Conceptual basisEdit

File:Yin yang.svg
Macrobiotic diets are based on the concept of balancing yin and yang.<ref name=zen-ten/>

The macrobiotic diet is associated with Zen Buddhism and is based on the idea of balancing yin and yang.<ref name=oxref>Template:Cite book</ref> The diet proposes ten plans which are followed to reach a supposedly ideal yin:yang ratio of 5:1.<ref name=zen-ten>Template:Cite book</ref> The diet was popularized by George Ohsawa in the 1930s and subsequently elaborated on by his disciple Michio Kushi.<ref name=ACS/> Medical historian Barbara Clow writes that, in common with many other types of quackery, macrobiotics takes a view of illness and of therapy which conflicts with mainstream medicine.<ref name=clow>Template:Cite book</ref>

Macrobiotics emphasizes locally grown whole grain cereals, pulses (legumes), vegetables, edible seaweed, fermented soy products, and fruit combined into meals according to the ancient Chinese principle of balance known as yin and yang.<ref>William Dufty with Nyoiti Sakurazawa (1965) You Are All Sanpaku, University Books.</ref> Some macrobiotic proponents stress that yin and yang are relative qualities that can only be determined in a comparison. All food is considered to have both properties, with one dominating. Foods with yang qualities are considered compact, dense, heavy, and hot, whereas those with yin qualities are considered expansive, light, cold, and diffuse.<ref>Porter, pp. 22–25</ref> However, these terms are relative; "yangness" or "yinness" is only discussed in relation to other foods.<ref>Porter, pp. 44–49</ref>

Brown rice and other whole grains such as barley, millet, oats, quinoa, spelt, rye, and teff are considered by macrobiotics to be the foods in which yin and yang are closest to being in balance. Therefore, lists of macrobiotic foods that determine a food as yin or yang generally compare them to whole grains.<ref>Porter, pp. 71–78</ref>

Nightshade vegetables, including tomatoes, peppers, potatoes, and eggplant; also, spinach, beets, and avocados, are not recommended or are used sparingly in macrobiotic cooking, as they are considered extremely yin.<ref>Kushi and Jack, p. 119.</ref> Some macrobiotic practitioners also discourage the use of nightshades because of the alkaloid solanine which is thought to affect calcium balance.<ref>Stanchich L "All About Nightshades". New Life Journal: Carolina Edition, Apr/May 2003, vol. 4, no. 5, p. 17, 3 pp.</ref> Some proponents of a macrobiotic diet believe that nightshade vegetables can cause inflammation and osteoporosis.<ref>Porter</ref>

HistoryEdit

Macrobiotics was founded by George Ohsawa and popularized in the United States by his disciple Michio Kushi.<ref name="Barrett 1993">Template:Cite book</ref> In the 1960s, the earliest and most strict variant of the diet was termed the "Zen macrobiotic diet" which claimed to cure cancer, epilepsy, gonorrhea, leprosy, syphilis and many other diseases.<ref name="Barrett 1993"/><ref name="CA 1993"/> Ohsawa wrote that dandruff is "the first step toward mental disease".<ref name="Barrett 1993"/> Ohsawa wrote about the diet in his 1965 book Zen Macrobiotics.<ref name="CA 1993"/> The Zen macrobiotic diet involved 10 restrictive stages with the highest stage eliminating all foods in the diet apart from whole grains. Fluid intake was discouraged at all stages.<ref name="JAMA 1971">Template:Cite journal</ref><ref name="Barrett 1993"/>

In 1965, a young follower of the macrobiotic diet had died from malnutrition.<ref name="Barrett 1993"/> George Ohsawa was sued for malpractice and the Ohsawa Foundation in New York was closed after a raid by the Food and Drug Administration. In 1966, a Grand Jury who reviewed several cases of death from malnutrition among macrobiotic proponents concluded that the diet "constitutes a public health hazard".<ref name="Barrett 1993"/> In 1967, the first case report of scurvy on the macrobiotic diet was reported.<ref name="Barrett 1993"/> In 1971, the American Medical Association's Council on Foods and Nutrition commented that followers of the diet were in "great danger" of malnutrition.<ref name="Barrett 1993"/> Their report concluded that "when a diet has been shown to cause irreversible damage to health and ultimately lead to death, it should be roundly condemned as a threat to human health".<ref name="CA 1993"/><ref name="JAMA 1971"/>

