Patients with diabetes can eat some grapes appropriately, but should pay attention to the following points: first point, patients with diabetes should ensure that their blood sugar control is relatively stable before they can choose some fruits to eat, including grapes. Because if the patient’s own blood sugar control is relatively poor, then additional intake of fruit will make the patient’s blood sugar control further become serious. The second point, when eating grapes must pay attention to control the amount of grapes, because the sweeter types of grapes, eat too much at a time will also have a more obvious effect on blood sugar. Thirdly, it is better for patients to eat grapes before meals, not after meals, as eating grapes after meals may aggravate postprandial blood glucose elevation, thus adversely affecting blood glucose control.
