I know I'm just showing my ignorance here, but it seems counterintuitive to me that whole grains cost more. Shouldn't they be cheaper since there's less processing involved? I understand that bread, tortillas, and other finished products made with whole grains cost more due to lower demand. But isn't it easier to leave rice brown? Doesn't plain old whole wheat flour take at least one step fewer between the silo and my pantry than the white stuff does? It shouldn't cost any more to make the grains themselves available--just take them off the assembly line earlier. I protest.
