diet excludes all animal products, and can be accompanied by abstention from the use of animal-derived products, such as leather shoes. Maintenance of a vegetarian diet can be challenging. While avoidance of animal products may support health and ethical concerns, dietary supplements may be needed to prevent nutritional deficiency if all such products are shunned, particularly for vitamin B12. Packaged and processed foods may contain minor quantities of animal ingredients. While some vegetarians scrutinize product labels for such ingredients, others do not object to consuming them, or are unaware of their presence.


Origin

The first written use of the term "vegetarian" originated in the early 19th century, when authors referred to a ''vegetable regimen'' diet. Historically, 'vegetable' could be used to refer to any type of edible
vegetation Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic charact ...

A History of Vegetarianism'', London 1993, p. 252. The ''OED'' writes that the word came into general use after the formation of the Vegetarian Society at Ramsgate in 1847, though it offers two examples of usage from 1839 and 1842: * 1839: "If I had had to be my own cook, I should inevitably become a vegetarian." (F. A. Kemble, ''Jrnl. Residence on Georgian Plantation'' (1863) 251) * 1842: "To tell a healthy vegetarian that his diet is very uncongenial with the wants of his nature." (''Healthian'', Apr. 34) The 1839 occurrence remains under discussion; the Oxford English Dictionary's 1839 source is in fact an 1863 publication: Fanny Kemble, ''Journal of a Residence on a Georgian Plantation 1838–1839''. The original manuscript has not been located. although it may have appeared in print before 1847. The earliest occurrences of the term seem to be related to Alcott House—a school on the north side of Ham Common, London—which was opened in July 1838 by James Pierrepont Greaves. From 1841, it was known as ''A Concordium, or Industry Harmony College'', from which time the institution began to publish its own pamphlet entitled ''The Healthian'', which provides some of the earliest appearances of the term "vegetarian".

Varieties

There are a number of vegetarian diets that exclude or include various foods: * Fruitarianism permits only fruit, nuts, seeds, and other plant matter that can be gathered without harming the plant. * Macrobiotic diets consist mostly of whole grains and beans. * Lacto vegetarianism includes dairy products but not eggs. * Ovo vegetarianism includes eggs but not dairy products. * Ovo-lacto vegetarianism (or lacto-ovo vegetarianism) includes animal products such as eggs, milk, and honey. * Sattvic diet (also known as yogic diet), a plant-based diet which may also include dairy and honey, but excludes eggs,

Semi-vegetarian diets include: * Pescetarianism, which includes fish and possibly other forms of seafood. * Pollotarianism, which includes chicken and possibly other poultry. Semi-vegetarianism is contested by vegetarian groups, such as the Vegetarian Society, which states that vegetarianism excludes all animal flesh.


Health research

In western countries, the most common motive for people practicing vegetarianism is health consciousness. The American Dietetic Association has stated that at all stages of life, a properly planned vegetarian diet can be "healthful, nutritionally adequate, and may be beneficial in the prevention and treatment of certain diseases."

Iron

Vegetarian diets typically contain similar levels of iron to non-vegetarian diets, but this has lower bioavailability than iron from meat sources, and its absorption can sometimes be inhibited by other dietary constituents.

. The related vegan diets can often be higher in iron than vegetarian diets, because dairy products are low in iron. Iron stores often tend to be lower in vegetarians than non-vegetarians, and a few small studies report very high rates of iron deficiency (up to 40%, and 58% of the respective vegetarian or vegan groups). However, the American Dietetic Association states that iron deficiency is no more common in vegetarians than non-vegetarians (adult males are rarely iron deficient); iron deficiency anaemia is rare no matter the diet.

