Every year McDougall holds Advanced Study Weekend in Santa Rosa. His scientific goto guy last year was Nathaniel Dominy PhD he stated that humans are starch eaters and have always been so, meat is a very small component of the human diet, always has been.
This year he trotted out Katharine Milton PhD. She trashed the paleo diet and has written papers objecting to basically the stupidity and falseness of the paleo concept of meat eating hunter gatherers. Apparently she thinks the research is careless and not interpreted correctly and the diet is basically another fad.
Anyways, I always like to see what the vegan avengers (Mcdougall, Furman, Ornish and so on) are thinking and spewing.
