When you receive your annual health screening, one of the things that you get tested for is your cholesterol level. Cholesterol is a waxy, fat-like substance that's found in all cells of your body. Your body needs cholesterol to help produce certain hormones, cell membranes, vitamin D, and bile acids that aid your digestive system.
Many adults are hard-wired to believe that cholesterol is bad for your health. This is only partly true. High levels of low-density lipoprotein (LDL) cholesterol (the bad type of cholesterol) can lead to an increased risk of heart disease. However, high-density lipoprotein (HDL) cholesterol (the good kind of cholesterol) is great for your overall health and helps reduce your risk of developing heart disease.
According to WebMD, HDL cholesterol can help reduce your risk of heart disease by:
- Removing LDL cholesterol
- Transporting LDL cholesterol it to the liver where it can be reprocessed
- Acting as the maintenance crew for the inner walls of your blood vessels – HDL scrubs the wall clean and keeps it healthy
