HDL Cholesterol
HDL cholesterol is the so-called "good cholesterol" you've probably heard about. But you may not understand why
it's considered good cholesterol.
As explained in our article on HDL and LDL cholesterol, there are two main kinds of "lipoproteins" or types of fat in the
bloodstream.
Now, when you hear the words "fat in the bloodstream," you naturally tend to think, "That can't be good."
But actually, HDL, or high density lipoprotein, is good because it helps keep your heart healthy and your blood
vessels clear and open.
To understand why you want to have a healthy amount of HDL, you need to understand a bit about the other type of
cholesterol: LDL. It's generally known as "bad" cholesterol, and there's a reason.
LDL cholesterol (LDL stands for low density lipoproteins) is the stuff that sticks to artery walls, forming a
substance called plaque.
This plaque and clogs up your circulatory system. Your organs and tissues don't get all the oxygen and nutrients
they need to function at top efficiency.
Plus, when plaque narrows your blood vessels, your heart has to work harder to pump blood all over your body.
This condition is known as high blood pressure, or hypertension. High blood pressure places additional workload on
your heart, which eventually wears the heart down.
A cardiologist we know refers to HDL cholesterol as the "scrubbing bubbles" of the bloodstream. HDL attracts bad
fats that are in the system and sweeps them away. They're eventually flushed out of the system before they can
cause trouble.
That's one of the reasons doctors are always telling you to get some quality exercise. When you raise your heart
rate, it forces your HDL into contact with your LDL. As a result, your LDL gets cleared out and your doctor is very
happy next time he or she looks at your cholesterol levels.
It's also important to remember that certain foods contain a lot of LDL, and other foods contain a lot of HDL.
The more you focus on HDL foods in your diet, the healthier you will be.
High HDL content foods include fruits, vegetables, certain kinds of nuts, and grains. Olive Oil and Canola Oil
contain a lot of monounsaturated fatty acids, which raise your HDL level. Omega 3 fatty acids, like those found in salmon, are high on the list of
HDL-friendly foods.
You've probably heard plenty in recent years about all the foods that contain a lot of bad cholesterol. Beef,
pork and poultry put more LDL into your system, although pork and poultry have less than beef.
Convenience foods, which are usually highly processed, and fast foods (especially fried fast foods) generally
increase the level of bad cholesterol and should be avoided. This is a tough recommendation to follow in this day
and age, but it's important.

cholesterol. To read them, click on cholesterol free foods, cholesterol lowering foods, how to increase your HDL, and how to lower your LDL.