intake in vegetarians and vegans can be similar to non-vegetarians, as long as the diet is properly planned. Lacto-ovo vegetarians that include dairy products can still obtain calcium from dairy sources like milk, yogurt, and cheese. Non-dairy milks that are fortified with calcium, such as soymilk and almond milk can also contribute a significant amount of calcium in the diet. Broccoli, bok choy, and kale have also been found to have calcium that is well absorbed in the body. Though the calcium content per serving is lower in these vegetables than a glass of milk, the absorption of the calcium into the body is higher. Other foods that contain calcium include calcium-set tofu, blackstrap molasses, turnip greens, mustard greens, soybeans, tempeh, almonds, okra, dried figs, and

value is not a sufficient cause. Another common view is that humans are morally conscious of their behavior in a way other animals are not, and therefore subject to higher standards. Jeff McMahan proposes that denying the right to life and humane treatment to animals with equal or greater cognitive abilities than mentally disabled humans is an arbitrary and discriminatory practice based on habit instead of logic. Opponents of ethical vegetarianism argue that animals are not moral equals to humans and so consider the comparison of eating livestock with killing people to be fallacious. This view does not excuse cruelty, but maintains that animals do not possess the rights a human has.

Christianity

Various groups within Christianity have practiced specific dietary restrictions for various reasons.

indicate their belief that – as Christ is the Passover sacrifice and eating the Passover lamb is no longer required – a vegetarian diet may (or should) be observed. However, orthodox Christianity does not accept their teaching as authentic. Indeed, their specific injunction to strict vegetarianism was cited as one of the Ebionites' "errors". At a much later time, the Bible Christian Church founded by Reverend William Cowherd in 1809 followed a vegetarian diet. Cowherd was one of the philosophical forerunners of the Vegetarian Society.; Gregory, James (2007) ''Of Victorians and Vegetarians''. London: I. B. Tauris pp. 30–35. Cowherd encouraged members to abstain from eating of meat as a form of temperance. Seventh-day Adventists are encouraged to engage in healthy eating practices, and ovo-lacto-vegetarian diets are recommended by the General Conference of Seventh-day Adventists Nutrition Council (GCNC). They have also sponsored and participated in many scientific studies exploring the impact of dietary decisions upon health outcomes. The GCNC has in addition adapted the

believe that all living organisms, including microorganisms, are living and have a soul, and have one or more senses out of five senses. They go to great lengths to minimise any harm to any living organism. Most Jains are lacto-vegetarians, but more devout Jains do not eat root vegetables, because they believe that root vegetables contain many more microorganisms as compared to other vegetables, and that, by eating them, violence against these microorganisms is inevitable. They therefore prefer eating beans and fruits, whose cultivation involves killing fewer microorganisms. No products obtained from already-dead animals are allowed because of potential violence against decomposing microorganisms. Some particularly dedicated individuals are fruitarians. Honey is forbidden, being the regurgitation of nectar by bees and potentially containing eggs, excreta and dead bees. Many Jains do not consume plant parts that grow underground such as roots and bulbs, because the plants themselves and tiny animals may be killed when the plants are pulled up.


Judaism

While classical Jewish law neither requires nor prohibits the consumption of meat, Jewish vegetarians often cite Jewish principles regarding

Rabbis may advocate vegetarianism or veganism primarily because of concerns about animal welfare, especially in light of the traditional prohibition on causing unnecessary "pain to living creatures" ( tza'ar ba'alei hayyim).

permission to eat meat is a temporary leniency for those who are not ready yet to accept the vegetarian diet. The book of Daniel starts in it
first chapter
with the benefits of vegetarianism. Due to its size, its late time of origin and its revealing content, the book is of particular importance for the time of the following exile, which lasts now for 2000 years and technically still goes on until the Temple in Jerusalem is rebuilt. A diet described as "pulse and water" is presented along benefits such as accordance with the biblical dietary laws, health, beauty, wisdom and visions. Vegetarianism can be seen as a safeguard around the dietary laws or the beautification of them. Jewish vegetarianism and veganism have become especially popular among Israeli Jews. In 2016, Israel was described as "the most vegan country on Earth", as five percent of its population eschewed all animal products. Interest in veganism has grown among both non-Orthodox and Orthodox Jews in Israel.

and follow the dietary regulations with varying degrees of strictness. The most orthodox eat only " Ital" or natural foods, in which the matching of herbs or spices with vegetables is the result of long tradition originating from the African ancestry and cultural heritage of Rastafari. "Ital", which is derived from the word vital, means essential to human existence. Ital cooking in its strictest form prohibits the use of salt, meat (especially pork), preservatives, colorings, flavorings and anything artificial. Most Rastafari are vegetarian.

