* 1. The elderly should not be vegetarian for a long time.
The elderly are forbidden to eat vegetarian food because of reduced calorie consumption, loss of appetite, or in order to lose weight and prevent hypertension. This is actually unwise and harmful to physical and mental health. People's aging, hair turning white, tooth loss, osteoporosis and cardiovascular diseases are all related to insufficient manganese intake. Manganese deficiency not only affects bone development, but also causes bone pain, fatigue, hunchback, fracture and other diseases. Lack of manganese can also lead to dull thinking and ineffective feeling. Therefore, the elderly should not be vegetarian. Manganese contained in plant food is difficult to be absorbed by human body, while manganese contained in meat food is less, but it is easy to be used by human body. Therefore, eating meat is an important way to absorb manganese.
*2. The elderly should not sleep immediately after meals.
With the growth of human age, the function of nerve cells is gradually declining. Old people sleep less than young people and wake up easily, so they are prone to fatigue. Old people often doze off during the day and want to sleep, especially after lunch. This practice is harmful to the health of the elderly.
Recently, medical experts in the Federal Republic of Germany pointed out that there are certain dangers for three kinds of people to take a nap after meals: the elderly over 65; Obese people whose weight exceeds 20% of the standard weight; People with extremely low blood pressure or serious disorder of blood circulation system, especially those who often feel dizzy due to narrowing of cerebral vessels. Most elderly people have arteriosclerosis, especially obese people. Hyperlipidemia can easily cause arteriosclerosis of arteries and cerebral arteries, which often leads to insufficient blood supply to the brain. After eating, the blood circulation in digestive tract is vigorous, the blood flow in brain is relatively reduced, and sleep is still, which is easy to aggravate the local blood supply deficiency in brain. There is a health proverb in our country, "Lying down while eating is sick." Therefore, after eating, the elderly should not sleep immediately, but do some light activities to facilitate blood circulation.
*3. Older women should not drink more coffee.
Coffee is a drink, but it may not be suitable for everyone. According to the research of scholars in Washington State University, coffee can reduce the calcium needed by human body by half, thus causing human osteoporosis. Modern medical research believes that people's demand for calcium is increasing gradually in old age, especially for women. Some people have done research and found that premenopausal women need about 1 g of calcium every day, and postmenopausal women need at least 1.5 g every day. However, due to the limited diet of the elderly, calcium deficiency is more common in the body. According to relevant statistics, about 25% of women over 60 suffer from osteoporosis. Therefore, if elderly women like to drink coffee, it will aggravate the lack of calcium in the body, leading to osteoporosis, decreased bone hardness, and a little carelessness in activities, which is prone to fractures.
In addition, older women drinking more coffee will increase the risk of heart disease. Hopkins Medical College in Baltimore, USA, observed 1000 coffee drinkers for 25 years, and found that people who drink five or more cups of coffee every day are twice as likely to suffer from heart disease as those who don't drink coffee.
*4. It is not advisable to eat all dry food for breakfast.
After a night's sleep, people get up in the morning, and their gastrointestinal function has not recovered from the inhibition during night sleep to the excited state, and their digestive function is relatively weak and their appetite is relatively poor. At this time, if you only eat dry food, you will not only eat much, but also be bad for digestion and cannot meet the needs of human activities throughout the morning. In addition, the body also consumes a certain amount of water at night, and it must be supplemented at breakfast to facilitate the normal work of the body. Therefore, breakfast needs to eat some foods containing more water, such as milk, soy milk and other drinks, and it is not advisable to eat all fried dough sticks, bread or biscuits.
*5. It is not advisable to eat only eggs for breakfast.
Some people only eat two eggs for breakfast, which is unscientific. An adult man engaged in moderate-intensity work needs about12,600 kilojoules (3,000 kilocalories) every day, of which breakfast should provide 25-30% of the whole day's calories, about 3137-3,765 kilojoules (750-900 kilocalories), while two eggs only provide a proper amount of calories. Due to insufficient heat supply, the high-quality protein in eggs will be used to make up for the heat and "burn" in the body, which is a great pity.
*6. Excessive drinking and overeating are not recommended for dinner.
Excessive drinking and overeating at dinner and a high-fat diet can induce sudden death at night.
