1, which can prevent or treat hypertension.

Because bananas are rich in potassium, they can excrete too much sodium ions and lower blood pressure. Another ion that lowers blood pressure is calcium, so if you cut bananas into small pieces and mix them with calcium-rich milk in a blender, it will become the best antihypertensive juice.

2, can prevent and relieve constipation.

Bananas contain a lot of fiber, which can stimulate gastrointestinal peristalsis, increase the volume of feces and help defecation.

3. Prevention and treatment of gastric ulcer

Patients with gastrointestinal ulcer often take phenylbutazone, which often leads to gastric bleeding. Banana contains a chemical that can prevent gastric ulcer, which can stimulate the growth and reproduction of gastric mucosal cells and produce more mucosa to protect the stomach.

Step 4 lose weight

Bananas are easy to get full because of their high starch content. It takes some time for starch to be converted into sugar in the body, so it will not produce excessive energy (energy food) accumulation. From this point of view, bananas can be the first choice to lose weight.

Disadvantages:

1, excessive consumption of bananas will cause imbalance of trace elements.

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.

Eating more bananas will increase the burden on the kidneys.

Eating too many bananas is particularly bad for people's kidneys, especially for patients with nephritis and renal insufficiency. After eating a lot of bananas, the symptoms will be obviously aggravated, because the sodium content in bananas is relatively high, which will increase the burden on the kidneys and aggravate the symptoms of nephritis. Therefore, those patients with renal insufficiency and nephritis should usually eat less bananas.

Eating more bananas will make people feel numb.

Eating more bananas will make the human body absorb a lot of potassium. After this substance enters the blood, it will have obvious inhibitory effect on human cardiovascular and cerebrovascular diseases, causing muscle paralysis or numbness. Some people will feel sleepy and weak if they eat too many bananas.

Extended data

Taboos for eating bananas:

1, immature bananas are easy to cause 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.

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. After the banana is ripe, although the astringency is no longer tasted, the tannic acid component still exists.

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 eating bananas, the elderly and children can't help but defecate, but they can have obvious constipation.

2. 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.

3. 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.
