Studies on saturated fat can be confounded by healthy user bias and unhealthy user bias.

“What I would say when it comes to healthy user bias, what you typically see is like no effect of something that should be bad or it'll be inconsistent in the research literature. But it's hard to argue converging lines of evidence. If your if your position is that seed oils are uniquely delterious, it's hard to argue converging lines of evidence when one of the major things you really should see is if people eat more linoleic acid, the effect should be so powerful. If they're the primary driver of cardiovascular disease, which is what some of these people claim, that effect should be powerful enough that even if they were doing other healthy behaviors, that you should still see something and certainly not a protective effect.”
