Recently, the World Health Organization’s International Agency for Research on Cancer released a research report showing that, according to the current trend of cancer incidence, by 2020, the incidence of cancer worldwide will increase by 50% compared with the present, and the annual number of new cancer patients worldwide will reach 15 million. Cancer is known as the “plague of the 21st century”, its incidence is getting higher and higher, the reason is multi-faceted, bad lifestyle and dietary habits on the production of cancer cells play a “push and help” role. There are many cancer-causing “killers” hidden in our daily life, if you always maintain a healthy lifestyle, pay attention to stay away from these cancer-causing “killers”, this plague may be very difficult to get close to you, which is by no means sensationalized or claptrap. Now the common cancer-causing “killers” in daily life are listed as follows: One of the killers: fried food, high-fat diet In recent years, the prevalence of colon cancer among urban residents has risen very fast, which is mainly related to people’s dietary high-fat tendency, especially “three high and one low” (i.e., high-fat and low-fat diets). This is mainly related to people’s dietary high-fat tendency, especially “three high and one low” (i.e., high fat, high calories, high protein and low fiber), and the more greasy food they eat, the greater the possibility of cancer, especially fried food. Recently, the Ministry of Health has issued an announcement pointing out that it is recommended to avoid as far as possible eating starchy foods that have undergone prolonged high-temperature processing, such as deep-fried potato chips and french fries and all kinds of deep-fried foods. The food is high in acrylamide, which is a carcinogen. Preventive measures: As a matter of fact, no matter what kind of cancer, a healthy and reasonable life diet is important, and so is the prevention of colon cancer. You should exercise properly, maintain a normal body weight, eat less meat, and eat more fruits, vegetables and whole grains, etc. Reasonable diet, adhere to the exercise, eat more fresh vegetables and fruits, is the key to dietary prevention of colon cancer. Killer No. 2: Nitrite Nitrite can cause esophageal cancer and stomach cancer, and it is found in pickled foods. Pickles, salted meat, sauerkraut, etc. contain nitrites. Nitrosamines are nitrate reduced to nitrite and then combined with amines to become a product, and nitrates and nitrites are widely available in pickles, pickles, salted vegetables, salted fish, salted meat, smoked food, so reduce the intake of these foods is conducive to the prevention of cancer. Vegetables contain more nitrates, cooked and placed too long, under the action of bacterial enzymes, nitrates will be reduced to nitrites, and the products of protein decomposition in the stomach, the formation of carcinogenic nitrosamines. People eat these leftovers, easy to induce stomach cancer. In addition, Director Zeng said, people in Guangdong and other coastal areas have the habit of eating shrimp paste, shrimp oil, and the content of amine nitrite salt is also very high, it is worth causing alarm. Preventive measures: you can not leave the vegetables for too long before eating. The results of the study said that the generation of nitrite in stored vegetables increases with longer storage time and higher temperatures. If the vegetables are kept in the refrigerator for cold storage (2℃～6℃), the increase of nitrite is less. However, the nitrite content will still increase after a long time. Therefore, after buying fresh vegetables, should be eaten in time, do not stay too long. Put in the refrigerator storage is also not insurance. In addition, other ways to adjust the diet to prevent stomach cancer are: low-salt diet, which can reduce the intake of nitrates and nitrites. In addition, daily should eat more fresh vegetables and fruits, fruits and vegetables rich in vitamin C can inhibit nitrite and amine binding. Killer No. 3: Aflatoxin Aflatoxin is the culprit of stomach cancer, liver cancer and esophageal cancer, which is produced by the aflatoxin bacteria grown in moldy grains and peanuts. Epidemiological investigations have found that liver cancer occurs more often in warm, humid areas that are prone to aflatoxin growth, especially in areas that consume a lot of corn and peanuts. Aflatoxin is a fungal toxin produced by Aspergillus flavus, which is one of the strongest substances among the chemical carcinogens found so far, mainly damaging the liver and having strong carcinogenic, teratogenic and mutagenic effects, and at present, the International Center for Cancer (ICC) has designated aflatoxin as a cancer-causing agent. According to the survey, China’s high incidence of liver cancer, especially warm and humid south of the Yangtze River, the incidence of liver cancer increased significantly, this is because the local climate is very suitable for the growth of mold, food mold and contamination of aflatoxin phenomenon is more serious. Aflatoxin is chemically stable and can only be destroyed at high temperatures above 280 degrees Celsius. Preventive measures: When you buy peanut oil at home, pay attention to the quality, and at the same time do not buy too much at once. Poor quality contains high levels of aflatoxin, especially in the south, the weather is humid, peanut oil storage time is too long easy to mold. Therefore, the usual storage of food and other food must be kept at a low temperature, ventilation, dry, avoid direct sunlight, do not use plastic bags of food, as far as possible not to hoard food, pay attention to storage to pay attention to the quality of food and preservation period, as far as possible in the preservation of the period of time to consume. Life can be changed to