Query: Don't believe the hype.

Like many people have already said, this book is nothing but pure vegan propaganda, designed to brainwash people who are easily bowled over by the mere mention of a study that sounds remotely scientific. They try to "science-up" their own views on veganism, but their "scientific support" is nothing but fluff, if you check out their sources. No peer reviewed journals to back them up in sight. It is nothing but two foul-mouthed vegan chicks' attempt to persuade others to be like them (a little cult-like, in my opinion). My advice--don't be sucked into their autocratic nonsense and make up your own mind; don't let them make up your mind for you.I felt like I totally wasted my money. Usually I can find some redeeming qualities about products I buy. . . but not this one.
