There are many people around me who like to eat bananas. I also like it very much. But I am a face-looker. When I choose a banana, I will rule out the appearance of spots. I thought most people would like this. However, listening to my colleagues today said that the long-spotted bananas have better nutrition. Is this true?
Why do bananas have long spots?
Bananas, like other plants, are also harmful. Such as yellow leaf disease, anthrax, black spot disease, flower thrips, split fruit disease, and so on. Among them, suffering from anthrax causes bananas to show black spot symptoms. Anthracnose is a fungal disease caused by the bacterium Staphylococcus aureus. This condition will only appear when the banana is ripe.
However, eating this kind of banana is not harmful to the body. Because anthrax is only a banana infringement, it has no effect on man-made. What's more, the anthrax bacteria that make bananas dark and the anthrax virus have nothing to do. Of course, they cannot cause diseases. But if the banana's flesh is already dark, don't eat it.
In fact, it is not just the anthrax that causes the bananas to be spotted, and the bananas will darken when placed for a long time. This is because the banana epidermal cells contain a type of oxidized carbon. Normally, the cell membrane protects the oxidized carbon tightly, just as the human skin protects flesh and bones. Once it is bumped or frozen at low temperatures, the cell membrane breaks. The oxidized carbon inside comes into contact with the oxygen in the air, and the oxidation of oxygen becomes black, and some tiny spots naturally appear.
Banana long spot more cancer?
There is a widespread claim on the Internet that "black spots are more resistant to cancer." Is this true? Although there is no theoretical basis for this conclusion at the moment, long-spotted bananas are indeed better than those without spots. Because the long spot of bananas means that it has matured, it has a milder immune activation and is more beneficial to physical and mental health.
Therefore, in daily life, we may wish to eat 1-2 bananas a day to prevent infection by improving the body's resistance to disease, especially to prevent the spread of viruses such as colds and flu.
Although it is good to eat long-spotted bananas, there are some precautions:
1, physically deficient people should not eat bananas
Bananas are cold and physically deficient in cold, such as cold stomach, cold (diarrhea, dizziness), nephritis, swollen feet in pregnancy, it is best not to eat bananas.
2, should not eat bananas on an empty stomach
Banana contains a large amount of magnesium, if a large number of fasting bananas, will cause a sudden increase in the amount of magnesium in the blood, resulting in the imbalance of magnesium and calcium in human blood, inhibition of cardiovascular and adverse health.
3, arthritis, diabetes, nephritis and other patients should not eat bananas
Higher levels of some components of bananas, such as sugar, potassium, magnesium, etc., will make the disease worse.
4, hyperacidity should not eat, stomach pain, indigestion, diarrhea should also eat less bananas.
5, if you want to achieve the effect of beauty to lose weight, it is recommended to eat a little more bananas, because the heat of ripe bananas is high, on the contrary, raw bananas will instead play a role in the consumption of excess fat.
6, bananas can be kept at 12 ~ 13 degrees Celsius, should not be stored in the refrigerator.
