Wholewheat is the Best thing for your intestine its roughage and energy, the white bread is paste and binding giving you bowel movement problems. I use bran, wheatgerm, ground flax seed and white flour to make my bread.
Most cornmeal is already "whole grain" unless the label indicates that it's degermed. There's not much motivation to de-germ cornmeal though because all of the traditional recipes expect the flavor and texture associated with whole-kernel meal, and not some super-fine and powdery degermed variety.
... but it's nice to also whole-wheatify the flour portion. Kudos to that.
