Blood Groups and Diet

The four blood groups as we know them today are the result of 40,000 years of evolution of the human species.The man, who was originally exclusively a hunter (group O), evolved, first (about 20,000 years ago) learning to cultivate the land and feed on its fruits (group A) and subsequently (about 15,000 – 10,000 years ago) , on the heights of the Himalayas, becoming a nomad and taking care of livestock (group B). Finally, about 1,000 years ago, the AB group was formed, the only one not to be the effect of an evolutionary process, but of the mixture between the sedentary inhabitants of the Caucasian areas and the nomads from Mongolia.
