Dotsie, Christiane Northrup talks about removing all the white stuff from our diets in her book "The Wisdom of Menopause". I don't remember what she said though, so will reread and post what I find here. It will be later today, unless others can answer with more expertise than I can right now. I know there's a lot of good information out there about the why of eliminating white flour from our diets.

Here at home, we've done well at replacing white bread and white pasta with whole or multi-grain choices (except when houseguests come, but now we've decided we're not catering to any more white flour diets...they'll just have to eat what's here.) But we haven't found a brown rice that hubby likes, so haven't changed that one - yet. I'm not sure if white rice is on the same level as white flour products.
