What is actively considered "bad cholesterol"?

Low-Density Lipoprotein (LDL) is often referred to as "bad cholesterol" due to its role in transporting cholesterol in the bloodstream. High levels of LDL can lead to the buildup of plaque in the arteries, which increases the risk of cardiovascular diseases such as heart attack and stroke. This is in contrast to High-Density Lipoprotein (HDL), commonly known as "good cholesterol," which helps to remove cholesterol from the bloodstream and transport it to the liver for excretion or re-utilization.

Triglycerides are a type of fat found in the blood and can also contribute to the risk of heart disease when present in high amounts, but they are not classified specifically as cholesterol. Chylomicrons are lipoprotein particles that transport dietary lipids from the intestines to other locations in the body, and they play a different role in lipid metabolism.

Understanding the distinction between LDL and HDL, along with the role of triglycerides and chylomicrons, is essential in managing heart health and making informed lifestyle choices related to diet and exercise.
