'''Raw foodism''', also known as '''rawism''' or a '''raw food diet''', is the [[diet (nutrition)|dietary practice]] of eating only or mostly food that is [[cooking|uncooked]] and [[processed food|unprocessed]]. Depending on the philosophy, or type of lifestyle and results desired, raw food diets may include a selection of fruits, vegetables, nuts, seeds, eggs, fish, meat, and dairy products. The diet may also include simply processed foods, such as various types of [[sprouting|sprouted seeds]], cheese, and [[fermented]] foods such as [[yogurt]]s, [[kefir]], [[kombucha]], or [[sauerkraut]], but generally not foods that have been [[Pasteurization|pasteurized]], [[Homogenization (chemistry)|homogenized]], or produced with the use of synthetic [[pesticides]], [[fertilizer]]s, [[solvent]]s, and [[food additives]]. |

A raw vegan diet consists of unprocessed, raw plant foods that have not been heated above {{convert|40-49|°C|°F|lk=on}}. Raw vegans such as Brian Clement, [[Gabriel Cousens]], Thierry Browers a.k.a. "Superlight", and Douglas Graham<ref>{{cite web|url=http://foodnsport.com/blog/articles/the-challenges-of-going-on-a-raw-food-diet.html |title=The Challenges of Going on a Raw Food Diet |publisher=FoodnSport.com |accessdate=2011-03-31| first=Douglas | last=Graham}}</ref> believe that foods cooked above this temperature have lost much of their nutritional value and are less healthful or even harmful to the body.{{Lopsided|date=December 2015}} Advocates argue that raw or living foods have natural enzymes, which are critical in building proteins and rebuilding the body, and that heating these foods destroys the natural enzymes and can leave toxic materials behind. However, critics point out that enzymes, as with other proteins consumed in the diet, are denatured and eventually lysed by the digestive process, rendering them non-functional. Typical foods included in raw food diets are fruits, vegetables, nuts, seeds, and sprouted grains and legumes. |
|||
Among raw vegans there are some subgroups such as [[fruitarianism|fruitarians]], juicearians, or sproutarians. Fruitarians eat primarily or exclusively fruits, berries, seeds, and nuts. Juicearians process their raw plant foods into juice. Sproutarians adhere to a diet consisting mainly of [[edible sprouts|sprouted seeds]]. |

===Raw vegetarianism=== |

Vegetarianism is a diet that excludes meat (including game and byproducts like gelatin), fish (including shellfish and other sea animals) and poultry, but allows dairy and/or eggs. Common foods include fruit, vegetables, sprouts, nuts, seeds, grains, legumes, dairy, eggs and honey. There are several variants of this diet.<ref>{{cite web|url=http://www.askoxford.com/concise_oed/vegetarian?view=uk |title=AskOxford: vegetarian |publisher=Askoxford.com |accessdate=2008-11-07}}</ref> |

In the 1830s, Presbyterian minister [[Sylvester Graham]] promoted dietary principles similar to the raw food diet as a proposed cure for the then-current [[cholera]] epidemic threatening to strike the United States. Graham, most noted for the famous [[graham cracker]], claimed chronic disease in general and cholera in particular could be prevented by drinking pure water and eating simple fresh food not complicated or compounded by culinary practices.<ref>Graham, Sylvester. Lectures on the science of human life. 1849.</ref> Graham saw such simple fare as a method to cure lust; for Graham, an unhealthy diet stimulated excessive sexual desire which irritated the body and caused disease. |

Raw food as a dietary health treatment was first developed in Switzerland by medical doctor [[Maximilian Bircher-Benner]], inventor of [[muesli]]. After recovering from [[jaundice]] while eating raw apples, he conducted experiments into the effects on human health of raw vegetables. In November 1897, he opened a sanatorium in Zurich called "Vital Force," named after a "key term from the German lifestyle reform movement, which states that people should pattern their lives after the logic determined by nature".<ref>{{cite web|url= http://www.zurich.com/developmentcenter/aboutzurichdevelopmentcenter/locationhistory/biographybircher.htm |title=Biography of Max Bircher-Benner|accessdate=2011-07-11}}</ref>{{lopsided|date=December 2015}}{{unreliable source|date=December 2015}} |

Early documentation of raw food dieting has been associated with [[hermit]]s and [[monk]]s practising [[asceticism]]. For example, [[John of Egypt]], a hermit from the [[Nitrian Desert]] in the 4th Century, reportedly lived on a diet of dried fruit and vegetables for fifty years; he never ate anything cooked.<ref>Bangley, Bernard.

