The first kind: like to eat hot food, bad living habits will cause cancer. 1In February, 1992, Spanish Tribune magazine reported that it was confirmed by expert investigation that 3 out of every 4 cancer patients were related to bad living habits. According to statistics, among the cancer deaths of people with unhealthy living and eating habits, 35% are related to unhealthy eating habits, 25% are smokers and 3% are drinkers. Some people like to eat hot food, and such people are more likely to develop esophageal cancer. Investigation shows that the northern part of China is the high incidence area of esophageal cancer, and 70%=90% patients like to eat hot food at 70 ℃-88℃. Animal experiments confirmed that after 25 days of continuous perfusion with hot water at 75℃-80℃, the esophageal epithelium of mice proliferated and died, and then obvious precancerous lesions appeared. People in some areas often irritate or cut the esophageal epithelial mucosa when they pass through the esophagus because the food they eat is too rough. Repeated surgical repair can form scars, and over time, malignant transformation can occur on the basis of scars. Statistics show that half of patients with esophageal cancer eat too fast, and 80%-90% of them often eat hard and rough food. They have no habit of chewing slowly. So, don't get into the habit of eating too hot and hard food. Anyone who is used to eating hot and hard food should go to the hospital for examination in time if he has a feeling of choking and lingering cough or pain behind the sternum and upper abdomen recently. The second type: preference for fried and smoked food. Fried and smoked foods are crispy and delicious, and have an attractive appetite. However, some people eat too much and too often, even to the extent of partial eclipse. Eating too much fried and smoked food for a long time is harmful to health. Because high-temperature frying will destroy vitamins A, B, C, E and essential fatty acids in oil. B vitamins lose 40%-50% after frying. The heat energy utilization rate of high temperature treated oil is only 1/2 of that of ordinary oil. Fried food is easy to produce harmful substances when it is fried in high temperature oil pan for a long time. When the frying temperature is lower than 200℃, heterocyclic amines are rarely produced. If the frying temperature exceeds 200℃ and the frying time exceeds 2 minutes, a large number of heterocyclic amines will be formed. Heterocyclic amines enter the human body with fried food, which can damage the liver, delay growth and development, reduce reproductive function and have a strong carcinogenic effect. Repeated use of frying oil will produce free radicals, which are a strong carcinogen. If fried food is fried, the carcinogens produced are very active. Experiments show that gastric ulcer, papilloma, liver cancer, lung cancer, sarcoma and breast cancer are common after feeding rats with oil heated at high temperature for several months. Food will produce carcinogens after being smoked and baked at high temperature. 1966, doctors found that people living in Iceland died of stomach cancer, accounting for more than 50% of all cancer deaths. They eat a lot of smoked food all year round, such as smoked mutton and smoked salmon. Seafarers in Iceland can often eat more fresh food in the harbor, and the incidence of cancer is relatively low. Residents engaged in fishery production along the Baltic Sea often eat smoked fish in large quantities, and the cancer mortality rate reaches 3 18/65438+ 10,000; The cancer mortality rate of residents engaged in agricultural production in this area is only 149/65438+ million, and the cancer mortality rate of digestive tract is 38/65438+ million. Japanese and China's Guiyang Huaxi area, people are also used to eating bacon and smoked fish, and the mortality rate of gastric cancer is high. Smoked fish, roasted rice flour and paste rice flour all contain polycyclic aromatic hydrocarbons. The higher the temperature of smoking, the more they produce. Charcoal baking, pine smoking and electric baking produce different amounts of carcinogens. In a word, we should eat less fried and smoked food. The third type: eating mutton skewers has become a habit. This is a new landscape on the street in recent ten years. There are many customers all year round, which also causes serious environmental pollution, making the streets full of smoke and choking smell, and becoming the pollution source of the city. Some people prefer to eat mutton skewers, and they always buy a few skewers when they pass by the stall after work every day. Eating mutton skewers has become a habit, which is not good for health. Investigation shows that kebabs contain 3,4-benzopyrene. This compound comes into contact with the gastric mucosa after entering the stomach with food, which constitutes a risk factor for gastric cancer. Someone injected 3,4-benzopyrene into animal cortex, causing skin cancer, and injected it into muscle, causing sarcoma. The dose was only 10 mg, and 85% mice developed gastric cancer. Some people use smoked mutton to raise mice, and 5 of 45 mice have malignant tumors. When smoking barbecue, due to the incomplete combustion of charcoal, coal, sawdust and other substances, a large number of polycyclic aromatic hydrocarbons are produced, which pollutes food, and sometimes the content of 3,4-benzopyrene can reach 2. 