My local bison farmer (grass-fed and organic, of course!) sells the organ meats at rock bottom prices. I want to know if there are any dangers of eating too much liver or heart.
Michael Eades discusses the zinc-copper ratio, saying we generally don't get enough copper (comes from liver), but are there dangers of getting too much from eating liver?
What makes me a bit worried about eating a lot of organ meat is that hunter-gatherers would have eaten the whole animal and gotten a balanced mix of muscle and organ meats. (On the other hand, insofar as liver was considered a delicacy, the tribe leaders might have had first dibs on it and eaten quite a bit.)
