Release date: 2015-04-01 The annual April Fool's Day is here again. Looking back on these years, we may have been "stupid" many times by our friends, but these are all good-faith tricks. However, in daily life, there are always people who make malicious rumors to influence people's lives. Today, Xiaobian takes everyone to review the various rumors that have been "stupid" over the years. Let me talk about Xiaobian’s most impressive one: microwave heating food can cause cancer. In fact, according to the review issued by the World Health Organization in 2007, low-frequency household appliances such as induction cookers do not make people sick, and they do not “affect the user’s nervous system, immune system, reproductive system, cardiovascular disease, and even cardiovascular disease. Carcinogenic." The term "electromagnetic pollution" has never appeared in WHO-related literature and materials. Fan Zhihong, an associate professor at the College of Food Science and Nutritional Engineering at China Agricultural University, pointed out that microwaves only heat water molecules in food. The food itself does not undergo chemical changes and does not produce carcinogens. Lu Jianguo, director of the comprehensive inspection department of the National Household Appliance Quality Supervision and Inspection Center, also said that the quality-qualified microwave ovens have undergone rigorous testing and repeated experiments. The microwave leakage and the radiation generated are within the national standard. It will not cause harm to the human body, and will not cause harm through the food it heats. So, what other rumors are there in daily life? First, summarize some rumors related to eating: 1. The most ridiculous "five-second rule" Truth: You can eat it within 5 seconds of eating it. In fact, your food falls to the ground (this is a place full of bacteria) and it will immediately become contaminated with bacteria. 2. Fruit and milk cannot be eaten together Various taboos about drinking milk are widely spread among the people. In a certain TV program, the experts told everyone through the experiment of "pour the orange juice into the milk to produce flocculent sediment". You can't eat sour fruits within 1 hour before and after drinking milk. Truth: Dr. Hu Changli, Ph.D., Key Laboratory of Functional Dairy, China Agricultural University, said that acid precipitation is the basic nature of "casein" in milk. Even if you don't drink it with juice, milk will precipitate in your stomach. Because there is a lot of stomach acid in the stomach, its main component is hydrochloric acid, and the acidity is much more acidic than the fruit acid in the fruit. After the milk enters the gastrointestinal tract, it will first contact the stomach acid and flocculate, and then it will be further digested and absorbed. From another point of view, fruit and milk are good partners, and the nutrition of both is perfect. 3. Stainless steel cups are toxic Tests have shown that after 72 hours of brewing with a stainless steel cup, the cup "corroded". Then the “Expert explained†that the stainless steel contains chromium and will be released into the tea. Because chromium is a toxic heavy metal, it is concluded that "cannot make tea with stainless steel cups, which is toxic." Truth: Dr. Yun, a professor of food engineering at the Department of Agriculture and Biology, Purdue University, USA, said that stainless steel can be bubbled under strong corrosive conditions for a long enough time to show visible corrosion. The tea is nearly neutral, the ionic strength is very low, it is almost non-corrosive, and it is even less likely to cause visible corrosion within a few tens of hours. The biggest possibility is that the tea scale is deposited on the cup and is regarded as "corrosion". In addition, stainless steel will be corroded under certain conditions, and some of the chromium will be dissolved, but the content is extremely small. There is no need to worry about the daily use of stainless steel utensils that meet the national standards. 4. Oxygen-enriched water can “oxygenate†A concept that was played badly abroad was introduced to China. It seems that under the question of science, the grand goal of the manufacturer has been hindered. Truth: Dr. Yun Wuxin said that the first oxygen-rich water is not magical, and the oxygen will be released when the bottle is opened. Secondly, it is not realistic to absorb oxygen by drinking water. Drinking water into the digestive system, although there are "scientists" put forward the theory of "absorbing high concentrations of oxygen in the water through the digestive tract mucosal osmosis", but it has not been recognized by the scientific community. It is theoretically not true to supplement oxygen by drinking water. Finally, the oxygen content in the water is too low compared to breathing. Even if all the oxygen in the oxygen-rich water can be absorbed by the body, the amount is very small compared to the breathing. 