Herbivores, that is, animals adapted to eat primarily plants, are sometimes referred to as vegetarian animals.

A selection of produce typical of a vegetarian diet.

Vegetarianism is a dietary practice excluding all body parts of any animal and products derived from animals (e.g. lard, tallow, gelatin, cochineal) from one's diet. Many contemporary vegetarian diets include some honey as well as milk and other dairy products, and some include eggs.

Varieties of vegetarianism

Different practices of vegetarianism include:

• Strict vegetarians avoid the consumption of all animal products (e.g., eggs, milk and cheese, honey). Today, strict vegetarians are commonly called vegans, though some reserve this term for those who additionally avoid usage of all kinds of animal products (e.g., leather), not just food.

• Ovo-lacto vegetarians eschew the eating of all meat, yet allow the consumption of animal products such as eggs and milk. Ovo-lacto vegetarians who are such for ethical reasons may additionally refuse to eat cheese made with animal-based enzymes, or eggs produced by factory farms. The term "vegetarian" is most commonly intended to mean "ovo-lacto vegetarian", particularly as "vegan" has gained acceptance as the term for stricter practice.

• Lacto vegetarianism refers to the practice of eschewing all meat, yet allowing the consumption of milk and its derivatives, like cheese, butter or yogurt.

• Similarly, ovo-vegetarians eat eggs in addition to their otherwise strictly vegetarian regimen.

Religious dietary restrictions come in many forms and are sometimes compatible with the secular terminology; see below.

The following are not generally considered vegetarianism:

• Fructarians, more commonly called "fruitarians", eat only fruit, nuts, seeds and other plant matter that can be gathered without harming the plant. Thus a fructarian will eat beans, tomatoes, cucumbers, pumpkins and the like, but will refuse to eat potatoes or spinach. Technically, fructarianism is a kind of vegetarianism, but its much stricter definition is very rarely seen as being the same thing as vegetarianism. It is also hotly disputed whether it is possible to avoid malnutrition with a fructarian diet. Fructarianism is much rarer than vegetarianism or veganism.

• Some people choose to avoid certain types of meat for many of the same reasons that others choose vegetarianism: health, ethical beliefs, and so forth. For example, some people will not eat "red meat" (mammal meat – beef, lamb, pork, etc.) while still consuming poultry and seafood. This is not considered true vegetarianism, but has recently been referred to in the media as semi-vegetarianism (or see Pesco/Pollo vegetarianism for other current terms). Some non-vegetarians assume vegetarianism to be Pesco/Pollo vegetarianism.

• Others might regard the suffering of animals in factory farm conditions as their sole reason for avoiding meat or meat based foods. These people will eat meat, or meat products, from animals raised under humane conditions or hunted in the wild. Some of these people would refer to themselves as vegetarians.

Use of the term vegetarian to include the eating of some types of animals is misleading. Some consider these errors inconsequential and feel, perhaps for lack of a better word, that they can best define themselves as "vegetarian" despite eating some meat. The resulting erosion of the traditional terminology can be pernicious, however, as any traditional vegetarian who has been expected to eat a dish because it "only contains a little meat" (or "is just fish") can readily attest.

Before 1847, when the word "vegetarian" was officially set to refer to someone who refuses to consume flesh of any kind, vegetarians were often referred to as "Pythagoreans". The use of the word "vegetarian" was decided at the 1847 meeting of the first Vegetarian Society meeting in Ramsgate, England.

