1. Eating fruit after a meal
Many people like to eat fruit after a meal, which is a wrong living habit. After food enters the stomach, it needs 1 to 2 hours to digest. If you eat fruit immediately after a meal, it will be blocked by the food you just ate, preventing the fruit from being digested properly. Over time, this can cause symptoms such as bloating, diarrhea, or constipation. 2. Drinking strong tea after a meal
Drinking tea after a meal will dilute gastric juice and affect the digestion of food. In addition, tea contains a large amount of tannic acid. Drinking tea after a meal will cause undigested protein in the stomach to combine with tannic acid to form indigestible precipitates, affecting protein absorption. Tea can also hinder the absorption of iron elements, and long-term consumption can even lead to iron-deficiency anemia.
3. Smoking after a meal
The harm of smoking after a meal is 10 times greater than usual! This is because the blood circulation in the digestive tract increases after eating, causing a large absorption of harmful components in cigarettes, damaging the liver, brain, and cardiovascular system, and causing diseases in these areas. 4. Bathing after a meal
There is a common saying that "a full stomach bath, an empty stomach shave," which is also an incorrect living habit. After bathing, the blood flow to the body surface increases, and the blood flow to the gastrointestinal tract decreases accordingly, which weakens the digestive function of the stomach and intestines, causing indigestion.
5. Loosening the belt after a meal
Many people feel bloated after overeating and often loosen their belts. Although this makes the stomach more comfortable, it will cause a decrease in intra-abdominal pressure, forcing the stomach to sag. Over time, this can lead to a real condition of gastric ptosis. 6. Walking after a meal
"A hundred steps after a meal" not only cannot help you live to be ninety-nine, but due to the increase in exercise, it affects the absorption of nutrients by the digestive tract. Especially for the elderly, whose heart function is reduced and blood vessels are hardened, post-meal walking often leads to a drop in blood pressure.
7. Singing karaoke after a meal
There is another common saying that "play the flute when full, sing when hungry," which is correct. After a full meal, a person's stomach capacity increases, the stomach wall becomes thinner, and blood flow increases. At this time, singing will cause the diaphragm to move down and increase abdominal pressure, which can cause indigestion in mild cases, and gastrointestinal discomfort and other illnesses in severe cases. 8. Driving after a meal
Drivers who drive immediately after a meal are prone to car accidents. This is because the stomach and intestines need a large amount of blood to digest food after a meal, causing a temporary ischemia of the brain.
