Why does the body make and recycle cholesterol if it is so bad li ke doctors say?

Necessary chemical: Cholesterol is an essential chemical and is an integral component of every cell in your body. The physiology of cholesterol balance (homeostasis) involves exogenous cholesterol (diet) and endogenous cholesterol (manufactured in liver). What your body does with this balance and how cholesterol is packaged and used determines the amount of vascular irritation that results.

Cholesterol is vital: Before people ate a lot of animal fat (thousands of years ago), the body had to conserve cholesterol, which is used for vital functions like making hormones and cell membranes. So the body has a system to reabsorb cholesterol and conserve it, because in the old days, we ate hardly any cholesterol.