Because drinking, overeating and eating high-fat food for dinner are the main causes of acute pancreatitis. The pancreas is near the stomach and duodenum, which secretes pancreatic juice (including various digestive enzymes) and flows into the duodenum through the bile duct and bile duct. When you are full after a meal, when you lie down and sleep, the full stomach and duodenum oppress the biliary tract and hinder the discharge of pancreatic juice and bile meter. At the same time, excessive drinking and gluttony promote the secretion of pancreatic juice and bile. When the outflow is blocked, pancreatic juice flows back, and trypsinogen enters the interstitial space and is activated by tissue fluid, resulting in self-digestion, which leads to hemorrhagic necrotizing pancreatitis and severe shock, and often dies after being rescued. Therefore, it is not advisable to drink and overeat at dinner, especially for middle-aged and elderly people.
*7. Ginseng royal jelly should not be taken before going to bed.
Ginseng royal jelly should not be taken before going to bed. This is because the blood of middle-aged and elderly people is in hypercoagulable state, and they fall asleep quickly after taking ginseng royal jelly, which slows down the heart rate and aggravates the original blood viscosity, leading to local hemodynamic abnormalities, causing microcirculation disorders and easily promoting cerebral thrombosis. Patients with hypertension, hyperlipidemia and coronary heart disease should not take ginseng royal jelly before going to bed. For patients with ischemic cardiovascular and cerebrovascular diseases, we should pay more attention to taking it 4 hours before going to bed, just like taking antihypertensive drugs to avoid accidents. If you take ginseng royal jelly during the day, you should take it 1 hour after breakfast and 2 hours after lunch.
*8. Smoking is not allowed during meals.
Some people have the habit of stopping for a cigarette while eating and drinking, and then continue to eat and drink, while others simply drink while eating.
Smoking is very harmful to health. Here only talk about the dangers of smoking while eating. Smoking while eating, toxic substances in the smoke will attach to the mouth and throat, and enter the gastrointestinal tract with food, which will directly harm the human body. In addition, smoking can also cause taste disorders, inhibit the secretion of digestive glands, and reduce the resistance of digestive tract mucosa. After a long time, it will inevitably affect people's digestion and absorption function and even cause gastrointestinal diseases. If you smoke while drinking, it is more harmful to your health than simply smoking. Because alcohol can dissolve toxic substances in cigarettes, including carcinogens, and can be directly absorbed by the liver. Therefore, I advise you not to smoke while eating.
*9. Avoid eating more salt before menstruation.
Researchers have found that if you eat a lot of salty food regularly, it will increase the salt and water stored in your body. Eating too much salt before menstruation can easily lead to headaches, swelling, irritability and irritability during menstruation. Therefore, experts pointed out that before menstrual cramps, we should pay attention to eating low-salt, light and fresh food to alleviate the above symptoms.
* 10. Avoid taking vitamins before meals.
After oral administration, vitamins are mainly absorbed through the small intestine. For example, if you take it on an empty stomach before meals, there is no food in the intestine, which is easy to be quickly absorbed into the blood, so that the vitamin concentration in the blood rises rapidly and will be discharged from the urine before being used by body tissues, thus failing to play its due therapeutic role.
Taking vitamin drugs after meals, because there is food in the intestine, vitamins will be gradually absorbed, which is beneficial to its therapeutic effect. In particular, fat-soluble vitamins A, D and E are easily dissolved in fat and absorbed, and should be taken after meals. In addition, vitamins and some minerals also promote absorption each other. For example, calcium helps to absorb vitamin D, and vitamin D also helps to absorb calcium. For example, calcium also contributes to the absorption of vitamin A, and vitamin C contributes to the absorption of iron. These interactions also show that it is more appropriate to take vitamins after meals.
* 1 1. Don't lecture the children while eating.
Many parents often reprimand or beat and scold their children when they know that their children are not studying well or fighting and making trouble outside, which is harmful to their children.
First of all, children eat while crying. When sobbing, rice grains, bread crumbs and water can easily run into the trachea, causing undue pain to children.
Secondly, the child had a big appetite before being reprimanded, but suddenly he was scolded by an adult. Due to strong external stimulation, his appetite may disappear and his saliva secretion will suddenly decrease or even stop. At this time, the children's meals can't be fully mixed with saliva, and the food balls are not lubricated. Especially when eating hard and rough food, it is easy to cut the esophagus, destroy the mucosal layer of gastrointestinal wall and cause serious inflammation.
In addition, when food enters the stomach, it needs to be decomposed into tiny "particles" by digestive juice before it can be absorbed by the intestinal wall. Due to the command of the brain, the digestive system began to secrete digestive juice before eating. If children are reprimanded and beaten by adults, the food they eat in their stomachs will not be completely digested. This not only reduces its absorption rate, but also undigested food will increase the corruption of intestinal food and produce toxic substances, which will cause loss of appetite and diseases. Therefore, don't beat, scold or reprimand children when eating.