Country-specific information

• In the United States, vegetarianism is usually synonymous with ovo-lacto vegetarianism. However, vegetarians are sometimes wrongly assumed to be Pesco/Pollo vegetarians who will tolerate some meat. It is also possible to order a vegetarian meal and be served meat.
• In the UK, due to its sizeable Hindu minority, vegetarianism often refers to the Hindu practice described further below. Conveniently, there is fairly consistent food labelling in place, where all groceries that don't contain any meat or meat products would be labelled as "Suitable for vegetarians" (except where it's obvious; e.g. apples would not be labelled this way). Cheese is labelled as well, making it possible to distinguish between cheese that was made without using animal rennet and such that was made with the animal product.
• In Ireland, the same food labelling is also in place.
• In Germany, the confusion of vegetarianism with Pesco/Pollo vegetarianism is also common. There is no food labelling in place, and buying only vegetarian foods can involve having to read the fine printed ingredients list ("Zutaten") on many food products.

Motivations

Religion

A majority of the world's vegetarians follow the practice for religious reasons. Many religions, including Buddhism, Hinduism, Taoism and especially Jainism, teach that ideally life should always be valued and not willfully destroyed for unnecessary human gratification.

Abrahamic religions

Jews, Christians and Moslems are all left with the biblical ideal of the "Garden of Eden" diet, which from all appearances is strictly vegan (cf. Gen. 1:29, 9:2-4; Is. 11:6-9). However, only minorities within these populations actually practice and advocate such strict diets, since the same book of the Bible, Genesis, later gives permission to Noah's descendants to consume animal flesh, but not without great suffering simultaneously administered to all creatures: "The fear and dread of you will fall upon all the beasts of the earth and all the birds of the air, upon every creature that moves along the ground, and upon all the fish of the sea" (Gen. 9:2). Suffice to say, the Judeo-Christian God's permission for humankind to eat meat was not an unmixed or otherwise "unqualified" blessing. It was a concession, with penalties--not the least of which was, most probably, a dramatically decreased life expectancy (see Gen. 6:3). (Noah's great-grandfather, Methuselah, is famously reported as having lived an amazing 969 years, prior to the dawn of God-authorized human meat-eating.)

In the Bible, the Book of Genesis teaches that human beings were originally vegetarian, but that later, following the Deluge, God permitted people to eat meat as well. Many Judeo-Christian vegetarians interpret this to mean that God originally intended human beings to be vegetarians, and that people would do well to be vegetarians, even though meat-eating is permitted. Additionally, some Biblical prophecy suggests that in the Messianic age, there will be universal vegetarianism, even among normally carnivorous animals. (For example, Isaiah 11:7 says, "The cow will feed with the bear, their young will lie down together, and the lion will eat straw like the ox.")

Judaism

Rabbinical Judaism discourages ascetic practices in general. With respect to food, this teaching may be summarized by the Talmudic statement, "Man will have to account for everything he saw but did not eat." To Jewish vegetarians wishing to remain consistent with this teaching, vegetarianism is not a form of self-deprivation, because the vegetarian does not desire to eat meat and believes it is healthier not to eat meat. On the other hand, the Talmud discourages indulgence and states that it is preferable that one's diet consist mostly of non-meat products. There are several arguments from Judaism used by Jewish vegetarians. One is that, since Adam and Eve were not allowed to eat meat and that, according to some opinions, in the Messianic era, the whole world will be vegetarian, not eating meat is something that brings the world closer to that ideal. A second one is that the laws of shechita are meant to prevent the suffering of animals and today, with factory farming, even kosher slaughterhouses are considered by some authorities not to fulfil enough of the requirements to render the meat kosher. A third one is that the Sages only mandated eating an olive's bulk of meat during festivals, but even then, this was because in Talmudic times, meat was considered essential for one's diet (whereas a vegetarian will probably be of the opinion that current science has shown otherwise).

Christianity

In Christianity, Paul wrote in his Epistle to the Romans that although he himself ate meat, the choice to eat meat or abstain from meat should be a matter of personal conviction: "The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him." (Romans 14:3) Several Christian monastic groups have encouraged vegetarianism, including the Desert Fathers, Trappists, Benedictines, and Carthusians. Some Protestant groups, such as Seventh-day Adventists, take a literal interpretation of the Biblical prophecies of universal vegetarianism and encourage vegetarians as a preferred though not required lifestyle. In the nineteenth century, members of the Bible Christian sect established the first vegetarian groups in England and the United States.

