There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone who saw this today donated $5, we would meet our goal for 2020.

Macrobiotics (from the Greek for "long life") is a diet and lifestyle created originally by Japanese writer and guru Nyoichi Sakurazawa (櫻澤如一), better known under the pen name George Ohsawa, and popularized in Western countries by his student Michio Kushi and others. Essentially, the macrobiotic way proposes to break the foods consumed by human beings down into yin and yang according to some arbitrary scheme, then balance out the diet into yin and yang foods and thereby achieve significant life extension.
While meat is not banned from macrobiotic meals, it falls into the category of foods that are "extremely yin", i.e. "stagnating", while alcohol, fermented foods, and some spices are considered "extremely yang" or "overstimulating". Many macrobiotic practitioners are therefore either partially or wholly vegetarian. Much macrobiotic food tends to be essentially vegetarian Japanese food, though that need not be the case.
Oddly enough, despite its claims to promote longer lives, neither the founder, Ohsawa, nor Michio Kuchi's wife Aveline (a noted author in the macrobiotic movement in her own right) had a longer than average lifespan; Ohsawa died of heart disease at age 72, and Aveline Kushi of cervical cancer, even as Ohsawa promoted macrobiotics in part as a cancer prevention diet.
While Ohsawa focused on diet as a means by which to promote health, he was a heavy smoker. He even stretched macrobiotic precepts to suggest that the blue or gray smoke coming out the front of a cigarette is yin (cancer-causing), while the yellow or orange smoke coming out the back that the smoker breathes in is yang, which obviously flies in the face of all we know about the dangers of smoking.
