He could have stores in his liver tho for that entire time. How do we know genereux is actually retinol deficient?You have posted a summary of the mainstream position on "Vitamin A".
Genereux has refuted this by living without vitamin A for almost 10 years now and not losing his eyesight. If there's only one black swan, the claim that "All swans are white" is debunked. If there's only one person who can go without vitamin A, the claim that vitamin A is essential for humans is debunked.
The argument that sometimes comes up - he still eats miniscule amounts of retinol and therefore that small amount goes to the eyes to save him - is ridiculous. That would mean that something like 10mcg of retinol per day would be enough, which is basically the same as saying it's not essential.
Whether few molecules of retinol are actually essential is a matter that is independent from the toxicity epidemic. Lowering retinol as much as possible is still the answer for most people, even if extremely small amounts are necessary. The liver stores need to be emptied.
Something that is as toxic as retinol is likely not essential, it's just a toxin, no matter the dose.
Carnivores have a higher ratio of hepatic stellate cells to hepatocytes. The stellate cells store retinol. the hepatocytes are the normal liver cells that are responsible for the usual processes in the liver. That doesn't mean they thrive on retinol, it just means they can get away with eating other animals.
Carnivores are also able to excrete retinyl esters through the urine, something humans can't do. This means that carnivores detoxify the dangerous unbound form of retinol conveniently via urine, while in humans elevated free retinyl esters are very dangerous and can build up easily.
These differences between carnivores and humans is the primary reason lions can get away with eating liver. This also shows that humans were never designed to eat high A foods like liver, otherwise we would be able to excrete retinol via urine.
