I just finished "Near a Thousand Tables", by Felipe Fernandez-Armesto, which is subtitled "A History of Food." It was interesting and anthropological -- and the writer evidently loves food, which makes for good reading. From the invention of cooking, to plant- and animal-breeding, to the great world movement of foodstuffs to their non-native parts of the world, to modern-day issues around genetic modification and the Green Revolution, it makes for a good read.
I would appreciate any other recommendations for such historical reading. Three others I would recommend:
Fast Food Nation by Eric Schlosser is a terrific, polemical-but-shy-of-dogmatic account of the rise and operations of fast food franchises and my favorite book about food;
Botany of Desire by Michael Pollan isn't only about food, but about human interactions with apples, potatoes, marijuana, and tulips and very entertaining;
The Vanishing Land by Robert West Howard is an interesting history of the development of the food industry and farming in the U.S. particularly.
