Vegetarianism
The word vegetarian first appeared in print during the early 1830s, though its roots stretch back to older concepts of vegetable regimens. Fanny Kemble used the term in her Journal of a Residence on a Georgian Plantation between 1838 and 1839, marking one of the earliest documented uses. The Oxford English Dictionary notes that the word entered general circulation after the founding of the Vegetarian Society in Manchester in 1847. Before this formal organization existed, authors described diets based on vegetables without using the specific label. The term itself combines vegetable with the suffix -arian, similar to how agrarian describes land use. Historical records show examples from 1839 and 1842 where writers discussed healthy vegetarians or their dietary choices. Alcott House, a school opened by James Pierrepont Greaves in July 1838 near Ham Common in London, published pamphlets called The Healthian starting in 1841. These publications contained some of the earliest appearances of the word vegetarian in written form. Modern dictionaries trace the origin to an irregular compound of vegetable and -arian, meaning supporter or believer.
Ancient religious movements across India and Greece established meat abstinence as a spiritual discipline centuries before modern terminology emerged. Parshwanatha and Mahavira revived Jain vegetarianism between the 8th and 6th centuries BCE, promoting ahimsa or nonviolence toward all living beings. The Acharanga Sutra from the 5th century BCE forbade monks from walking on grass to avoid killing insects dwelling within it. In ancient Greece, the Orphic movement spread vegetarian practices during the 6th century BCE for ritual purification purposes. Pythagoras promoted altruistic doctrines involving metempsychosis, though historical accounts suggest he sometimes ate meat himself. Emperor Tenmu issued bans on killing and eating meat in Japan during 675 CE, specifically targeting the busy farming period between April and September. These early prohibitions excluded wild birds and animals while protecting livestock needed for agriculture. Buddhist cuisine became popular during China's Song dynasty, where chefs created meat analogues using beans, gluten, root vegetables, and mushrooms. Tofu, seitan, and konjac originated in Chinese Buddhist kitchens as substitutes for pork, fowl, eggs, and crab roe. Medieval European monastic orders restricted meat consumption for ascetic reasons but rarely banned fish entirely. The medieval definition of fish included seals, porpoises, dolphins, barnacle geese, puffins, and beavers.
A lacto-vegetarian diet includes dairy products and honey while excluding eggs and flesh. Ovo-vegetarian diets incorporate eggs and honey but omit all dairy sources. Lacto-ovo vegetarians consume both dairy and eggs alongside plant foods. Veganism represents the strictest form by excluding all animal products including leather shoes and silk clothes. Fruitarianism permits only fruit, nuts, seeds, and plant matter gathered without harming the source plant. Macrobiotic diets consist primarily of whole grains and beans with minimal processed ingredients. Sattvic or yogic diets exclude red lentils, durian, mushrooms, alliums, blue cheeses, fermented foods, alcoholic drinks, coffee, black tea, green tea, chocolate, nutmeg, and excessively pungent spices. Raw veganists heat food no higher than 42 degrees Celsius using dehydrators rather than conventional cooking methods. Some individuals label themselves vegetarian while practicing semi-vegetarian approaches that include fish or poultry. Pescetarianism allows seafood consumption while avoiding land animals. Pollotarianism restricts meat to chicken and possibly other poultry species. Flexitarian diets reduce animal flesh intake as a transition strategy toward complete abstinence. Economic considerations sometimes drive these choices when meat costs exceed available budgets.
The Academy of Nutrition and Dietetics states that properly planned vegetarian diets remain healthful at all life stages. Vegetarian diets typically offer lower saturated fat, cholesterol, and animal protein levels compared to omnivorous alternatives. They provide higher amounts of carbohydrates, fiber, magnesium, potassium, folate, vitamins C and E, and phytochemicals. A 2019 review found vegetarians have lower bone mineral density at the femoral neck and lumbar spine than non-vegetarians. Infants fed lacto-vegetarian diets showed normal growth patterns according to a 2020 meta-analysis. No significant differences in child development emerged between vegetarian and meat-eating groups in a 2021 study. Meta-analyses report reduced risks of death from ischemic heart disease and cerebrovascular disease among vegetarians. Some reviews suggest possible associations with depression and anxiety particularly among individuals under 26 years old. Other studies found no significant links between vegetarian diets and mental health disorders. A 2012 study indicated reduced all-cause mortality risk for vegetarians with significantly lower ischemic heart disease mortality rates. Vitamin B12 deficiency remains a concern since it does not naturally occur in plants. Lacto-ovo vegetarians obtain B12 from dairy products and eggs while vegans rely on fortified foods or supplements. Iron bioavailability differs between plant sources and meat despite similar total iron content. Consuming vitamin C-rich foods like citrus fruits, tomatoes, broccoli, or black beans enhances iron absorption. Calcium intake can match non-vegetarian levels if diets include milk, yogurt, cheese, or fortified plant milks. Broccoli, bok choy, kale, calcium-set tofu, almonds, okra, dried figs, tahini, and soybeans provide usable calcium. Mushrooms exposed to ultraviolet light generate substantial vitamin D2 content reaching up to 80 micrograms per serving.
A 2006 United Nations initiative identified the livestock industry as one of the largest contributors to global environmental degradation. Modern animal agriculture practices contribute massively to air pollution, water contamination, land destruction, climate change, and biodiversity loss. The sector accounts for approximately 18% of worldwide greenhouse gas emissions measured over 100 years. Enteric fermentation and manure management represent about 3.1 percent of US anthropogenic greenhouse gas emissions. Factory farming systems raise ethical concerns regarding animal welfare and human labor conditions within industrial settings. PETA promotes vegetarianism partly to offset poor treatment and working conditions faced by slaughterhouse employees. Agriculture ranks among the three most dangerous jobs globally according to International Labour Organization statistics. Accidents including pesticide poisoning increase mortality risks for farmers and plantation workers. Economic vegetarians avoid meat due to cost considerations or beliefs that reducing consumption eases healthcare burdens. Mass reductions in meat intake could improve public health while allowing rangelands and grainlands to rejuvenate. Lowering global meat consumption makes grain more affordable for chronically hungry populations. A 2009 decision in Ghent, Belgium made it the first city to implement weekly meatless days for civil servants and schools. Posters encouraged participation while veggie street maps highlighted available restaurants. Public acceptance improves when descriptions focus on flavor rather than health benefits alone.
India maintains the highest percentage of vegetarian residents globally with estimates ranging from 20 to 40 percent depending on methodology. Mexico holds the second highest percentage of vegetarian population worldwide. The Netherlands reports relatively low levels at approximately 5 percent of its citizens.

Haridwar enforced similar restrictions starting in 2002 which remained upheld by India's Supreme Court until 2004. Palitana implemented a ban on meat sales in 2014 within Gujarat state boundaries.

Shashamane in Ethiopia's Oromia Region exemplifies another heavily-vegetarian location globally.
