The public also wants to know, what is the magic of bananas? Why do cute girls love bananas so much?

There are thousands of kinds of fruits. Why do athletes spoil bananas alone? What are the benefits of eating bananas for your health?

Bananas are good friends of athletes.

A few years ago, someone did an experiment. Participants in a bicycle race were randomly divided into two groups. One group only drank water, and the other group drank banana oil. The results showed that in this competition, the athletes who drank banana oil were 5% faster than the other group, and their physical strength recovered faster.

This is because bananas contain a high proportion of carbohydrates and a certain amount of protein, carotene, potassium and cellulose, which are not only high in monosaccharides, but also contain disaccharides and polysaccharides. They are very suitable for athletes and are the key to keep them energetic on the field.

It is particularly worth mentioning that the potassium content in bananas is as high as 472 mg, which is the highest in fruits.

Medical research shows that potassium deficiency will lead to general weakness, which will lead to abdominal distension and intestinal paralysis. In severe cases, it will also affect myocardial contraction, cause arrhythmia and induce heart failure.

During the competition, athletes will consume a lot of energy, which is also a great test for potassium in the body. If you eat a banana during the competition, you can effectively supplement the potassium in your body and meet the demand for potassium.

In addition, some studies have found that the substances contained in bananas can help the human brain to produce 5- hydroxytryptamine, which makes people feel peaceful and happy. In other words, bananas can help athletes, relieve psychological stress and relieve depression. The stadium is like a battlefield, and every athlete is struggling under great pressure. Eating a banana can help them ease their nervous mood and stabilize their mentality.

So bananas are good friends of athletes.

Can everyone eat bananas?

Bananas are rich in potassium, which helps to balance the salt in our bodies and prevent high blood pressure. Therefore, patients with hypertension can eat bananas, but they can never replace drugs. In addition, bananas can also reduce the incidence of stroke, and heart patients are also suitable to eat bananas.

It is worth noting that bananas are cold, and older people (especially those with spleen and stomach deficiency) should eat carefully or eat less to avoid abdominal pain and diarrhea. For diabetics, bananas should be limited to avoid raising blood sugar.

Patients with renal insufficiency, oliguria and nephritis should not eat bananas. Because of limited renal function, their excretory function declines, which hinders the excretion of metabolites in the body. Eating bananas with high potassium content will make it difficult to excrete too much potassium in the body, leading to hyperkalemia, cardiac arrest and even life-threatening.

In addition, bananas contain a small amount of tannin, especially in immature bananas. People who want to eat bananas to relieve constipation must pay attention to choosing ripe bananas to eat, otherwise it may be counterproductive.

Unexpectedly, a small banana also has a university question. When you see someone eating bananas in the future, you can give popular science to people around you!
