I read Bettyville recently too and liked it. Currently reading Vegan Betrayal since I'm always interested in topics of nutrition. Don't necessarily follow any particular diet anymore as all the info is so opposed to each other but this book had some interesting info about the value of fat and protein in our diets. According to the author, the long term effects of veganism are not known and can be disastrous healthwise for some. I tend to be a comitted omnivore these days but still find the arguments interesting.
