With the advancement of science and the development of the economy, "health care" has become a hot topic, covering areas such as mental health care, exercise health care, and food health care. However, in daily life, people often fall into some misconceptions. What is discussed here are the things that should not be done for post-meal health care. It is not advisable to smoke immediately
Some people say: "A cigarette after a meal is better than living like a god." In fact, smoking a cigarette after a meal is extremely harmful. According to research, the amount of toxins absorbed from one cigarette after a meal is greater than the sum of ten cigarettes smoked at other times. This is because after a meal, gastrointestinal motility and blood circulation are enhanced, and the body's ability to absorb smoke increases significantly. The harmful substances in cigarettes enter the body more easily than usual, exacerbating the damage to health. At the same time, nicotine in cigarettes affects gastric juice secretion, inhibiting the secretion of trypsin and phosphates, which hinders food digestion. In addition, bile secretion increases after a meal, and smoking makes this even worse. Once in the stomach, it can cause gastritis. It is not advisable to eat fruit immediately
The traditional view is that eating fruit after a meal can aid digestion. However, recent studies have challenged this: fruit eaten after a meal can be blocked by other food in the stomach, and staying there for too long can cause symptoms like bloating and constipation. The scientific way to eat fruit is 2-3 hours after a meal or 1 hour before a meal. It is not advisable to drink strong tea immediately
Tea contains a large amount of tannic acid. When this substance enters the gastrointestinal tract, it can undergo a chemical reaction with proteins in food, forming indigestible solids that hinder the body's absorption of nutrients. Meanwhile, the tannic acid and caffeine in tea can irritate the gastrointestinal tract, affecting the absorption of iron by the gastric mucosa, which can easily lead to iron-deficiency anemia. Drinking strong tea excessively after a meal, especially for people with kidney deficiency and a weak constitution, can easily cause "tea intoxication," with symptoms like palpitations, dizziness, limb weakness, and unsteady standing. It is not advisable to loosen the belt
Some people like to loosen their belts after a meal to relieve the discomfort of being full. This is not a good practice. Loosening the belt after a full meal causes a sudden drop in intra-abdominal pressure, increasing the activity of digestive organs and the load on ligaments. This can intensify intestinal peristalsis, easily leading to intestinal torsion, with symptoms like bloating, abdominal pain, and vomiting. In severe cases, it can lead to necrosis, perforation, or toxic shock due to intestinal obstruction, endangering life. At the same time, loosening the belt after a meal can also induce conditions like ptosis of the stomach, causing abdominal discomfort and dull pain. It is not advisable to take a bath immediately
When bathing, the skin is stimulated by water temperature and the mechanical action of scrubbing, which promotes the dilation of capillaries on the body's surface, accelerates blood circulation, and increases blood flow. This reduces blood flow to the gastrointestinal tract, affecting its digestive function due to insufficient blood supply. If it's a cold bath, the cold stimulus can easily inhibit intestinal peristalsis and the secretion of digestive juices, causing abdominal pain and diarrhea. Furthermore, bathing after a meal can trigger angina and myocardial infarction in patients with coronary heart disease and is even more dangerous for people with high blood lipids, vascular sclerosis, or hypertension. It is not advisable to "walk a hundred steps"
The old fitness maxim, "A walk of a hundred steps after a meal leads to a life of ninety-nine," has been replaced by the new view that one should "sit quietly with eyes closed for half an hour after a meal before engaging in activity." The reason is that after a meal, the stomach is full, and even light exercise can cause vibration to the gastrointestinal tract. At the same time, a post-meal walk diverts blood flow to the muscles, reducing blood supply to the digestive organs and thus affecting digestion. In contrast, sitting quietly with eyes closed for half a half-hour can protect the stomach, aid food digestion, and reduce the risk of conditions like ptosis of the stomach. It is not advisable to study immediately
Engaging in mental activities like reading, writing, reading the newspaper, or thinking immediately after a meal requires significant brainpower. However, after a meal, a large amount of blood is concentrated in the gastrointestinal tract for digestion, causing relative ischemia and hypoxia in the brain. Coupled with the increased oxygen consumption from studying, this can easily lead to fatigue and drowsiness, reducing learning efficiency. Moreover, it is also not conducive to the digestion and absorption of food.
