Great, now let’s stop pretending that meat dairy and eggs are health foods and that low carb high fat diets are ideal for you, particularly here on the usually-scientific HN. We’ve known of a direct causal link between high saturated fat intake and heart disease for years but this study (published in 2016 by the way) should be the nail in the coffin on the idea that high saturated animal fat is healthy.

In HNs defense, dietary science is a minefield of special interest groups, small sample sizes, animal models and poor controls. Not to mention the editorializing of every p < 0.05 by the media and bloggers, along with all of the n=1 anecdotes. Its so much harder to find valid reliable sources than to find sombody with a book to sell.

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".

What's this supposed direct causal link? Total cholesterol, like we believed before? Or LDL cholesterol, like we believe now?

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]?

Too much saturated fat is a statistical killer in some populations, sure.

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.

Do not forget that many (most?) people here are quite young; in your 20s you can basically eat whatever and not notice it. Let's check people who kept it up for 30+ years. If they exist as I don't think many do anything with diet beyond the fad unless they have something like Crohn's.
