Why Most Doctors are Wrong About CholesterolCholesterol is a waxy substance found in nearly every cell of your body and is essential to good health. It plays a role in hormone production, digestion and the manufacture of vitamin D following sun exposure, and helps protect your cell membranes. As noted by Zoe Harcombe, Ph.D., "It is virtually impossible to explain how vital cholesterol is to the human body. If you had no cholesterol in your body you would be dead." Cholesterol has long been vilified as a primary cause of cardiovascular disease (CVD), yet numerous studies refute this hypothesis, demonstrating that cholesterol has virtually nothing to do with heart disease — at least not in the way conventional medicine presents it. As noted by Harcombe, the notion that there is good and bad cholesterol is also wrong. Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) are not actually cholesterol; they're carriers and transporters of cholesterol, triglycerides (fat), phospholipids and proteins. "LDL would more accurately be called the carrier of fresh cholesterol and HDL would more accurately be called the carrier of recycled cholesterol," she says. What's more, dietary cholesterol has no impact on the cholesterol level in your blood, so how could dietary cholesterol pose a health risk?
