Causes
Various religions forbid the consumption of certain types of food. For example, Judaism prescribes a strict set of rules, called kashrut, regarding what may and may not be eaten, and notably forbidding the mixing of meat with dairy products. Islam has similar laws, dividing foods into haram (forbidden) and halal (permitted). Jains often follow religious directives to observe vegetarianism. Some Hindus do not eat beef, and some Hindus, especially those from the upper castes consider vegetarianism as ideal, and practise forms of vegetarianism. In some cases, the process of preparation rather than the food itself comes under scrutiny. For instance, in early medieval Christianity, certain uncooked foods were of dubious status: a penitential ascribed to Bede outlined a (mild) penance for those who ate uncooked foods, and Saint Boniface wrote to Pope Zachary (in a letter preserved in the Boniface correspondence, no. 87) asking him how long bacon would have to be cured to be proper for consumption. The kapu system was used in Hawaii until 1819.
