Cholesterol is a waxy, fat-like substance found in all cells of the body, necessary for making hormones, vitamin D, and substances that help digest foods. The body produces cholesterol, but it is also obtained from animal-based foods. Cholesterol travels in the blood in packages called lipoproteins, which include low-density lipoprotein (LDL, or “bad” cholesterol) and high-density lipoprotein (HDL, or “good” cholesterol). High levels of LDL cholesterol can lead to plaque build-up in arteries, increasing the risk of heart disease and stroke. Conversely, high levels of HDL cholesterol are considered protective as they help transport cholesterol away from artery walls. Regular monitoring of cholesterol levels through blood tests is key for assessing cardiovascular risk and guiding dietary and lifestyle interventions or medication management to maintain heart health.
