I have tried to stick with a raw food diet myself on several occasions.  It's
difficult for me, but I think it's very healthful.  Many "raw fooders" stick
with about 80% raw to 20% cooked, ex. cooked potatoes, grains.  I've eaten
many raw grains.  Can't imagine why these parents are not using them.  Having
recently moved, most of my books/old magazines are still packed, so can't
give specific info.  The Natural Hygiene Society in Florida has a magazine,
books, conferences, etc. and more than one  M.D, D.O, D.C. on board of
directors or whatever.
