Re: Vitamin A.

On the other end of the consumption spectrum:

I remember reading about an Arctic expedition that ran out of food...killed a polar bear for food. Turned out okay for those who ate the muscle meat...not so good for the ones who shared the liver. They died. There is so much vitamin A built up in livers of animals that consume certain fish that their liver is highly toxic to humans.

Yes, too much vitamin A is toxic.

I hear that eating just 1 oz of polar bear liver can kill someone.

This sounds like the Salomon Andree expedition, where Andree and his companions attempted to cross the north pole by hydrogen balloon in 1897. The balloon crash but they survived as was known from surviving photographs they took.

They perished a few weeks later for reasons unknown. One theory to explain their demise was having consumed polar bear liver.
