Without "milling" (or, yes, sprouting -- but I'll leave that discussion
to the side here), grains are inedible.  Milling is chewing and
industrial milling a more effective and efficient form of chewing.  
You are right, though, that the steel roller mills that came along in
the 1880's made the bad part of the grain even more accessible by
bringning fiber-depleted wheat flour to the masses.

Avoid grains altogether, if not for the foreign proteins then for the
high carbohydrate content.