The Sikh langar, or free temple meal, is largely lacto-vegetarian, though this is understood to be a result of efforts to present a meal that is respectful of the diets of any person who would wish to dine, rather than out of dogma.


Environment and diet

Environmental vegetarianism is based on the concern that the production of meat and animal products for mass consumption, especially through
factory farming Intensive animal farming or industrial livestock production, also known by its opponents as factory farming and macro-farms, is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production, whil ...

. The initiative concluded that "the livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global." In addition, animal agriculture is a large source of greenhouse gases. According to a 2006 report it is responsible for 18% of the world's greenhouse gas emissions as estimated in 100-year CO2 equivalents. Livestock sources (including enteric fermentation and manure) account for about 3.1 percent of US anthropogenic GHG emissions expressed as carbon dioxide equivalents. This EPA estimate is based on methodologies agreed to by the Conference of Parties of the UNFCCC, with 100-year global warming potentials from the IPCC Second Assessment Report used in estimating GHG emissions as carbon dioxide equivalents. Meat produced in a laboratory (called in vitro meat) may be more environmentally sustainable than regularly produced meat. Reactions of vegetarians vary. Rearing a relatively small number of grazing animals can be beneficial, as the Food Climate Research Network at Surrey University reports: "A little bit of livestock production is probably a good thing for the environment".

, Belgium, was reported to be "the first ityin the world to go vegetarian at least once a week" for environmental reasons, when local authorities decided to implement a "weekly meatless day". Civil servants would eat vegetarian meals one day per week, in recognition of the United Nations' report. Posters were put up by local authorities to encourage the population to take part on vegetarian days, and "veggie street maps" were printed to highlight vegetarian restaurants. In September 2009, schools in Ghent are due to have a weekly ''veggiedag'' ("vegetarian day") too. Public opinion and acceptance of meat-free food is expected to be more successful if its descriptive words focus less on the health aspects and more on the flavor.


Labor conditions and diet

Some groups, such as PETA, promote vegetarianism as a way to offset poor treatment and working conditions of workers in the contemporary meat industry. These groups cite studies showing the psychological damage caused by working in the meat industry, especially in factory and industrialised settings, and argue that the meat industry violates its labourers' human rights by assigning difficult and distressing tasks without adequate counselling, training and debriefing.Positive Safety Culture. The key to a safer meat industry
, A literature review July 2000, safework.sa.gov.au
However, the working conditions of agricultural workers as a whole, particularly non-permanent workers, remain poor and well below conditions prevailing in other economic sectors. Accidents, including pesticide poisoning, among farmers and plantation workers contribute to increased health risks, including increased mortality. According to the

Economics and diet

Similar to environmental vegetarianism is the concept of economic vegetarianism. An economic vegetarian is someone who practices vegetarianism from either the philosophical viewpoint concerning issues such as public health and curbing world starvation, the belief that the consumption of meat is economically unsound, part of a conscious

strategy or just out of necessity. According to the Worldwatch Institute, "Massive reductions in meat consumption in industrial nations will ease their health care burden while improving public health; declining livestock herds will take pressure off rangelands and grainlands, allowing the agricultural resource base to rejuvenate. As populations grow, lowering meat consumption worldwide will allow more efficient use of declining per capita land and water resources, while at the same time making grain more affordable to the world's chronically hungry." According to estimates in 2016, adoption of vegetarianism would contribute substantially to global healthcare and environmental savings.


Demographics

Prejudice researcher Gordon Hodson argues that vegetarians and vegans frequently face discrimination where eating meat is held as a cultural norm.


Turnover

Research suggests that, at least in the United States, vegetarianism has a high turnover rate, with less than 20% of adopters persisting for more than a year. Research shows that lacking social support contributes to lapses. A 2019 analysis found that adhering to any kind of restricted diet (gluten-free, vegetarian, kosher, teetotal) was associated with feelings of loneliness and increased social isolation. Vegetarians or vegans who adopted their diet abruptly might be more likely to eventually abandon it when compared to individuals adopting their diet gradually with incremental changes.


