A healthy human liver contains 575 international units (IU) of vitamin A per gram while a polar bear’s liver contains between 24,000 and 35,000 IU per gram. Compare that to the tolerable upper level of vitamin A intake for a healthy adult human: 10,000. Signs of toxicity generally occur when approximately 25,000 to 33,000 IU are consumed.

Illness severity depended on how much liver the explorers consumed, but symptoms typically included drowsiness, sluggishness, irritability, severe headache, bone pain, blurred vision and vomiting. While milder cases merely involved flaking around the mouth, some accounts reported cases of full-body skin loss. Even the thick skin on the bottoms of a patient’s feet could peel away, leaving the underlying flesh bloody and exposed. The worst cases ended in liver damage, hemorrhage, coma and death.

    Luckily, if you try to eat a polar bear liver, the polar bear will stop you.

    But don’t worry, human liver is safe for polar bears to consume.

    Am I the only one seeing the opportunity regarding billionaires? Of course we have to use a polar bear who is already dead so we don’t have to kill the poor thing to get rid of billionaires. We can start by leaking the rumors that when a polar bear dies due to old age its liver releases certain enzymes that make it extremely delicious. Also eating a spoon of that liver each day for a week has been shown to elongate telomeres and greatly reduce, even revert, aging.

      …greatly reduce, even revert, aging.

      There’s a case to be made that it does stop its consumer from aging much further if applied correctly.

      Having murderous fantasies about people just because they’re wealthy hardly makes you any better person than the ones you despise.

        Not all wealthy people, just insanely wealthy ones, so wealthy that it becomes an act of aggression against all the rest of humanity at that point. Imagine someone hoarding all the water during a drought, that is what these people will be trying to do if there is ever a drought.

    The reason that polar bear liver has toxic levels of vitamin A is that seal liver does and polar bears eat those.

    So don’t eat seal liver either.
