Doesn't saturated fat trigger inflammation? Because if I remember that correctly, then this is a "guns don't kill people, bullets do" argument.
Similarly, doesn't it also cause arterial stiffening? It is not the same process as arterial clogging but definitely makes it worse and is part of heart disease.
Again, I may be misremembering this - I could be confusing fat and meat, for example. Either way it boils down to "eat mostly plants"
