Vegetarian)
- 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 (terminology)
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, honey), 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 traditional 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 thus 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.
In current English, the term "vegetarian" is occasionally used for retricted diets that nevertheless include some types of meat. Usually these deviations from traditional usage are made casually, perhaps for lack of a better word. The resulting confusion of terms can create awkard situations for more strict vegetarians, 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.
In 1847, attendees at the meeting of the first Vegetarian Society in Ramsgate, England, agreed that a "vegetarian" was a person who refuses to consume flesh of any kind. Prior to that time, vegetarians had often been called Pythagoreans, after an ancient sect that also abstained from meat (and beans).
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, some Islamic scholars conclude that vegetarianism is forbidden. Muslim vegetarians and their supporters, however, make a distinction between choosing not to do something and forbidding it, and argue that a Muslim may choose to be a vegetarian, but 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.
Taoism
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.
A belief that continues in Theravada Buddhism from its Vedic roots is that the killing of larger animals results in more bad karma than that of smaller ones, e.g. that it would be less bad to kill a chicken than a cow. This is due to the greater intention and effort required to kill the larger animal. Furthermore, fish are considered of lesser importance than mammals.
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 schools do not eat meat, while most do. Theravadan Sri Lanka and Southeast Asia do not practice vegetarianism. All Buddhists however, including monks, are allowed to practice vegetarianism if they wish to do so.
Bahá´í Faith
In the Bahá'í Faith a vegetarian diet, although not required, is often considered preferable. Furthermore, Bahá'ís 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
Aesthetic and emotional
Some people find meat, animal products, and their production unappetizing or emotionally disturbing.
Environmental
Many people believe that the production of meat and animal products at current and likely future levels is environmentally unsustainable. It is also argued that even if sustainable, modern industrial agriculture is changing ecosystems faster than they can adapt. While vegetarian agriculture produces some of the same problems as animal production, the environmental impact of animal production is significantly greater. [2] (http://www.ajcn.org/cgi/content/full/78/3/664S)
Free-range animal production requires land for grazing, which has prompted encroachment on undeveloped lands and clear cutting. The move into wild lands has increased the rate of species extinction and damaged the services offered by nature, such as natural processing of pollutants. Overgrazed lands lose their ability to support animal production, which makes further agricultural expansion necessary. Factory farm animal production, while having a smaller land-use footprint, requires large quantities of feed that must be grown over large areas of land. Both free-range and concentrated animal production require large quantities of freshwater and energy, which are currently taken from nonrenewable sources such as aquifers and fossil fuels. Animal production also creates damaging animal waste. In the United States (the world's largest emitter of greenhouse gases) livestock account for nearly 20% of total methane emissions. [3] (http://www.epa.gov/methane/sources.html)
Ethical and animal rights
Some people believe that the production and consumption of meat and animal products are inappropriate treatments of animals. Reasons for believing this are varied, and may include a belief in animal rights or an aversion to inflicting harm on other living things. Some people believe the treatment animals receive in the production of meat and animal products justifies never eating meat or animal products, even if alternatives do not exist. Others believe that if alternative means of survival exist, it is ethical to choose an alternative, such as vegetarianism. With the exception of a small minority of people, e.g., nomadic hunting and herding societies such as the Inuit and Sami, everyone is free to choose not to eat meat or animal products.
Health
According to reputable sources such as the American Dietetic Association, American Heart Association, British Medical Association, and the Mayo Clinic, vegetarian diets offer a number of health benefits compared to non-vegetarian diets. Vegetarians as a group compared to non-vegetarians have lower body mass indices, lower levels of cholesterol, lower blood pressure, and less incidence of heart disease, hypertension, type 2 diabetes, some forms of cancer, renal disease, dementia, and osteoporosis. [4] (http://www.eatright.org/Public/GovernmentAffairs/92_17084.cfm) [5] (http://www.americanheart.org/presenter.jhtml?identifier=4777) [6] (http://www.mayoclinic.com/invoke.cfm?id=HQ01596)
Social
Some people are vegetarian because they were raised by vegetarians. Others may have become vegetarians because of a vegetarian partner, family member, or friend. Some people live in regions that are predominantly vegetarian (such as Gujarat), making meat-eaters a minority. When removed from the social influences that cause vegetarianism, some people will stop being vegetarian while others will remain vegetarian.
Vegetarian nutrition
With planning, a vegetarian diet can be as nutritious as a well-planned diet that includes meat and animal products. Unplanned vegetarian diets may encounter deficiencies in iron, omega-3 fatty acids, complete proteins, and Vitamins A, B12, and D.
