please note that pouncing on the situation where animal fat costs about 1/4 of what it should realistically cost in the microcosm of the west is one thing ...
suggesting entire planet convert to carnivore is another ...
if the entire planet went keto-carnivore your lard and tallow would cost 10X what they do now !
the other artificially cheap product is LIVER. like lard and tallow it is seem as a by-product when it is actually a superfood.
be careful not to overdose on Liver though - vitamin A is toxic in excess !
