What is the meaning of LDL and HDL?
OK so LDL is low density lipoprotein and HDL is high density lipoprotein. LDL is considered to be a bad cholesterol and HDL, a good colesterol.

HDL and LDL are under the five major classes of lipoproteins in the human plasma. role of HDL: transport of cholesterol (as ester) from peripheral tissue to liver for its excretion. HDL serves as a reservoir of apoproteins. role of LDL : supply cholesterol to liver and other extrhepatic tissue for utilisation. transport of cholesterol from liver to tissue for utilisation.
Both HDL and LDL cholesterol are a kind of fat. Since cholesterol cannot be transported into your bloodstream, it needs these two lipoproteins. HDL is also called "good" cholesterol because it tends to wash cholesterol from blood vessels. LDL is called "bad" cholesterol because it can accumulate in your bloodstream when reaches high levels and cause atherosclerosis More details find at http://www.cholesterol-hdl-ldl.com/raise-hdl-cholesterol.html
Sometimes known as "good" cholesterol, HDL Cholesterol is believed to remove other forms of cholesterol such as LDL Cholesterol. HDL is believed to transport LDL to the liver for recycling. HDL is also believed to maintain the walls of the endothelium which is key to reducing the risk of heart attacks and strokes.
LDL: Normal Adult Range: 62 - 130 mg/dl Optimal Adult Reading: 81 mg/dl HDL: Normal Adult Range: 35 - 135 mg/dl Optimal Adult Reading: +85 mg/dl This information was taken from: http://www.drstandley.com/labvalues_lipids.shtml Various things that can affect normal hdl ldl levels. 1- Weight 2- Physical activity 3- Diet strategy 4- Genetic factor 5- Age and sex Source of this info http://www.cholesterol-hdl-ldl.com/hdl-ldl-levels.html
cholesterol Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) are each one of the five major groups of lipoproteins, referring to markers for heart disease. Higher levels of LDL particles promote health problems and cardiovascular disease, they are often called the bad cholesterol particles, (as opposed to HDL particles, which are frequently referred to as good cholesterol or healthy cholesterol particles).
There are two types of Cholesterol that we're concerned with, LDL and HDL. LDL, the bad cholesterol should be minimized and HDL, the GOOD cholesterol should be increased. Diet and exercise are important in controlling TOTAL cholesterol as well as lowering LDL and improving HDL. There is a positive correlation between elevated LDL ratio and buildup of arterial plaque. It also turns out that increasing your HDL correlates with lower arterial plaque; it seems to…
Wallnuts don't contain LDL, by the contrary, they decrease the Low Density Lipid levels, which is known as the bad cholesterol. LDL is produced by the liver when the HDL level is low. It isn't a fat that makes part of any food. LDL level in the blood stream is optimum when below of 100 mg/dl. HDL level is desirable when over 35/40 mg/dl. Wallnuts have many others fantastic medicinal properties.
