Many people are accustomed to having a cup of tea immediately after a meal, thinking that this can promote digestion. In fact, this is not a good habit, it will not only lead to indigestion, but also may increase the risk of suffering from stones, so the folk also have the phrase "drinking tea equals drinking poison after a meal". So what is the reason for this?
First, do not drink tea immediately
"Tea contains tannic acid and theophylline, both of which can affect the body's digestion of food." In an interview with the "Life Times" reporter, the Institute of Pharmaceutical Research said that gastric fluid and intestinal fluid are essential for the human body to digest food. When tannic acid enters the gastrointestinal tract, it inhibits their secretion, leading to indigestion. In addition, tannic acid can also produce coagulation with proteins in foods such as meat, eggs, soy products, dairy products, etc., and form tannic acid protein coagulates that are not easily digested.
Need to be particularly reminded that if you eat foods that contain metal elements, such as iron, magnesium, etc., tannic acid may also react with them, over many years may form stones.
In addition, acidic stomach acid, while the tea is alkaline, drink tea immediately after a meal, theophylline will not only inhibit the secretion of gastric acid, but also dilute the stomach acid, affecting the secretion of gastric acid and other proteases, thereby affecting digestion. The experiments also showed that drinking 15 grams of tea brewed after a meal will reduce the amount of iron absorbed in the food by 50%. The higher the concentration of tea, the greater the harm to the body.
To eat in the restaurant, people do not forget to have cups of tea before the food is served. Li Hongzhu reminded that it is better to drink less tea before meals. If you want to drink, you should choose tea, such as chrysanthemum tea, but remember not to drink tea during the meal, which is more likely to lead to indigestion.
What should we drink after eating? Experts say that boiled water is the best post-prandial drink, which can clear the mouth without affecting digestion. You can drink some light tea after half an hour after a meal.
What else should I do after a meal?
Do not eat fruit after the second meal
Eating fruits after a meal seems to be a hobby of many people, but it is a wrong way of life. Because fruits are rich in monosaccharides, they are usually absorbed in the small intestine. Food eaten after a meal is blocked by food in the stomach. First, it affects the digestion of the food. Second, if it stays too long, monosaccharides will ferment and cause abdominal distension, diarrhea or hyperacidity, constipation and other symptoms.
At the same time, after eating fish and shrimp, it is not advisable to eat grapes and other acidic fruits immediately, because fish, shrimp and other foods contain high protein and calcium, and the fruits containing tannic acid are soon eaten with the same time, easily forming non-digestible substances, causing gastrointestinal problems. Discomfort.
It is best to eat fruit 2 to 3 hours after a meal or 1 hour before a meal. If you eat sausage cooked food, eat some oranges, lemons, there are benefits, because some cooked foods contain sodium nitrite as a preservative, and oranges are rich in vitamin C, can effectively inhibit the synthesis of sodium nitrite, Good for health.
Don't take a shower, don't brush your teeth, don't loose your belt
After taking a bath, the blood flow on the body surface will increase, and the blood flow in the gastrointestinal tract will decrease accordingly, thus weakening the digestive function of the stomach and causing indigestion. Some people like to brush their teeth after a meal, but brushing their teeth immediately can damage loose enamel. In addition, although the loose belt allows the stomach to be comfortable, it will cause a decrease in intra-abdominal pressure, force the stomach to droop, resulting in increased load on the digestive organs and ligaments, promote gastrointestinal motility, prone to bowel torsion, intestinal obstruction, and Lead to stomach sagging and so on.
The fourth best to do sports, not to mention karaoke
Although "a hundred paces after a meal" makes sense, for the elderly, it is best not to exercise because the stomach becomes very heavy due to the acceptance of food within half an hour after a meal. Participating in exercise at this time will cause the stomach to suffer from "turmoil" and impair digestion. After taking a meal, people who have coronary heart disease and myocardial infarction can cause dizziness, fatigue, dizziness, and numbness. Patients with ulcers and drooping stomachs will worsen the condition. After a meal, sit for 30 minutes and move again.
For young people, it is best not to sing after eating, as the saying goes, "Saturate and hungry and sing," because after singing, it will cause the aponeurosis to move down, and the pressure in the abdominal cavity will increase. If it is light, then it will cause indigestion. Intestinal discomfort and other illnesses.
Do not sleep immediately after the fifth meal
Just after dinner, stomach filled with food, digestive function is in motion, then sleep will affect the digestion of the stomach, is not conducive to the absorption of food. At the same time, after the meal, the blood supply to the brain is insufficient. If you go to bed immediately after a meal, it is easy to cause a stroke due to insufficient blood supply to the brain. In addition, after going to sleep, the metabolic rate of the human body is reduced, and it is easy to make the calories contained in the intake food into fat and fatten people.
