You ever wonder why humans are the only animal that gets atherosclerosis?
It's because in our evolution we lost the gene to synthesize Neu5Gc, something that almost every mammal on earth does
So if we actually consume Neu5Gc particularly from red meat or dairy, our body will create anti-bodies against it and it will cause vascular inflammation amongst other problems which could lead to atherosclerosis

Don't eat red meat or dairy, eat chicken and fish instead
