Cholesterol is a waxy, fat-like substance found in every cell of the body, essential for producing hormones, vitamin D, and bile acids that help digest fat. It is carried through the bloodstream by lipoproteins, primarily low-density lipoprotein (LDL) and high-density lipoprotein (HDL). While the body needs cholesterol for vital functions, high levels of LDL cholesterol can lead to plaque buildup in arteries, increasing the risk of Heart disease and stroke. Maintaining balanced cholesterol levels is crucial for overall health.
