Type of Cholesterol
While most people talk about
"cholesterol levels" there is in fact more than one type of
cholesterol. In fact, there are several different body
functions and several different substances that make up our
understanding of "cholesterol." Type of Cholesterol
information:
As with some fats, cholesterol cannot be dissolved in the
blood. Instead, molecules called lipoproteins carry cholesterol
to and from cells. Molecules are made from an outer layer of
protein and an inner core of both cholesterol and
triglycerides, which is another form of fat.
Lipoproteins equip the cholesterol to move around
the body. The two main types of lipoproteins are:
1) High Density Lipoproteins (HDL.)
- HDL transports cholesterol from cells back to the
liver.
- HDL is either reused or converts to bile acids and
disposed. This is known as "good" cholesterol. You want to
ensure that your levels of this cholesterol remain high for
optimum heart health, since having too low levels of HDL -
even when other cholesterol levels are normal - may lead to
heart problems. As you work to lower your "bad cholesterol"
it is important to also take steps and to keep your HDL
levels normal.
- HDL aids to ensure protection from the risk of heart
attack and/or stroke. HDL consists of more protein than
triglycerides or cholesterol, and aids to remove LDL from
your artery walls.
2) Low Density Lipoproteins (LDL.)
- LDL carries approximately 60-70% of cholesterol around
the body and are known as "bad" cholesterol.
- Studies show conclusively that high cholesterol leads
to much higher risk of heart attack and/or stroke. Other
factors involved in this risk are age, gender, smoking,
family history of heart disease, and diabetes
mellitus.
Obviously, when we speak of having "cholesterol levels" we
mean more than one number. To maintain optimum health, you will
need to know your levels of both LDL and HDL and will need to
work hard to keep both levels in healthy ranges.
