This one wasn't as much fun or interesting as the Omnivore's Dilemma or Botany of desire. I liked his structure better for those titles. There is some rehashing of information from Omnivore and a lot of the other information I had picked up in other places. (Except that bit about the dentist doing research in the 30s - that was pretty interesting) He also discounts nutritional research while relying on it. I probably should have read the book in print to have the advantage of a bibliography or any notes. The reader's tone verged on smug, which did not serve the material well. It's good information if you haven't read The Omnivore's dilemma.
