On the sports field, many athletes eat bananas at the rest time.So why is banana favored by athletes?Does it have any unique advantages?What problems should we pay attention to when eating bananas?
The benefits of eating bananas
Each 100g banana contains about 22g of carbohydrates. It is very rich in content and can supplement the energy needed for athletes.Compared with "energy supplements" such as fat and protein, carbohydrates in bananas are more likely to be absorbed by the body, which can reduce the body’s digestion and metabolic burden, and it is more suitable for some short -term competition items.
After exercise, a large amount of sweat of the body can easily lead to a reduction in the potassium content in the body, which may cause abnormal muscle system and the symptoms of numbness and weakness.Bananas are typical "high potassium fruits", which contains 256mg of potassium every 100g of bananas.Eating a banana after exercise can help supplement potassium, better maintain the osmotic pressure balance of internal and external fluids, alleviate neurotomer tension, and ensure a good motion state.
Banana is a solid food with a strong sense of satiety and can reduce hunger during exercise.Banana’s moisture content is as high as 75%, and it is mainly due to the loss of flowing water. After consumption, the water release speed is slow. It is not easy to make people want to go to the toilet and affect the status of the game.
Contains trace biothams
Bananas, also known as "happy fruits", contain biomamine such as 5-hydroxyline, dopamine, and tormeal adrenaline, which can help regulate emotions.The substance of 5-hydroxyline can make people feel relaxed and happy, which is conducive to alleviating the tension of athletes during the game.
Although the banana is good, it is not suitable for everyone
Patients with kidney disease
The content of potassium in bananas is high, suffering from patients with acute chronic nephritis, renal dysfunction and other patients with nephropathy. The metabolic function of sodium and potassium is abnormal. If you eat a large amount of bananas, you can easily cause hyperkalemia.Symptoms such as slow and blood pressure, so we must control the amount.
Banana’s fruit sugar content is high, more than 14%, but its blood sugar generating index (GI value) is not too high, about 42-58, even if it is diabetic patients, you can eat a small amount of bananas.It should be noted that while eating bananas, pay attention to controlling the diet of the day, especially the intake of staple foods, so as not to cause excessive blood sugar fluctuations; it is best to wait for blood sugar to control smoothly, and then use bananas to replace other staple foods of equal carbon water.Essence
People with poor stomach and stomach
Bananas contain a certain amount of tannic acid. Under the action of gastric acid, it will stick to protein, dietary fiber and other substances, which may cause symptoms such as acute stomach pain, abdominal pain, bloating, nausea, and vomiting.Therefore, some people with weak gastrointestinal function or patients with gastrointestinal diseases will feel gastrointestinal discomfort after eating bananas. These people are not suitable for eating a lot of bananas (including other astringent fruits such as persimmon and other astringent fruits).
In fact, general health people do not have to worry about eating bananas on an empty stomach will affect their health.On the one hand, even if you eat bananas on an empty stomach, the magnesium and potassium in it will only slowly enter the human body, and the amount of body absorption will be limited, and it will not enter the blood instantly like a injection.On the other hand, the human body has an automatic adjustment function. It will metabolize excess magnesium and potassium in the kidneys and skin to maintain the balance of the body in the body.
