Some new videos answer her. There are four about The China Study and her criticisms of it. And four about Ancel Keys and his oponents who say that he was wrong about saturated fat. There are 71 videos in total. Each one I've watched has fascinating information and lots of facts. The man who produced them has done sterling work in defending veganism.
This video is about Ancel Keys. You can find the others there by searching for Primitive Nutrition 62: China Studies, Part I. The others about that study are numbered 63, 64, 65.http://www.youtube.com/watch?v=NDwjkv1FW5g
Oh, and the first video of the whole series has some familiar faces in it.
