Bingo, Lorenzo!  Humans might be able to eat a bit of grass from time to
time, but with only one stomach, we can't rely on grass as a staple.  But
"The Origin Diet" author apparently says grass was a staple in many anchient
diets.  I'd love to know where she got THAT.  But sorry, I'm not going to
buy a copy of the book to find out; I've got more important uses for my
hard-earned cash.
