The Omnivore's Dilemma
The Omnivore's Dilemma by Michael Pollan starts off strong but with each major section gets less informative and more autobiographical. This isn't to say that the later sections don't have worthwhile material, it's just that what material they do have is harder to find and not as thought provoking. I suspect if the book had started off with his tales of novice hunting and mushroom gathering I wouldn't have read the rest of it.
The writing style of each major section does match its theme. Which is why I may have found the Industrial (scientific) section the most interesting, while the Pastoral (pseudoscience) less so, and the Personal (new age) a chore to read. Despite the major differences in the quality of the material the book does prompt one to consider where your food comes from.
