Despite the in-vogue arguments that come with sparse evidence to support that a vegetarian diet can indeed match the athletic predisposition and performance of a non-vegetarian one, I find it highly suspect that regions of the world ( including India ) which have had to rely exclusively on plant protein for hundreds of generations would yield the same athleticism predisposition rates as regions that haven't had such a constraint.

Consistently high preponderance in vegetarianism (in India) has to share some of the blame for a lack luster interest in athleticism and athletic activities.

There is simply no other very large land mass that has a cultural history of very high (and almost exclusive) dependence on plant protein.

This does not even begin to tell the tale of the deleterious effects of a diet entirely devoid of testosterone-laden red meat.
