Thanks for posting this insteresting study.
No I had not seen this one
I have heard that pigs make a good analogue for human physiology and this certainly seems like a reasonable study... although we have to be aware that any definition of a Paleolithic diet is purely speculative; as we really don't know how our ancestors ate.
You might be interested in the Michael Pollan links that John (xMenace) includes in his signature block -- I recently read Pollan's "In Defence of Food" and he talks at length about how so much of our diet now comes from soy beans and corn... not just in the form of the processed foods that we eat ourselves, but also as fed to the livestock which provides our meat, eggs and dairy. In other words much of what is on offer in our stores is coming from a very limited nutrient base, grown in poor soil, while relying heavily on artificial fertilizers and chemical pesticides.
