Cholesterol Info
As you lower your cholesterol, you will likely encounter new
words and terms. As you get used to these new concepts, feel
free to turn to this glossary of cholesterol info to help you
recall what is what:
Atherosclerosis
If you have too much cholesterol in the blood, it will
create a yellow thick substance on the lining of the blood
vessels. This is known as atherosclerosis. If it continues to
grow, it can block blood vessels, leading to a stroke or heart
attack. This is a key risk of having high bad cholesterol
levels.
Blood Cholesterol
Blood cholesterol is wax-like material that is made by the
body. Blood cholesterol is needed to keep cells healthy, to
create hormones, and to keep the body functioning. Too much,
though, increases your risk of atherosclerosis.
Dietary Cholesterol
Dietary cholesterol is the cholesterol found in some of your
food. Since all animals produce cholesterol, dietary
cholesterol is found in the foods that are made from animals
(foods such as meat, dairy products, fish, and eggs). To stay
heart-healthy, you will want to avoid eating too much dietary
cholesterol.
Cholesterol Profile
Your cholesterol profile is a listing of your cholesterol
levels. This includes your LDL, HDL, your total cholesterol,
and triglycerides. Your doctor finds this information through a
blood test. Your cholesterol profile helps medical
professionals determine how much at risk you are for developing
certain complications associated with high bad cholesterol
levels
Essential Fatty Acids
Your body needs fats to survive, and especially to build
cells. The fats your body needs to get from the foods you eat
are called essential fatty acids.
Fiber
Fiber is the part of plants that cannot be digested by us.
There are two types of fiber: insoluble and soluble. Both are
important to health. Insoluble fiber in grains and fruits and
vegetables is what keeps you "regular" and keeps your bowels in
good shape. The soluble fiber found in oats, barley, and other
plants has been found to lower cholesterol levels. If you are
trying to lower your cholesterol and stay healthy, eating a
diet with adequate fiber can help.
High Density Lipoproteins (HDL)
This is known as the "good" cholesterol, and is generated by
the liver. HDL transports cholesterol and fats to your liver
from your arteries. In the liver, the fats can be broken down
or recycled for your body to use. If you have high levels of
HDL, chances are your heart is healthy, since the cholesterol
is being effectively transported rather than being left in your
blood, where it can cause a hardening of the arteries. If you
have too low levels of HDL, you may be putting your heart at
risk.
Hydrogenated Fats
These are fats you want to avoid in your diet if you want to
lower bad cholesterol levels. Hydrogenated fats are fats -
either polyunsaturated or monounsaturated - that have been
treated with hydrogen atoms to guarantee a longer shelf life.
The process of hydrogenation causes fats to become saturated
fats.
Lipid Specialists
These doctors specialize in the treatment of treating high
blood cholesterol and related health issues. If you have very
high cholesterol and traditional methods of lowering your
cholesterol and risk for heart disease do not work, you may be
referred to a lipid specialist for specialized treatment.
Low Density Lipoproteins (LDL)
Also called "bad cholesterol", LDLs is manufactured by the
liver. Its job it to transport fats - including cholesterol -
from the liver to the areas of your body that need the fats
(such as your organs, muscles, and your tissues). If your LDL
levels are high, it suggests that there is plenty of
cholesterol in your blood, which increases the chances of
clogged arteries, which in turn in very dangerous for your
heart.
Monounsaturated Fats
These fats are liquids at room temperature. These fats are
also good for you because they don’t change your HDL (good
cholesterol) levels but do lower your LDL (bad cholesterol
levels). Look for products that have these fats if you want to
stay heart-healthy. Monosaturated fats are found in olive and
canola oil.
Omega_6
This is actually a "family" of fatty acids that increase
your good cholesterol level while lowering your bad
cholesterol. This makes Omega-6 a great food source for staying
healthy. You can find these fatty acids in nuts, grains,
vegetables, and vegetable oils. They are part of the reason why
you are likely encouraged to eat these foods in your
low-cholesterol diet.
Polyunsaturated Fats
These fats are liquid at room temperature. They are a better
choice than saturated fats, but they tend to lower both good
and bad cholesterol levels, so they are not the best choice for
good health. In small amounts, these fats may lower bad
cholesterol.
Processed Foods
Processed foods are foods that have been treated before
being sold. In some cases, processed foods are treated to
eliminate bacteria or make foods healthier. For example, the
process of pasteurization eliminates some of the harmful
elements in milk that can make us sick. Most of our foods are
processed in some way. However, some foods are processed in
order to change their taste or in order to give them a longer
shelf-life. The processing that it takes to do this sometimes
involves adding fats, salts and other unhealthy ingredients or
involves heating the foods until some or much of the nutrient
value is lost. When choosing processed foods, it is important
to choose foods that have as few detrimental ingredients as
possible. In general, foods that have had more done to them
(such as deli meats, potato chips, cookies, and others) and
foods that are considered "fast foods" or convenience foods
(such as hamburgers, prepared hors d’oeuvres, and cocktail
snacks, among others) are higher in fats and salt. Read the
labels of all processed foods to understand exactly what you
are eating and how these foods may affect your health.
Saturated Fats
These fats are solid at room temperature. They are also the
most likely to raise your bad cholesterol - in fact, they are a
bigger culprit than dietary cholesterol. If you want to lower
your cholesterol, avoid these fats in your food. In many cases,
saturated fats come from animal proteins and products (meats,
and milk products). They are also found in hydrogenated
vegetable oil and in coconut and palm oil.
Trans-Fatty Acids
These are another fat group you will want to avoid. They are
hydrogenated and increase bad cholesterol while lowering good
cholesterol.
Triglycerides
Triglycerides are a fat - like cholesterol - which is
transported in the blood stream. This fat is the culprit behind
most of the fat in the body. Like LDL-cholesterol, it can form
a thick goo and block arteries if there is too much of it in
the blood. As you lower your bad cholesterol, you will also
want to keep your triglycerides low. Often, high triglycerides
are caused by too much alcohol use, overeating (or being
overweight) and not enough physical exercise.
Very Low Density Lipoproteins (VLDL)
These lipoproteins transport cholesterol from the liver to
the body organs and tissues that need it. Studies have shown
that high levels of these lipoproteins may be a risk factor for
heart disease. Not all cholesterol profiles include a number
for VLDLs, but if yours does, work to keep the levels low.
