Diabetic patients’ diet control is one of the most important means to treat diabetes, in which the salt intake should not exceed 6g per day, because diabetic patients are often combined with hypertension and atherosclerosis, and if they consume too much sodium chloride, it can lead to aggravation of atherosclerosis and make it difficult to control blood pressure. Therefore, it is recommended that diabetic patients should not consume more than 6g of salt per day, and that they should reduce the intake of soy sauce, cooking oil, MSG, and other condiments containing high sodium chloride such as Flavor Delta. Therefore, for diabetic patients, strict control of sodium chloride intake is beneficial for blood pressure control, avoiding the aggravation of atherosclerosis, preventing the occurrence of cardiovascular and cerebrovascular diseases to a certain extent, which is beneficial for the control of the patient’s condition.
