I haven't. I've read some academic reviews of it, and basically it doesn't sound like the small amount of good research in it can tell me anything I don't already know (she cites Wikipedia, for pete's sake!). I think it's good that the book is out there, and it could help some people get away from a destructive lifestyle, but I'm living out my own vegetarian myth. I've suspected for years that my vegetarian lifestyle was doing more harm than good and more and more research is coming out confirming that. That said, it is so deeply embedded in my identity that it isn't going to be easy to change. Plus despite evolution, my body hasn't ever had the chance to develop some of the enzymes necessary to digest meat efficiently because I have never really been exposed to it, even in the womb. When I've had small exposure incidents in my life, it's made me pretty sick. Baby steps!