* 12. Dieters should not restrict their diet too much.
Obesity is closely related to the occurrence of many diseases, so some obese people are eager to lose weight and eat less. However, restricting diet and losing weight quickly will lead to high cholesterol saturation in bile and easy to form cholesterol stones. It may also be due to rapid weight loss that cholestasis and glycoprotein increase, which promotes the formation of cholesterol crystal core.
Therefore, obese people can't lose weight too quickly. They should reduce their food intake appropriately in a planned way and gradually reduce their weight to an ideal level.
* 13. Don't watch TV while eating.
When people eat, almost all digestive organs are active, digestive juice is secreted in large quantities, and blood is concentrated in the digestive organs. If you watch TV while eating, the brain needs a lot of blood supply, which will affect the activity of digestive organs and hinder the digestion of food. On the other hand, because some blood has flowed into the digestive organs, the blood supply to the brain will be insufficient when watching TV, and it will be dizzy after a long time. As a result, the TV was not good and the food was not good. So, don't watch TV while eating.
* 14. Avoid drinking water before and after meals, and eat it half an hour before and after meals.
It is not advisable to drink water at any time. Some people eat dry steamed bread with water when it is their staple food; Some people always like to drink a cup of strong tea to get rid of greasy food. Some people, especially children, always like to drink water while eating. These are not in line with food hygiene. Because, when eating, people's gastrointestinal organs will secrete digestive juice conditioned reflex, such as saliva secreted by the mouth when teeth chew food, digestive juice secreted by the stomach containing gastric acid and pepsin, etc. , mixed with food scraps. In this way, most nutrients in food are digested into substances that are easily absorbed by the human body. If you drink tea before, during and after meals, it will dilute saliva and gastric juice, weaken the activity of protease, affect digestion and absorption, and be unhealthy for a long time.
If you are very thirsty before meals, you can drink less boiled water or hot soup and have a rest before eating, so as not to affect the digestive function of the stomach.
* 15. Avoid eating cold drinks before and after meals.
Eating cold drinks before meals, due to cold stimulation, causes gastrointestinal capillary contraction, affects the secretion of digestive glands, makes the digestive process insufficient, and affects digestive function for a long time. In addition, the cold drink contains a lot of sucrose, milk, a little cream and water, and starch is also added in the production. Eating cold drinks before meals will raise blood sugar and reduce appetite.
Eating cold drinks after meals will constrict the dilated blood vessels in the stomach and reduce the blood flow, which will hinder the normal digestive process. Cold stimulation accelerates gastrointestinal peristalsis and reduces intestinal absorption of nutrients.
Therefore, cold drinks, sorbets and the like should not be eaten before or after meals, but should be eaten between meals.
* 16. Obese people should not drink more coffee.
Some people think that drinking coffee can not only cheer up, but also "scrape off oil and water", which is beneficial to lose weight. Actually this is a misunderstanding. Because drinking coffee can reduce satiety, but it can stimulate the secretion of gastric juice and improve the digestion and absorption of food, not only can not lose weight, but also make people fat. Therefore, obese people should not drink more coffee.
* 17. It is not advisable to work immediately after meals.
It is not appropriate to work immediately without rest after meals, which will affect your health.
Because after eating, the blood vessels in the gastrointestinal tract dilate, and the blood flowing to the gastrointestinal organs increases, which is beneficial to the digestion and absorption of food. If you work immediately after meals, it will force the blood to meet the needs of motor organs, resulting in insufficient blood supply to the gastrointestinal tract and reduced secretion of digestive juice. Over time, it will also lead to diseases such as indigestion and chronic gastroenteritis. Furthermore, the stomach is full of food after a meal, and it is easy to shake and pull the mesentery at work, which will cause abdominal discomfort, abdominal pain and gastroptosis. Therefore, it is not appropriate to work immediately after meals, and it is best to rest 1 hour before doing it.
* 18. Don't use vitamin C instead of vegetables.
Vitamin C preparations have a wide range of applications. Many people mistakenly think that taking vitamin C preparations has the same effect as eating foods containing vitamin C. In fact, vitamin C contained in natural foods is different from synthetic vitamin C. In fruits and vegetables, natural vitamin C is assisted by ascorbic acid and rutin. Synthetic vitamin C is a pure pharmaceutical preparation, and its effect is far less than that of natural vitamin C. In addition, the dosage of synthetic preparations is often large, and oxalic acid can be formed in the body after long-term administration, which is a potential threat to the formation of renal oxalate stones. On the contrary, vitamin C in fruits and vegetables will not lead to excessive oxalic acid content in urine. Therefore, do not use vitamin C instead of vegetables.
