Water will cause cancer after a few days. Adults should drink 7-8 glasses of water every day. If you exercise a lot a day, you will sweat more and drink more water. The following is about how water can cause cancer after a few days. I hope it will help everyone. Welcome to read the reference.
Water will cause cancer after a few days. If boiled water is stored for three days, it will produce nitrite, which will make people dizzy and disgusting after drinking. If stored for a long time, it will combine with amine to form nitrosamines, which will cause people to get gastric cancer, liver cancer and esophageal cancer. Let's see what experts say about the rumored carcinogenic water.
It is exaggerated to say that drinking boiled water after 3 days will cause cancer.
Since there may be nitrite in tap water, there may naturally be nitrite in boiling water, but as long as it is qualified tap water, this amount is almost zero.
Of course, water pollution is another matter.
Therefore, you can't drink boiled water after 3 days, and there will be a lot of nitrite. This statement only exists in theory.
In medicine, cancer refers to a malignant tumor originating from epithelial tissue, which is the most common malignant tumor. Accordingly, malignant tumors originating from mesenchymal tissue are collectively called sarcomas. A few malignant tumors are not named according to the above principles, such as nephroblastoma and malignant teratoma. Generally speaking, "cancer" refers to all malignant tumors.
Tumor is a new organism formed by abnormal proliferation and differentiation of cells in local tissues at the gene level under the action of various tumorigenic factors. Once a new organism is formed, it will not stop growing because of the elimination of the cause. Its growth is not regulated by normal body physiology, but destroys normal tissues and organs, which is especially obvious in malignant tumors. Compared with benign tumors, malignant tumors grow rapidly, are invasive, and are prone to bleeding, necrosis and ulcers. , and often transfer to the distance, leading to emaciation, weakness, anemia, loss of appetite, fever and serious organ function damage, and ultimately lead to the death of patients.
Can water cause cancer for a few days? Can drinking water all night cause cancer?
Overnight water, boiler water and boiled water are actually boiled water, some of which are stored for a long time and some are boiled repeatedly. It is said that there are a lot of nitrite in these waters, which will cause poisoning, even death after losing consciousness, and nitrite will also cause cancer. Long-term storage, long-term boiling and repeated distillation can indeed convert some nitrate in water into nitrite, but the content of nitrate in water itself is very low, so it is impossible to increase nitrate out of thin air by boiling, let alone convert it into nitrite.
As for the statement that nitrite in water causes cancer, it is a bit exaggerated. Nitrite itself does not cause cancer, but only when it is converted into nitrosamines, and the conversion requires many preconditions, not boiled water. Everything is toxic, the key is the dosage. The symptom of online poisoning is food poisoning caused by nitrite, which mostly occurs in catering units or collective canteens and generally leads to poisoning of more than 200 mg. However, there is very little nitrite in the water, even if it is boiled or boiled repeatedly, it is only 100 micrograms per liter. It is said that it takes 1 ton of water to reach the amount of nitrite poisoning.
Can I drink boiled water repeatedly?
Generally speaking, the content of nitrite in this water will be higher. A large amount of nitrite can directly poison people, because nitrite reacts with human blood to produce methemoglobin, which makes blood lose its oxygen-carrying function and makes people suffer from hypoxia poisoning. Although the content of nitrite in boiled water is not so high, when nitrite reaches a certain dose in human body, it has carcinogenic, teratogenic and mutagenic effects, which can seriously endanger human health.
Therefore, try not to boil water repeatedly. It is also best to "burn hot water as you drink it" in the water dispenser, and don't keep it in a state of "heating-insulation" all the time.
What water should I drink?
(1) mineral water
True mineral water is good and has a certain health care function. However, some mineral waters have disproportionate mineral content, which is not necessarily good. In particular, some mineral water is actually artificially added with several mineral trace elements in pure water, which is difficult to ensure the normal proportion of nature and may lack some necessary trace elements. You should choose authentic brand water when drinking.
