LDL cannot be lowered by eating food, but eating some soluble dietary fiber can reduce the absorption of cholesterol to some extent. LDL is usually recommended to be as low as possible in clinical practice, as lowering this value can reduce the risk of cardiovascular and cerebrovascular diseases to a certain extent, and it is usually recommended that elevated LDL should be controlled by statin lipid-lowering drugs. Patients with elevated LDL are advised to consume foods rich in soluble dietary fiber, including oats, white beans, eggplant, carrots, and kiwi, etc. Dietary fiber can promote the excretion of intestinal contents, and to a certain extent, can reduce the absorption of cholesterol by the body. Patients with elevated LDL are advised to consult endocrinologists or cardiologists for treatment under medical supervision.