Islam

Islam explicitly permits the eating of some kinds of meat. The hadith collection of al-Nasa'i recounts an episode wherein several of Mohammed's companions wish to practice various ascetic practices including sexual abstinence, vegetarianism, and extreme fasting, and Mohammed rebukes them all. Since in Islam, it is forbidden to forbid that which is permitted, a Muslim may choose to be a vegetarian, but only as an aesthetic or ethical consideration and not as a religious duty.

Rastafarianism

Rastafarians generally follow a diet called "I-tal", which eschews the eating of food that has been artificially preserved, flavoured, or chemically altered in any way. Many Rastafarians consider it to also forbid the eating of meat.

Hinduism

Hindus of certain castes are forbidden from consuming anything gained at the expense of an animal's suffering: e.g. meat, eggs, animal byproducts such as rennet and gelatin (including gelatin capsules) and honey. The milk of cows, buffalo and goats as well as dairy products (other than cheese containing rennet) are acceptable, as milk is given willingly. Leather from cows who have died of natural causes is acceptable. (Note: The diet of the orthodox Hindu also excludes alcohol, as well as "overly-stimulating" foods such as onions and garlic.)

• All dietary rules listed for Hindus apply to Jains, in addition to which Jains must take into account any suffering caused to plants and suksma jiva (Sanskrit: subtle lifeforms; refers to what would later be termed "microorganisms") by their dietary choices. They are forbidden from eating most root vegetables (e.g. potatoes) and deem many other vegetables acceptable only when harvested during certain times of the year.

• In Chinese societies, "simple eating" (素食 su4shi2) refers to a particular restricted diet associated with Taoist monks, and sometimes practiced by members of the general population during Taoist festivals. It is referred to by the English word "vegetarian"; however, though it rejects meat, eggs and milk, this diet does include oysters and oyster products.

Buddhism

Many Westerners think that Buddhist precept against killing implies that Buddhist should avoid eating the meat of animals. However, this is to miss the distinction between killing of animal and eating of already dead meat. And during the Buddha's time, there was no general rule requiring monks to refrain from eating meat. In Pali scriptures there are several recorded instance of Buddha eating meat, though whether Buddha died from eating tainted pork is disputed. In fact, at one point the Buddha specifically refused to make such a rule, declaring that one can eat meat as long as one do not hear, see or suspect that meat is specifically killed for oneselves. And these rules were invoked in relation to commercial purchase of meat in an episode involving General Shia. Buddha also stated that it is one's immoral conducts that make one impure, not the eating of meat, and declared meat eating as karmically neutral.

However the situation is very different in the case of Mahayana Buddhism. Though Mahayana Buddhism accepts Theravadan sutras as valid, in their own Mahayana sutras, the account of Buddha eating meat is absent. Secondly, at the time when Mahayana Buddhists were formulating their monastical rules, monks and nuns no longer received their food by begging. Instead, they lived in a monastery, where food were sent to them from outside by the lay community. So if meat was offered, it was specifically killed and prepared for monks, which violates Buddha's rule. Thirdly, Mahayana Buddhism places great emphasis on the Boddhisattva way, where the cultivation of compassion is the central focus of the practice. In Mahaparinirvana, it is stated that "the eating of meat extinguishes the seed of great compassion". In addition, a passage in the Lankavatara Sutra shows the Buddha inveighing strongly in favor of vegetarianism, though the historical accuracy of this passage is strongly disputed. Therefore, meat eating came to be greatly discouraged in early Mahayana schools. This is still the case in Chinese Buddhism, while many Japanese and Korean schools has adopted different interpretations of this issue. In Vajrayana Buddhism, tantric practice is said to purify one regardless of one's diet.