A healthy person needs 50 ~ 150 mg of vitamin C every day. Foods rich in vitamin C in nature include fresh dates, oranges, hawthorn, potherb mustard, peppers, green garlic, tomatoes and many wild fruits and vegetables. Moderate consumption can meet the daily demand of vitamin C.
* 19. Avoid drinking cold water after strenuous exercise.
After strenuous exercise, the body will generate a lot of heat, making the internal organs in a "high fever" state that is much hotter than usual. At this time, if you drink cold water, the throat, esophagus, stomach and other organs will contract sharply when they are cold, which makes people feel uncomfortable. This is what the saying goes, "Blowing the lungs".
Drink cold water after strenuous exercise, especially for temporary pleasure. Drinking a lot of cold water can cause stomach cramps, stomach cramps, and severe syncope, which needs to be sent to hospital for rescue.
Take a rest after exercise, wipe your sweat, take a shower, and then drink warm water. Don't drink too much at a time. It is best to drink light salt water, which can not only quench thirst, but also supplement the salt lost in the body due to perspiration.
*20. It is not advisable to eat more sugar after exercise.
Some people often like to drink some high-concentration sugar water or eat some sweets after exercise, which can relieve fatigue and quench thirst for a while and feel very comfortable. Therefore, people mistakenly think that it is good to eat more sweets after exercise. As for the burnout and loss of appetite caused by this, they don't understand it, but they think it is caused by exercise.
After exercise, if you eat too much sugar and sweets, you need to consume a lot of vitamin B 1 to convert it into energy in your body. So people will feel tired, loss of appetite and so on. And affect the recovery of physical strength. Therefore, it is not advisable to eat more sugar or sweets after exercise.
If you want to eat sweets, you can also take some foods with high vitamin B 1 content, so that you won't feel tired. In daily life, foods containing more vitamin B 1 include vegetables, liver and eggs.
*2 1. It is not advisable to take a bath immediately after a full meal.
Taking a bath immediately after a full meal will affect the digestive function. When taking a bath, the skin blood vessels dilate and the blood flow is strong. If you take a bath immediately after a full meal, the blood flow in the digestive tract will be relatively reduced, and the secretion of digestive juice will be reduced, making the digestive function low. Therefore, it is not advisable to take a bath immediately after a full meal. But it is not advisable to take a bath on an empty stomach, because it is easy to cause hypoglycemia and shock. Therefore, it is most appropriate to take a bath when you are not full or hungry.
*22. It is not advisable to drink tea after meals.
Many people have the habit of drinking tea after leaving their jobs, which is actually not desirable. Because just after eating, the stomach is full of food, and the gastric juice is secreted vigorously. A large number of tea leaves enter the stomach, which will dilute the gastric juice and affect digestion. At the same time, it also increases the burden on the stomach and abdominal pressure, which is not good for the heart. Experts from Georgia Medical College pointed out that drinking strong tea after meals is even more unfavorable. Because tea contains caffeine and tannin, the former will excite nerves and cause insomnia; The latter combines with protein in food in the stomach, which will form indigestible solidified substances and affect the digestion and absorption of protein.
*23. Avoid drinking cold beer before meals.
If you drink cold beer before eating, it is easy to make people's gastrointestinal temperature drop suddenly, blood vessels contract rapidly, and blood flow decreases, thus causing physiological dysfunction and affecting normal eating and food digestion and absorption; At the same time, it will also reduce the secretion of gastric acid, pepsin, small intestine amylase and lipase in human body, leading to digestive dysfunction; Cold stimulation of gastrointestinal tract leads to accelerated peristalsis and dyskinesia. Over time, it is easy to induce abdominal pain, diarrhea and nutritional deficiency.
*24. Don't replace rice with wine for a long time.
A small amount of drinking can promote blood circulation and help to eliminate fatigue. But some people often use wine instead of rice, which is very harmful to human health. According to analysis, 50 grams of liquor contains about 627.6 kilojoules (150 kilocalories) of heat; 250 grams of beer contains about 4 18.4 kilojoules (100 kilocalories), while two small glasses of fruit wine contain more than 4 18.4 kilojoules (100 kilocalories). Therefore, it is not harmful to the human body to skip meals and drink occasionally, especially when drinking, you should eat a lot of vegetables, and you can consume more calories and nutrients. However, if rice is replaced by wine for a long time, it will harm human health. First of all, frequent and heavy drinking can cause alcoholism, cirrhosis, arteriosclerosis, esophageal cancer, gastric cancer and other diseases. Secondly, although drinking can supplement some calories, many nutrients needed by human body, such as various vitamins, minerals and protein, cannot be provided by various wines. Therefore, don't replace rice with wine for a long time, otherwise, the human body will not get all kinds of nutrients needed to maintain the growth, development and physiological functions of various tissues and organs, thus damaging human health.
