I’ve been having a hell of a time finding trustworthy cites on this, possibly because there are so many groups with identity stakes in the matter—obesity researchers and advocates, vegetarians, and paleo diet adherents all have somewhat conflicting interests in ancestral nutrition. That said, this survey paper describes relatively modern hunter-gatherer diets ranging from 1% vegetable (the Nunamiut of Alaska) to 74% vegetable (the Gwi of Africa), with a mean somewhere around one third; no entirely vegetarian hunter-gatherers are described. This one describes societies subsisting on up to 90% gathered food (I don’t know whether or not this is synonymous with “vegetable”), but once again no exclusively vegetarian cultures and a mean around 30%.
I should mention by way of disclaimer that modern forager cultures tend to live in marginal environments and these numbers might not reflect the true ancestral proportions. And, of course, that this has no bearing either way on the ethical dimensions of the subject.