6 μ g-1 1. 2 μ g/kg. According to the sampling, a kebab can contain 3,4-benzopyrene 1. 03 micrograms -4. 00 micrograms. After 3-4 benzopyrene enters human body, it is transformed into pre-polycyclic aromatic hydrocarbon epoxide under the action of oxidase, which can combine with deoxyribonucleic acid, ribonucleic acid and protein in human cells, making normal cells abnormally cancerous. Some street vendors use bicycle spokes as skewers and wear mutton skewers, which is more harmful to human health. The surface of bicycle spokes is chrome plated. Chromium can be absorbed by mutton skewers under high temperature fumigation. After eating with mutton, chromium accumulates in human tissues and organs, which is harmful to health. According to reports, someone in Britain conducted a survey on painting workers working in aircraft maintenance factories, and found that the incidence of respiratory cancer increased significantly among people who had been exposed to zinc chromate for more than 20 years. Mice inhaled calcium chromate dust once every 35 hours, which can cause pulmonary adenoma after a certain period of time. Therefore, in order to reduce the intake of carcinogen 3,4-benzopyrene, we should eat less smoked and grilled food, eat less or not eat mutton skewers sold on the street, and don't eat mutton skewers roasted with bicycle spokes, so as to avoid the chronic accumulation of these carcinogens in various tissues and systems in the body and gradually lead to the evil consequences of cancer. The fourth kind: superstitious instant noodles. Instant noodles are deeply loved by people because of their convenience. Whether traveling by car or having a simple lunch, instant noodles bring convenience to people. But some people often eat a lot, even to the extent of superstitious instant noodles, which is inappropriate. As a popular food, fried instant noodles have their nutritional limitations, and long-term consumption will lead to malnutrition. The investigation and analysis of scientific research departments show that people who eat instant noodles for a long time are 60% malnourished, 54% iron-deficiency anemia, 20% vitamin B2 deficiency, 23% vitamin A deficiency and 20% zinc deficiency. Eating instant noodles sometimes brings trouble. A nationwide food poisoning incident occurred in Japan, with dozens of victims. The investigation showed that the poisoning was caused by the fact that the edible fried instant noodles were stored at high temperature for a long time and sold after being exposed to strong sunlight, and the oil in them was oxidized and deteriorated, resulting in toxic substances. Scientific research has confirmed that oil reacts with oxygen in the air to produce many harmful substances such as peroxide and epoxide. Stored at high temperature, irradiated by sunlight and ultraviolet rays, when water and other impurities are mixed, the oxidation reaction proceeds rapidly, and the oil oxide is further decomposed into toxic aldehydes and ketones. People will be poisoned if they eat these oxidized fried instant noodles. In addition, the packaging bag of instant noodles is not tightly sealed, cracked and damp, and it is also prone to mildew, deterioration and moth-eaten. If stored or transported improperly, it will be polluted by pathogenic bacteria and poisons, and people eating this instant noodle will also harm their health. Therefore, instant noodles should be bought as you eat, and should not be stored for too long, and they should not be "spicy". It is particularly important to note that instant noodles should not be eaten for a long time, especially for the elderly with digestive dysfunction and children who are growing and developing. Be careful that long-term eating will lead to malnutrition. If it is inconvenient to eat for a long time due to special circumstances, attention should be paid to supplementing high-quality protein, such as lean meat, fresh eggs, aquatic products, seafood, animal offal and other foods rich in protein, vitamins and trace elements. In addition, we should pay attention to eating fresh fruits and vegetables and supplementing enough vitamins and plant cellulose. Special attention should be paid to diet and nutrition. We should not just eat instant noodles, but correct our preferred habits, so that we can enjoy the convenience of instant noodles in our lives and get rich nutrition. ? The fifth type: overeating every day. Every holiday, the table is full of delicious food and wine, which is especially rich. Some people often love wine and food too much, drink too much and eat too much, resulting in the so-called disease of modern civilization-holiday "delicious syndrome". A series of symptoms such as dizziness, dizziness, palpitation, shortness of breath, pulse frequency, elevated blood pressure, numbness of upper limbs, maxillary tremor, etc. suddenly appeared from half to 1 hour