After the Ohsawa Foundation in New York was closed, Michio Kushi shifted operations to Boston, where he opened two macrobiotic restaurants.<ref name="Barrett 1993"/><ref>Template:Cite news Template:Subscription required</ref> In the 1970s, Kushi established the East West Journal, the East West Foundation and the Kushi Institute. In 1981, the Kushi Foundation was formed as a parent organization for the institute and magazine.<ref name="Barrett 1993"/> The Kushi Institute was located on a large site in Becket, Massachusetts where it hosted macrobiotic conferences, lectures and seminars. Kushi combined macrobiotics with numerous paranormal and pseudoscientific ideas including auras, astrology, chakras, oriental physiognomy, palmistry and extra-terrestrial encounters.<ref name="Barrett 1993"/> The Kushi Institute closed in 2017.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

PracticesEdit

FoodEdit

File:Some Basic Macrobiotic Ingredients.JPG
Some basic macrobiotic ingredients

The macrobiotic diet is considered an unconventional or fad diet.<ref name=fad/><ref>Template:Cite journal </ref> Some general guidelines for the macrobiotic diet are the following.<ref name="CA 1993"/>

  • Whole cereal grains, especially brown rice: 50–60%
  • Vegetables: 20–30%
  • Beans and sea vegetables : 5–10%

Small amounts of white fish and fruit may be eaten if desired. Nuts and seeds are not often consumed but are permitted as occasional snacks if they are lightly roasted.<ref name="CA 1993"/> Beverages include herbal teas, cereal-grain coffee and roasted-barley tea.<ref name="CA 1993"/>

KitchenwareEdit

Cooking utensils should be made from certain materials such as wood or glass, while some materials including plastic, copper, and non-stick coatings are to be avoided.<ref name=fad/> Electric ovens should not be used.<ref name=fad>Template:Cite book</ref>

CancerEdit

The macrobiotic diet has been advertised as an alternative cancer treatment but is ineffective to treat any type of cancer.<ref name="CA 1993">Template:Cite journal</ref><ref>Stare, Fredrick John; Whelan, Elizabeth M. (1998). Fad-Free Nutrition. Hunter House Inc. p. 127. Template:ISBN "There is no scientific evidence that macrobiotic diets can be helpful for cancer or any other disease."</ref> Macrobiotics author Michio Kushi argued that conventional cancer treatments are "violent and artificial" and the macrobiotic diet should not be combined with conventional treatment.<ref name="CA 1993"/> There is no clinical evidence to support the cancer claims of macrobiotic proponents.<ref name="CA 1993"/> The American Cancer Society who reviewed 11 scientific data bases found no peer-reviewed evidence that the macrobiotic diet is effective for treating any type of cancer.<ref name="CA 1993"/> The Office of Technology Assessment, examining both published and unpublished macrobiotic literature, failed to verify any claims of cancer cure.<ref name="CA 1993"/>

The American Cancer Society recommends "low-fat, high-fiber diets that consist mainly of plant products"; however, they urge people with cancer not to rely on a dietary program as an exclusive or primary means of treatment.<ref name=ACS>Template:Cite book</ref> Cancer Research UK states, "some people think living a macrobiotic lifestyle may help them to fight their cancer and lead to a cure. But there is no scientific evidence to prove this."<ref name=cruk>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

SafetyEdit

RegulationEdit

Macrobiotic practitioners are not regulated, and need not have any qualification or training in the United Kingdom.<ref name=cruk/>

ComplicationsEdit

One of the earlier versions of the macrobiotic diet that involved eating only brown rice and water has been linked to severe nutritional deficiencies and even death.<ref name="CA 1993"/> Strict macrobiotic diets that include no animal products may result in nutritional deficiencies unless they are carefully planned. The danger may be worse for people with cancer, who may have to contend with unwanted weight loss and often have increased nutritional and caloric requirements. Relying on this type of treatment alone and avoiding or delaying conventional medical care for cancer may have serious health consequences.<ref name=ACS/>

Cases of vitamin B12 and iron-deficiency anemias have been reported as a result of the diet.<ref name="Barrett 1993"/><ref>Template:Cite journal</ref>

ChildrenEdit

Children may also be particularly prone to nutritional deficiencies resulting from a macrobiotic diet.<ref name=ACS /> A macrobiotic diet does not contain the nutrients needed by growing children.<ref>Template:Cite book</ref>

PregnancyEdit

Macrobiotic diets have not been tested in women who are pregnant or breast-feeding, and the most extreme versions may not include enough of certain nutrients for normal fetal growth.<ref name=ACS/>
