VLDL cholesterol, or very low-density lipoprotein cholesterol, is a type of lipid particle in the blood that is often associated with cardiovascular disease risk. In the context of longevity, monitoring and managing VLDL cholesterol levels is important as it is a key biomarker for assessing heart health and overall longevity. High levels of VLDL cholesterol are linked to an increased risk of atherosclerosis, heart attack, and stroke, all of which can significantly impact life expectancy. By keeping VLDL cholesterol levels within a healthy range through lifestyle modifications and, if necessary, medication, individuals can help promote their longevity and reduce the risk of cardiovascular disease.
