Blood lipids, including total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and triglycerides, are important indicators of our health. While cholesterol is essential for our bodies, excessive levels can lead to health issues such as arteriosclerosis. HDL is considered "good" cholesterol as it helps remove excess cholesterol from the bloodstream, whereas LDL is considered "bad" cholesterol as it can contribute to the buildup of plaque in the arteries. Understanding our blood lipid levels and taking steps to maintain healthy levels can help prevent cardiovascular diseases. If you have concerns about your blood lipid levels, consult with your doctor to determine the best course of action.
