In the last few years, there seems to have been a resurgence in the interest in macrobiotics in Japan. At least it does seem so judging from the magazine articles and cookbooks devoted to the subject.
If you're unfamiliar with macrobiotics, it's a form of almost-veganism (macrobiotics does allow for some fish) with quite idiosyncratic theories. It originated in Japan, was exported to the West, and gained popularity in some circles, especially the ones devoted to alternative lifestyles (like hippies and such). There's a tendency in Japan to get overly impressed by anything (or anyone) in Japanese culture that gets popular in other countries, which I think accounts for at least part of the renewed popularity of macrobiotics - or makurobi as it's abbreviated to - there. The macrobiotic diet has a lot of similarities to the traditional, or pre-WWII, diet, but isn't quite the same. It's also not the same as sho-jin cooking - elegant vegan cuisine that was originated by Zen Buddhist monks.
I've been generally trying to increase my repertoire of vegetable and grain based dishes this year (though I'm not a vegetarian), so I've done quite a lot of research into makurobi these past few months. There are plenty of very appetizing looking cookbooks coming out regularly, and I've collected quite a stack of them.
Yet it's quite unlikely that I'll be turning into a full-fledged macrobiotic convert any time soon. The main reason is that I can't fully buy into one of the central philosophies of the religion - I mean, theory - that of yin and yang foods. Basically the theory is that all foods have yin (dark or cold) and yang (light or warm) energies, and we are better off eating close to the center of the yin and yang scale. Foods that are at the center are generally things like whole grains, beans and other pulses, root vegetables (but not potatoes), and so on. Since macrobiotics did originate in Japan, brown rice is the king of grains.
