Low-density lipoprotein

Low-density lipoprotein is one of the important criteria to measure whether your liver is healthy and whether the cholesterol in your blood is normal. If the low-density lipoprotein is too low, it means that there is something wrong with your liver metabolism or your fat intake is too low. Therefore, during your regular physical examinations, you must pay attention to whether your low-density lipoprotein values ​​are normal so that you can better understand your physical condition.

However, many friends feel that low LDL is related to disease. Does this mean that the higher it is, the better? This is completely wrong. If your body is in a healthy state, its value is definitely within the normal range. Therefore, no matter whether your LDL is low or high, you should not ignore it.

Low-density lipoprotein (LDL) is derived from very low-density lipoprotein (VLDL). Its main function is to transport cholesterol to cells throughout the body and to the liver to synthesize bile acid. Each lipoprotein carries a certain amount of cholesterol, and the lipoprotein that carries the most cholesterol is LDL. Two-thirds of the LDL in the body is absorbed into the liver and extrahepatic tissues through receptor-mediated pathways and cleared through metabolism. The remaining third is cleared through a "sweeper" pathway, a non-receptor pathway in which macrophages bind to LDL and absorb the cholesterol in the LDL so that the cholesterol remains inside the cell, becoming a "foam" cell. Therefore, LDL can enter the cells of the arterial wall and carry cholesterol with it. Excessively high LDL levels can cause atherosclerosis, putting individuals at risk for coronary heart disease.

Low-density lipoprotein: the "bad" cholesterol in the blood

Blood lipids mainly include two components: triglycerides and cholesterol, which mainly come from the food we eat daily and are synthesized in the human body. Cholesterol can be divided into two types: low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Low-density lipoprotein cholesterol is "bad" cholesterol, and high-density lipoprotein cholesterol is "good" cholesterol. Dyslipidemia mainly refers to the increase of triglycerides and "bad" cholesterol, and too low "good" cholesterol, which is the main cause of coronary heart disease and cerebral thrombosis.

After knowing the relationship between low-density lipoprotein and human health, if you want to prevent low low-density lipoprotein in your daily life, please pay attention to the rationality of your diet. The fat intake must not be too high or too low, which will affect the level of low-density lipoprotein.
