This article had confused references and was pretty deficient overall. Like the statement Protein was big in Paleolithic times, with up to 30% of the diet being meat -- much more than is recommended today, says Eaton. where even Cordain "The Paleo Diet" says "a little more than half - 55%" (pg 22) -- and other references cite higher.
