Taboo problem
1, avoid eating undercooked bananas.
Immature. Bananas are prone to constipation.
As we all know, when bananas are immature, the skin is turquoise, and after peeling, it is hard to swallow. Mature bananas, with astringent taste swept away, are soft, waxy and sweet, and are deeply loved by children and the elderly. 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. All bananas we eat in the north are ripe before they are cooked. The astringency of raw bananas comes from the large amount of tannic acid contained in bananas. When the banana is ripe, although it can't taste astringent, tannic acid still exists. Tannic acid has a strong astringent effect, thus causing constipation. The most typical thing is that after eating bananas, the elderly and children can't help but defecate, but they can have obvious constipation.
2. Avoid eating bananas on an empty stomach
We say bananas can be used as food, but we can't eat them in large quantities on an empty stomach. Because bananas contain a lot of potassium, phosphorus and magnesium, for normal people, a large intake of potassium and magnesium will make sodium and calcium in the body out of balance, which is not conducive to health. So don't eat too many bananas on an empty stomach.
3. Avoid eating too many bananas.
Excessive consumption of bananas will lead to imbalance of trace elements.
Banana is a delicious fruit, so some people eat many bananas at a time. As we all know, this is very bad for your health. 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. Therefore, bananas should not be eaten in excess.
4. Bananas should not be stored in the refrigerator.
As we all know, bananas are picked when they are ripe in June and July, because they ripen quickly. If they are picked when they are ripe, they taste bad and look stale. Then, after bananas are picked, the storage temperature is also high, generally 1 1- 13 degrees Celsius, while the fruits and vegetables stored in the refrigerator are generally around 4 degrees Celsius, up to 8 degrees Celsius. Bananas are easy to freeze if they are placed in this environment. If they are placed for one day, they will turn black, become soft and rot, and their taste will become worse, even appear patches or rot.
