[obsessively searches for macrobiotic cookbook in kitchen...]
I discovered macrobiotics when I was trying to diet, before becoming vegan! I don't stick to it rigidly, but I do try to use organic food and wholegrains. I found the Kushi institute website quite helpful - here is the macrobiotics guide, they also have a free online libray.

OK, this is taken from 'Macrobiotic Cooking' by Michele Cowmeadow
Macrobiotics is more than a diet, it is a way of eating and living... essential macrobiotics is a way to acheive peace by regaining our individual health. Once we regain our health, of which one characteristic is understanding that we can help one another to live happily on this earth, we understand that we can recreate peace... Once we eat whole grains and cut out meat and dairy foods then the fear and anger that cause hatred between people disappears.
...
The quality of our food should be the best available to us. Grains and vegetables should preferably be organic.... In the macrobiotic way of eating we choose to eat whole grains as much as possible.
...
When we begin the macrobiotic way of eating we have to relearn the quality of the foods that we eat and how they affect us physically, mentally and emotionally. To help us do this we use a conceptual tool of classifying foods by their yin or yang nature to help re-establish our native intuition about how different foods affect us.
