Pollan gives us a massive amount of info about where our food comes from and how our food production systems sustain themselves (or not...).
His writing is entertaining, anecdotal, and matter-of-factual, rather than alarmist or dooms-dayish. Pollan's "Omnivore's Dilemma" is a must read for anyone pondering about what makes an ethical food choice for good health - both for the good of our own bodies and that of planet Earth.
It's not till towards the end that Pollan turns seriously to the subject posed in his title... the omnivore's dilemma. The book really gets to the heart of things at this point. His thoughts on animal cruelty, especially, shed a lot of light on this highly fraught subject.
All in all, I thought this an excellent nonfiction book with plenty of food for thought. But then, I'm a foodie...
