Low levels of chronic metabolic acidosis is a common phenomenon in the Western world. Most people that eat the standard American diet are in a state of chronic acidosis and are not aware of it.
Stereotypical representation of Neanderthals pictures them as killing the woolly mammoth.
However, Neanderthal teeth tell a different story.
The significant discovery came when scientists analyzed the remains of Neanderthals from El Sidrón, Spain. The Neanderthals from El Sidrón showed zero signs of meat consumption. Not some small amount but complete round zero.
There is no absolute correlation between meat-eating and intelligence. The manner of combining some amount of foraged meat to the predominantly vegan diet did not become a pivotal force in the emergence of modern humans.
Our physiology evolved from small plant-eating mammals for a time span of 60 million years, and we had been using a hunting strategy for 200,000 years. There is a belief that besides foraging, hunting is also a natural human activity and that our natural diet is congruent with both hunting and foraging. We must understand the difference between these two. These are two completely different diets.