5. Mushroom enrichment of heavy metals Previously, an article entitled "Mushrooms Eat Less" was circulated in the WeChat circle. The article said that a doctor from the University of Zurich in Switzerland and researching fungi said that although mushrooms are good, they are heavy metals such as lead and mercury. The enrichment ability is up to more than 100 times. Truth: Professor Xin Xinying from the Institute of Nutrition and Food Hygiene of Shandong University pointed out that compared with certain foods, the ability of mushrooms to enrich heavy metals is indeed high. However, whether the mushroom exceeds the standard of heavy metals is mainly related to its growing environment. Most of the mushrooms currently on the market are grown in the medium prepared by some agricultural and forestry by-products such as cottonseed hulls and bran. Therefore, their chances of exposure to heavy metals are particularly small, let alone heavy metals exceeding the standard. In addition, the mushroom contains a polysaccharide which inhibits the dissociation of heavy metals and makes it impossible to become ions in the body, so it is difficult to be absorbed by the intestines. Therefore, even if people eat mushrooms, the impact on the human body is relatively small. 6. Drink some alcohol during pregnancy, the child is more polite Danish researchers have found that pregnant women who drink a glass of wine a day or a bottle of wine a month are more polite than the pregnant women who don't drink alcohol. Experts from the National Institute of Health and Clinical Excellence (NICE) in the UK also suggested that pregnant women can drink a small glass of wine a day. Truth: There are many other variables in the Danish study that have not been fully considered, and the researchers also said that they are not encouraging pregnant women to drink alcohol. Alcohol can impede fetal development and has a permanent effect on mental and physical growth. Therefore, NICE, the Hong Kong Department of Health and US law do not recommend drinking alcohol for pregnant women, be they beer, spirits or wine. 7. Homemade Medicine: Fruit Enzymes and Lemonade By sealing and fermenting the fruit with sugar, you can create a nutrient-rich fruit enzyme that can be used for beauty, slimming, and detoxification. Some of the ingredients in lemon have an anti-cancer effect 10,000 times more efficient than chemotherapy drugs. You can prevent cancer by drinking with lemon water at home. Truth: “Fruit Enzymes†are just complex mixtures after natural fermentation, with no special health and wellness effects. If the mold is contaminated during fermentation, it may also pose a health risk. Lemon soaking is just a regular drink. The American Association for Cancer Research states that "no food or food ingredient can protect you from cancer." 8. What is the blacklist of foods that cause cancer in the refrigerator? A few days ago, the "blacklist of cancer-causing foods in the refrigerator" circulating on the Internet was on fire again. The list includes bananas, fresh lychee, tomatoes, cucumbers, leafy vegetables, chocolate, ham, bread, fish, leftover moon cakes, Chinese medicine and other common items, causing a large number of users to reprint. Truth: This is also an old rumor. The blacklists listed in the article are just some foods that have been placed in the refrigerator for too long and are prone to spoilage. They do not mention which foods may cause cancer, nor do they explain the scientific basis. Objectively speaking, any food will deteriorate after being left at room temperature for a period of time. Even if it is stored in the refrigerator, it should not be too long. The different types of food mentioned in the “food blacklist†need to be discussed separately. For example, fruits and vegetables, "deterioration" are also divided into two types, one is the chemical change in the low temperature environment of the refrigerator, and the other is "mildew". Only the decayed vegetables that are invaded by mold will reduce the nitrates to nitrite and endanger human health. The meat is better preserved in the case of sterilization and low temperature. If the taste is worse, it is only the wrong method or the time is too long, and it has nothing to do with carcinogenesis. Starch aging may occur in refrigerated moon cakes, but this is a process in which starch molecules are rearranged and has nothing to do with carcinogenesis. However, there are too many types of traditional Chinese medicines, and the storage methods should be in accordance with the doctor's advice, and it is impossible to generalize. The full text of the "blacklist of carcinogenic foods" is summed up, but it is just a "degenerate thing" that can not eat this unusual concept. 