Humans become more productive with good health.
Yup, which is why veganism kills it. I don't know a single healthy vegan who wasn't already super-super healthy before he turned vegan, and only dropped to super-healthy. By contrast, all the "normal" vegans I know, and almost all "normal" vegetarians, have health problems that they blame on "unhealthy inorganic food" which I, natural omnivore, do not suffer from - surprise, surprise.
The huge increase in cardio-vascular accidents in developed countries are mainly due to the unnecessary and excessive consumption of animal protein.
Nope. They're mainly due to unnecessary and excessive consumption,
full stop. Animal protein doesn't come into it. In fact, most of the worst products in this regard are empty sugars and starches, which are perfectly vegan.
Humans become more healthy by consuming a higher ratio of plant to animal protein.
