But the truth is that when you talk about dietary cholesterol and blood cholesterol you are really talking about two different things, and the connection between them is neither direct nor entirely clear. In fact, what one has to do with the other has been a topic of contention in the nutrition world for decades.
And chances are, if you’re worried about how much cholesterol you’re getting from your diet, you probably don’t need to be. So before you order another egg-white omelet, read this.
Dietary cholesterol isn’t really the culprit that raises your cholesterol levels.
It would make sense that eating cholesterol would necessarily raise your blood cholesterol level, which in turn raises your risk for heart disease. But that’s not really how it works.
First of all, your body requires cholesterol for necessary functions like hormone production and digestion. What’s more, your body makes all the cholesterol it needs, producing most of it in the liver and sending it into the bloodstream to get used elsewhere. Therefore, whether you have high or low cholesterol is largely determined by your genetics, not your diet.
