Cholesterol is a fatty substance that occurs naturally in the blood, cell walls, and most body tissues. Cholesterol is made by the liver, and it enters the body via foods rich in saturated fat.

There are two types of cholesterol; these are what they termed as the good and bad cholesterol.

Low Density Lipoprotein (LDL) is the "bad" cholesterol. This is the form in which cholesterol is carried into the blood and is the main cause of harmful fatty buildup in arteries. The higher the LDL cholesterol levels in the blood, the greater the heart disease risk.

On the other hand, High Density Lipoprotein (HDL) is the “good” cholesterol. This "good" cholesterol carries blood cholesterol back to the liver, where it can be eliminated. HDL helps prevent a cholesterol buildup in blood vessels. Low HDL levels increase heart disease risk.

Cholesterol is essential for human life. It builds and repairs cells, it is used to produce sex hormones like estrogen and testosterone, it is converted to bile acids to help you digest food and it is found in large amounts in brain and nerve tissue.
