what do you mean here by protein toxicity?

it is low energy (because of little fat)

eat more of them. Howevr, i will resile from my statement that kangaroo is
an ideal paelo food. i would imagine emu and goanna would be better.

in the absence of dietary glucose the proteins are catabolised into glucose.
The brain also uses the amino acid glutamine and fatty acids for fuel.

Where are your tuber tribes that prove your point? Which paelo culture lived
predominantly on tubers? can't you name any?
