Cholesterol is a waxy substance that is needed for a healthy body. The cholesterol molecule is actually carried through the blood by the lipoproteins HDL and LDL. HDL is the "good" cholesterol, while LDL is the "bad" type.
Good Cholesterol
HDL, or high-density lipoprotein, is responsible for carrying about 25 to 30 percent of the cholesterol in the blood. The American Heart Association states that HDL brings cholesterol back to the liver when it can be taken out of the bloodstream, helping remove plaque buildup.
Bad Cholesterol
LDL, or low-density lipoprotein, carries cholesterol molecules to the arteries. Too much of this "bad" cholesterol can result in heart disease due to artery blockages
Elevated HDL Levels
It is desirable to have high HDL levels. The American Heart Association recommends a level of 60 mg/dL to help protect the heart. They state that levels lower than 40 mg/dL may actually put a person at risk for heart disease.
Elevated LDL Levels
LDL levels should be kept at a low level. Levels that are 150 mg/dL or higher are considered to be dangerous. The American Heart Association recommends a level of less than 100 mg/dL for heart health.
Monitor Levels
A physician should monitor cholesterol levels. The American Dietetic Association recommends an active lifestyle and healthy diet low in cholesterol and high in fiber to keep LDL levels low.