Therefore, in the modern Buddhist world, attitudes toward vegetarianism vary by location. In China and Vietnam, monks typically eat no meat. In Japan or Korea some school do not eat meat, while most do. Theravadan Sri Lanka and Southeast Asia do not practice vegetarianism. But more importantly, all Buddhists including monks are allowed to adopt vegetarianism if they wish to do so.

Baha´i Faith

In the Bahá'í Faith a vegetarian diet altought not required, it is preferable. Furthermore, Bahai´s believe "Fruits and grains" will be the foods of the future and the time will come when meat will no longer be eaten[1] (http://bahai-library.com/books/gandhi/node86.html).

Non-religious motivations

Ethics

Except for a small minority in the world today for whom meat is a staple food (principally, members of nomadic hunting or herding societies such as Inuit and Sami), everyone is free to choose whether to eat meat or not. Since a person can live perfectly healthily on a vegetarian diet, for most people the only motivations for eating meat are the pleasure of eating it, convenience, and tradition. "Ethical vegetarians" consider these reasons to be insufficient justification for the suffering they perceive to be entailed in the production of meat. Vegetarianism of this sort is often associated with the animal rights movement, although not all ethical vegetarians subscribe to the notion of animal rights.

Environmental or ecological concerns

The increase in world population combined with increased per-capita meat consumption[2] (http://earthtrends.wri.org/features/view_feature.cfm?theme=8&fid=24) is having a dramatic impact on the environment, and many say the current pace exceeds the ability of ecosystems to adapt.

The environmental impact of producing animal protein averages between 50% and 100% greater than the impact of growing the same amount of vegetable protein of similar quality.[3] (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=12936964&dopt=Abstract) The excess impact per animal calorie produced is even greater.

It results from the large amounts of grain used to feed livestock, pervasive overgrazing of lands by cattle and clearing of tropical forests for short-lived grazing lands while displacing indigenous people, large concentrations of manure coming from factory farms, methane from belching cattle, destructive fishing practices and fish farming.

Impacts include greater energy and water use, depletion of aquifers, pollution of streams and shorelines, land use impacts on wildlife and loss of tropical forests and the species that depend on them, global climate change from the methane, and the decline of fisheries worldwide.

Health

Statistics indicate that people on vegetarian diets have lower incidence of heart disease, cancer and osteoporosis. The American Dietetic Association says: "Although nondietary factors, including physical activity and abstinence from smoking and alcohol, may play a role, [a meat-free, vegetarian] diet is clearly a contributing factor" in reducing both morbidity and mortality "rates from several chronic degenerative diseases than do nonvegetarians."

Researchers like Dean Ornish have had successful results treating heart disease patients with strictly vegetarian diet, exercise and stress reduction programs. There are also nutritional considerations which encourage diets emphasizing fruit, vegetables and cereals and minimising meat and fat intake.

Dr Spock's seminal book, Baby and Child Care now recommends a vegetarian diet for young children for reasons of health. He also claims that most children also have an aesthetic dislike of meat and must learn to like it.

Aesthetics

Some people intuitively find meat unappetizing, particularly when raw, and simply prefer to abstain from the consumption of animal flesh for aesthetic or emotional reasons.

Pragmatic considerations

Modern-day, industrially produced meat is laced with chemicals, such as growth hormones, antibiotics, preservatives, food-coloring, and pesticides. Moreover, the meat of pen-raised animals, such as feedlot-fattened cows and pigs and farmed salmon, has much higher levels of fat and less nutritional value than the meat of their corresponding free-range or wild bretheren. Hence, many people are vegetarians not for ethical or aesthetic reasons but simply because meat nowadays has less nutritional value than it once had while plants have just somewhat less.

Social

Some people become vegetarian for social reasons. For instance, they may have a vegetarian family or partner and find that sharing vegetarianism makes cooking simpler or reduces diet-related friction in their relationships. Others live in a predominantly vegetarian region (such as Gujarat) where meat-eaters are a minority. Such persons may relapse into eating meat when the social reasons are absent, or they may become permanently accustomed to a meatless diet.

