I recommend both the documentary & the book. If you want to know how to eat well, how to ditch diets, how to truly eat to live: look at this video & then snag the book. Pollan doesn't spout a bunch of hippy, granola nonsense (as my dad would have said). Pollan gives commen sense tips our grandmothers would have told us, and probably did. It boild down to the motto: Eat food, not too much, mostly plants. He doesn't call for you to raise your own chickens or eliminate meat, but he does want you to be aware of what is in your food, what you are eating, and how adversely it affects your health. Using this as a guide, hubby & I both lost more weight than we ever did on diets, and overall our health improved. HIGHLY recommend it.
