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.”
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.
