Maltose is not recommended for patients with high blood sugar. The glycemic index of maltose is very high, which belongs to high glycemic index food, and the calorie is also high, so patients with high blood sugar may cause blood sugar to rise rapidly after eating maltose, which is not conducive to the control of blood sugar and maintenance of blood sugar stability in patients with high blood sugar. In daily life, patients with high blood sugar should also avoid eating other high sugar foods, such as cakes, cookies, milk tea, chocolate, candies, etc., and can eat some vegetables, dairy products and other low-fat, low-sugar foods, which can help control blood sugar. Patients diagnosed with hyperglycemia who are not clear about the relevant dietary taboos can go to the hospital and consult a specialist.
