Which type of cholesterol is considered "bad" cholesterol?

Low-Density Lipoprotein (LDL) is considered "bad" cholesterol due to its association with an increased risk of cardiovascular diseases. LDL carries cholesterol from the liver to the cells, but when there is an excess of LDL in the bloodstream, it can lead to the buildup of plaque in the arteries. This buildup can restrict blood flow and increase the risk of heart attacks and strokes.

In contrast, High-Density Lipoprotein (HDL) is known as "good" cholesterol because it helps remove cholesterol from the bloodstream and transports it back to the liver, where it can be processed and eliminated. Triglycerides are a type of fat found in the blood and are evaluated separately from cholesterol levels, although high levels can also increase cardiovascular risk. Very Low-Density Lipoprotein (VLDL) primarily carries triglycerides and is considered less favorable than HDL, but it is not as prominently labeled as “bad” as LDL is. Consequently, the designation of LDL as "bad" cholesterol highlights its role in promoting cardiovascular health issues.
