New (or rather slightly old) post by Don Matesz at http://donmatesz.blogspot.com/.
Its a 3 part series, and contains a lot of convincing argument that too much meat is bad for bones. I thought only balancing protein was enough, but it seems Kitavans are not a fluke but a very low meat diet is actually healthier than a low carb diet.
Eskimo bones tested in the research papers date to around 1500AD and even one from 400AD. All had osteoporosis. The bone density was lesser than an aged matched Caucasian. Guys and Gals on Zero carb or VLC you might want to get your bone density measured, to be on the safe side.
The article is very interesting, and is ground breaking just like the Primal Potato series. I guess he is almost as good as Stephan. Even Stephan follows his blog very closely.
