What is LDL,HDL ?

Cholesterol is a waxy fat that is present in all human beings. About 80 percent of the cholesterol in the body is manufactured by the liver. The rest is consumed through cholesterol-rich foods such as meat, eggs and dairy products. Cholesterol is carried through the bloodstream by proteins called apolipoproteins. When these proteins wrap around cholesterol and other types of fats (lipids), the resulting 鈥減ackages鈥?are called lipoproteins. There are five types of lipoproteins: High-density lipoproteins (HDL), which are associated with 鈥済ood鈥?cholesterol. Low-density lipoproteins (LDL), which are associated with 鈥渂ad鈥?cholesterol. Very-low-density lipoproteins (VLDL), which are associated with "very bad" cholesterol. Intermediate-density lipoproteins. Like VLDLs, these also carry triglycerides and cholesterol. Chylomicrons, which carry only a small percentage of cholesterol. Chylomicrons are mostly rich in another type of fat called triglycerides. Total cholesterol levels less than 200 are desirable. Total cholesterol levels between 200 and 239 are borderline-high. Total cholesterol levels that are 240 or higher are high. HDL levels of less than 40 for men and 50 for women are considered low, and levels of 60 or more are considered protective against heart disease. HDL levels should be 40 or above (the American College of Cardiology recommends levels of 45 or above for women. LDL levels should optimally be less than 100 (levels greater than 129 are considered borderline-high, and levels greater than 159 are considered high). These are the basic details.

Hi mom, LDL and HDL are good and bad cholesterol. Here is a site that explains it all.

http://en.wikipedia.org/wiki/Cholesterol

Low Density Lipoprotein
High Density Lipoprotein

Types of cholesterol.

low density and high density lipids. they are two tests that the docotrs run on you along with triglyerides and cholesterol to help in diagnosing wether or not you are at risk for high cholesterol. hope this helps.

LDL = bad cholesterol
HDL = good cholesterol

ldl is bad as it carries cholesterol away from the liver to be utilized or deposited in arteries,whereas hdl is good as it collects cholesterol from peripheries to be utilized by liver in manufacturing bile.

one way to remember LDL and HDL are:

LDL ==lethal
HDL ==Healthy

easy to remember

As most people have said, good & bad cholesterol.

Ignore the poster who cites one or two people's interpretation of studies. Who are you going to believe, rogue "scientists" or the world medical community?
