i have, although i don't make it a habit, cause then your broth kinda sucks without it! but i've extensively dry rendered chicken fat. i'm jewish, we do that. not the healthiest animal fat, but in my defense, it was from a pastured chicken. and the cracklins ('gribbenitz' in yiddish) are so ridiculously good, it's ridiculous.
"dean ornish and dr. davis think the palmitic acid our bodies use for fuel while we sleep is poison if we eat it. zero-carbers like charles washington think the oldest fuel in our evolutionary history – glucose - used by organisms a billion years ago and without which the brains of modern mammals cannot survive for more than a few minutes – is an unnatural toxin if you eat it. both views ignore basic facts of medical physiology and defy evolutionary history." - kurt harris
