Low density lipoprotein is converted from very low density lipoprotein. The main function of low density lipoprotein is to transport cholesterol to all cells in the body, mainly to the liver to synthesize cholic acid. Each lipoprotein carries a certain amount of cholesterol, but the most cholesterol is low-density lipoprotein. A large part of low-density lipoprotein in the body is absorbed into the liver and tissues outside the liver through receptor media. After metabolism is eliminated, some remaining low-density lipoprotein is eliminated by scavenger pathway. In the non-receptor pathway, macrophages bind to low-density lipoprotein and absorb cholesterol in low-density lipoprotein. Then cholesterol will stay in the cells, and low-density lipoprotein can enter the arterial wall cells, and then bring cholesterol into the arterial wall cells, so if the low-density lipoprotein level is high, it will lead to atherosclerosis and make people prone to coronary heart disease. ? The main reason for the high low density lipoprotein is unreasonable diet, such as high fat and high calorie diet, which causes excessive fat accumulation in the body; Excessive smoking and alcohol abuse; Less exercise, obesity; Excessive mental stress and low mood; There are also genetic factors. Low-density lipoprotein is on the high side, and it is best to have a light diet. Eat less spicy, fried, fried, strong spirits and other indigestible and irritating foods, eat more fruits and vegetables, fibrotic foods, drink more water at ordinary times, stay away from sugar, salt and lard, and eat more black sesame seeds, mushrooms and black rice. There is also the need to strengthen exercise.
