Probably not much you do not already know about America’s industrial food chain and the manufactured food we consume at the end of it. You probably also already know the nutritional and environmental benefits of eating local. But, Pollan is still a great read for the deft way in which he weaves what we eat with philosophy, chemistry, history, economics, and the humanizing narrative of the people who provide our food. In typical Pollan fashion, however, the book contains about 20 percent more words than it really needs. May 2009.
