The lower the LDL, the better. The main function of LDL is to transport cholesterol to extrahepatic tissues, which has a more potent atherogenic effect, so the lower the better. The proportion of cholesterol in LDL is particularly large, and its main function is to transport cholesterol to extrahepatic tissues. It is an important lipoprotein leading to atherosclerosis, and after oxidation and chemical modification, it has a stronger atherogenic effect, so the lower the LDL, the better. Once the LDL is found to be elevated, one should consult a doctor in time and standardize the treatment under the doctor’s guidance, such as oral atorvastatin, low-fat diet in daily life, appropriate exercise, and maintaining a proper weight.
