What is cardiovascular disease? If we dig into that we find things like atherosclerosis and other types of diseases. Something like atherosclerosis happens, in large part due to LDL cholesterol [1]. There are many studies and papers on it. Scientists know a fair amount about what's going on here.
Saturated Fat is a leading cause of high LDL cholesterol [2]. Dietary cholesterol plays a role in elevated cholesterol but to a lesser extent. A way to think about it is that animals (including humans) produce the LDL cholesterol they need. Cows, pigs, and other animals do too. When you eat them you eat extra LDL cholesterol that ends up in your system.
I just grabbed a couple quick links on the topic. There are many podcasts with cardiologists on this, books by dietitians, and papers by researchers.
On a personal note, I had high cholesterol and cut out dietary cholesterol and saturated fats (to the level recommended by the american heart association [3]). In a few months my LDL cholesterol dropped about 70 points. I know it's anecdotal but it worked for me and several others I know.

- dnissley 4y agoAren't there certain cultures with high saturated fat intake but very low occurrence of heart disease? E.g. Inuits
- mfer 4y agoThe data on their life expectancy shows it was far lower than average. What caused this? Was it heart disease? Infant mortality? Something else? Did they live long enough on average to get heart disease? The inuits eat more of a western diet now so getting data on their traditional diet must be difficult. In any case, we don't have enough data to justify them as a data point supporting high saturated fat diets.
- dnissley 4y agoWhat data are you looking at? Consider also the Minnesota Coronary Experiment which violates this connection: https://www.scientificamerican.com/article/records-found-in-dusty-basement-undermine-decades-of-dietary-advice/ https://www.scientificamerican.com/article/records-found-in-...

- dnissley 4y agoYeah this is my understanding as well. Dietary cholesterol only weakly correlates with blood cholesterol
- boringg 4y agoCholesterol is not as well understood as is believed.
