I’m sorry, you may have misunderstood my point, I’ll try and be a bit clearer.
My point is that yes, exactly, people had a varied diet then and that a varied diet now is also a good idea. Experts in Paleo also believe and preach this. What she seems to be doing is taking a simplified view, not supported by people who have done a lot of good work in the area, as the thing to rail against.
Her agenda is to educate the people against the hype. The experts in Paleo also educate people against the hype. What would be good is to hear her educated and informed opinion on what the Paleo experts say and NOT the hype.
edit: On Paleofantasy this is worth a read The line that sums it up for me is: Paleofantasy shouldn’t have been a book in 2013, it should have been a blog post in 2010

No. In fact the invention of dwarf wheat by Norman Borlaug has quite probably saved more lives than anything but antibiotics, for which he won the nobel prize. Just a shame that gluten isn’t great for one.