after meals. In recent years, the incidence of this modern civilization disease has increased year by year. Tasty syndrome is caused by excessive consumption of delicious food. According to foreign reports, 1000 patients' clinical statistical analysis and physical and chemical examination results show that protein-rich foods such as chicken, duck and fish are transformed into toxic and harmful substances under the action of intestinal bacteria, which can interfere with the political party metabolism of brain nerve cells after reaching the brain with blood flow, so that the physiological function is disordered, resulting in a series of poisoning symptoms. The more you eat this food, the more serious your symptoms will be. To prevent holiday "delicious syndrome", we must pay attention to the following four points: (1) Too greasy cooking: avoid too greasy cooking, use oil in moderation, use oil-rich cooking, such as frying, frying, frying, etc. Use more fuel-efficient cooking methods, such as steaming, stewing, boiling and marinating. (2) Too much meat and too little vegetarian food: When making a menu, we should follow the principle of good meat, good vegetarian food and good combination of vegetarian food. It is forbidden to cook a table full of chickens, ducks, fish and meat. When eating, you should mix meat and vegetables, eat more fresh vegetables rich in cellulose and vitamins, promote gastrointestinal peristalsis and accelerate the discharge of harmful and toxic substances. (3) Eating too much and being too full: Chicken, duck and fish are high in fat and protein, so it is not suitable for spoon-feeding. Eating too much and being too full at one time will make protein decomposition products accumulate in the brain through the blood-brain barrier, which will affect the physiological activities of the brain. (4) Frequent persuasion and binge drinking: It is appropriate for relatives and friends to get together for the raise your glass Festival, but enough is enough. Don't persuade people to drink frequently, drink until they are drunk, and don't compete with each other and drink unconscious. Sixth: Go to work without breakfast. In cities, quite a few people often go to work without breakfast. Doing so for a long time will undoubtedly bring harm to the body. Because, usually in the morning, the work task is heavy, the labor intensity is high, and the energy consumption is relatively large, but the gastrointestinal tract is hungry, leading to lack of energy, physical exhaustion, and even hypoglycemia syncope, leading to accidents. I don't eat breakfast at work, and my fasting time is too long. If you have dinner at 19 the day before and lunch at 12 the next day, the fasting time is as long as 13 hours. During this period, only glycogen released by the liver is decomposed to maintain blood sugar concentration. Due to the physiological activities of various organs in the body, the metabolism of cells and the consumption of physical strength and mental power at work, energy is in a state of deficit, which will damage the function of organs in the long run, and can also produce gallstones and premature aging. 1965, some nutritionists in the United States investigated the breakfast and lifestyle of 6934 elderly men and women over 60 years old, and continued to follow up these elderly people for the next 20 years. The results show that the elderly who insist on eating party breakfast live 20% longer than those who don't. They found a commonality in the elderly over 80 and 90 years old: they insisted on eating a hearty breakfast every day since adolescence. Skipping breakfast is actually a small meal system, which is a two-meal system. Because I am particularly hungry in the morning and eat a lot at noon, the excess heat is converted into fat deposits. If the dinner is rich and oily, because the insulin content in human blood rises to the peak at night, the excess energy is stored, which makes people increasingly fat. A study by American researchers shows that people who skip breakfast have about 33% higher blood cholesterol than those who eat breakfast. Another study shows that people who eat breakfast are less likely to suffer from heart disease than those who don't. Clinically, it is also confirmed that the probability of heart attack is about 1 times higher than that at other times within 2 hours after getting up in the morning. This situation may be related to not eating for a long time. When studying blood viscosity and blood coagulation, they found that people who don't eat breakfast have increased blood viscosity, which makes the blood flow to the heart insufficient, thus easily causing heart attacks. In addition, a special study on women also found that the occurrence of gallstones is closely related to not eating breakfast. Because the fasting time is too long, the bile composition changes, the cholic acid content decreases, and the cholesterol content increases relatively, forming high cholesterol bile. If you don't eat breakfast, over time, the cholesterol in the bile reaches saturation and becomes crystals in the gallbladder, and gallstones can occur.