Iron
Meat is the only source of heme iron; plants contain non-heme iron. The human body absorbs non-heme iron less efficiently. Non-heme iron is also more sensitive to both inhibitors and enhancers of iron absorption. Vitamin C is an iron absorption enhancer. Iron absorption inhibitors include tannins (tea, wine), phytates (legumes, grains), calcium and polyphenols. Iron is an integral part of many proteins and enzymes that maintain good health. In humans, iron is an essential component of proteins involved in red blood cells' oxygen transportation. Iron also helps regulate cell growth and differentiation. Excess amounts of iron can be toxic and even result in death.
Omega-3 fatty acids
Seafood and eggs are the primary sources of omega-3 fatty acids. Vegetarian sources of omega-3 fatty acids include flaxseeds and flaxseed oil, walnuts and canola (rapeseed) oil. Vegetarian sources of omega-3 fatty acids are likely to have lower concentrations of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), two long-chain essential fatty acids. The body can synthesize small quantities of EPA and DHA from other omega-3 fatty acids, such as alpha-linolenic acids, which are present in vegetarian sources of omega-3 fatty acids. The body can also convert DHA into EPA. DHA supplements derived from DHA-rich microalgae are available. While there is no scientific consensus on the role of omega-3 fatty acids, it is generally believed that they may reduce the risk of coronary heart disease, stabilize mood and prevent depression, and reduce the risk of dementia in older age.
Protein and essential amino acids
Meat is a good source of high-quality protein. People who remove meat from their diet must make up the appropriate quantity and quality of the protein lost with other protein sources to remain in good health. Protein is essential to both the structure and function of all living cells. Protein derived from animals is complete, i.e., protein that contains all the essential amino acids that the human body cannot synthesize on its own. The only plant that can produce complete protein is the soybean plant. A number of plants produce incomplete proteins, i.e., protein that contains one or more, but not all, of the essential amino acids. If soy is not a key part of a vegetarian's diet, eating a wide variety of vegetarian foods that contain protein will ensure adequate amounts of each essential amino acid.
Vegetarian sources of complete protein:
Vegetarian sources of incomplete protein:
Vitamin A
Meat is the only reliable unfortified source of preformed Vitamin A. The human body can synthesize Vitamin A from provitamin A carotenoids, which are present in some plants. The carotenoid the human body most efficiently converts to Vitamin A is beta-carotene. Vegetarian sources of preformed Vitamin A include foods fortified with Vitamin A and supplements that contain Vitamin A.
Vegetarian sources of beta-carotene:
Vitamin A plays an important role in vision, bone growth, reproduction, and cell division and differentiation. Vitamin A helps maintain the surface linings of the eyes and the respiratory, urinary, and intestinal tracts, which protect again bacterial infection. Vitamin A also helps maintain the integrity of skin and mucous membranes that function as a barrier to bacteria and viruses. Vitamin A may help lymphocytes, a type of white blood cell that fights infections, function more effectively. Some carotenoids, in addition to serving as a source of vitamin A, have been shown to function as antioxidants in laboratory experiments. However, this role has not been consistently demonstrated in humans.
Vitamin B12
Meat, eggs, and dairy products are the only reliable unfortified sources of Vitamin B12. Vitamin B12 is produced only by bacteria found in animals. While humans, as animals, also contain these bacteria, they are located so far down the intestine that the body is unable to absorb the Vitamin B12 they produce. Vegetarian sources of Vitamin B12 include eggs, dairy products, foods fortified with Vitamin B12 and supplements that contain Vitamin B12. Vitamin B12 is necessary for DNA replication, so deficiencies can prevent rapid cell division, particularly of blood cells, which causes anemia. The human body also uses Vitamin B12 in the natural protein sheaths around nerves, so deficiencies can lead to potentially irreversible nerve degeneration.
Vitamin D
Meat and fortified dairy products, especially fortified milk, are common sources of Vitamin D. The human body can also synthesize Vitamin D when skin is exposed to ultraviolet radiation from the sun. Vegans with little exposure to the sun's ultraviolet radiation, e.g., those living at latitudes close to the poles, are vulnerable to Vitamin D deficiencies. Vegan sources of Vitamin D include the sun's ultraviolet radiation, foods fortified with Vitamin D, e.g., cereal, and supplements that contain Vitamin D. Vitamin D acts as a hormone, sending a message to the intestines to increase the absorption of calcium and phosphorus, which produces strong bones. Vitamin D also works in concert with a number of other vitamins, minerals, and hormones to promote bone mineralization. Research also suggests that vitamin D may help maintain a healthy immune system and help regulate cell growth and differentiation.
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.
