My modest thoughts probably lead to an era when we were during the evolution. It was there that everything was formed, we chose animals that were easy to hunt, and in time we hunted more and more dangerous, but gave more food and satisfaction. Breeding and selection of which animal to eat, and which hold was most likely based on the suitability of an animal in our environment. It was there that most probably everything was formed, and the availability of animals of different species in a given region formed food cultures.
Nowadays, we are not so much addicted to hunting and meat selection, that's why there are those who do not need to eat it and there are those who like meat, but we do not need a strong choice anymore.
