Empty stomach can generally eat bananas, but can not eat too much. Bananas contain a variety of nutrients, including protein, vitamins, potassium, calcium ions and other nutrients, as well as dietary fiber, which can provide the body with a certain amount of nutrients, replenishment of energy, to maintain the normal physiological functions of the body. Eating bananas on an empty stomach generally does not cause adverse effects. However, it is important to note that you should not eat too much at a time, so as not to increase the burden on the stomach and intestines. Especially for patients with gastrointestinal diseases, it is recommended to heat them before eating. In addition, try to choose ripe bananas, because unripe bananas contain ellagic acid substances, aggravating the burden on the stomach and intestines. Note that diabetic patients with unsatisfactory blood glucose control should try to eat less or no bananas, which may cause fluctuations in blood glucose, aggravate the burden of insulin and affect blood glucose control.
