As the saying goes, if you walk a hundred steps after dinner, you can live ninety-nine. In fact, this statement is not scientific. In terms of digestive physiological function, the stomach is in a state of filling after meals. At this time, it is necessary to ensure that the gastrointestinal tract has sufficient blood supply for preliminary digestion. Take a proper rest after meals to ensure more blood supply to the gastrointestinal tract.
The disadvantages of taking a hundred steps after dinner
If you take a walk immediately after eating, the blood needs to be transported to other parts of the body, the blood supply of the gastrointestinal tract will be correspondingly reduced, and the food will not be fully digested. Moreover, the digestive juice in the stomach is produced by the conditioned reflex of eating food. Only when the stomach is full can the gastric juice secrete vigorously. For example, after a meal, the stomach wriggles rapidly in the activity, pushing the food that has not been fully digested into the small intestine prematurely, so that the nutrition of the food can not be fully digested and absorbed. Some people are full, but their stomach feels full, but the nutrition is not absorbed into their body, and their bodies are still hungry. At this time, when you get up and leave in a hurry, some of your blood will be concentrated in the exercise system, which will delay the secretion of digestive fluid, destroy the normal digestion of the stomach, and easily induce functional dyspepsia.
Some people cannot walk after meals, such as patients with gastroptosis. These people should not take a walk after meals, and even general walking should be reduced. They can choose to lie flat for 10 minutes after meals. Because the stomach is full of food after meals, then carrying out upright activities will increase the vibration of the stomach, increase the burden of the stomach, and cause or aggravate gastric ptosis. Patients with cardio-cerebrovascular disease should avoid exercise after meals. Because the gastrointestinal activity increases after meals, the blood flow in the gastrointestinal part increases, and the blood flow in the brain decreases accordingly, thus aggravating the disease.
In addition, walking after meals is also bad for patients with coronary heart disease, hypertension, cerebral arteriosclerosis, diabetes, chronic esophageal disease and those who have undergone gastric surgery. It may cause angina pectoris, aggravate dizziness, upper abdominal fullness and discomfort, postural hypotension, premature beats, tachycardia, and paroxysmal atrial fibrillation.
Ways to maintain health after meals
1. Don't eat fruit immediately after meals
Many people like to eat fruit at the end of the meal, and sometimes they also use fruit as dessert, mistakenly thinking that it can relieve the greasy of the dinner. But the fact is that the gut is in the process of digestion after dinner. Eating fruit immediately after dinner will affect the normal digestion of food. The best plan is to eat fruit one hour after dinner.
2. Avoid bathing after meals
Generally speaking, we all know that you can't take a bath when your body is hungry, because it will cause hypoxia and temporary anemia. But can I just take a bath after eating? The fact is that this can't work. Because the blood circulation and energy in the body are concentrated on gastrointestinal digestion after meals, it is easy to cause brain hypoxia.
3. Avoid drinking strong tea after meals
The dinner is too greasy. Drink a cup of strong tea to dissolve the oil. If you really do this, you will be too irresponsible for your health. Not to mention drinking strong tea, drinking water after meals will harm your health, let alone strong tea. Drinking water after meals will dilute gastric juice to a certain extent and directly affect gastrointestinal digestion.
4. Avoid strenuous exercise after meals
There is a folk saying that one hundred steps after a meal can live ninety-nine, which means that proper exercise after a meal can help digestion and is beneficial to human health. However, if you carry out strenuous activities immediately after eating, such as playing ball, running, engaging in heavy physical labor, etc., it will affect the digestion and absorption of food, which is harmful to your health. Because the muscles of the limbs need more blood supply during strenuous exercise or labor, the blood supply of the gastrointestinal tract will be relatively reduced. Digestion and absorption will inevitably be affected. In addition, there is more food in the stomach after meals and the weight is also large. If you exercise or work too hard, it is easy to cause abdominal pain, gastroptosis and other diseases. Therefore, sports or labor should be arranged one hour after meals.
5. Don't go to bed immediately after meals
After eating, because the blood flow of digestive organs increases and the blood supply of brain decreases relatively, people feel tired and even drowsy. This phenomenon is more obvious after lunch. If you go to bed immediately after eating, the peristalsis of the stomach and intestines will slow down, and the secretion of digestive fluid will decrease, and the food will not be fully digested. In particular, children can cause digestive disorders, indigestion and malabsorption, and can cause malnutrition for a long time. Moreover, food stagnation in the stomach will also promote the brain's excitability and make it difficult for people to fall asleep. Even when they fall asleep, they will also bite their teeth, talk in dreams, have nightmares and other stomach discord and lie restless. Therefore, they should wait for a period of time to sleep after meals.
6. Don't loosen your belt after dinner
Many people feel flustered after eating too much, and often loosen the belt buckle. Although their stomachs are comfortable, this will cause a drop in intra-abdominal pressure, forcing the stomach to sag. In the long run, you will really suffer from gastroptosis.
