We've known about cholesterol and cardiovascular risks and how to reduce them for decades. The problem isn't access to information, it's false information creating incorrect or purposefully conflicting narratives which confuse and debase science.
Dietary cholesterol is actually pretty weakly correlated with cardiovascular disease, and yet people have significantly changed their behaviors (for the worse, most likely) in the years since this mistaken science proliferated - the infamous replacement of high-fat diets with high-sugar ones.
You're working on old research. All newer research points to no correlation. Even worse, all attempts to reduce CVD by reducing blood cholesterol have completely failed as well, in several large scale clinically controlled trials.
> For years, dietary cholesterol was implicated in increasing blood cholesterol levels leading to the elevated risk of CVD. To date, extensive research did not show evidence to support a role of dietary cholesterol in the development of CVD.