Country-specific information

The rate of vegetarianism by country varies substantially from relatively low levels in countries such as the Netherlands (5%) to more considerable levels in India (20–40%). Estimates for the number of vegetarians per country can be subject to methodological difficulties, as respondents may identify as vegetarian even if they include some meat in their diet, and thus some researchers suggest the percentage of vegetarians may be significantly overestimated.

, while there are "increasing social sanctions against eating meat" Over time, societal attitudes of vegetarianism have changed, as have perceptions of vegetarianism in popular culture, leading to more "vegetarian sentiment." Even so, there are still existing "meat-based" food metaphors which infuse daily speech and those who are vegetarian and vegan are met with "acceptance, tolerance, or hostility" after they divulge they are vegetarian or vegan. Some writers, such as John L. Cunningham, editor of the Vegetarian Resource Group's newsletter, have argued for "more sympathetic vegetarian characters in the mass media".

's 1922 novel, '' Ulysees'' is said to have vegetarian themes. Scholar Peter Adkins argued that while Joyce was critical of the vegetarianism of George A.E. Russell, the novel engages with "questions of animal ethics through its portrayal of Ireland's cattle industry, animal slaughter and the cultural currency of meat," unlike some of his other novels. He also stated that the novel "historicizes and theorizes animal life and death," and that it demonstrates the ways that symbolism and materiality of meat are "co-opted within patriarchal political structures," putting it in the same space as theorists like Carol J. Adams, Donna J. Haraway, Laura Wright, and Cary Wolfe, and writers such as J. M. Coetzee. In 1997, S. Reneé Wheeler wrote in the ''Vegetarian Journal'', saying that "finding books with vegetarian themes" is important for helping children "feel legitimate in being vegetarian." In 2004, writer J. M. Coetzee argued that since the "mode of consciousness of nonhuman species is quite different from human consciousness," it is hard for writers to realize this for animals, with a "temptation to project upon them feelings and thoughts that may belong only to our own human mind and heart," and stated that reviewers have ignored the presence of animals in his books. He also stated that animals are present in his "fiction either not at all or in a merely subsidiary role" because they occupy "a subsidiary place in our lives" and argued that it is not "possible to write about the inner lives of animals in any complex way."

Some argued the book was more about mental illness than vegetarianism. Others compared it to fictional works by Margaret Atwood.


Television

Vegetarians, and vegetarian themes, have appeared in various TV shows, such as ''Buffy the Vampire Slayer'', ''True Blood'', ''The Simpsons'', ''King of the Hill'', and ''South Park''. Spock stands out. Said to be "television's first vegetarian," he and other Vulcans avoided eating meat due to a "philosophy of non-violence."" He is identified as vegetarian following an episode where he was "transported back to pre-civilised times" and ate meat. Richard Marranca, in an issue of the ''Vegetarian Journal'', said that for Spock, like Kwai Chang Caine in Kung Fu, "vegetarianism was something authentic and taken for granted; it was the right thing to do based on compassion and logic." In 1995, ''The Simpsons'' episode "Lisa the Vegetarian" aired. Before recording their lines for the episode, showrunner David Mirkin, who had recently stopped consuming meat, gave Linda and Paul McCartney "a container of his favorite turkey substitute," with both voicing characters in an episode which focused around vegetarianism. Critic Alan Siegel said that before the episode vegetarians had been portrayed as "rarely as anything but one-dimensional hippies" but that this episode was different as it was "told from the point of view of the person becoming a vegetarian." He said that the episode was one of the "first times on television that vegetarians saw an honest depiction of themselves" and of people's reaction to their dietary choices. The idea for the episode was originally proposed by David X. Cohen and the McCartneys agreed on the condition that Lisa remain a vegetarian, with both satisfied with how the episode turned out. In the episode, Lisa decides to stop eating meat after bonding with a lamb at a petting zoo. Her schoolmates and family members ridicule her for her beliefs, but with the help of Apu as well as Paul McCartney, Paul and Linda McCartney, she commits to vegetarianism. The staff promised that she would remain a vegetarian, resulting in one of the few permanent character changes made in the show.Groening, Matt (2005). Commentary for "Lisa the Vegetarian", in ''The Simpsons: The Complete Seventh Season'' [DVD]. 20th Century Fox. In an August 2020 interview, McCartney said that he and is wife were worried that Lisa "would be a vegetarian for a week, then Homer would persuade her to eat a hot dog," but were assured by the producers that she would remain that way, and he was delighted that they "kept their word." In September 1998, the ''King of the Hill'' episode "And They Call It Bobby Love" aired on FOX. In the episode, "Bobby Hill (King of the Hill), Bobby has a relationship with a vegetarian named Marie. She later dumps him after he eats a steak in front of her. In the March 2002 ''South Park'' episode "Fun with Veal", Stan Marsh becomes a vegetarian after he learns that veal is made of baby cows, with Cartman makes fun of. The episode ends with the boys, including Stan, getting grounded, but not before going out with their parents for burgers, meaning that Stan is no longer a vegetarian. In the DVD commentary, the creators said they wanted to balance their message of not eating baby animals, by at the same time not advocating people abstain from meat consumption altogether. Aang, in the animated series ''Avatar: The Last Airbender'' and ''The Legend of Korra'' was vegetarian. According to the show's creators, "Buddhism and Taoism have been huge inspirations behind the idea for ''Avatar''." As shown in "The King of Omashu" and "The Headband", a notable aspect of Aang's character is his vegetarian diet, which is consistent with Buddhism,

