Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein, or HDL, is known as "good" cholesterol. These two types of lipids, along with triglycerides and Lp(a) cholesterol, make up your total cholesterol count, which can be determined through a blood test. High levels of bad cholesterol can bring on heart disease.
But scientists have mad an interesting discovery about "good cholesterol". Here is a highly scientific article on the helpful properties of "good cholesterol". Scientists have found that good cholesterol is not just good for the heart, it is also good because it can effectively fight cancer cells.
"Good cholesterol” acts as a special delivery vehicle of destruction for cancer by cleansing the body of malignant cells. They found that "synthetic HDL nanoparticles loaded with small interfering RNA selectively shrunk or destroyed ovarian cancer tumors in mice."
This is another great excuse to eat right and monitor your colesterol. Not like Homer Simpson!