*25. It is not advisable to eat fruit immediately after meals.
Eating fruit immediately after a meal can easily lead to flatulence, because fruit contains a lot of monosaccharides, which are easily absorbed by the small intestine. If blocked in the stomach, flatulence will occur, leading to constipation. So it is best to eat fruit 2 ~ 3 hours after meals, or 1 hour before meals.
*26. It is not advisable to drink a lot of strong tea after drinking.
Chinese medicine believes that tea has diuretic effect. Drinking some tea after drinking can accelerate alcohol excretion and make people get rid of drunkenness quickly. Therefore, it is reasonable to use tea to relieve alcoholism.
However, drinking a lot of strong tea after drinking also has disadvantages. Because 90% of alcohol is absorbed by the digestive tract and degraded in the liver. In the liver, alcohol is first converted into acetaldehyde by alcohol dehydrogenase, then into acetic acid by acetaldehyde dehydrogenase, and finally decomposed into water and carbon dioxide to be excreted. Generally speaking, this process takes 2 to 4 hours. Moreover, after drinking a lot of strong tea, theophylline in tea can quickly act on the kidney, resulting in diuretic effect. In this way, after alcohol is converted into acetaldehyde, it is discharged from the kidney before it can be decomposed again, which leads to the stimulation of the kidney by a large amount of acetaldehyde and affects the renal function. In addition, drinking too much tea will increase the burden on the heart, especially for people with high blood pressure and heart disease.
Therefore, it is not advisable to drink more strong tea after drinking. You can eat some fruits, such as oranges and apples. If there is no fruit, drinking a glass of juice or sugar water will also help. Of course, the best way is to give up drinking, especially not to get drunk.
*27. It is not advisable to relax your belt after a meal.
If you relax your belt after a meal, the intra-abdominal pressure will decrease, and the activity of digestive organs and the load of ligaments will increase. At this time, it is easy to cause digestive system diseases such as volvulus, intestinal obstruction, gastroptosis and epigastric discomfort. Therefore, it is not advisable to loosen your belt after meals.
*28. Wine should not be drunk with coffee.
Drinking coffee with wine will aggravate the harm of alcohol to human body. This is because alcohol can damage all cells in the human body. After drinking alcohol, alcohol is quickly absorbed by the digestive system and enters the blood circulation system, which further affects the functions of gastrointestinal tract, heart, liver, kidney, brain and endocrine organs, and makes the metabolism of substances in the human body disorder, among which the brain is the most seriously affected, because it can make the cerebral cortex in an overexcited or paralyzed state. Caffeine is the main component of coffee. If eaten properly, it can excite, refresh and strengthen the stomach. Excessive consumption will lead to poisoning. People who drink coffee for a long time, once they stop drinking, will cause high depression in their brains, such as decreased blood pressure and severe headache, and some even have mental abnormalities, such as moodiness, mania and depression.
*29. Don't smoke while drinking.
Smokers tend to smoke more when drinking, which is an extremely bad habit. Because drinking and smoking at the same time have synergistic effects on health, both of them can enhance each other's toxicity. It is known that chemicals such as cyanide, carbon monoxide and benzopyrene in smog have carcinogenic effects. These substances are inhaled into the mouth, nose, throat, trachea and lungs and deposited on the surface of organs in the form of smoke tar. Drinking alcohol can wash away the deposited tobacco tar. Alcohol is a good organic solvent for tobacco tar, which can fully dissolve tobacco tar and facilitate its diffusion into the body through mucosa. In this way, the poison of smoking has increased by a hundredfold. In addition, tobacco poisoning will also make the liver unable to decompose and metabolize alcohol in time, which will aggravate alcoholism. So, don't smoke while drinking.
*30. Don't eat while joking.
Someone sat at the table and started talking, talking a lot. Talking while eating like this will inevitably affect appetite, which is manifested as "eating without knowing the taste"; They often talk too much and eat too little. In the long run, it will inevitably lead to insufficient nutrition and affect health. At the same time, if you talk too much, especially when you are excited, it is easy to mistake rice grains, hard food scraps, bone spurs and so on. Or get stuck in your throat. If you can't choke, it will be very painful. In severe cases, foreign bodies need to be removed through bronchoscope. Therefore, avoid joking when eating.
