If you are stranded in the Arctic and happen to have access to a polar bear for your lunch, think twice about eating the liver. Polar bear livers are extremely high in Vitamin A, cadmium, arsenic, and a host of other toxic substances. Your little polar bear liver snack will likely result in hair loss, extreme flakey skin, headaches, abdominal pain, diarrhea, dizziness, etc. If you are already in a weakened condition, that polar bear liver may well be your last meal.
Oh… and it’s not all that healthy for the bear, either.
