Which lipid is considered bad cholesterol?

• A. LDL
• B. HDL
• C. Triglycerides
• D. VLDL

Answer: (A)

The concept here is how cholesterol is labeled as “bad” or “good” based on what a lipoprotein does in the body. Low-density lipoprotein is considered bad cholesterol because it transports cholesterol to tissues, including the arteries. When LDL levels are high, more cholesterol is deposited in the arterial walls, which can lead to plaque formation, narrowing of the arteries (atherosclerosis), and a higher risk of heart attack or stroke. In contrast, high-density lipoprotein helps remove cholesterol from arteries and return it to the liver for disposal, which is why it’s viewed as protective or “good.” Triglycerides are a different type of fat in the blood, and while high triglycerides are a risk factor for cardiovascular disease, they aren’t called “bad cholesterol.” VLDL also carries triglycerides and can contribute to atherogenesis, but the label “bad cholesterol” in common usage most specifically refers to LDL.