Vegetarian nutrition

Some important nutrients (amino acids, fats, vitamins A, D, K and E) are present in good quantities in meat, but with minimal attention a vegetarian diet with plenty of all of these can be designed. The American Dietetic Association states (http://www.eatright.org/adap1197.html): "Plant sources of protein alone can provide adequate amounts of essential amino acids if a variety of plant foods are consumed and energy needs are met." It is more common to find instances of scurvy and other consequences of vitamin C deficiency in people who subsist purely on a diet of fast food. However, it is important for vegetarians and vegans to be conscious of their intake of protein, B12, and other nutrients. Like any diet, one who eschews animal products needs to be balanced and include a variety of foods.

No diet is necessarily unnatural. Human beings have been omnivores since time immemorial; humans have the teeth (incisors and molars) and the digestive systems of creatures who eat both meat and plants. The eating of meat enabled energy. Nearly all the other higher primates are omnivores, except the gorilla. In the past, many people ate meat infrequently, because often it wasn't available or affordable. Strict vegetarianism is something comparatively new in human history.

There is a risk that Vitamin B12 deficiency can result from veganism. While just about all animal based foods contain useful quantities of B12, no readily available plant based source does (except the not universally available Indonesian fermented soy product tempeh). However, a range of foods have the vitamin added, including breakfast cereals, soft drinks, soy milk, Marmite, Vegemite and others. B12 supplements such as vitamin pills are often prepared from abattoir waste and are thus unsuitable for vegetarians, although there are an increasing number of brands that contain no animal products. B12 is stored in the body for many months, so B12 deficiency symptoms do not appear immediately on embarking on a pure vegan diet, but can eventually be severe. However this deficiency is rarely seen in Western vegans, since the problem is well-known.

One issue raised by choosing vegetarianism to avoid the suffering of animals is that agricultural cultivation of plant foods also harms animals. Run-off from fields harms aquatic life by polluting waterways with sediments, nutrients, and chemicals. Automatic farm machines kill small animals unintentionally, while cutting down trees takes away habitat for other animals. Pesticides kill beneficial and harmful insects alike. However, it should be noted that vegetarian diets require fewer agricultural resources than meat based diets. Thus, in populations where most of the meat consumed does not come from grazing animals a vegetarian diet will in fact reduce the suffering caused by agriculture because fewer plants overall will be necessary to sustain the diet.

Vegetarians (except fructarians) also kill plants in order to survive. Even though a vegetarian might contend that plants do not have the same sensory mechanisms to feel pain, some people feel that it is a worthwhile philosophical question. Even if plants are sentient, however, a vegetarian could argue that it is acceptable to consume the plant because otherwise the vegetarian would not be able to survive. This argument is similar to the argument that it is acceptable to kill animals if it is necessary for survival. For example, barring modern importation of foods, the Inuit live in a climate where consuming fish is necessary in order to get enough Calories to survive. Vegetarians point out that eating animals uses more plant matter than eating plants does, as animals are inefficient at converting plant matter into flesh.

Related beliefs

While vegetarianism is commonly defined strictly on the basis of dietary intake, many religiously, ethically or environmentally motivated vegetarians, in common with the animal rights and Green movements, try to minimise the harm done to animals in all aspects of their lives.

Many religiously motivated vegetarians consider the avoidance of skin contact with products made from body parts (e.g., leather, tallow soap) an integral part of their definition of vegetarianism. Others consider leather made from the skin of animals who died of natural causes acceptable. While for many Hindus it is impractical, there are those who shy away completely from the use of leather articles made from cowhide. Some state and cities in India have even banned cow-slaughter in places of pilgrimage or whole regions based on the sentiments of some Hindus.

Many health-motivated vegetarians are also associated with the organic food movement and/or are concerned about the use of genetically modified organisms in food production.
