Offering a sweeping history of the ways humans have procured, processed, and consumed food, Bittman focuses on the political, social, cultural, and environmental consequences of the transformation from hunting and gathering to agriculture and of the increased industrialization of the food system. Like authors such as Jared Diamond and Yuval Noah Harari, Bittman asserts that agriculture 'sparked disputes over landownership, water use, and the extraction of resources' and has 'driven exploitation and injustice, slavery and war'.
