not only that they also ate a bunch of other organs and combinations thereof, sometimes with the contents of the intestine still in the colon (often for the pregnant!) Primitive chemistry! They tailor made their babies from head structure to jaw size with their ancestral wisdom of the food around them. Nothing is a poison, everything is a tool, we just need to use the brain God gave us and not burn books (or people)...Throwing in a pile of conditional and tangential factoids doesn't prove anything.
The fact is that in primitive hunter gatherer cultures people do eat and relish fresh raw liver. After a kill it's shared and eaten first. Along with some intestine including digesta. >One of the delicacies among Indian hunters is the liver of a fat buffalo or deer that has become granulated from being overheated during a long chase. This is taken from the animal and sprinkled with the gall and devoured greedily raw.
They quickly noticed the trends of the foods they used. no distractions, just nature, family, medicine, food, hunting and their religion (and occasionally war) **still better than netflix**.
