The study in question is not out yet, but there are leaks that suggest that a major new approach to cholesterol will be contained in its pages. The most important aspect? This:
More recent research shows that consuming cholesterol does not actually seem to have much, if any, impact on the amount of cholesterol found in the blood.So, yeah. It's mostly genetic. And we need to be far more concerned about the types of fats we consume (saturated, trans, whatever), how many calories we consume, and how much exercise we get than we do about cholesterol. Who knew?This is part of a broader shift away from the idea of a tight connection between diet and cholesterol levels in the bloodstream. Your genes, as it turns out, are a much bigger factor in determining whether you'll have lots of cholesterol in your bloodstream."Basically, our bodies make a lot of cholesterol," Willett said. "So, really, we are our own most important source of cholesterol." Cholesterol is a key building block of many essential hormones, including sex hormones, and dietary cholesterol doesn't appear to affect those functions, either.