==Beliefs== |
|||
Beliefs held by raw foodists may include: |
|||
* That heating food above 104-118 °Fahrenheit (40-49 °C) starts to degrade and destroy the [[Enzymes#Biological function|enzymes]] in raw food that aid digestion.<ref>{{cite web |url=http://www.holisticjunction.com/articles/8019.html |title="Digestive Enzymes do More than just Aid Digestion", an article at Holistic Junction |publisher=Holisticjunction.com |date=2007-08-24 |accessdate=2010-05-12}} {{dead link|date=May 2015}}</ref><ref>{{cite web |url=http://www.lef.org/magazine/mag99/apr99-cover.html |title=Life Extension Magazine, April 1999, ''Digestive Enzymes: The Missing Link'' |publisher=Lef.org |date=1999-04-01 |accessdate=2010-05-12}} {{dead link|date=February 2015}}</ref> A few raw foodists such as Douglas Graham dispute the importance of enzymes in foods.<ref>{{cite web |url=http://foodnsport.com/blog/articles/enzymes-are-they-for-real.html |title=Enzymes: Are They for Real? |publisher=FoodnSport.com | first=Douglas | last=Graham}}</ref> |
|||
* That raw foods include [[bacteria]] and other [[micro-organisms]] that affect the [[immune system]] and [[digestion]] by populating the [[digestive tract]] with beneficial [[gut flora]]. In addition, many raw-foodists, particularly primal-dieters, are believers in the [[hygiene hypothesis]], a concept that promotes the health benefits of exposure to natural, symbiotic bacteria like those found in unpasteurized fermented foods. |
|||
* That raw foods have higher [[nutrient]] values than foods that have been cooked.<ref name="Encyclopedia.com">{{cite web|url=http://www.encyclopedia.com/doc/1O39-cookinglossofnutrients.html |title=cooking, loss of nutrients - Health Information About cooking, loss of nutrients | Encyclopedia.com: Dictionary Of Food and Nutrition |publisher=Encyclopedia.com |accessdate=2008-11-07}}</ref><ref name="Nutritiondata.com">{{cite web|url=http://www.nutritiondata.com/topics/processing |title=Nutritional Effects of Food Processing – NutritionData.com |publisher=Nutritiondata.com |accessdate=2008-11-07}}</ref><ref name="jn.nutrition.org">{{Cite journal|first1=Agnes Fay |last1=Morgan |first2=Grace E. |last2=Kern |date=April 1934 |title=The Effect of Heat Upon the Biological Value of Meat Protein |url=http://jn.nutrition.org/cgi/reprint/7/4/367.pdf |journal=The Journal of Nutrition |volume=7 |issue=4 |pages=367–79}}</ref> |
|||
* That [[processed food]] and [[convenience food]] often contain ''excitotoxins'' (such as [[flavour enhancer|flavor enhancers]]) that can cause [[excitotoxicity]]{{Citation needed|date=December 2013}}. Foods with added chemicals, [[Food preservatives|preservatives]], [[Food additive|additives]], [[Food coloring|colouring agents/dyes]] of any kind are frowned upon by most raw-foodists. |
|||
* That raw foods are the ideal food for human consumption, and the basis of a raw food lifestyle. Irritants or stimulants like coffee, alcohol, and tobacco are not recommended. Also heated fats and proteins like fried oils and roasted nuts are to be avoided, as they are deemed by many raw foodists to be carcinogenic. |

* That wild foods followed by organic whole foods are more nutritious than conventionally domesticated foods or [[food industry|industrially produced foods]].<ref>{{cite web|url=http://www.medicalnewstoday.com/articles/86972.php |title=Organic Food Is More Nutritious Say EU Researchers |publisher=Medicalnewstoday.com |accessdate=2010-05-12}}</ref> |

