Taboos in daily diet
1 Avoid skipping breakfast often.
Some people go to study or work without breakfast or with little food. In the long run, it will not only affect their health, but also reduce their academic or work performance. The brain is the material basis of memory, and all human thinking activities are completed by the brain. The human brain should always have enough oxygen and nutrients to supply. A person's memory is not only related to heredity and environment, but also directly related to the nutritional status of brain cells.
Human memory depends on the cooperation of various substances in the human brain. The more concentrated a person's mind is, the more nutrients he takes in. If it is not replenished in time, more nerve cells will die prematurely, which will affect people's memory. If you don't eat breakfast or eat less breakfast, after 10 am, you will have inattention, rapid heartbeat, bloated head, general weakness, hunger and other situations that affect your study or work. Therefore, we should try our best to create conditions to eat well, eat three meals a day, and ensure the normal development of the body and full of energy.
Avoid eating dry food in the morning.
Since the morning, people's gastrointestinal function has not recovered from the state of inhibition at night, and their digestive function is weak, so it is not easy to digest only by eating dry food. In addition, people consume a lot of water through a night's sleep and should be replenished in time. Therefore, breakfast should be accompanied by dry and thin food, which is not only conducive to the digestion of food, but also helps to replenish water.
Avoid eating while walking.
In order to "buy time", especially in the morning, some people often eat while walking, thinking that this will not only save time, not delay work, but also eat breakfast, which is killing two birds with one stone, but it is a bad habit that does not pay attention to hygiene and is harmful to health. This is because:
(1) People and cars are coming and going on the road, and the dust is flying. Cars emit a lot of harmful substances, all of which float at low altitude. When you eat on the roadside, you will inevitably take in a lot of harmful substances along with the food.
(2) The digestion and absorption of food should be completed under the unified command of the brain. While walking and eating, the brain should not only command the motor system, but also the digestive system. It is not only difficult to digest the food eaten well, but also prone to choking, biting the tongue and foreign bodies entering the tube. Therefore, it is not advisable to eat while walking.
Avoid watching TV while eating.
(1) affects food digestion and nutrient absorption.
When eating, most of the blood in the whole body needs to be concentrated in the digestive system such as the gastrointestinal tract to ensure the completion of the task of digesting food and absorbing nutrients. If you watch TV while eating, your eyes and ears will send signals to your brain, and your brain will constantly analyze, synthesize and judge these signals, and at the same time need more blood to serve your brain. Then, the blood flowing through the gastrointestinal tract is relatively reduced, which will affect the digestion and absorption function.
In addition, watching TV sometimes leads to laughter or arguments, which will delay eating time for a long time, make hot food cold, and at the same time, there will be slurred speech, choking cough, poor chewing and other phenomena. After a long time, the function of digestive organs will be delayed, causing chronic gastrointestinal diseases and affecting nutrient absorption.
(2) It is easy to affect appetite
Hunger is the main cause of appetite, but the color, smell, taste and shape of food can also enhance appetite through conditioned reflex. Watching TV while eating is the main way of life. No matter how delicious the food is, it will lose appetite, which will reduce or disappear the appetite that has already appeared, and even take eating as a burden and make hasty actions to reduce appetite. This is especially true for children, who often put down their bowls and chopsticks when they are half hungry and half full, and malnutrition will occur over time. In order to keep healthy, don't watch TV while eating. It's best to rest after dinner 10 minutes.
Avoid joking when eating.
When people breathe air and eat, there is a common channel, that is, pharyngeal cavity. Air and food enter the trachea and esophagus through the lower part of the pharyngeal cavity. The entrance to the trachea is the larynx, which is the main part of the vocal organs. There is a lobular cartilage in the laryngeal cavity called epiglottis. The stem of epiglottis is fixed on the front inner wall of thyroid cartilage-Adam's apple, and the leaflike part can be lifted up or down.
When talking, singing or laughing, the throat cavity is lifted up, and then it falls down when eating, covering the throat cavity to prevent food from entering the throat. This is an ingenious device to prevent food from entering the trachea by mistake. If you talk, laugh and cry with food in your mouth, your epiglottis will rise, your throat cavity will open, and food will be easily sucked into your throat, trachea and bronchus, resulting in tracheobronchial foreign body disease. Once a foreign body appears in the trachea, it should be discharged to the hospital in time to avoid accidents.
