Patients with high LDL cholesterol are advised to consume less sugar. In the case of high LDL cholesterol, if the intake of sugar is too much, it will increase insulin resistance, such as impaired glucose tolerance, etc. Excess sugar will also be converted into fat in the liver, which will cause further elevation of blood lipids. Patients with high LDL cholesterol should pay attention to a light diet, avoid eating too much fat-containing food, such as fried food, etc., eat more fresh vegetables and coarse grains, and eat less food with high sugar content. Patients with high LDL cholesterol are advised to have regular monitoring of blood lipids, blood glucose, blood pressure and cardiovascular health risk assessment.
