"All the research" and "nothing to do with" are both huge oversimplifications / exaggerations of what otherwise might be a good point.
"A summary of the committee’s December 2014 meeting says “Cholesterol is not considered a nutrient of concern for overconsumption.” Translation: You don’t need to worry about cholesterol in your food.

> A better focus is on reducing saturated fat and trans fat in the diet, which play greater roles in damaging blood vessels than dietary cholesterol.