6 avoid eating with a low table or squatting.
Whether eating at a low table or squatting, it does not meet the requirements of physical hygiene. Because the abdomen is squeezed, the gastrointestinal tract cannot move normally, which affects digestion and absorption. Coupled with the compression of abdominal aorta, gastric capillaries can not get enough fresh blood to supplement, which will eventually lead to the decline of digestive function.
7 avoid eating and chewing
Chewing food with one tooth for a long time is medically called "partial chewing". The phenomenon of partial eclipse chewing is more common in children. The main reason is that some children's deciduous molars fall off prematurely. Adults will also develop the habit of partial eclipse chewing because of one side of dental caries or molar loss, or other reasons that make one side of teeth inconvenient to chew.
Long-term partial chewing is harmful. Here, because chewing one side for a long time will make the dentition, clavicle and facial masticatory muscles of this side fully developed, while the other side will be stunted, even emaciated and collapsed, making one face bigger and the other face smaller, thus forming a "crooked face". In addition, tooth dislocation will be caused by the displacement of the lower collar dentition in the chewing direction. Face deflection and tooth dislocation will change the face shape and affect the function of teeth. Therefore, people who have eating and chewing habits should get rid of this habit as soon as possible.
8 avoid eating hot food.
Some people like to drink very hot soup and eat very hot rice, thinking that only in this way can they enjoy the "fragrance" of rice. In fact, this is also an unhealthy eating habit, which is harmful to the mouth, esophagus and stomach. Too hot soup and rice can easily burn the mucosa of the mouth and tongue, and sometimes burn the mucosa of the esophagus. Causing esophageal mucosal necrosis, forming a false membrane and becoming an ulcer after falling off. After this ulcer heals, it will form bruises, which will narrow the esophagus and affect normal eating. This is a kind of esophagitis. People with this disease often feel pain and burning sensation behind the sternum, and sometimes even have symptoms of dysphagia, which can also cause acute simple gastritis.
Eating hot soup and rice often is also related to the occurrence of esophageal cancer. The research shows that in the high incidence area of esophageal cancer, most patients have the habit of eating hot food, and the tolerance temperature of oral cavity, esophagus and gastric mucosa is 50℃~ 60℃. In order to avoid scalding oral cavity and esophageal mucosa and reduce the occurrence of esophagitis, acute gastritis and esophageal cancer, we should develop good eating habits and not eat hot soup and hot rice.
Avoid eating supper before going to bed.
Many people like to eat supper before going to bed, thinking that they can sleep well when they are full. In fact, eating supper before going to bed will affect the sleep effect. Because food can not be fully digested, it is prone to a series of indigestion symptoms such as abdominal distension and stomach pain. At the same time, when sleeping, the stomach is full of food, which will raise the position of diaphragm, limit the activity of lungs, cause the excitement of some central nervous systems in the brain, and make it easy to have nightmares. Dinner should be arranged before bedtime 1 hour, and the food should be easy to digest.
10 Eight Taboos after Meal
(1) Avoid drinking tea immediately.
Some people are used to putting down their rice bowls and drinking tea in teacups after meals, which is really a bad habit that does more harm than good. Because drinking tea can increase the secretion of gastric juice and promote the digestion and absorption of food, especially meat, but tea contains a lot of tannins, which can turn protein in food into indigestible solidified substances, hinder the absorption of nutrients such as protein and iron, and lead to malnutrition over time. People who have the habit of drinking tea after meals may wish to rinse their mouths with tea after meals, which can not only remove oil and relieve boredom, but also clean their teeth and prevent dental caries due to fluoride in tea.
(2) Avoid going to bed immediately
Because the blood flow of digestive organs increases after meals, the blood supply to the brain is relatively reduced, which makes people feel tired and even sleepy. This phenomenon is most obvious after lunch. If you sleep immediately after meals, gastrointestinal peristalsis slows down, digestive juice secretion decreases, and food cannot be fully digested. In particular, infants and young children can cause digestive dysfunction, dyspepsia and absorption disorders, and can cause malnutrition for a long time. And food stagnation in the stomach will also promote the excitability of the brain, making it difficult for people to fall asleep. Even if you fall asleep, you will have the phenomenon of "gnashing your teeth and having nightmares". Therefore, they have to wait for a while after dinner before going to bed.
