GLOSSARY

Lipids refer to different types of lipoprotein, which are cholesterol-carrying molecules in the blood. They include low-density lipoprotein (LDL) and highdensity lipoprotein (HDL). LDL is commonly known as “bad cholesterol” because too much can cause the artery walls to harden and thicken, thereby increasing the risk of heart disease. HDL is commonly called “good cholesterol”, because high levels are thought to protect against heart disease. Triglycerides, which are fats found in the bloodstream, are measured at the same time. High levels of triglycerides increase the risk of heart disease.
