Cholesterol
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.
