Was primitive man Statin deficient?
Of course not, any more than he was blood pressure medicine deficient, Or diabetes insulin kit shot deficient. If you have, say, high blood pressure, the question to ask is why in the hell do I have high blood pressure? What kind of garbage am I eating that is increasing my blood pressure. Not; why am I Losartan deficient. Can you imagine paleolithic man walking around poking his finger every hour to check his blood sugar? Then injecting himself with drug company insulin? Medical science; in cohorts with the mega food companies are just cracked.
If a paleolithic kid had type 1 diabetes he wouldn't inject insulin he'd just die on a rock somewhere and get eaten by a bear.
Paleolithic man most likely had statins in the form of intestinal parasites.
