Not knocking your post, but it always amazes me when researchers get the idea that since apes eat a certain way that humans will function optimally on the same diet. If you want to know what humans are biologically designed to eat it would make much more sense to study humans that live in the wild, not other primates.
That being said, plant/animal ratios vary from tribe to tribe pretty widely, although most tend to eat far more meat and fat than plants. Sticking to meat, fish, nuts, fruits, vegetables, and tubers is the way to go if you want to eat according to human design. Eating like an ape it would be a VERY hard, if not impossible, to get adequate calories and nutrients to fuel an active body.