Raw foodists believe that this property found in [[Alkalinity|alkaline]] living foods or raw food, which neutralizes free radicals, makes [[green smoothie]]s a powerful antioxidant drink. |

Contemporary raw food diets were first developed in Switzerland by [[Maximilian Bircher-Benner]] (1867–1939), who was influenced as a young man by the German ''[[Lebensreform]]'' movement, which saw civilization as corrupt and sought to go "back to nature"; it embraced [[holistic medicine]], [[nudism]], [[free love]], regular exercise and other outdoors activity, and foods that it judged were more "natural".<ref name="fitz">{{cite book |author=Fitzgerald |first=Matt |url=https://archive.org/details/dietcultssurpris0000fitz |title=Diet Cults: The Surprising Fallacy at the Core of Nutrition Fads and a Guide to Healthy Eating for the Rest of US |publisher=Pegasus Books |year=2014 |isbn=978-1-60598-560-2 |url-access=registration}}</ref>{{rp|41–43}} Bircher-Benner eventually adopted a [[Vegetarianism|vegetarian]] diet, but took that further and decided that raw food was what humans were really meant to eat; he was influenced by [[Charles Darwin]]'s ideas that humans were just another kind of animal and Bircher-Benner noted that other animals do not cook their food.<ref name="fitz" />{{rp|41–43}} In 1904 he opened a sanatorium in the mountains outside of Zurich called "Lebendinge Kraft" or "Vital Force", a technical term in the Lebensreform movement that referred especially to sunlight; he and others believed that this [[energy (esotericism)|energy]] was more "concentrated" in plants than in meat, and was diminished by cooking.<ref name="fitz" />{{rp|41–43}} Patients in the clinic were fed raw foods, including [[muesli]], which was created there.<ref name="fitz" />{{rp|41–43}} These ideas were influential to [[Ann Wigmore]], a notable raw food advocate, but were dismissed by scientists and the medical profession as quackery.<ref name="fitz" />{{rp|41–43}} |

One of the earliest books to advocate raw foodism was [[Eugene Christian]]'s ''Uncooked Foods and How to Use Them'', 1904.<ref name="Berry 2007">Berry, Rynn. (2007). "Raw Foodism". In Andrew F. Smith. ''The Oxford Companion to American Food and Drink''. [[Oxford University Press]]. pp. 493–494. {{ISBN|978-0-19-530796-2}}</ref> Other proponents from the early part of the twentieth century include Californian fruit grower [[Otto Carque]] (author of ''The Foundation of All Reform'', 1904), [[George Julius Drews]] (author of ''Unfired Food and Trophotherapy'', 1912), [[Bernarr Macfadden]] and [[Herbert Shelton]]. Drews influenced [[John and Vera Richter]] to open America's first raw food restaurant "The Eutropheon" in 1917.<ref name="Berry 2007"/> |
|||
Many foods in raw food diets are simple to prepare, such as fruits, salads, meat, and dairy.{{cn|date=December 2015}} Other foods can require considerable advanced planning to prepare for eating. Rice and some other grains, for example, require [[sprouting]] or overnight soaking to become digestible. Many raw foodists believe it is best to soak nuts and seeds before eating them, to activate their [[enzymes]], and deactivate enzyme inhibitors.<ref>Calabrese, Karyn (2011). "Soak Your Nuts: Cleansing With Karyn: Detox Secrets for Inner Healing and Outer Beauty." Healthy Living Publications</ref> The amount of soak time varies for all nuts and seeds. |
|||
Shelton was arrested, jailed, and fined numerous times for practising medicine without a license during his career as an advocate of rawism and other alternative health and diet philosophies. Shelton's legacy, as popularized by books like ''[[Fit for Life]]'' by Harvey and [[Marilyn Diamond]], has been deemed "pseudonutrition" by the National Council Against Health Fraud.<ref>{{cite web|last=Jarvis, PhD|first=William T.|title=Fasting|url=http://www.ncahf.org/articles/e-i/fasting.html |publisher=National Council Against Health Fraud|access-date=8 April 2014}}</ref> |
|||
According to some cookbook authors, preparation of ''gourmet'' raw food recipes usually calls for a [[blender (device)|blender]], [[food processor]], [[juicer]], and [[Food dehydrator|dehydrator]].<ref>{{cite web|url=http://www.allmyrecipes.com/diets/raw_food.php |title=About the Raw Food (Living Foods) Diet |publisher=Allmyrecipes.com |accessdate=2008-11-07}}</ref> Depending on the recipe, some food (such as crackers, breads and cookies) may need to be dehydrated. These processes, which produce foods with the taste and texture of cooked food, are lengthy. |

