A grande richiesta... Cholesterol is a waxy-like substance that insulates nerve fibers and is needed for production of certain hormones. But, when there’s too much in your blood, cholesterol-rich plaque builds up along blood vessel walls. Overtime, this buildup causes narrowing of the arteries, impeding blood flow and leading to heart disease or stroke. Cholesterol is packaged in protein-rich, water-soluble “bubbles” called lipoproteins. Being water-soluble allows these carriers to transport the fatty cholesterol in the watery medium of the blood. Low-density lipoprotein-cholesterol, also called LDL or the “bad” cholesterol, is the cholesterol being carried throughout your body. Elevated LDLs increases cardiovascular disease (CVD) risk. High-density liporotein cholesterol, also called HDL or “good” cholesterol, is cholesterol being cleared from the body, it protects against CVD. Photo credit: *Blunight 72* via Compfight
