The Health of Plains Indians
Dr Aleš Hrdlička -
Despite the wars and hardship they experienced, and the constant threat of smallpox and other epidemics, the nutrition of the nomadic Plains Indians tribes was among the very best in the world. Average height is an excellent measure of the general health and nutritional status of a population, and recent studies have shown that in the 19th century, the equestrian tribes of the Great Plains, including the Lakota, the Cheyenne, the Comanche, and the Blackfeet, were the tallest people in the world.
Much of the credit for this goes to the superior nutrition of the Plains Indian tribes. The hunter-gatherer lifestyle of the Plains Indian tribes resulted in an extremely varied and nutrient-rich diet. But the carbohydrate content of the diet was small, so these people lived their lives in ketosis. (Ketosis is using your fat burning metabolism rather than your glucose burning metabolism.)
Grass-fed bison meat was dense with important nutrients, including high levels of iron, protein, vitamin E, vitamin B-12, and others.
Plains Indians, like wolves and other animal predators, preferred older animals, due to the higher nutrition levels of the meat. They also made extensive use of organs, blood, bone marrow, and other parts in their diets. Neglected in modern American cuisine, these parts remain a staple in traditional diets around the world due to their extremely high nutrition levels. Marrow soups are a good introduction to these kinds of "by-products."
