Animal genetic resources for food and agriculture crop and livestock species in the early neolithic time period changed our human evolution and lifestyles. This ability to control food production led to major demographic, technological, political and military changes. Consecutively, thousands of years of natural and human selection, genetic drift, inbreeding, and crossbreeding have contributed to the diversification of animal genetic resources and increased the variety of environments and production systems that livestock keeping takes place. Relatively few species have been domesticated; out of the world's 148 non-carnivorous species weighing more than 45 kg, only 15 have been successfully domesticated.

Food and drink prohibitions fairly recent addition to cultural food prohibitions is the meat and eggs of endangered species or animals that are otherwise protected by law or international treaty. Examples of such protected species include some species of whales, sea turtles, and migratory birds. Similarly, sustainable seafood advisory lists and certification discourage the consumption of certain seafoods due to unsustainable fishing. Organic certification prohibits certain synthetic chemical inputs during food production, or genetically modified organisms, irradiation, and the use of sewage sludge. The Fair Trade movement and certification discourage the consumption of food and other goods produced in exploitative working conditions. Other social
