Resurgent interest incommodities is linked to recent attempts toovercome the constraints posed by the binariesof economy/culture and production/consumption.Commodities and commodification represent acontentious convergence of economic, social,cultural, political, and moral concerns. Thisessay develops a conceptual framework forunderstanding this interconnectedness byexamining the relationship between commoditiesand our discourse, practices, and assumptionsabout food. We argue that the movement of afood artifact between local/global andglobal/local contexts is mediated by dynamicsof power and resistance that represent contestsof meaning regarding the criteria of that artifact's exchangeability. We apply (...) thisframework to the case of the tortilla, tracingits social life through an historical accountof its transformation from the staple food ofthe Mayan and Aztec people to its introductionas a fast food component of the diets of21st century Americans. This exampledemonstrates that food provides a powerful lensthrough which to trace and illustrate theinterconnectedness between material andsymbolic exchanges around the world that arecommonly associated with globalization.
