Carlo Petrini gave a lecture at NCSU in Raleigh earlier this year. His talk was in Italian, but his ideas were universal: if we want happiness and peace, we're going to have to change the way we eat.
The book is fantastic. It is beautifully written, powerful, and balances scientific data and understanding with cultural histories and sensible aestheics. His proposal of a new branch of science, gastronomy, is as revolutionary as Freud's proposal to study the human psyche or David Kelley's efforts to study design as a science.
This book is The Inconvenient Truth for those who eat. But it is also a far more optimistic book, for the solution to the problem of industrial agriculture is to seek out good food, to meet and learn about the farms and farmers who grow it, and the reward is pleasure.
The Introduction by Alice Waters is, like the food at Chez Panisse, a sensual as well as a sensible delight.
This is a great book to buy, read, and then share with others, all around the world.
