wrong diet will harm your health, which is common sense; The wrong behavior after a meal can also harm your health. Surely you don’t know much about it? Take a walk, eat fruit and drink water after dinner These after dinner behaviors are not new to us, and many people regard them as a healthy lifestyle. But in fact, these common after dinner details are actually murdering your health!
◆ eating fruit after meals
harm: it causes abdominal distention, diarrhea or constipation.
after food enters the stomach, it needs to be digested for 1 ~ 2 hours. If you eat fruit immediately after meals, it will be blocked by the previously eaten food, so that the fruit can not be digested normally and it is easy to form flatulence. Because fruits contain many monosaccharides, which are easily absorbed by the small intestine. If they are blocked in the stomach, they will form flatulence and constipation.
suggestion:
fruit is best eaten between meals. In addition to increasing the burden on the stomach and intestines, eating fruit after meals is not a problem for normal people. It should be noted that fruit not only contains vitamins and other nutritional components, but also contains more dietary fiber. Dietary fiber has an impact on the digestion and absorption of some nutrients, such as micro elements. Therefore, it is best to eat fruit between meals. For those with elevated blood sugar, it is not recommended to eat fruit immediately after meals.
◆ hazards of drinking water after meals
: it is easy to cause gastrointestinal diseases
. After drinking water immediately, the intragastric pressure will increase, and the food in the stomach will enter the small intestine without digestion. In addition, diluted gastric juice after drinking water weakens the digestive capacity of gastric juice and is not conducive to gastric acid sterilization.
suggestion:
it is best to drink water on an empty stomach about an hour before a meal, because the digestion of food depends on the digestive juice of digestive organs. Drinking water one hour before meals can ensure sufficient secretion of digestive juice, help digestion and absorption, and do not affect the physiological water content in tissues and cells.
it is better to drink on an empty stomach before breakfast. Because after a night’s sleep, the body loses more water and the blood is more concentrated. Drinking a glass of water after getting up can supplement water, reduce blood viscosity and make blood vessels dilate and recover. Warm water should be used to drink water on an empty stomach, or light drinks such as juice, light tea, vegetable juice, etc. Milk, soybean milk and eggs should not be eaten on an empty stomach, but should be eaten at or after dinner.
◆ walking after meals
harm: indigestion
reason: after a full meal, in order to ensure the digestion and absorption of food, abdominal blood vessels dilate and congest, hundred step walking will affect the absorption of nutrients in the digestive tract due to the increase of exercise.
suggestion:
walking after meals is suitable for people with less activities, long-time desk work, fat body or excessive gastric acid secretion. Don’t walk after dinner. It mainly refers to people with poor physique, weakness and diseases, especially those with gastroptosis. They should lie flat for 10 minutes instead of walking after dinner.
improper physical exercise will also damage the stomach and gallbladder. For example, during strenuous exercise, the blood of the whole body is redistributed, the gastrointestinal peristalsis is weakened, the secretion of various digestive fluids is greatly reduced, and the digestive system is in a state of inhibition; Without proper rest after exercise, eating immediately or greedy for a large number of frozen drinks is easy to cause gastrointestinal diseases and gallbladder diseases such as dyspepsia, abdominal pain, diarrhea and vomiting.
◆ hazards of drinking strong tea after meals
: drinking tea immediately after meals will dilute gastric juice and affect food digestion. At the same time, the tannic acid in tea can turn the protein in food into a non digestible coagulant, increase the burden on the stomach and affect the absorption of protein. Tea contains a lot of tannic acid, which combines with iron in food to prevent iron absorption in the intestine;
* tannic acid is combined with protein to form a tannic acid protein with a convergent effect, which slows down the peristalsis and prolongs the retention time of feces in the intestine. It not only causes constipation but also increases the possibility of human body absorption of toxic substances and carcinogens, so it is not allowed to drink tea immediately after eating, especially not immediately drink strong tea.
◆ go to bed immediately after meals
harm: getting fat.
reason: some office workers often feel sleepy due to satiety after dinner. In addition, they are tired during the day and go to sleep. Sleeping after a full meal will increase the burden on the stomach, hoarding food in the body and causing obesity.
suggestion: rest for at least 20 minutes after dinner before going to bed, even during nap time.
◆ take a bath immediately after meals
harm: indigestion
reason: take a bath after meals, the body surface blood flow will increase, and the blood flow of gastrointestinal tract will decrease accordingly, so as to weaken the digestive function of gastrointestinal tract and cause indigestion.
suggestion: scientifically speaking, don’t wash when you are hungry before meals, which is easy to cause hypoxia and temporary anemia. It’s not good to wash immediately after meals, preferably for an hour or more after meals. Taking a bath before going to bed will eliminate the fatigue of the day and make you sleep easily.
◆ hazards of driving after meals
: it is easy to cause operation errors
after meals, most of the blood is concentrated in the stomach due to the needs of digestion, and the brain is in a state of temporary ischemia. At this time, driving is easy to lead to operation errors and car accidents. Therefore, it is safer to drive an hour after a meal.
◆ smoking after meals
harm: it hurts the respiratory tract and digestive tract
. Some people think that “a cigarette after a meal is better than a living immortal.” In fact, this practice is very harmful to human body. After a meal, the human gastrointestinal peristalsis is very frequent, the blood circulation also speeds up, and the digestive system starts a comprehensive movement.
if you smoke at this time, the absorption of smoke by lungs and whole body tissues will be greatly strengthened, resulting in a large number of harmful components in smoke being absorbed, which will have a strong stimulating effect on respiration and digestive tract, which will undoubtedly bring much greater harm to human function and tissues than usual.
◆ singing karaoke after dinner ok
harm: gastrointestinal discomfort
after eating, the gastric volume increases and the blood flow increases. At this time, singing will move the diaphragm downward and increase the abdominal pressure, which may cause dyspepsia at least, or gastrointestinal discomfort and other symptoms at worst.
therefore, it is best to sing karaoke after normal digestion of food for about 1 hour after dinner, or simply sing first and then eat.
◆ eating cold drinks after meals
hazards: abdominal pain and gastrointestinal spasm
the intestines and stomach are sensitive to ten cold and heat attacks. Therefore, eating cold drinks immediately after meals is very likely to cause gastric spasm, resulting in abdominal pain, diarrhea or indigestion.
◆ exercise immediately after meals
harm: induce stomach disease
within half an hour after meals, the stomach becomes very heavy due to receiving food. At this time, participating in exercise (even slight exercise such as walking) will make the stomach suffer from “turbulence”, affect the digestive function, and even cause stomach disease in the long run.
therefore, it is best to sit for half an hour after dinner, and then go out for light activities such as walking.
◆ desk work after meals
desk work immediately after meals will affect the blood supply of human body to digestive organs and is not conducive to full absorption of nutrition.
◆ read books and newspapers immediately
reading newspapers or thinking after meals will concentrate blood on the brain, resulting in a relative reduction in the blood volume of the digestive system and affecting food digestion.
◆ brush your teeth immediately after meals
otherwise loose enamel will be damaged
◆ attach pants immediately after meals
because attaching pants immediately after meals will suddenly reduce the pressure in the abdominal cavity and weaken the supporting effect of the digestive tract, increase the load of digestive organs and ligaments, aggravate gastrointestinal peristalsis, and prone to intestinal volvulus and intestinal obstruction, And cause gastroptosis.
