I went back and re-read some and she says in one section that it IS the unprocessed bran that causes the problem. I wonder why soaking the grains wouldn't be the same as soaking the milled grain (as long as you stop it at the beginning sprout stage-like 24 hrs) and then drying it.
I also read that letting bread rise is a "fermentation" process in itself. I didn't know that. Hmmmmm...
Also, I just read that in the pioneer days they sifted most of the bran out of the flour and were left with a semi-white flour with brown specks. So most of the antinutrients (bran) were sifted out but it obviously had some nutrition in it because they lived on it.
