Fat is what has kept every group of people alive since the dawn of time without it we would be extinct, the Eskimo's live on it and if you take out all the chemicals from feed and ,steroids and meds they give animals today it is still good for you ... Pemmican is ground up dried buffalo or any meat mixed with whatever berries or nuts you could find and held together in a cake for by Fat! it is what kept the plains indians alive as well as Lewis and Clark etc. remember chewing the chicken leg knuckles off as a kid that stuff is good for you .....
