HDL stands for "High Density Lipoprotein" and it is a combination of fat lipids, and proteins, the form in which lipids are transported in the blood. HDL transports cholesterol from tissues to the liver.
LDL stands for "Low Density Lipoprotein" they are combinations of fat lipids and proteins. LDL transports cholesterol to the
The function of LDL is to deliver cholesterol to the cells, where it is used in membranes or the synthesis of steroid hormones.
HDL are protective particles, they protect against heart disease because of the transport of excess cholesterol out of the body.
Why doctors track HDL and LDL
They do blood tests, they can measure total cholesterol levels and they can split it up to HDL and LDL. They do these tests because if there is to much cholesterol in the blood plaques can start to form, causing hardened arteries and eventually heart attacks and strokes.
LDL and HDL association with risk for heart disease
If you have low HDL levels then you might be at risk for heart disease. If you have low HDL then you might also be diagnosed with type 2 diabetes. Smoking and being overweight could lead to low HDL levels.
If you have high LDL levels then you might be at risk for heart disease. High LDL levels could lead to heart attack and stroke,eating foods high in saturated and trans fats raise LDL levels.
Monitored along with LDL and HDL
Other things that are monitored in the blood along with LDL and HDL is the cholesterol and the triglycerides. The cholesterol travels through the blood attached to LDL and HDL. Triglycerides are a type of fat in the body used to give energy to the muscles, only small amounts are found in the blood but if there is too much you may be at risk for heart disease.
What do results of cholesterol tests mean?
Cholesterol levels are measured in milligrams per deciliter, below 200 mg/dL
200-239 mg/dL is borderline high
240 mg/dL and above is high
What to do to change LDL and HDL levels
Ways to lower your LDL levels are to lessen the in take of butter, red fleshy meats, full fat and low fat dairy products, palm and coconut oil.
Ways to increase HDL levels include getting active, loosing weight, eat healthier, drink little to no alcohol, and stop smoking.
Saturated, unsaturated, and trans fats
If you eat to many trans and saturated fats, you could be at risk for certain diseases such as heart disease.
Fats like monounsaturated and polyunsaturated fats are good for the heart and the body.
