Matzah, Meat, Milk, and Mana

Abstract

Religio-cultural groups endorse an astounding diversity of beliefs and rituals regarding food. The authors theorize that such practices in part originate and persist because they (a) mark in-group membership through the consumption of unique foods and the establishment of common food rituals, (b) signal status through fasting or ingesting certain foods or large quantities of food, and (c) help individuals avoid disease by promoting or prohibiting specific foods that were historically available. Moreover, the authors theorize that these sociofunctional motives are grounded in essentialist beliefs about the discreteness of biological kinds and/or beliefs about unseen spiritual essences, transmitted through food or food preparation. They consider how psychological explanations of religio-cultural food prescriptions and prohibitions may or may not map onto religious explanations. The authors also offer testable hypotheses about where and why certain food practices may originate and persist, and they hope that this analysis is the kind that provides insight into factors that may have shaped a wider range of religio-cultural beliefs and practices.
