Fallacy of composition. It does not logically follow that given Palmitic acid is the most abundant SFA in the US diet (objectively true), and given the US diet directly leads to poor health outcomes (very likely but not proven at least not to the level of the prior claim), that Palmitic acid contributes to poor health outcomes. It's entirely possible Palmitic acid is great for you and if we had less we'd be doing even worse. The statements are simply not connected at all.

I was replying to someone who was suing the fallacy of composition.

But if you really want to talk about fallacies, why is no one talking about how genetics can determine who these fatty acids are good and bad for? making blanket recommendation for a specific food without knowing someones genetics and heritage is foolish. But do a search for nutritional genetics on HN....nothing.

> > Does Brad Marshall mention that Palmitic acid is the dominant fatty acid in tallow? And since Palmitic acid is the most abundant SFA in the U.S. diet, can we draw a conclusion that it may partially play a role in poor health outcomes?

I don't know the answer to question #1 but the answer to question #2 is "no, we cannot draw that conclusion" because of the fallacy of composition.
