Hello Hans,
looking briefly at some of your other posts, I see that you're in Germany - so you can't order from the shop here, but you can read what's written on the description of this book:
"#7 Diet, An Accompaniment to Ohsawa’s Zen Macrobiotics"
and perhaps find the book in your area.
And there are some on this forum who have experience with the rice diet, so hope they can help.
I also have no idea what refined vegetables could possibly mean, but I do know it was posted here to go off the rice diet slowly, perhaps adding just a few foods at a time.
How are you feeling???
