The following cite and abstract from Medline is the most specific
description I've seen of the mechanism of "attack" on the celiac's GI tract
and of a mechanism of protection.  Anyone know any mannan-rich food stuffs?
(Maybe Moses had the right idea.  Had to get those Egyptian celiacs away
from that pernicious wheat agriculture in the Nile valley.  ...just kidding-:)!!

AB- Wheat flour and other cereals toxic for celiac patients contain an
    alcohol-soluble protein fraction that, under experimental conditions
    simulating in vivo protein digestion, yields peptides that agglutinate
    undifferentiated K 562(S) cells. In contrast, cereals well tolerated in
    celiac disease (i.e., rice and maize) do not. Furthermore, purified
    A-gliadin peptides that damage in vitro-cultured flat celiac mucosa are
    powerful agglutinins for K 562(S) cells, whereas A-gliadin peptides
    that do not show any adverse in vitro effect on celiac intestine lack
    agglutinating activity. Mannan, acetylglucosamine, and its oligomers
    (N,N'-diacetylchitobiose and N,N',N"-triacetylchitotriose) were able to
    prevent and reverse cell agglutination induced by peptides from all the
    toxic cereals. Moreover, mannan and N,N',N"-triacetylchitotriose
    exhibited a protective effect on intestinal mucosa specimens of
    patients with active celiac disease cultured with wheat protein-derived
    peptides. These data are consistent with the hypothesis that the
    agglutinating and toxic peptides are bound by carbohydrates.|