use tea tree oil, olive oil and other vegetable oils. In addition, do not eat moldy, discolored food. Killer 4: Hair Dye In recent years, hair dye has become a fashionable, however, many experts are concerned about the safety of hair dye, hair dye can cause cancer is by no means sensational. The latest research data show that hair dyes can produce a variety of harm to the human body. Prolonged exposure to hair dyes can cause some of the chemicals to combine with certain cells, causing cell mutations that can induce skin cancer, bladder cancer, leukemia, etc., with hair dyes leading to leukemia being more of a problem. The survey of Minnesota cosmetic base in the United States found that 169 kinds of popular hair dyes, of which 150 kinds were found to have carcinogenic effect; the incidence rate of blood disease in the population using hair dyes is significantly higher than that in the population not using hair dyes; the incidence rate of lung cancer in hairdressers is 6 times higher than that of the normal population. In recent years, it is often found that many patients with aplastic anemia and acute and chronic leukemia have a history of hair dyeing. Therefore, it is almost certain that hair dyes are one of the causes of blood diseases. For this reason, medical experts in the United States have used “hair dye leukemia” to single out hair dye-related leukemia, enough to show that the medical community attaches importance to this. Preventive measures: The frequency of hair dyeing should be minimized. If there is a special need to dye your hair, you should use transient hair dyes instead of long-lasting hair dyes. After hair coloring, the scalp and surrounding skin should be washed thoroughly with water to avoid long-term stimulation of residual hair dyes that may cause skin diseases and skin cancer. You should try to choose hair dyes containing natural dyes, and read the instructions carefully before use to understand the ingredients and methods of use. The interval between two hair coloring should be at least 4 weeks or more, made of chemical synthetic dyes color hair dye is best used sparingly. Killer five: kitchen fumes Recently, a five-year epidemiological survey of lung cancer from Shanghai showed that young and middle-aged women exposed to high-temperature fumes when cooking in the kitchen for a long period of time will increase the risk of lung cancer by two to three times. In addition, the harm of oil smoke to the intestinal tract and brain nerves is also more obvious. Often, women generally like to heat cooking oil to high temperatures during daily cooking, frying and stir-frying dishes. Studies have shown that when cooking oil burned to 150 ℃, the glycerol will generate the main component of the fumes acrolein, which has a strong pungent flavor, on the nose, eyes, throat mucosa has a strong stimulation, can cause rhinitis, pharyngolaryngitis, bronchitis and other inhalation tract diseases. In addition, kitchen fumes contain a carcinogen called benzo(a)pyrene, which can lead to chromosome damage in human cells, and long-term inhalation can induce lung tissue cancer. Preventive measures: women should change their cooking habits, do not overheat the frying pan when stir-frying; kitchen hoods must be installed in the kitchen; in the process of cooking, the hood should always be opened; if there is no hood in the kitchen, windows must also be opened to ventilate the kitchen, so that the fumes can be dispersed as soon as possible. In addition, in order to prevent cancer, you can regularly go to the hospital for health checkups, so as to facilitate early detection and early treatment. Killer six: home improvement With a spacious, comfortable new house is the dream of many people pursued throughout their lives, in recent years, people in order to show personalized, but also the use of a variety of materials, the house “dressed” colorful. But they do not know, some substances are quietly poisoning them. According to the director of the China Interior Decoration Association Environmental Monitoring Center, indoor pollution, mainly formaldehyde, benzene, ammonia and radioactive substances of these four pollutants. At present, a variety of man-made panels, adhesives, wallpaper, etc. contain formaldehyde, formaldehyde is recognized worldwide as a potential carcinogen, it stimulates the eyes and the mucous membranes of the inhalation tract, ultimately resulting in abnormalities in the immune function, liver damage, lung damage and the central nervous system is affected, but also can lead to fetal malformations. Benzene mainly comes from glue, paint, coating and adhesive, is a strong carcinogen. People in a short period of time to absorb high concentrations of benzene, there will be central nervous system anesthesia symptoms, light dizziness, headache, nausea, fatigue, blurred consciousness, and in severe cases there will be a coma and even breathing circulatory failure and death. In addition, ammonia and those radioactive substances also have a certain carcinogenic effect. Preventive measures: To prevent the impact of carcinogens on human body in house decoration, the following points can be taken: 1, try to use natural decorative materials in accordance with national standards and. 2, avoid construction in summer, decorate the house with natural decorative materials. 2. Avoid construction in summer, and keep the house well ventilated after the decoration is completed, and it is better to move in after 6 months. 3.Indoors can breed some plants such as aloe vera, hanging orchids, tiger orchids, cacti, etc., which can help degrade the concentration of formaldehyde, benzene and so on. 4, choose to eliminate harmful gases such as decorative deodorants, air purifiers, formaldehyde eliminators, photocatalysts (titanium dioxide), oxygen and so on.