9. Light salt water soaked fruits and vegetables can wash off pesticide residues Many people always like to add some salt when washing vegetables and fruits. They think that salt can be sterilized, and naturally remove pesticides from the skin. Some merchants have also introduced fruit and vegetable washing salts. Is this useful? Truth: Salt is the king of the taste, the most commonly used condiment. Salt also has an insecticidal effect, which can kill mollusks (insects) with mucus, such as cockroaches, snails and leeches. However, there is no scientific basis for the statement that “salt water can effectively eliminate pesticidesâ€. Because the chemical composition of the salt is relatively stable and it is not easy to react with other chemical components, even if a certain amount of salt is added to the water to soak the fruits and vegetables, the main effect is water. 10. Vitamin B12 increases liver and kidney burden Some media sent a variety of functional drinks, found that "Dongpeng special drink and other functional drinks in the vitamin B12 content exceeds the daily intake of appropriate", so "vitamin B12 excess will increase the burden of liver and kidney" issued on the grounds Drink more "expert reminders." The truth: whether a functional drink can drink or drink is another problem, but "vitamin B12 excess will increase the burden of liver and kidney" is completely wrong. Generally speaking, “excessive harmful†means exceeding the “maximum intakeâ€, but vitamin B12 does not have this limit. In the news, the “appropriate intake†is regarded as “excessiveâ€, and the concept is completely wrong. The so-called “increased burden of liver and kidney†is also a crime to be added. Rumors directly related to disease 1. Antibiotics can kill the virus Antibiotics kill bacteria, not viruses. The more we rely on antibiotics to treat cold or flu symptoms, the more likely we are to have more problems because other common bacteria can develop resistance. This will lead to the emergence of "superbugs" that will make the condition you want to cure worse. Indeed, every year doctors will prescribe millions of antibiotics, because sometimes it takes a long time to wait for the test results, but more because the patient or the patient’s aunt is arguing for the doctor to do so. Fang Zi is only relying on this hidden "myth". 2. Is a measles vaccine vaccinated for life? At the end of January 2015, a message that “half of a man in a building in Beijing had measles†quickly spread, causing many citizens to worry, even dare not go out, but many people believe that they have been vaccinated for lifelong immunization, no need to vaccinate again. . What are these misunderstandings? Truth: Measles is a common acute respiratory infection, and it is a high incidence in winter and spring. Because measles is highly contagious, viruses can spread easily in environments where people are crowded and air is not circulating. But in fact, the measles virus is not very resistant in the external environment, and it is not resistant to dryness, sunlight, high temperature and general disinfectants. It loses its vitality in the sun or in an air circulation environment for half an hour, survives only 2 hours at room temperature, and is destroyed at 30 °C at 56 °C. It is cold-resistant and not afraid of freezing, so it always comes out in winter and spring. Vaccination is still the most effective measure to prevent measles. Moreover, the measles vaccine is not lifelong immunization. After vaccination against measles, antibodies will appear in the blood for the first 12 days. At 1 month, the antibody peaks. After 2 to 6 months, the antibodies in the blood gradually decrease, but they remain at a certain level, so that people do not get measles. This antibody generally lasts for 10 to 12 years and will drop to negative every year. Some children disappear after 4 to 6 years. After the disappearance of the antibody, the population becomes a new susceptible population. At this time, clinical measles can occur once it is in contact with the measles virus. Therefore, the Department of Disease Control recommends that adults under the age of 40 who have not been vaccinated against measles within five years may be considered for vaccination against measles during the outbreak. 3, a lot of perspiration can prevent cancer Marathon runners don't get cancer because they sweat a lot. Dr. Ernst found that while the athletes discharged a lot of sweat from the body, they also excreted the carcinogenic heavy metals accumulated in the body to completely eliminate the root causes of cancer. Truth: Carcinogenic factors include genetics, environmental pollution, lifestyle habits, etc. Although perspiration can discharge some heavy metals, it is not enough to play an "anti-cancer" role. In addition, marathon runners will also get cancer, and their risk of malignant melanoma and non-melanoma skin cancer will be even higher than the average person. In fact, there are many rumors about cancer, including "acidic foods" that cause cancer, cancer cells that love sweets, cancer is a fungus, people who treat cancer with baking soda, and who die from cancer treatment have more people than those who die directly from cancer. Cancer is a modern disease caused by humans and so on.
