Bananas have higher magnesium content. Magnesium is a sensitive element that affects heart function and has an inhibitory effect on cardiovascular system. Eating bananas on an empty stomach will suddenly increase magnesium in the human body, destroy the balance of magnesium and calcium in human blood, and thus inhibit the cardiovascular system, which is not conducive to health.

Bananas are delicious fruits, so some people (acute and chronic nephritis, renal insufficiency) eat bananas in large quantities at one time. Bananas contain more elements such as magnesium and potassium. Although these mineral elements are necessary for human health, if they are ingested too much at one time in a short period of time, the contents of magnesium and potassium in the blood will increase sharply, resulting in the imbalance of potassium, sodium, calcium, magnesium and other elements in the body, which is harmful to health. In addition, eating more bananas will also cause gastrointestinal dysfunction and excessive mood swings due to the greatly reduced gastric acid secretion.

When the banana is immature, the skin is turquoise, and it is too astringent to swallow after peeling. Bananas are tropical and subtropical fruits. In order to facilitate storage and transportation, when picking bananas, you can't wait until the skin is green. The astringency of raw bananas comes from the large amount of tannic acid contained in bananas. Tannic acid has a very strong astringent effect, which can form dry and hard feces, thus causing constipation. The most typical thing is that after the elderly and children eat bananas.
