Lard Retraction!
Folks, I have to apologize. It appears I was wrong about the high vitamin D content of lard. An astute reader pointed out to me that my reference for that was not very solid. Upon double checking it, I found that he was right. Lard from pasture-raised pigs (and tallow from pasture-raised cows) has about as much vitamin D as summer butter, which is enough to prevent rickets but not enough to make a major contribution to an optimum intake. So while pasture-raised leaf lard is still on my list of good fats, please don't rely on it to provide vitamin D. I'll be correcting my earlier posts. Sorry for the mistake.