In the 1970s, [[Norman W. Walker]] (inventor of the Norwalk Juicing Press) popularized raw food dieting.<ref>Coull, Lauren. (2015). "Raw Food". In Andrew F. Smith.

[[Freezing]] food is acceptable, even though freezing lowers enzyme activity.

In the 21st century, raw food diets (particularly those focused on [[raw milk]], raw eggs and raw meat) have been popularized and politicized as part of a broader "[[right-wing]] bodybuilder" movement centered around [[hypermasculinity]], physical fitness, fascination with ancient civilizations and opposition to [[feminism]] and mainstream modern culture.<ref name="rwbb">{{cite web|url=https://www.dazeddigital.com/beauty/body/article/55602/1/unpacking-the-weird-alt-right-propaganda-behind-the-raw-meat-movement|title=Unpacking the weird alt-right propaganda behind the raw meat movement|website=[[Dazed Digital]]|date=14 March 2022}}</ref> |

A study surveying people practicing raw vegan diets of varying intensities found that 30% of the women under age 45 had partial to complete [[amenorrhoea]] and that "subjects eating high amounts of raw food (> 90%) were affected more frequently than moderate raw food dieters". The study concluded that since many raw food dieters were underweight and exhibited amenorrhoea "a very strict raw vegan diet cannot be recommended on a long-term basis".<ref>{{cite web|url=http://content.karger.com/ProdukteDB/produkte.asp?Aktion=ShowAbstract&ArtikelNr=12770&Ausgabe=224613&ProduktNr=223977 |title=Consequences of a Long-Term Raw Food Diet on Body Weight and Menstruation: Results of a Questionnaire Survey |publisher=Content.karger.com |accessdate=2008-11-07}}</ref> |

One review stated that "Many raw foods are toxic and only become safe after they have been cooked. Some raw foods contain [[Antinutrient|substances that affect the absorption of nutrients]], interfere with digestive enzymes or damage the walls of the intestine.

Cooking also creates certain heat-created toxic compounds, [[Advanced glycation end-product|advanced glycation end products]], otherwise known as AGEs. This reaction occurs both within the body and external to the body.

