The primary marker of a healthy blood lipid profile is a desirable level of low-density lipoprotein (LDL) cholesterol, commonly referred to as "bad cholesterol." Lower LDL levels reduce the risk of atherosclerosis and heart disease. Conversely, higher levels of high-density lipoprotein (HDL) cholesterol, known as "good cholesterol," are beneficial as they help remove LDL from the bloodstream. Regular monitoring of these markers is vital for maintaining cardiovascular health and ensuring a balanced lipid profile that supports overall well-being.
