The last time I saw Michael Pollan in a book, he was preparing to stalk a deer down in the forest or some such thing. I was starting the last chapter of _The Omnivore's Dilemma_ during a fairly turbulent flight when I looked up to find someone puking into one of those airsickness bags and that not only put me off airline peanuts but also somehow off books about food. But I decided to try again... 
 In this tome, Pollan spends a good amount of time tearing down the industry of "nutritionism": basically the practice of breaking food down into components in terms of telling people what and how much to eat. Instead, Pollan offers his own philosophy of food: "Eat food. Not too much. Mostly plants." "Food" is defined as something one of your remote ancestors would have recognized as food (as opposed to, say, ring pops or process cheese food product). Is there something ironic about tearing down the food advice industry and then dispensing your own advice instead? Probably.