Raw foodism, also known as rawism or a raw food diet, is the dietary practice of eating only or mostly food that is uncooked and unprocessed. Depending on the philosophy, or type of lifestyle and results desired, raw food diets may include a selection of fruits, vegetables, nuts, seeds, eggs, fish, meat, and dairy products. The diet may also include simply processed foods, such as various types of sprouted seeds, cheese, and fermented foods such as yogurts, kefir, kombucha, or sauerkraut, but generally not foods that have been pasteurized, homogenized, or produced with the use of synthetic pesticides, fertilizers, solvents, and food additives.
The British Dietetic Association has described raw foodism as a fad diet.[1] Raw food diets, specifically raw veganism, may diminish intake of essential minerals and nutrients, such as vitamin B12.[1][2][3] Claims made by raw food proponents are pseudoscientific.[4]: 44
Varieties
[edit]Raw food diets are diets composed entirely or mostly of food that is uncooked or that is cooked at low temperatures.[2][3][5]
Raw animal food diets
[edit]Raw animal food diets include any animal that can be eaten raw, such as uncooked, unprocessed raw muscle-meats/organ-meats/eggs, raw dairy, and aged, raw animal foods such as century eggs, fermented meat/fish/shellfish/kefir, as well as vegetables, fruits, nuts, and sprouts, but in general not raw grains, raw beans, and raw soy. Raw foods included on such diets have not been heated above 40 °C (104 °F).[3][6] "Raw Animal Foodists" believe that foods cooked above this temperature have lost much of their nutritional value and are harmful to the body. Smoked meats are frowned upon by many Raw-Omnivores.[7] Some make a distinction between hot-smoked and cold-smoked.
Diet examples
[edit]- The "People's Primal Potluck",[8][9] anopsology (otherwise known as "instinctive eating"), and the "Raw Paleolithic Diet"[10][11] (otherwise known as the "raw meat diet").[12]
- The "primal diet" consists of fatty meats, organ meats, dairy, honey, minimal fruit and vegetable juices, and coconut products, all raw.[13][14]
- The "raw Paleolithic diet",[11][15] is a raw version of the (cooked) Palaeolithic diet, incorporating large amounts of raw animal foods such as meats/organ-meats, seafood, eggs, and some raw plant-foods, but usually avoiding non-Paleo foods such as raw dairy, grains, and legumes.[11][12]
The founder of the Primal Diet is Aajonus Vonderplanitz, a resident of Malibu, California. It has been estimated by Aajonus Vonderplanitz that there are 20,000 followers of his raw-meat-heavy Primal Diet in North America, alone.[13]
- Aboriginal diets consisted of large quantities of raw meats, organ meats, and berries, including the traditional diet of the Nenets tribe of Siberia,[16] and the Inuit.[17][18][19]
- Pemmican is the traditional North American travel food, prepared from dried meat, fat, and berries.[20]

