Michael Pollan.

Recommended by Dan Dennett in a lecture at the University of Edinburgh (17:15) about free will and determinism. Supposedly about the world food system and what's wrong with it, and how we might make it better. Listed under 'Further Reading' at the end of Daemon. I've also run into some controversy about it, just obscurely while reading about Natalie Portman's veganism and activism, and that the book that convinced her to become a vegan is at odds with this one.
