What are the top ten taboos after meals?

The first thing: it is not advisable to drink tea immediately after meals, which will dilute gastric juice and affect food digestion. At the same time, tannic acid in tea can turn protein in food into indigestible solidified substance, which increases the burden on the stomach and affects the absorption of protein. Tea contains a lot of tannic acid, which combines with iron in food to prevent iron from being absorbed by intestine; Tannic acid and protein combine to form protein tannic acid with astringent effect, which slows down intestinal peristalsis, thus prolonging the retention time of feces in the intestine, which not only easily causes constipation, but also increases the possibility of toxic substances and carcinogens being absorbed by the human body, so it is not advisable to drink tea immediately after meals, especially strong tea immediately. The second thing: it is not advisable to smoke immediately. After meals, the gastrointestinal peristalsis is strengthened, the heat is increased, the organs of the human body are in an excited state, and the blood circulation is accelerated. Smoking at this time, the body's ability to absorb toxic substances in smoke is also the strongest. The third thing: it is not advisable to eat cold drinks immediately. The stomach is sensitive to cold and heat, so eating cold drinks immediately after meals is very likely to cause stomach cramps, leading to abdominal pain, diarrhea or indigestion, especially for the elderly. The fourth thing: it is not advisable to eat fruit immediately. Fruit is rich in monosaccharides, which are usually absorbed in the small intestine, but it is not easy to enter the small intestine immediately after meals and stay in the stomach. Because food enters the stomach, it takes 1-2 hours to be discharged slowly. Fruits eaten immediately after meals will be blocked in the stomach by food. If the residence time is too long, monosaccharide will ferment and cause abdominal distension, diarrhea or hyperacidity, constipation and other symptoms. At the same time, it is not appropriate to eat acidic fruits such as grapes immediately after eating fish and shrimp, because fish and shrimp contain high protein, calcium and other substances, and will soon be eaten with fruits containing tannic acid, which is easy to form indigestible substances and cause gastrointestinal discomfort. It is best to eat fruit 2-3 hours after meals or before meals 1 hour. If you eat intestinal cooked food, it is beneficial to eat some oranges and lemons, because some cooked food products contain sodium nitrite as a preservative, while oranges are rich in vitamin C, which can effectively inhibit the synthesis of sodium nitrite and is beneficial to human health. The fifth thing: it is not advisable to brush your teeth immediately or it will damage the loose enamel. The sixth thing: it is not appropriate to take a bath immediately, which will promote the vasodilation of limbs, and the blood will gather on the body surface, which will reduce the gastrointestinal blood flow, the secretion of digestive juice and the digestive function; If you often take a bath after meals, it will cause gastrointestinal diseases. In addition, it is easy to cause angina pectoris and myocardial infarction in patients with coronary heart disease, especially in patients with hypertension and hyperlipidemia. It is more appropriate to take a bath after meals 1-3 hours. Seventh thing: it is not advisable to take a walk at once. After dinner, my stomach is full. Even a slight exercise will shake the stomach, increase the burden on the gastrointestinal tract and affect the digestive function. There is a lot of blood after dinner. Eighth thing: it is not appropriate to exercise immediately. Within half an hour after a meal, the stomach became very heavy because of receiving food. At this time, taking part in sports (even slight exercise such as walking) will make the stomach suffer from "bumps", affect the digestive function, and even cause stomach problems in the long run. Therefore, it is best for the elderly to sit still for half an hour after meals, and then go out to engage in lightweight activities such as walking. Ninth thing: it is not advisable to lick the belt immediately, because licking the belt immediately after a meal will suddenly reduce the pressure in the abdominal cavity, weaken the supporting role of the digestive tract, increase the load of digestive organs and ligaments, aggravate gastrointestinal peristalsis, and easily lead to volvulus, intestinal obstruction and gastroptosis. The tenth thing: it is not appropriate to work at the desk immediately. Working at a desk immediately after a meal will affect the blood supply of digestive organs, which is not conducive to fully absorbing nutrition. Eleventh thing: it is not appropriate to read books and newspapers immediately or think about problems after meals, which will concentrate blood on the brain, thus leading to a relative decrease in the blood volume of the digestive system and affecting food digestion. Twelfth thing: it is not appropriate to sing karaoke right away. First of all, whether eating at home or in a restaurant, most people want a quiet and comfortable dining environment, and the strong sound stimulation generated by karaoke and the howling of some uncivilized diners have undoubtedly caused mental torture to most guests who eat at the same time. Secondly, after eating, the stomach volume increases, the stomach wall becomes thinner and the blood flow increases. Singing at this time will make the diaphragm move down and increase abdominal pressure, which will cause indigestion and gastrointestinal discomfort. In addition, if you drink alcohol while eating, under the stimulation of alcohol, people's larynx and vocal cords are naturally congested. At this time, karaoke will aggravate the congestion and edema of the larynx and vocal cords, which is easy to cause acute pharyngitis. Therefore, after a big meal, you should have a rest before singing. Thirteenth thing: don't go to bed immediately because you have just eaten, your stomach is full of food and your digestive function is exercising. Sleeping at this time will affect the digestion of your stomach, which is not conducive to the absorption of food. At the same time, there is insufficient blood supply to the brain after meals. 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 sleep, the metabolic rate of human body decreases, and it is easy to convert the heat contained in food into fat, which makes people fat.
