I read a story where a primitive hunter, after shooting a Buffalo or something, grabs out the liver (giving some to his dog) and squeezes some bile from the gallbladder on the liver like you might squeeze a lemon, eating this mix raw.
But bile is bitter tasting right? Wouldn't that suggest bile shouldn't be eaten?
Are there other historical examples of bile being deliberately eaten, or any other evidence to suggest bile as good?
Wikipedia says "Bile salts also act as bactericides, destroying many of the microbes that may be present in the food." Perhaps evolution selected for hunters who enjoyed bile on their raw liver because it helped prevent food poisoning? Jeez, it's hard to imagine eating that, no matter how hardcore paleo one wants to be!
Bitters are used to treat problems of the liver and gallbladder. People take bitter herbs, like dandelion root; artichoke(globe) leaves; milkthistle seed; etc... Bitters can help with problems handling sugars as well as digesting fat. Perhaps bile would be the ultimate bitter.
