Driving is tiring, and the human body consumes a lot of calories. These calories mainly come from carbohydrates in food. Bananas have a sugar content of up to 20%, making them an ideal food for replenishing carbohydrates. However, bananas contain a large amount of magnesium. When consumed in large quantities on an empty stomach, blood magnesium levels increase significantly, which can inhibit the cardiovascular system. A change in the magnesium-to-calcium ratio in the body's fluids can lead to symptoms such as significant numbness, muscle paralysis, drowsiness, and fatigue. Driving in this condition最容易发生交通事故。
Foreign traffic police departments once investigated 128 car drivers who were fond of eating bananas. The results showed that 25% of them experienced limb numbness while driving, 33% had drowsiness, and 19% had had traffic accidents. Therefore, you should not eat a large number of bananas on an empty stomach while driving, let alone use them to satisfy hunger.
The fasting blood glucose level for a normal person is 80-120 mg/100 ml. When the blood glucose concentration is below 80 mg/100 ml, some hypoglycemic symptoms appear: hunger, palpitations, hand tremors, dizziness, sweating, irritability, anxiety, and general weakness. Some patients may also experience nausea, vomiting, over-excitement or slow reactions, lack of concentration, and even convulsions and coma. It is very dangerous for a driver to have hypoglycemia. And eating lychees can cause hypoglycemia.
The sugar in bananas is fructose. After this fructose enters the human body, it quickly enters the bloodstream. However, fructose can only be converted into glucose through a series of conversion enzymes in the liver, and then it can be converted into glycogen for storage for the body to use.
If too much fructose enters the bloodstream, the conversion enzymes in the liver may not be able to handle it in time, and fructose will flood the bloodstream and cannot be converted into glucose. A large amount of banana pulp enters the gastrointestinal tract, and the large amount of water in the bananas will dilute the digestive juices, causing loss of appetite and indigestion, leading to temporary hypoglycemia. Therefore, drivers should not eat too many bananas before or while driving.
