Bananas in the human body can help the brain create a chemical component, serotonin, which stimulates the nervous system, giving people a signal of joy, calmness, and drowsiness, and even analgesic effects. Therefore, bananas are also known as "happy food." American medical experts have found that eating bananas can prevent high blood pressure, because bananas can provide more potassium ions that lower blood pressure, and resist sodium ion pressure and damage blood vessels. They also believe that people who are deficient in potassium can develop dizziness, general weakness and arrhythmia. Because bananas contain a variety of nutrients, they contain low levels of sodium and contain no cholesterol. They can supply various nutrients to the body after eating, and they will not make people fat. Therefore, eating bananas is not only good for the brain, but also prevents nerve fatigue. It also has the effect of moistening the lungs and relieving cough and preventing constipation.
In busy life, more and more people use healthy foods or supplements to supplement the imbalanced diet. Bananas contain almost all of the vitamins and minerals, so bananas can easily ingest a wide range of nutrients. Among them, bananas contain quite a lot of potassium and magnesium. Potassium prevents blood pressure from rising and muscle spasms; magnesium has the effect of eliminating fatigue.
