The body contains the lipids HDL and LDL, which are proteins that carry the cholesterol molecule. HDL is the “good” cholesterol, while LDL is the “bad." It is healthier for the body to have elevated levels of HDL and low levels of LDL.
HDL
High-density lipoprotein (HDL), the "good" cholesterol, carries about one-third to one-fourth of the cholesterol found in the bloodstream. The American Heart Association indicates that many medical experts believe that HDL actually carries cholesterol away from arteries to the liver, reducing plaque buildup in the arteries.
LDL
Low-density lipoprotein (LDL) carries cholesterol to the arteries, where it can buildup and form plaque. Too much arterial plaque may result in blockages that can lead to heart disease.
Desired HDL Levels
According to the American Heart Association, HDL levels that are below 40 milligrams/deciliter may put a person at a higher risk for heart disease. They recommend a level of 60 milligrams/deciliter or higher to help maintain heart health.
Desired LDL Levels
High LDL levels may be dangerous to the heart. LDL levels should be lower than 100 milligrams/deciliter for optimal health. Anything greater than 150 milligrams/deciliter is too high.
Lower LDL Levels
It is possible to lower your LDL level to some extent. The American Dietetic Association (ADA) recommends eating a diet low in saturated fat and high in fiber. They suggest maintaining a healthy weight and being physically active on a regular basis.
