Humans clear LDL from the blood much less efficiently than almost any other mammalian species, resulting in higher baseline circulating blood LDL levels.
"we don't have a very efficient way of removing LDL from the blood, so our levels are much higher than almost any other species, certainly most other mammals. You have to feed an enormous amount of cholesterol in order to get anything like what we have in our blood." (said at 0:09:43)
No published record matching the comparative clearance rate of low-density lipoprotein (LDL) in humans versus other mammalian species was located; this does not prove the claim false.
