I posted this before -- here's yer kook website
"In other words, there is very little evidence that our guts are terribly
special and the job of a generalist primate gut is primarily to eat
pieces of plants."

He does come right out and say that our digestive system *did* evolve
with agriculture and processing (fermenting and cooking) of food, but
not anatomically -- which is what I meant by teeth and innards -- but
physiologically, with upregulation of amylase and persistence of lactase
into adulthood.
The point I'm trying to make is expressed in scientific language he
<http://www.jstor.org/stable/10.1086/300098?seq=2#page_scan_tab_contents>
"Both the 'faunivore' and the 'folivore' trend are morphological
specializations -- corresponding to different allometric relationships --
that, like all specialized characters, are unlikely to allow much
plasticity. A specialized carnivorous adaptation in humans that
would correspond to a minimized gut size is obviously not supported
by our data (fig. I). The large variations currently observed in human
diets (Hladik and Simmen 1996) are probably allowed by our gut
morphology as unspecialized "frugivores," a flexibility allowing
Pygmies, Inuit, and several other populations, present and past, to
feed extensively on animal matter, deriving most of their energy
from fat."
