Li Ming recently had relatives and friends pass away due to cancer, and while he was sad, he couldn't help but be afraid of when this cancer would be his turn.
No, when he saw the cleaning and delicate cancer article pushed by his mobile phone, he was suddenly scared for a while, and remembered that he had used it for so many years, how much "poison" had to be accumulated?
But when you think about it, if you don't use dish soap, it's really inconvenient. So under the entanglement, he sent a private message to ask Xiao Jiu for help: "Can this dish soap be used, will it cause cancer?"
1. Detergent is a "harmful essence" and is prone to cancer if used for a long time?
As the most common washing tool, dish soap is always available in almost every household, but recently some people say that dish soap can cause cancer, which makes many people shocked and dare not use it again, but is this really the case?
In fact, regarding the health hazards of detergent, the earliest CCTV report has exposed the excessive formaldehyde content of detergent, according to the inspection of relevant departments, it was found that in order to extend the shelf life of the product, unscrupulous merchants added excessive amounts of formaldehyde without permission, and formaldehyde, as a class of carcinogens, has a certain risk of carcinogen, so it has become a saying that "detergent will cause cancer".
So why does dish soap contain formaldehyde?
In fact, formaldehyde can be appropriately added to dish soap, usually used as a "preservative" to extend the shelf life of the product.
"GB 14930.1-2022 National Food Safety Standard Detergent" stipulates that there are two standards for the formaldehyde content of dish soap, Class A dish soap used to clean food, formaldehyde added < 0.05%, Class B used to clean tableware and other containers, formaldehyde content < 0.1%.
Generally, the formaldehyde content is within the range of national regulations, which will not cause serious health risks, and formaldehyde is soluble in water and volatile.
2. Is dish soap residue harmful to human health?
Some people say that when the dish soap runs out, there will definitely be residues on the dishes, and too much use will also affect the human body sooner or later, is this really the case?
In fact, the main ingredient of dish soap is "surfactant", although this ingredient is toxic, but it is also unscientific to say that the dosage is poisonous.
And the human body also has metabolic functions, even if this ingredient will remain in the dishes and chopsticks, ingested by the human body, it will be metabolized quickly, and if you really want to achieve a toxic reaction, you have to take the whole bottle of dish soap to drink it to have an effect.
As for the residue problem, in fact, there are really experts who have done similar experiments, generally after rinsing directly, the residual dish soap has met the specified requirements, the basic residue after the second flush has been lower than the national standard, and the residual amount of dish soap after three rinsing has been 10 times lower than the national standard. So you don't have to worry too much about residues.
Moreover, dish soap can effectively remove E. coli in dishes and chopsticks, reduce the density of flora, and rinse with hot water, which can effectively reduce the number of microorganisms in kitchenware, so dish soap is still very necessary.
However, instead of worrying about the problem of dish soap residue, the following 2 types of dish soap should really be used sparingly:
1. Aromatic dish soap
Generally, this kind of dish soap is added with aromatic chemical pollutants, and the strong smell may cause certain allergic reactions, especially for people with allergies, try to buy less strong fragrance type.
2. Bulk dish soap
Bulk dish soap is generally low in price and very popular in backward areas, but most of this dish soap is a three-no product, the production process is not controlled, and it may contain many added ingredients that are not conducive to human health.
3. These 4 bad habits of washing dishes may be the "accomplice" of cancer
Many people don't believe it, in fact, washing dishes also has a certain degree of exquisiteness, if you don't pay attention to the following details, you may really get sick from the mouth.
1. Soak the dishes and chopsticks for a long time
Soaking dishes and chopsticks for a long time is actually just creating a breeding ground for bacteria, and secondly, the food residue in the used dishes and chopsticks also provides sufficient nutrients for bacteria to multiply, so it is recommended that the dishes and chopsticks should be cleaned and disinfected as soon as possible.
2. The rag is changed from time to time
The Chinese Preventive Medicine Association has done a rag sampling experiment, and found that the number of bacteria per square centimeter of the rag that has not been changed for a long time can reach billions or even tens of billions, and the total number of bacteria around the toilet seat is only 30 million. Not to mention that pathogenic bacteria such as Escherichia coli and Salmonella can also cause a variety of diseases.
3. Wash the dishes and put them on top of each other
Although stacking can reduce the occupation of dishes and chopsticks, this temperature + humidity + unventilated environment is also a favorable place for various pathogenic bacteria to survive. Mould growth can also be accelerated, especially for carcinogens such as aflatoxins.
4. Do not clean the bottom of the bowl when washing dishes
Many people wash dishes without paying attention to the bottom of the bowl, thinking that they don't need to eat at the bottom of the bowl anyway, but have you ever thought that when these dirty bowl bottoms are stacked on top of another bowl, they will also carry bacteria to other bowls, and all dishes should not be overlooked.
Fourth, this carcinogen "lurking" in the kitchen! Many people still don't know it
In 2012 alone, 4.3 million people died from kitchen air pollution, including 34% of strokes, 22% of chronic obstructive pulmonary disease, 26% of ischemic heart disease, and 6% of deaths due to lung cancer.
The Lancet, a well-known British medical journal, has also published a study that points out that kitchen air pollution is the most serious health risk after high blood pressure, smoking and alcoholism.
Wang Xiaojuan, director of the general department of Beijing Chaoyang Hospital and chief physician of the Beijing Institute of Respiratory Diseases, also said that if the kitchen does not have a ventilation system, then inhaling oil fumes for cooking a meal is equivalent to smoking five boxes of tobacco.
In addition to aldehydes, ketones, hydrocarbons, etc., there are also carcinogens such as benzopyrene and nitrosamines, which are harmful to our respiratory system, cardiovascular system, reproductive system, etc.
Therefore, don't ignore the health risks caused by oil smoke, it is best to turn on the exhaust ventilation device when cooking to ensure air circulation, and it is best to cook with less frying.
All in all, the above kitchen hazards must be kept in mind, it is best to choose healthy cooking methods such as steaming and cooking when cooking daily, pay attention to kitchen fume pollution, and manage the hygiene of kitchen utensils to prevent diseases from entering the mouth.
