LDL, low-density lipoprotein, is a type of cholesterol. Too much of it can lead to build up in arteries. The build can clog the blood flow, leading to a depletion of of oxygen to tissues around the body. HDL, high-density lipoprotein, carries cholesterol from other parts of your body back to the liver.

What can patients do to change the levels of LDL and HDL in their blood?

# data[].attributes.body
A patient can decrease their LDL and HDL levels in their blood by: stopping smoking, exercising, drinking alcohol only in moderation and having good diet. Reducing saturated fats, eliminating trans fat, eating foods rich in omega-3 fatty acids, increasing soluble fibers and adding whey protein.

 Why do doctors monitor the concentrations of LDL and HDL in patients’ blood?

# data[].attributes.body
Doctors monitor the concentrations of LDL and HDL levels in a patient's blood because if there is too much cholesterol in the blood it could affect the blood flow, decrease oxygen flow and cause angina. This is not healthy for the patient.

What do the results of a cholesterol test mean? How do patients interpret each value?

# data[].attributes.body
The results of a cholesterol test can show high or low cholesterol levels. Less than 200 mg/dL is considered a good blood cholesterol. Greater than 240 mg/dL is considered a high blood cholesterol concentration. Too much cholesterol leads to complications regarding the heart and blood flow.

How do LDL and HDL differ structurally and functionally?

# data[].attributes.subject
How do LDL and HDL differ structurally and functionally?

# data[].attributes.body
LDL and HDL differ structurally because LDL has the potential to build plaque in arteries. Furthermore, HDL takes cholesterol back to the liver. The composition are the greatest structurally difference. In LDL, only 25 percent is made up protein and 50 percent is cholesterol. In contrast, HDL 50 percent is made of protein and 20 percent is cholesterol.

How are the concentrations of LDL and HDL associated with the risk for heart disease and associated disorders?

# data[].attributes.body
The concentrations of LDL and HDL are associated with the risks for heart disease and disorders because high cholesterol clogs arteries. This causes the heart to have work harder and ultimately lead to disease and disorders.

How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health?

# data[].attributes.subject
How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health?

# data[].attributes.body
The intake of saturated fats and trans fats significantly increase the amount of cholesterol in the blood. Both monounsaturated and polyunsaturated fats lower LDL levels. Monounsaturated fats maintain or raise the HDL levels, whereas polyunsaturated fats lower the HDL levels.
