Cholesterol
Cholesterol is a soft, fat-like, waxy lipid
attached to a protein (called a lipoprotein)
found in the bloodstream and in all your
body's cells. It is an important part of having a
healthy body because it's used for producing
cell membranes and some hormones, insulating
nerves, and it also helps many bodily functions.
All lipoproteins are classified into different
groups such as high density, low density, and
very low density depending on their ratio of fat
to protein.
Cholesterol
Having too much
cholesterol in your
blood is a major risk
for coronary heart
disease. This is a
disease which leads to
a heart attack.
Hypercholesterolemia
is the medical term
for high levels of
blood cholesterol.
Cholesterol
There are two main
different types of
Cholesterol:
 HDL
(Good Cholesterol)
 LDL
(Bad Cholesterol)
HDL (Good) Cholesterol
HDL cholesterol, also known as good
cholesterol, is a high density lipoprotein
(HDL) that carries bad cholesterol away
from the arteries. These lipoproteins carry
about ¼ to 1/3 of blood cholesterol. By
having a high level of HDL, you can
reduce your risk of having a heart attack or
a stroke.
LDL (Bad) Cholesterol
LDL cholesterol, also known as bad cholesterol,
is a low density lipoprotein (LDL) that
circulates in the blood stream. When you have
too much LDL, it can slowly build up in the
inner walls of the arteries. By building on the
walls, the arteries are narrowed and it puts
strain on the heart and lungs as the blood
circulates. The medical condition for having
narrowed arteries is called atherosclerosis. If an
artery becomes completely blocked, it causes
you to have a heart attack or stroke.

Very Low Density Cholesterol
Very low density lipoproteins, also called
VLDL, are much like LDL cholesterol, but
contain mostly fat rather than protein.
These lipoproteins are highly dangerous
and need medical treatment to help lower
the count.
Triglycerides
Triglycerides are another type of fat which
is carried in the blood by very low density
lipoproteins. Triglycerides are converted
from excess calories we obtain from foods
and liquids, such as alcohol or sugar and
stored in fat cells throughout the body.
Where does it come from?
Cholesterol comes from two sources:
 your body
 food
Your liver and other cells in your body make around 75 percent of
blood cholesterol. The other 25 percent comes from the foods you
eat.
LDL cholesterol is produced naturally by the body, but many people
inherit genes that cause them to make too much.
Eating saturated fat, trans fats and dietary cholesterol also increases
your cholesterol level. Trans Fats are especially dangerous and are
found in many packaged foods, such as chips and canned goods.
Trans fat lowers your good cholesterol level and raises your bad
cholesterol.
Diseases and Health Problems
Many diseases and health problems can arise
from high cholesterol such as:
 High blood pressure
 Diabetes
 Coronary Heart Disease
 Coronary Artery Disease
 Stroke
 Heart Attack
Lower Your Cholesterol
You may eat up to 30% of total fat, but eat mostly
unsaturated fat because it does not raise your
cholesterol levels.
Eat foods such as:



Whole wheat bread
Brown or wild rice
Fruits without added sugar
Vegetables with low-salt and no cream or cheese
Fat-free or 1% milk
Lean cuts of meat
Fish
Did you know???
 105 million Americans have total cholesterol of
200 mg or higher. It is this level at which
cardiovascular risk begins to rise.
By watching how
we eat and have
up to date health
exams and blood
tests for our
cholesterol, we
can reduce this
number greatly.
