If you talk about any kind of fruit, it is suitable for all ages, cheap and delicious, and bananas definitely deserve to be famous.

But you know what? The bananas we eat may be at risk of extinction, and there are a lot of “rumours” about bananas. What’s the truth?

First, cold knowledge: we are not eating “real bananas”

Did you know that bananas also have ancestors? Today’s bananas are all cultivars that have been improved and cultivated by humans for many years, and their ancestors came from wild species – small fruit wild banana and wild banana.

The fruits of these two wild plants have large, hard seeds and an unpalatable taste. In order to be more suitable for human taste, people continue to improve it. Today, the bananas we eat belong to triploid plants, and their ancestors Compared with the diploid, the appearance is more attractive, the aroma is fragrant, and there are no seeds in the pulp, so the edible degree is very high.

However, triploids have a defect, that is, they are highly sterile, unable to produce seeds normally, let alone reproduce the next generation.

Although bananas are delicious, but banana plants have very single genetics, and no variety is highly resistant to diseases, susceptible to various fungal diseases and insect pests, and a single disease may “kill” a banana variety.

There was once a delicious main banana variety, the Big Michel, which made a fungal disease disappear from this world.

Today’s bananas are dominated by Chinese bananas, which account for nearly half of the global market. In China, the vast majority of bananas that can be eaten are actually descendants of Chinese bananas. But now these descendants of Chinese bananas are also suffering from banana fusarium wilt. If humans cannot overcome this problem, it is likely that bananas will face a crisis of extinction in the future.

Second, what benefits can you gain from eating bananas?

From a nutritional point of view, each 100g banana pulp contains 15% sugar, 0.2%~0.3% acid, 1.5% protein, 53mg phosphorus, 19mg calcium, 400mg potassium, 24mg vitamin C , and trace elements such as pectin and enzymes.

Banana is a great energy supplement, rich in carbohydrates and potassium< span>, can help maintain the balance of fluid inside and outside cells, relieve muscle tension, and keep exercise in a good state.

Banana also contains certain biogenic amines, which can help regulate mood. When people eat bananas, they will feel relaxed and happy.

Banana is one of the most nutritious fruits, but not everyone is suitable for consumption. Banana is high in potassium, so it is not advisable to eat more for people with chronic nephritis and renal insufficiency.

3. Can a banana after a meal relax the bowels?

Although it is often said that bananas can laxatives, this effect is actually very limited. Even if you eat less ripe bananas, it may worsen constipation. What is going on? ?

Laxative and dietary fiber are closely related. Usually, moderate amounts of dietary fiber help relieve constipation. Dietary fiber includes soluble fiber (pectin) and insoluble fiber (such as cellulose).

Although dietary fiber cannot be digested by the human body, it can increase the volume of feces and promote intestinal peristalsis, that is to say, in moderate amounts The dietary fiber is beneficial for relieving functional constipation.

butbananas are not high in dietary fiber, generally containing Soluble fiber is 1.1g/100g. Compared with other fruits, Sydney (3.0g/100g) and dragon fruit (2.0g/100g), it has no advantages.

Why do some people eat bananas and feel relieved from constipation? This may be related to fructose intolerance. Fruits are rich in fructose, which can cause diarrhea when fructose intolerance occurs.

Banana is not only inconvenient, but eating immature bananas will aggravate constipation.

Unripe bananas contain tannins (tannins), which are astringent and can cause dry stools. Banana works well for people with diarrhea.

So which fruit is more laxative? Fructose, dietary fiber, and sorbitol have the ability to exert pressure, expand, and soften, thereby relieving stool difficulties.

According to the ingredients, the first choice is prunes, followed by dragon fruit, pomegranate, pear, kiwi, strawberry, apple, etc. are also good laxative fruits, can be eaten in moderation.

4. How many do you know about bananas?

“Banana red is right and wrong”, are these rumors about bananas true or false?

1, do bananas have nuclear radiation?

Banana does have radiation, but not just bananas, but many fruits. The radiation in bananas is mainly related to the radioactive element potassium-40.

But the radiation dose is as tiny as dust compared to the cancer-causing radiationa chest CT The radiation dose is equivalent to the radiation dose of 70,000 bananas, and the excess potassium can be metabolized by the human body, so don’t worry too much.

2, can bananas with long spots be eaten?

Spotted bananas do not mean bananas are “broken”. In fact, just like human skin, aging will also cause “age spots”, which is a manifestation of maturity. In addition, bananas are afraid of cold and falling. If they are frozen or subjected to physical attacks, they will also develop spots and discoloration. Just peel off the skin of the banana, and the pulp is still white and tenderand you can eat it.

3, can’t bananas be taken with milk?

Can bananas and milk cause diarrhea? In fact, it is just a manifestation of fructose intolerance or lactose intolerance. This is a sign that some people are lacking some enzymes in their bodies. For most people, bananas and milk may be similar to “banana milkshake” and taste very good.

4, ripe bananas, will they ripen early?

The ripening plant hormone in bananas is ethephon. Its main function is to “ripen”, but it basically has no effect on the human body. Precocious puberty has nothing to do, you don’t have to smell too much “hormone” to change color.

Banana may be the most cost-effective fruit. I hope that human beings can conquer harmful bacteria as soon as possible and keep bananas.