Raw veganism
[edit]Raw veganism has rarely been practised in history,[21] but it became a fad in the 21st century.[22] A raw vegan diet consists of unprocessed, raw plant foods that have not been heated above 40–49 °C (104–120 °F). Typical foods included in raw food diets are fruits, vegetables, nuts, seeds, and sprouted grains and legumes.
Among raw vegans are subgroups, such as "fruitarians", "juicearians", or "sproutarians". Fruitarians eat primarily or exclusively fruits, berries, seeds, and nuts. Juicearians process their raw plant foods into juice.[23]
The British Dietetic Association named the raw vegan diet one of the "top 5 worst celeb diets to avoid in 2018", raising a concern that it could compromise long-term health.[24]
History
[edit]Early documentation of raw food dieting has been associated with hermits and monks practising asceticism. For example, John of Egypt, a hermit from the Nitrian Desert in the 4th Century, reportedly lived on a diet of dried fruit and vegetables for fifty years; he never ate anything cooked.[25] Documented evidence of a commitment to raw food was by the Ethiopian monk Qozmos, who in the late 1300s CE committed to the ascetic discipline of eating only uncooked food.[26][27] This posed a problem for his Ethiopian Orthodox Tewahedo Church monastery because he refused to eat the bread of the Eucharist, which is cooked. As a result, he fled the church and went to live with the Jewish community of the Beta Israel.[26][27]
Contemporary raw food diets were first developed in Switzerland by Maximilian Bircher-Benner (1867–1939), who was influenced as a young man by the German Lebensreform movement, which saw civilization as corrupt and sought to go "back to nature"; it embraced holistic medicine, nudism, free love, regular exercise and other outdoors activity, and foods that it judged were more "natural".[4]: 41–43 Bircher-Benner eventually adopted a vegetarian diet, but took that further and decided that raw food was what humans were really meant to eat; he was influenced by Charles Darwin's ideas that humans were just another kind of animal and Bircher-Benner noted that other animals do not cook their food.[4]: 41–43 In 1904 he opened a sanatorium in the mountains outside of Zurich called "Lebendinge Kraft" or "Vital Force", a technical term in the Lebensreform movement that referred especially to sunlight; he and others believed that this energy was more "concentrated" in plants than in meat, and was diminished by cooking.[4]: 41–43 Patients in the clinic were fed raw foods, including muesli, which was created there.[4]: 41–43 These ideas were influential to Ann Wigmore, a notable raw food advocate, but were dismissed by scientists and the medical profession as quackery.[4]: 41–43
One of the earliest books to advocate raw foodism was Eugene Christian's Uncooked Foods and How to Use Them, 1904.[28] Other proponents from the early part of the twentieth century include Californian fruit grower Otto Carque (author of The Foundation of All Reform, 1904), George Julius Drews (author of Unfired Food and Trophotherapy, 1912), Bernarr Macfadden and Herbert Shelton. Drews influenced John and Vera Richter to open America's first raw food restaurant "The Eutropheon" in 1917.[28]
Shelton was arrested, jailed, and fined numerous times for practising medicine without a license during his career as an advocate of rawism and other alternative health and diet philosophies. Shelton's legacy, as popularized by books like Fit for Life by Harvey and Marilyn Diamond, has been deemed "pseudonutrition" by the National Council Against Health Fraud.[29]
In the 1970s, Norman W. Walker (inventor of the Norwalk Juicing Press) popularized raw food dieting.[30] Leslie Kenton's book Raw Energy – Eat Your Way to Radiant Health, published in 1984, added popularity to foods such as sprouts, seeds, and fresh vegetable juices.[31] The book advocates a diet of 75% raw food, which it claims will prevent degenerative diseases, slow the effects of aging, provide enhanced energy, and boost emotional balance; it cites examples such as the sprouted-seed-enriched diets of the long-lived Hunza people and Gerson therapy, an unhealthy, dangerous and potentially very harmful[32][33] raw juice-based diet and detoxification regime claimed to treat cancer.[32]
In the 21st century, raw food diets (particularly those focused on raw milk, raw eggs and raw meat) have been popularized and politicized as part of a broader "right-wing bodybuilder" movement centered around hypermasculinity, physical fitness, fascination with ancient civilizations and opposition to feminism and mainstream modern culture.[34]
Claims
[edit]Claims held by raw food proponents include:
- That heating food above 104–118 °F (40–48 °C) degrades enzymes in raw food that aid digestion. In fact, enzymes in food play no significant role in the digestive process, prior to being digested themselves.[3]
- That raw foods have higher nutrient values than foods that have been cooked.[4]: 44 In fact, cooking has widely variable results on nutritional content, depending on the plant source and cooking method, and may actually increase availability of fat-based nutrients, such as vitamin E and beta-carotene.[3][35][36]
- That foods cooked at high temperatures, especially meat, may contain harmful toxins, including trans fatty acids produced by heating oil, acrylamide produced by frying, advanced glycation end products (AGEs), and polycyclic aromatic hydrocarbons.[37] Not all cooked food contains harmful chemicals, and a diet containing a mix of cooked and raw food is normal.[37][38] According to the American Cancer Society, it is not clear as of 2019[update] whether acrylamide consumption affects the risk of cancer.[39] Public health authorities recommend reducing consumption of overly-cooked starchy foods or meats.[37][39][40]
Health effects
[edit]A raw food diet is likely to impair the development of children and infants.[41] Care is required in planning a raw vegan diet, especially for children,[42] as there may not be enough vitamin B12, vitamin D, and calories for a growing child on a totally raw vegan diet.[43]
Food poisoning is a health risk for all people eating raw foods, and increased demand for raw foods is associated with greater incidence of foodborne illness,[44] especially for raw meat, fish, and shellfish.[45][46] Outbreaks of gastroenteritis among consumers of raw and undercooked animal products (including smoked, pickled or dried animal products[45]) are well-documented, and include raw meat,[45][47][48] raw organ meat,[47] raw fish (whether ocean-going or freshwater),[45][46][48] shellfish,[49] raw milk and products made from raw milk,[50][51][52] and raw eggs.[53]
One review stated that "Many raw foods are toxic and only become safe after they have been cooked. Some raw foods contain substances that affect the absorption of nutrients, interfere with digestive enzymes or damage the walls of the intestine. Raw meat can be contaminated with bacteria which would be destroyed by cooking; raw fish can contain substances that interfere with vitamin B1 (anti-thiaminases)".[54]
