides myself, there are one or two other members here who have managed to develop a tolerance to casein, for example. It's almost impossible to get to the point where we do not continue to produce antibodies to casein, though, because apparently the offending peptide is so similar to one of the antigenic gluten peptides, and it's almost impossible to avoid all traces of gluten these days. Even tiny traces of gluten cross-contamination are sufficient to perpetuate the production of antibodies to casein and other secondary food sensitivities. Because of that, and other reasons, I'm not going to hold my breath, waiting for the guys in the white coats to prove or disprove this theory.
