Yes, I soak my rice. Books that mention this are, I believe, Healing with Whole Foods by Paul Pitchford, and the more recent, less technical "Hip Chick's guide to macrobiotics" by jessica porter. There are probably others. I don't think soaking was involved in macrobiotics years ago; I think recognition of the phytic acid in brown rice and its inhibition of zinc absorption (maybe other minerals too; i'm not sure) in the macro community is relatively recent (but i'm not sure). I know that Christina Pirello soaks brown rice due to phytic acid but doesn't soak any other grain (though there may be other macros who do). She also stopped soaking beans cause she says that when you do you lose the important enzymes! I hope this helps.
