The other problem is that people want a silver bullet. Being told to eat a varied diet with enough macro and micro nutrients is less satisfying than being told that "the thing you want to eat is good and you should cut back on the things you enjoy less".
Or none of the above, like the the failed drugs (other than statins) that reduce LDL and improve the ratio between LDL and HDL, but have 0 effect on heart disease outcomes[0]?

Please investigate the ratio of saturated fats in the food produce you highlighted before making quite coarse statements.
The saturated fat content typically in egg (3% saturated fats) and for example, ground beef with 30% fat content (10% saturated fats) is quite different.
Fat content of industrially produced dairy products can vary quite a lot as well.
So it's quite different thing to eat all of calories for example from butter (50% saturated fat of total weight) or lean ground beef.
