Hello everyone, I am Brother Eagle, there is a golden fruit of wisdom in the legend, which is the good fruit of health care given to mankind by the heavens, and Shakyamuni ate this golden fruit and pushed open the door of wisdom and became the revered Shakyamuni Buddha, how about it? Doesn't it sound like a plot from Xiu Xian's novel? There is even a little bit of the idea of tasting, some people have to say, if this fruit really exists, it must be the object of contention, causing the bloody rain of the rivers and lakes, so at least there is no now, coincidentally, there is no absolute in the world, this fruit is really there, and from a very ancient time as food into people's lives, very common, cheap, but most people must have eaten a lot, fragrant and sweet, but also can do a variety of snacks and delicacies, there must be someone to say, Brother Eagle, have you learned to flicker in the new year? You have wronged Brother Eagle, but today is different from the past, and now this fruit may be at risk of extinction, so let's take the last train of wisdom with Brother Eagle before they become extinct.
Publish the answer, this kind of cheap wisdom fruit, is the banana, there is a guess of the audience can get verbal praise once, well, today the skin here, the following is the serious science, of course, although not like the legend to eat bananas immediately IQ explosion, comparable to Einstein and Hawking, but it will indeed bring many benefits to mankind, because it is a high-calorie food, in the tropics and even some countries to eat it as rice, and the status of bananas is not lower than rice, wheat, corn Oh, It even fills the stomach of half a billion people around the world, the nutritional value of banana pulp is quite high, he also has glycoprotein, fat, vitamins, ABCE, as well as potassium, magnesium two elements, can enhance human resistance, promote normal growth and development of the human body, and can also help protect the human body's reproductive ability and vision, but also protect the nervous system, stabilize the human body's serotonin and melatonin.
And make the muscles relax to make you feel comfortable, then when the mood is not good or when the work is tired, come to a bar, chocolate crispy banana, two-pronged line, in addition, it also has dietary fiber, can promote digestion, and enhance satiety, but there is a point to remember that bananas can not be eaten on an empty stomach for a long time, because long-term fasting banana taste, will lead to banana components in the banana components of the cellulose and other components in the stomach digestive enzymes and stomach acid under the action of solidified into water-insoluble solids, accumulation, and then the formation of hard stomach plant stones, Affect gastrointestinal health, at the same time, based on the impact of bananas on blood sugar is not very high, a medium-sized banana calories are about 120 calories containing about 30 grams of carb and 3 grams of fiber, can maintain about 45 minutes of strenuous exercise, which proves that bananas are very good muscle fuel, plus bananas can sweep away depression, keep happy to fight fatigue, so bananas are also fitness weight loss world reds, speaking of this, many small partners must have doubts, How come bananas that can be bought in any supermarket are suddenly on the verge of extinction?
In fact, bananas are not the first time is about to go extinct, I don't know if you have eaten banana-flavored food, ice cream pudding, small cakes, etc., most of these foods are added to the banana flavor, there may be small partners will feel that banana-flavored food is more delicious than bananas, banana flavor is more intense, the taste is sweeter, sometimes feel that it is not the food factory in order to meet the taste buds deliberately increase the banana flavor, indeed your sense of taste is not wrong, this pot can not be thrown to the flavor of the food factory, That's because the bananas that used to be this flavor, that is, the first generation was widely planted, but now it is almost extinct bananas, big mac bananas, some people call it rice seven, bananas into human life for almost as long as the history of human civilization.
As early as 5000 years ago, the indigenous people of Abu New Guinea began to domesticate wild bananas, wild bananas originally matured there will be a lot of seeds, the flesh is very small, not delicious, after entering the Age of Discovery, the Portuguese merchants at that time brought bananas from Southeast Asia to Central America, and after a long period of breeding by humans with foodie attributes, for a long time, bananas finally became the way we eat now like only meat without seeds, this popular look of course to be planted in large quantities, And began to commercialize, and the earliest widely planted varieties are what we just said big mike, this kind of banana and now common bananas, look different, and the fragrance is strong, the skin is also relatively thick, can withstand the long-distance storage and transportation at that time, deeply loved by people in various countries.
