Patients with diabetes are not recommended to eat bananas. Because the glycemic index of bananas is relatively high, if diabetic patients consume bananas, it will cause a sharp rise in blood sugar in a short period of time, resulting in fluctuations in blood sugar. In general, diabetic patients can eat fruits with a lower glycemic index, such as apples, grapefruit with a white core, kiwi, etc. If blood sugar control is unstable, you can also eat large cucumbers and large tomatoes instead. The recommended time to eat fruit for diabetic patients is to consume about two taels of fruit between meals when blood sugar is under stable control. If the blood sugar is too high, it is not recommended to eat fruits, and too sweet fruits are not recommended to eat. In addition, do not eat fruit immediately before and after meals, but eat fruit between meals.
