We need some cholesterol. It is an important part of our cells and is involved in the formation of hormones. Since these studies were published, there has been some question concerning the wisdom of low cholesterol diets and particularly of cholesterol lowering medications. But most experts still believe they are necessary since the relationship between elevated cholesterol and heart disease is definite and strong. They point out that heart disease kills more people in the US than any other disease.
High cholesterol is the leading cause of heart disease.
And diets low in saturated fat and cholesterol, exercise, and in some cases medications, can keep an over abundance of this fatty substance from clogging our arteries. Yet, given the uncertainty about the meaning of a low cholesterol level, there's still little reason for those with readings below 160 to worry. On the other hand, those with levels above 200 should consult their doctors about the best ways to get it down.