But the good times are not long, the early 20th century Big Mack banana was attacked by yellow leaf disease, which made the production of bananas directly avalanche, 1923 American song "Yes, we don't have bananas" said that the bananas because of yellow leaf disease and supply shortages, this yellow leaf disease is actually caused by a fungus called Fusarium ceraspora, it can parasitize the root of bananas and release cytotoxins harmful to bananas, causing banana leaves to turn yellow, eventually the whole plant withers, and triploid bananas can not be sexually reproduced, This also means that, except for occasional genetic mutations, the world's big mac bananas are the same set of genes, in other words, no big mac banana can resist the invasion of fusarium, all will lose, people at that time called this disease Panama disease, also known as three dynasties cancer, at that time all antifungal drugs had no effect on this disease, and this fungus is very cunning, but where the land where bananas are infected with a little fungus, they can destroy the entire banana orchard, and the replanted big mac banana will continue to wither, So around 1960, a large number of banana plantations were forced to be abandoned.
In 1965, the Americans ate the world's last batch of large mac bananas, since then the big mac banana almost extinct from the world, only part of the small plantation that has not been infected by fusarium may have a little big mac banana, scientists named this fusarium yellow leaf disease tropical type 1, referred to as TR1, this bacteria is very tenacious, not afraid of the cold in winter nor afraid of the summer heat, almost directly tell human beings a few words, you take me for a rut, fortunately after the efforts of experts, New anti-viral bananas mushroomed, around 1947, the fastest standard fruit company began to screen from these varieties, according to the taste, flavor and economic benefits, selected the sprout banana as a new generation of widely grown varieties, now people in the supermarket, fruit shop to see the banana, almost all are sprout banana, but the history is always strikingly similar, the big Mack's encounter began to stage again.
In the 1990s, a new type of yellow leaf disease appeared, referred to as TR4, which can now infect two generations of bananas at the same time, and TR4 has become more cunning, they can survive in the soil for more than 30 years, and also learned the incubation period of disease, people walk in the park that has been infected, but there are no specific symptoms, people will bring the infected soil to other places, TR4 can expand its territory in the new land, at present, the planting areas in Africa, the Middle East, Asia and other places have been attacked by TR4, bananas have begun to significantly reduce production again, and other uninfected planting areas, TR4 infection is also sooner or later.
The entire banana industry is once again facing the disaster, in addition, the temperature caused by the greenhouse effect may also bring the danger of extinction to bananas, although bananas are tropical fruits, but prefer the environment of 24-32 degrees Celsius, like human body temperature more than 38 degrees even if the fever is the same, bananas will also be affected, scientists have studied bananas in Hainan, they found that from 1971 to 2000, Temperatures in Hainan rose by 0.3 degrees, the minimum temperature by 1.2 degrees, and the area where bananas grew was suitable for 4 percent.
The rapid rise in brazilian temperatures in 2014 led to bananas beginning to rot, so some scientists believe that according to the current trend, the temperature in 2050 is likely to be no longer suitable for banana growth, so what should be done to save bananas? In addition to physical isolation, scientists have actually been cultivating new disease-resistant varieties, just like the replacement of the big mac with the sprout banana, but the banana varieties are extremely complex to cultivate, so this road is also full of thorns, while also taking into account the taste of bananas on the basis of disease resistance, the process is relatively long overall, and people also hope that genetic engineering, especially the technology of genetic engineering is becoming more and more mature, perhaps it is possible to directly modify genes to obtain disease-resistant varieties. Let the banana through genetic programming to obtain disease resistance is the main direction of research in this field of scientists, once successful, the new sprout banana can be widely planted around the world, even the big mac of the year can also reproduce the human world, but many people have a strong sense of distrust of the food produced by genetic technology, how to obtain people's trust in genetic food, is also an important issue.
However, Eagle Brother believes that with the advancement of science and technology, bananas such a delicious fruit will not be extinct from the world, new banana varieties are only a matter of time, of course, if you want to contribute a little more to the preservation of bananas, you can buy a flower pot, and then buy a dwarfed banana tree, in addition to beautifying the home environment, you can also eat your own personally grown bananas, so talk about it today, remember the pipe cone praise the next update is more interesting, goodbye
