Teicholz is considerably snarkier than Willett so, even by that metric, you should lean in favour of Willett’s position that SFA is unhealthy, I guess?
As for my personal position, I remember looking into things a while back and just coming away with the conclusion that nobody really seemed to know. If there's a truth here, it's either considerably more complex than "SFA good" / "SFA bad" (all these interacting pathways, man), or it just makes little enough difference not to matter at all in a way that we can meaningfully measure above the noise.
It seemed clear SFA are clearly not that deadly. Whether you'd be more healthy or live slightly longer if you chose to consume less of them, I have absolutely no clue.
I’m not sure how you’re determining that it’s otherwise?