(2) Pure water (distilled water, space water)
All harmful and harmless substances and elements have been removed. If pure water is used for drinking and cooking, all kinds of trace elements in the water are gone, which may be potentially harmful in the long run. Used to make tea, keep the tea taste good, but not suitable for repeated use. Especially for the elderly and children, it is not suitable for long-term drinking.
(3) filtered tap water
The tap water treated from the waterworks has been monitored for 35 items such as bacteria, but the water from the water pipe network and water tank to the faucet is best filtered by a simple and economical activated carbon purifier.
Pay attention to daily water use. Drain the accumulated water in the water pipe overnight in the morning. Drinking water can be used for several hours (but not more than one day). Aged old water stored for more than 3 days is not suitable for drinking because its molecular structure has not been deformed by impact. Boiling water usually boils for 3 minutes. Don't cook for too long. It is not good to cook or cook for too long. Water that has been boiled repeatedly and stored in a thermos for several days is not suitable for drinking.
Water will cause cancer after a few days. 3 can steaming steamed bread with tap water directly cause cancer?
"Professor xuanwu hospital's article ... no wonder there are more and more people suffering from cancer. When cooking in a pot, be sure to use boiled water or filtered water. Because if tap water is directly used, the tap water contains chlorine, and then after heating,
Because the pot cover is covered and chlorine gas completely covers the food, it is necessary to steam things with boiling water or water filtered with chlorine gas. Because chlorine is carcinogenic ... "
Recently, such a post has been circulated many times and forwarded by many netizens. Many netizens expressed shock at the content described in the post. "I heard that tap water causes cancer for the first time, so be careful when cooking in the future!" Some netizens said in the comments.
Professor Wang Chuanqi's hospital announced that there was no such person.
The net post begins with "Professor xuanwu hospital Qi", but the netizen did not point out who this "Professor Qi" is.
In fact, this post has been circulating for more than a year. When this matter was hotly debated by netizens, the staff of xuanwu hospital affiliated to Capital Medical University once said that there were two experts named Qi in the hospital, one was a vascular surgeon and the other was an endocrinologist, and both doctors were deputy chief physicians. According to hospital investigation, these two doctors have nothing to do with Professor Qi on WeChat.
On July 3rd12065438, the official Weibo of xuanwu hospital issued a statement saying: "Professor xuanwu hospital Qi's post about cooking food, boiling water first" has aroused social concern. After verification, there is no such "Professor Qi" in xuanwu hospital. Xuanwu hospital hereby declares that any information released by unofficial Weibo in xuanwu hospital does not represent xuanwu hospital's views.
Steaming steamed bread with tap water is harmless to human body.
Expert: Steaming steamed bread with tap water is harmless to human body.
Professor Gao Naiyun from the Institute of Water Technology, School of Environmental Science and Engineering, Tongji University told the reporter that there will be some microorganisms in the pipe network during the transportation of tap water, and chlorination disinfection is a means that is basically used in all countries in the world. The principle is that chlorine forms hypochlorous acid in water, which can turn organic matter in water into harmless by-products.
"According to Beijing standards, the residual chlorine content of tap water is below 0.8 mg per liter, which is lower than the standard of Shanghai 1.0 mg." Professor Gao said that the chlorine content of tap water in Beijing should be lower than that at the end of the pipe network.
0, 5 mg per liter, how low is "0.5 mg"? In fact, if the chlorine content in tap water exceeds 0.8 mg per liter, most people can smell the strong chlorine smell with their noses. Not to mention 0.5 mg per liter. "
"Chlorine does cause cancer, but tap water has volatilized after heating, and its content is very low, which is harmless to human body. If you really want to wrap food with volatile chlorine, how much chlorine does it need? " Professor Gao said that on July 1 day, 2065438, China began to implement the new version of the National Hygienic Standard for Drinking Water, and the detection indicators increased from 35 to 106. This also ensures the drinking safety of tap water. Even if the pot for cooking food is sealed, as long as the water quality is qualified, it will not cause harm to the human body.
