Overeating can cause a large amount of gas to be produced in the body, which on one hand加重 the burden on the heart and blood circulation, and on the other hand can cause "flight sickness" such as nausea, vomiting, and airsickness. Therefore, you should not eat too much before boarding the plane. 2、Avoid foods high in fiber and those that easily produce gas.
At high altitudes, due to the decrease in air pressure, gas in the body will expand. If you eat foods high in fiber and those that easily produce gas before boarding, it will worsen the feeling of chest tightness and abdominal bloating. Therefore, before getting on the plane, do not eat the following foods: carbonated drinks, potatoes, dark bread, beans and their products, coarse fiber vegetables (such as lettuce, cucumbers, carrots), etc. 3、Avoid high-fat and high-protein foods.
If you eat greasy, high-fat, and high-protein foods 1.5 to 2 hours before boarding, even if the amount is not large, it will cause the stomach to expand because it is difficult to empty from the stomach. In addition, in the air, gastric juice secretion decreases and gastrointestinal motility weakens, making these high-fat and high-protein foods even harder to digest. This not only causes abdominal bloating and discomfort during the flight, but may also lead to various digestive problems after landing, such as bloating, abdominal pain, and belching.
