““Dr. Bowden: Let’s go back in time. If you went to a health fair around 1950, you’d see people sitting there with little pin pricks on their fingers that were used test your blood for cholesterol. The nurse would say, "Oh, Mr. Jones, your cholesterol is 175." She would give you just one number. In the early 1960’s, researchers realized that cholesterol travelled in the body in two distinct packages. One of them is called HDL or high density lipoprotein. The other one is called LDL or low density lipoprotein. They discovered that LDL and HDL functioned and behaved somewhat differently in the body, and we began to nickname HDL "good cholesterol" and LDL "bad cholesterol." ””
