What is the difference between HDL and LDL cholesterol levels in the body?

HDL (high-density lipoprotein) cholesterol is considered "good" cholesterol because it helps remove LDL (low-density lipoprotein) cholesterol from the bloodstream. LDL cholesterol is considered "bad" cholesterol because it can build up in the arteries and increase the risk of Heart disease. Maintaining a balance between HDL and LDL levels is important for heart health.
