Why eat beef, pork, chicken etc but not dogs, cats etc

People’s choices about which animals to eat are shaped by a mix of factors: - Cultural norms and tradition: Dietary practices are learned and transmitted within communities. If a society has long eaten cattle, pigs, or chickens, those meats are normalized; animals kept as companions (dogs, cats) are taboo (Mary Douglas, Purity and Danger). - Utility and domestication: Animals bred for meat, milk, or work (cattle, pigs, chickens) have been selectively domesticated for food production. Pets often have different roles (companionship) and breeding histories that make them less suited to mass food systems. - Economic and practical reasons: Size, reproductive rate, feed conversion, and ease of slaughter make some species efficient food sources. Dogs and cats are typically less efficient or culturally protected. - Moral sentiment and empathy: Emotional bonds with companion animals generate stronger moral resistance to killing them. Species perceived as intelligent or socially close often gain special moral status (Peter Singer discusses differential moral weight). - Religious and legal rules: Religions and laws prohibit or permit specific animals (e.g., kosher rules forbid pork; some societies ban dog meat). - Health and safety: Some animals may carry diseases or parasites that make them hazardous as food without specific controls; local knowledge influences which are considered safe. In short: a complex blend of cultural, practical, moral, religious, and health reasons determines why some species are commonly eaten while others are not.

Short explanation Societies distinguish edible animals from taboo animals for a mix of practical, cultural, symbolic, and moral reasons. Practical factors (availability, ease of domestication, diet and disease risk, and usefulness in other roles) shape which species people raise for food. Cultural meanings, religious rules, and social identity then codify preferences into norms: certain animals become “food,” others become companions, workers, or sacred beings. Over time legal, economic, and emotional practices reinforce those lines. Longer, more detailed explanation 1. Practical and ecological factors - Domestication potential: Humans historically ate species that could be domesticated—cattle, pigs, sheep, goats, chickens—because they breed well in captivity, convert local vegetation into edible protein, and tolerate human presence. Jared Diamond’s work on domestication (Guns, Germs, and Steel) explains why only a handful of large mammals became widespread livestock. - Efficiency and diet: Ruminants (cattle, sheep, goats) can digest grasses humans cannot, turning low-quality forage into meat and milk. Pigs are omnivorous and adaptable, allowing them to thrive in many environments. Animals that are inefficient to raise, reproduce poorly, or require diets costly to supply are less likely to become staples. - Disease and food safety: Some species carry diseases that make them risky to eat or handle. Zoonoses and parasites historically deterred consumption of certain wild species or required specific preparation methods. - Utility beyond meat: Animals used for transport, labor (horses, oxen), wool (sheep), or as pest control can be valued more alive than slaughtered. Killing such animals would reduce long-term benefits. 2. Cultural and symbolic factors - Social meaning: Food choices signal identity. What a group eats marks cultural boundaries—ethnic, regional, or class differences. Distinctive taboos (e.g., pork avoidance in Judaism and Islam) help consolidate group cohesion and identity. - Religious injunctions and sacredness: Many dietary prohibitions stem from religious rules that sacralize or forbid certain animals (e.g., cows in Hinduism; pigs in Judaism and Islam). These rules may have theological, symbolic, or historical rationales and are often durable because they are tied to belief and ritual. - Pollution and purity frameworks: Mary Douglas’s classic anthropological argument (Purity and Danger) sees food taboos as part of systems that classify the world; animals that blur categories (e.g., animals that both live on land and water) can be viewed as impure. - Aesthetic and emotional factors: Animals that are commonly kept as companions (dogs, cats) elicit emotional bonds, empathy, and moral concern, making their consumption taboo in many cultures. Familiarity breeds moral consideration: the more integrated an animal is in everyday life, the less likely it is to be considered food. 3. Historical contingency and path dependence - Once a pattern is established, social institutions, culinary techniques, markets, and laws reinforce it. If a community has centuries of raising cattle and slaughterhouses geared to cattle, it’s unlikely to switch to other species except under pressure. - Colonial encounters and globalization reconfigure tastes—introducing new animals or marginalizing others—showing that food taboos are not fixed but historically contingent. 4. Moral and ethical reasons - Moral status: Philosophers debate whether moral distinctions between species are justified. Some argue that sentience and capacity to suffer should guide moral consideration (utilitarian/animal welfare perspectives), suggesting consistency would require similar treatment across species. Others appeal to relational ethics: animals with whom we have relationships (pets, work animals) acquire special moral protections. - Consistency problems: Eating some intelligent, social animals (such as pigs) while protecting others (dogs) raises ethical puzzles. Many ethicists encourage reflection on why species membership often functions as the decisive moral boundary rather than capacities or relationships. - Cultural moral frameworks: Different moral systems weight factors differently—religious law may prohibit pork for ritual reasons while allowing other meat; secular vegetarians may avoid all animal products because of concern about suffering. 5. Legal, economic, and institutional reinforcement - Laws: Regulations define which animals may be slaughtered and sold for human consumption. Cultural norms become codified (e.g., bans on dog meat in some countries, protection of certain species). - Markets and infrastructure: Supply chains, slaughter facilities, culinary traditions, and consumer demand create economic lock-in. Introducing a new meat faces not just taste obstacles but regulatory, logistical, and marketing ones. 6. Change and variation across cultures - What’s taboo varies widely: dog meat is eaten in some cultures and taboo in others; horses are food in parts of Europe and taboo in the English-speaking world; shellfish are forbidden in some religions but prized in others. This variation shows that categorizations are culturally constructed, not determined solely by biology. - Global trends: Urbanization, animal welfare movements, health concerns, and environmental pressures (e.g., climate impacts of beef) are changing attitudes toward certain meats and promoting alternatives (plant-based or insect protein), demonstrating that eating practices evolve. Takeaway The distinction between animals we eat and animals we don’t is shaped by overlapping practical, cultural, symbolic, ethical, legal, and economic forces. While some reasons (domestication, nutrition, disease) are grounded in ecology and technology, many decisive factors are social and historical—meaning the boundary is contingent, contestable, and capable of change.
