Dr. Weston A. Price was a prominent dentist known primarily for his theories on the relationship between nutrition, dental health, and physical health. Although controversial, we can learn many things from his work and research including never to ignore what your ancestors ate.
There is often a direct correlation between the diet strategies of our ancestors and the success of our diet plans today. Stating that "human beings do not need to eat any plants to be healthy" is very one-sided and general statement which does not address the needs of all cultures around the world, their environments, resources or ancestral lines. Consequently, although there is some evidence to confirm this statement, it may not be a factual for many populations on earth.

Another very important point is that the tribes and populations studied by Dr. Weston Price were consuming meats which were fresh and not decayed, processed or chemically injected as many of the meats available through the meat industry are today. Most of the animals also ate non-GMO food products and thrived in their natural habitat. For this reason alone, it is impossible to make comparisons of tribal populations, their health and subsistence to populations in developed nations and their modern meat consumption.