Additionally, Steven Universe (character), Steven Universe, the protagonist in the show ''Steven Universe'' and the limited epilogue series, ''Steven Universe Future'', is a vegetarian. In the episode "Snow Day" of ''Steven Universe Future'', Steven tells the Gems he lives with that he has been a vegetarian for a month, drinks protein shakes and mentions that he does "his own skincare routine."


Film

In the 1999 film, ''Notting Hill (film), Notting Hill'', Keziah, played by Emma Bernard is a vegetarian. In one scene, Keziah tells William "Will" Thacker (played by Hugh Grant), that she is a fruitarian. She says she believes that "fruits and vegetables have feeling," meaning she opposes cooking them, only eating things that have "actually fallen off a tree or bush" and that are dead already, leading to what some describe as a negative depiction. In the 2000 film, ''But I'm A Cheerleader'', before Megan, one of the film's protagonists, is sent to a conversion therapy camp, her parents and others claim she is a lesbian because she is a vegetarian. ''Legally Blonde'', a 2001 film, also featured a vegetarian. When Elle Wood introduces herself at Harvard Law School, she describes herself and her dog as "Gemini vegetarians." In the 2018 Hollywood blockbuster, ''Black Panther (film), Black Panther'', M’Baku (voiced by Winston Duke), the Jabari tribe leader who lives in the mountains of Wakanda, declares to a White CIA agent named Everett Ross (voiced by Martin Freeman), "if you say one more word, I’ll feed you to my children!" After Everett is shaken by these words, he jokes, saying he is kidding because all those in his tribe, including himself, are vegetarians. Some praised this scene for challenging a stereotype of Black culture and the perception of what vegetarians look like. Duke later said that some Black outlets cooked vegan meals for him, and said that the scene is "kind of teaching kids that eating vegetables is cool," which is something he is for. Vegetarian themes have also been noted in the ''Twilight'' Twilight (novel series), novel (2005-2008) and The Twilight Saga (film series), film franchise (2008-2012), ''The Road'' (2006) and ''The Year of the Flood'' (2009). In March 2020, scholar Nathan Poirer reviewed ''Thinking Veganism in Literature and Culture: Towards a Vegan Theory'', a book edited by Emelia Quinn and Benjamin Westwood, and he concluded that veganism could "infiltrate popular culture without being perceived as threatening," while noting others who contribute to the book examining vegan cinema that "challenges the normality of human supremacy by situating humans as potential prey," and stating that the essays outline ways veganism can be successful in popular culture. Other scholars noted vegetarian themes in the films ''The Fault in Our Stars (film), The Fault in Our Stars'', ''The Princess Diaries (film), The Princess Diaries'' series, and the 2009 film, ''Vegetarian (film), Vegetarian''.
