I see only page one of the paper, if more can be read please tell me how.

 From that page, it is merely more Cordain-driven nonsense of those who 
cannot see that we are obligate carnivores. "...need to moderate the 
high nitrogen levels of [b]lean[/b] meat and the role that plants *may* 
play in achieving that moderation."

This is Cordain's crazy lean meat hypothesis again, when we know that 
hunters who had a choice left such for the wolves. It is dog food.

There is no evidence on that page; the author even calls it "speculative".
