It can be worse than that! The livers of canivores tend to be enriched in Vitamin A, which sounds fine except that Vit. A is more poisonous than cyanide taken chronically. Certainly hunting people who have canivores as part of their diet (usually bears) avoid eating the liver. There is sufficient Vit. A in polar bear liver for a few grams to be fatal.
Apocraphyl: Some whalers were supposed to have shot and consumed a polar bear. Those individuals unwisely partaking of the liver had such an increase in intra-cranial pressure, their heads split open.
Heads splitting open from eating polar bear liver? Do you have a cite for that?
Head splitting aside, is the 20 year old answer still valid? Is there any effect of using growth hormones on cattle that they grow up faster and have less time to collect trace metals in their livers?
And what about eating liver acting as an enabler for people to consume mass quantities of genetically modified onions or tomatoes in ketchup?
It doesn’t create enough pressure to cause the skull bones to actually split, because long before it would build up enough pressure to crack the bones, it would bulge out–herniate–out through the back of your skull. And you’d be dead.
Which isn’t quite the same thing as “their heads split open”. But it’s pretty close.
By the way, my brain is herniated through the foramen magnum. The lower tip of my brain is down all the way to the space between my second and third vertebrae (C2 and C3). However, I was born this way, so it didn’t happen suddenly. I tell everyone that it’s because my brain is just too large for my skull (which is XXL anyway).
Because so-called cooks (Hi! Mom.) don’t know how to cook liver. They choose the cheapest kind and cook it well-done, ensuring that the final product causes the eater to immediately wonder if his sneakers are still in his closet.
