The Omnivore's Dilemma by Michael Pollan.
I read this book for the first time several years ago. But I think that it is one you should reread periodically. For me there is so much information that I seem to glean something new each time. Sometimes, I will just pick it up and read a section or two rather than reading the whole book again.
I guess you can already tell that I love this book. I like all of Michael Pollan's books and I think he has done a tremendous service to us all through his work.
I believe everyone should read this book at least once. It may not change the way you live but I guarantee it will make you think twice about a lot of things, when you drive past a cornfield, past a McDonald's, when you look at the organic section at the grocery store, even when you walk into Whole Foods. It is a thought provoking book.
'til next time...
