Eating honey can cause an increase in blood sugar. Honey is rich in sugar, and the glycemic index is high, belonging to the high glycemic index food, so after eating honey blood sugar will rise, if a one-time large amount of honey will also lead to large fluctuations in blood glucose, so patients with diabetes should eat less honey, especially diabetic patients with poor glycemic control should be avoided to eat honey. In addition to honey, cakes, milk tea, sugary drinks, cookies, chocolate and other high-sugar foods, diabetic patients should also avoid eating, otherwise it is not conducive to blood sugar control. Patients who need to control their blood sugar should maintain a low-sugar diet and, if necessary, take medication under the guidance of a doctor.
