Eating instant noodles for a long time may cause high LDL. LDL is one of the indicators in the blood lipid test, which can be used to determine the presence or absence of hyperlipidemia, atherosclerotic disease, and so on. Instant noodles are a kind of high-calorie, high-salt, high-fat food. Eating instant noodles once or twice in a while will not cause LDL elevation, but if you eat instant noodles regularly for a long period of time, it may cause elevation of blood lipids and LDL elevation. In daily life, both healthy people and patients with hyperlipidemia are recommended to eat less or not eat instant noodles, maintain a healthy diet, and if dyslipidemia occurs, it is recommended to go to the hospital and ask the doctor to make a judgment.
