Reader Tim has recommended an outstanding book in comments on the last post.
The book is Imagining Head Smashed In
The standard-paleo "lean meats" thing has always bugged me, it just makes no sense. In Brink's "Imagining Head Smashed In", a scholarly work on his decades' long excavation of an ancient Bison Jump on the Great Plains, it is made clear that the Blackfoot tribes were after the fattiest parts of the fattiest animals. These bison jumps were huge assembly lines for the harvest of fat. Bones were crushed and boiled in hide-lined pits to extract the maximum fat. Early European contact left reports that the Native Americans would do all that could be done to obtain bison fat, wasting lean to get fat.
It's a great read and very applicable to Paleo 2.0 thinking.
Love to get some more input on this book and some Paleo 2.0 buzz going about it! J. Stanton at Gnolls.org gave it a read and a positive review. It's an eye opener to say the least.
Reading any book that claims "lean meats" were preferred by any ancestral population, or indeed any group that predates Ancel Keys and the ensuing epidemic of skinless chicken breasts, just makes you wonder.
Do such writers actually observe what people prefer to eat, or read the historical record, or apply what they already know about foraging theory and the energy density of fat?
Anyway, this is a great book which I was planning to review, but along with dozens of others, I haven't finished it yet. But I've read enough to second Tim's endorsement. A great read.
