One of those rare books that enlightens and entertains at the same time. Pollan is an intellectual heavyweight and a gifted writer. I decided to read this after hearing about it in the equally excellent 'Eating Animals' by Jonathan Safran Foer. I would recommend both these books to anyone who has ever given a thought to what they choose to eat. This universal topic is discussed on many levels: practical, environmental, social and cultural, philosophical... All discussions are balanced and at no time do either books come across as preachy. Well worth reading!
