But don't we all in effect have intolerance to wheat/corn? If you believe
Ray's book, aren't all of us intolerant of grains? Only if we repeatedly eat
them, our immune systems accommodate them, give up the struggle.

After you have given up wheat/corn etc, and when you later  reintroduce the
foreign protein, your immune system again puts up a fight.
