Horse Meat and Milk
No animal has had as profound an impact on human history as the horse. The journey begins in prehistory, with a small, shy animal that humans hunted for food. Hunters domesticated the horse in order to ensure a supply of meat and, later, mare’s milk, which is more nutritious than cow’s milk. This was a watershed event for both species, transforming the horse from an animal fleeing at a gallop from the mere smell of humans into the most valuable of their livestock. The horse’s need to roam far and wide for pasture prompted the horse herders to spread out across the Eurasian steppe.

Prehistoric hunters’ enthusiasm for horse meat had a solid basis in nutrition, too. In the cold, harsh environment of the last Ice Age, horse meat proved to be high in protein, and rich in fatty acids essential for health and growth. Compared to other meat, it contains less saturated fat. Humans can digest horse meat more easily. Partly for this reason, today’s Mongols favor horse meat to wean toddlers off mother’s milk. The rarity of horse meat in European and American cuisine reflects an eighth-century [C.E.] ban by the Catholic Church, in an era in which the newly evangelized Germans consumed horse meat as part of their old pagan rituals. How else to explain the disappearance of this delicious and nutritious food from Western diets?
