Banana is a common fruit in our life. Banana has the function of lowering blood pressure and blood fat. Because bananas are rich in vitamins and low in sodium and cholesterol, eating bananas often helps to reduce the incidence of hypertension and hyperlipidemia. In addition, bananas also have the functions of clearing away heat and promoting fluid production, quenching thirst and relieving annoyance, helping digestion and relaxing bowels. Bananas are also effective for fever, polydipsia and constipation, and have an auxiliary effect on constipation. Banana can also protect the stomach wall and prevent and treat gastric ulcer, mainly because the angiopoietin-converting enzyme inhibitor contained in banana can repair gastric ulcer induced by some drugs. Bananas can also promote sports, because bananas contain a lot of potassium, and potassium ions can enhance muscle strength and endurance, so they are especially suitable for people who do a lot of exercise, such as athletes. Eating bananas regularly can also help you lose weight, because bananas contain almost all vitamins and minerals, and are a fruit rich in dietary fiber and low in calories. But you should pay attention to a few points when eating bananas. First, bananas should not be eaten on an empty stomach, especially with taro. People with spleen and stomach deficiency and diarrhea should not eat more. Also, don't eat bananas after they turn black, which is not good for your health.
