What we are saying is that the benefits of bananas are too numerous to count.

As we all know, the elderly, children, and people with bad teeth can eat it. If you are constipated, it can help you defecate. If you are hungry, it can also fill your stomach quickly.

There is one thing you may not know, bananas actually have another name - happy fruit! Eating bananas can actually bring people happiness.

Although bananas have so many benefits, you may not know that they actually have radiation after eating them for decades! So can we still eat bananas safely?

Will eating bananas make you happy?

Bananas are "high-potassium fruits", containing 286-428 mg of potassium per 100 grams. The mineral potassium itself can maintain normal blood pressure and heartbeat, which can help the body prevent high blood pressure and muscle cramps. In addition, the magnesium content in bananas is also remarkable (14.60-40.70 mg/100 grams), and magnesium has the effect of eliminating fatigue.

In addition, the tryptophan contained in bananas can itself be converted into 5-hydroxytryptamine, which is an inhibitory neurotransmitter. After ingestion, it will make the body quiet, promote mood calmness, and reduce pessimism.

Not only that, bananas themselves are rich in carbohydrates, which can be quickly converted into glucose and absorbed by the body after entering the body. This substance is a "quick source of energy", so eating a banana when the body is tired and depressed can quickly replenish physical strength and relieve emotions.

Bananas are delicious and nutritious fruit. In addition to basic energy nutrients, bananas are also rich in nutrients such as riboflavin, thiamine, niacin, and vitamin C. Every 100 grams of bananas contains 60 micrograms of carotene.

Are bananas with spots poisonous and cannot be eaten?

When buying bananas, you may find that "many bananas have black spots". It is rumored that "such bananas cannot be eaten and will cause poisoning if eaten."

In fact, there are two main reasons why spots appear on banana peel or the banana peel turns black.

One is the "natural oxidation of banana peel". When the banana epidermal cells are bumped by the outside world or are in a low temperature environment (frozen), the outer cell membrane will be damaged. The oxidized carbon will inevitably come into contact with oxygen. After the oxidation reaction, it will turn black, and small spots on the outer skin will appear.

Secondly, bananas are also prone to black spot problems after they are "sick" (anthracnose). This problem is caused by bananas being infected with "Banana Sporangium", which is basically a "fungal disease". But don't worry, this pathogen is insulated from humans and will not infect the human body and affect health.

In other words, even if black spots appear on bananas, don't panic, as the two factors mentioned above will not cause harm to the human body. If the banana skin partially turns black (or has small black spots), as long as the internal flesh is not spoiled, it is safe to eat.

Does eating bananas actually cause radiation?

Bananas do produce radiation.

The so-called radiation actually comes from the "mineral potassium" contained in bananas. Bananas are a fruit rich in potassium, and a small part of the "potassium" in them is radioactive "potassium-40"; but containing it does not mean a lot, and the dose is very small, and eating it will not cause harm to the human body.

The amount of radiation is related to the "dose", so the "little bit" of dose in bananas will not cause any harm to the body, so you can eat bananas with confidence.

How to store bananas so they don’t turn black?

01

Basic principle: Buy now and eat now

Fresh food is safer and more nutritious. When buying bananas, it is recommended to buy small amounts at a time and eat them within two days.

02

It is more suitable to store at room temperature

Relevant experiments have proved that a temperature of around 13°C is the best storage temperature for bananas; compared to storage in the refrigerator, bananas stored at room temperature ripen more slowly and are less likely to turn black.

If conditions permit, you can hang bananas up for storage to enhance ventilation. This way, ethylene can disappear faster with the wind, delaying fruit aging.

03

Wrap the banana stems when storing

Since ethylene is the fundamental substance that causes the banana skin to turn black, as the banana ripens, more and more ethylene will be released. Controlling the ethylene around the banana can slow down its ripening rate.

Most of the ethylene comes from the rhizome of bananas. Wrapping the rhizome tightly with plastic wrap can extend the shelf life by about a week.

Although the blackened banana doesn't look that cute

It also produces a negligible amount of radiation.

You can still eat it with confidence