(3) Avoid eating cold drinks immediately.
Eating cold drinks immediately after meals will produce strong cold stimulation to the digestive tract, causing strong peristalsis of the digestive tract, which may cause abdominal pain and diarrhea. At the same time, the drastic changes of cold and heat will cause the blood vessels in the stomach to contract suddenly, which will lead to the disorder of the digestive function of the stomach in the long run, and even cause indigestion or other diseases.
(4) Avoid strenuous exercise
There is a folk proverb, "Take a hundred steps after a meal and you can live ninety-nine", which means that proper exercise after a meal can help digestion and is beneficial to human health. However, if you engage in strenuous activities immediately after meals, such as playing ball games, running, engaging in heavy physical labor, etc. , will affect the digestion and absorption of food, harmful to the body. Because during strenuous exercise or labor, the muscles of limbs need more blood supply. The blood supply to the gastrointestinal tract will be relatively reduced, and digestion and absorption will inevitably be affected. In addition, there is more food in the stomach after meals, and the weight is also great. If you exercise or overwork, it is easy to cause abdominal pain, gastroptosis and other diseases. So exercise or labor should be arranged after meals 1 hour.
(5) Avoid bathing and swimming immediately.
After a meal, people's digestive system begins to digest and absorb violently, and the blood needed is greatly increased. If you take a bath or swim immediately at this time, the skin blood vessels dilate, the blood flow increases, the blood supply to the digestive tract decreases, and the digestive ability weakens. The whole body exercise during bathing and swimming also promotes the increase of blood flow of various motor organs, which will further weaken the digestive activities of the gastrointestinal tract.
In addition, when swimming, the human body is immersed in water, on the one hand, the pressure of water affects the peristalsis of the stomach and hinders the full mixing of food and gastric juice; On the other hand, abdominal blood vessels stimulated by cold water will cause contraction, resulting in insufficient blood supply to the stomach, which is prone to stomach cramps, vomiting or indigestion. Therefore, take a rest after dinner and before taking a bath 15 minutes, and then go swimming half an hour later. If it is a fierce game, it should be lifted 2 hours after dinner.
(6) Avoid smoking immediately.
People who have a hobby of smoking often say, "A cigarette after a meal is better than a living immortal." In fact, smoking after meals is harmful. According to the determination of relevant personnel, smoking 1 cigarette after meals absorbs more poisons than smoking 10 cigarette at ordinary times. Because after eating, people's gastrointestinal peristalsis is strengthened, blood circulation is accelerated, and the capillaries of the whole body are in a relaxed state. At this time, the human body's ability to absorb smoke is "the best", and toxic substances in smoke are easier to enter the human body than usual, which can aggravate the harm to the human body.
(7) Avoid defecation immediately
Many people have the habit of defecating immediately after meals, which is very harmful to human health. Because the secretion of gastric acid and digestive enzymes increases after eating, the peristalsis function of the stomach is enhanced. If the stool is relieved when the stomach is full of undigested food, the intra-abdominal pressure will suddenly rise, and gastric acid and digestive enzymes may reflux to the esophagus, which may form reflux esophageal ulcer after a long time. After eating hard things, the stool is hard and the abdominal pressure is great. Hard food is easy to damage gastric mucosa and can form erosive chronic gastritis for a long time. Stool immediately after meals can also promote pyloric smooth muscle dysfunction and bile reflux, leading to gastric mucosal congestion, edema and inflammation. Therefore, people who have the habit of defecation immediately after meals should gradually correct it.
(8) Avoid loosening your belt after meals.
As the saying goes, "Relax your belt after dinner, not to mention how carefree you are." It means that after a full meal, the belt is a little tight, relax the belt and feel some "liberation" pleasure in your stomach. But it is unhealthy to do so. Loosening the belt after a meal will reduce the intra-abdominal pressure and weaken the support for the digestive tract. This will lead to an increase in the activity of digestive organs, an increase in the load of ligaments, and an increase in intestinal peristalsis, which will easily lead to intestinal volvulus, abdominal distension, abdominal pain, vomiting, and even diseases such as proctoptosis.
