"Doctor, do I have leukemia?" Mr. Wang, who was in the community, felt very uneasy some time ago.
He had frequent and very severe headaches and nausea, which reminded him of his neighbor's family a few years ago.
It was a very happy family, the couple gave birth to two lovely children together, and life was very good.
One day, however, their youngest son was diagnosed with leukemia, and it wasn't long before another child was told he had the same condition.
This made the couple anxious, and tried every means to treat the two children, but in the process they found that the husband and wife were all sick.
Logically speaking, the disease is not contagious, but the neighbor's family inexplicably contracted the disease, and since then, the neighbor's family has been in endless despair.
The hospital gave Mr. Wang a detailed examination and found that his symptoms were completely caused by overwork.
After learning of Mr. Wang's doubts, the doctor immediately said that the reason why his neighbor was infected was actually affected by formaldehyde.
This substance is particularly common in real life, especially some dishes that everyone loves to eat in autumn and winter, one of which is formaldehyde that exceeds the standard by nearly 400 times. What's going on here?
1. What is leukemia?
In the long development and evolution of human beings, the human body is constantly changing in the passage of time.
With a brilliant mind, humanity was able to stand at the top of the food chain, and with the creation of civilization, it finally ushered in a harmoniously developed society.
However, in this process, human beings are still limited by lifespan, so human beings have vigorously developed medical technology to improve the average life expectancy of human beings, and at the same time fight various diseases for the human body.
Today, with the development of the times, mankind has established a huge and perfect medical system, which is enough to deal with various incurable diseases.
Unfortunately, there are always some diseases that cannot be completely cured in the short term, and some of which are still incurable.
Among some common large-scale diseases, leukemia is the one that has the deepest impact on adolescents, according to statistics, nearly 40,000 people in mainland China will suffer from this type of disease every year.
The pain of this disease lies in the high cost of treatment, the difficulty of treatment and the pain that patients feel during the treatment.
Therefore, many patients are unable to suffer from the disease in the advanced stage, and finally choose the path of suicide.
Leukemia is a malignant clonal disease of hematopoietic stem cells, which is commonly referred to as abnormal hematopoietic function.
The clinical manifestations are infection of varying severity, fever, hemorrhage, and organ enlargement or bone pain.
According to professional doctors, there are many factors in the cause of leukemia, such as genetics, chemistry, radiation, etc., and the most common symptom is fever.
Because the causative factors are very far from people's daily lives, in the past, leukemia other than hereditary diseases were rarely seen.
However, with the development of the times, the cases of leukemia have gradually increased, mainly because some imperceptible causes are hidden in people's daily life, and formaldehyde is one of them.
Second, the hazards of formaldehyde
Formaldehyde is an organic compound, because of its strong adhesion and corrosion and moth-proof effect, it is often used in people's daily life, such as preservatives, disposable paper cups or plastic hard drives.
In 2004, the International Agency for Research on Cancer (IARC) inadvertently discovered that formaldehyde is easy to cause nasopharyngeal cancer, sinus cancer and other diseases in humans.
Because it is able to degrade tumors-inhibiting proteins in the human body and disrupt the repair mechanism of DNA.
Therefore, since then, formaldehyde has been classified as a group I carcinogen, and with further research, it has been found that it can cause leukemia to a certain extent.
Formaldehyde has no color, but it has a very strong pungent odor, and it is easy to be inhaled by the human body when the concentration of formaldehyde in the air is too high.
At that time, the combination of this substance with protein macromolecules in the body will induce type I hypersensitivity reactions, and in severe cases, it may even induce bronchial asthma.
Some people with sensitive skin can also develop skin diseases such as pigmentation and atopic dermatitis.
There is no doubt that the harm of formaldehyde to the human body should not be underestimated, so many people will take certain precautions after understanding the harm of formaldehyde.
However, what many people don't know is that because of the good anti-corrosion effect of formaldehyde, many manufacturers have begun to mix it into the food they eat daily to keep it fresh.
Since it has no color, it is not noticeable when mixed with food, and it is difficult to detect the pungent smell that exists when mixed with the taste of food.
3. Foods containing formaldehyde
If formaldehyde is added in accordance with food and standards, it is true that food can be stored for a longer time, but unfortunately many black-hearted manufacturers often add excessive formaldehyde in order to earn higher profits.
As a result, formaldehyde levels in food are seriously exceeded, and formaldehyde poisoning can occur if individuals use it without knowing it.
In autumn and winter, people often prefer to eat hot food such as hot pot in order to resist the cold, and the indispensable category of hot pot is vermicelli.
When winter comes, the sales of vermicelli will skyrocket, and the ingredients for vermicelli are often sweet potatoes and potatoes with high nutritional value.
However, the shelf life of this raw material is not long, so black-hearted merchants first soaked vermicelli with formaldehyde, so that the shelf life will be improved.
Since then, every year someone has been recruited because of the noodles, and the relevant departments have launched a vigorous search for this, but there are always people who choose to commit crimes against the wind.
The public security department has already tested the seized vermicelli, and was surprised to find that the formaldehyde exceeded the standard by nearly 400 times, and the heavy metal chromium content also exceeded the standard by nearly 200 times.
If the human body uses it for a long time, the risk of leukemia will increase dramatically.
Normally, these manufactured poisonous vermicelli will flow to the market and supermarkets in large quantities, and sellers will often sell these vermicelli at low prices to attract customers to buy them in order to make profits.
The family suffering from leukemia was a big fan of vermicelli and would always buy vermicelli to eat on weekdays, when the hostess of the family saw that the noodles discounted in the supermarket were cheaper.
So I bought a lot of them and went home, thinking about making hot and sour noodles or eating hot pot for my children in autumn and winter, but unknowingly let formaldehyde toxins enter the body, and eventually evolved into leukemia.
In addition to vermicelli, flour sold in the market is also easily adulterated with formaldehyde, and if used unknowingly, it will also pose a serious health hazard.
Fourth, how to choose
There is no doubt that in the face of an endless stream of poisonous vermicelli and substandard food, a single blow cannot make them disappear completely.
Therefore, if you want to use healthy and harmless food, you need to pay special attention to the purchase of food in daily life.
As the saying goes: "cheap is not good", a high-quality product must pay a high cost in the process of production, and the price will definitely not be low when selling for profit considerations.
As mentioned in the article, qualified vermicelli is often made from fresh sweet potatoes and potatoes, so the price when selling is bound to be not low.
Be careful if you come across a discount or a noodle that is significantly lower than the market price.
Because this kind of low-grade vermicelli often has a lot of additives and harmful ingredients added.
Of course, this does not rule out the reason for the impurity of the quality, but this type of vermicelli can be clearly detected from the appearance.
It is understood that vermicelli with excessive undesirable substances is often extremely tough, while high-quality vermicelli will be very easy to break when dry.
Nowadays, most people have a misconception about vermicelli, which is that clear vermicelli tends to be of better quality.
In the process of publicity, merchants will also show transparency as a major advantage of vermicelli, but they don't know that even if the vermicelli made of real materials is fully cooked, it will not be completely transparent.
The same is true for flour, which does not add formaldehyde and will not be pure white, but will be off-white or pale yellow.
Pasta is often easy to deteriorate because it contains moisture, and if it is placed under high temperature conditions for several days without any deterioration, it is not that the product quality is excellent, and it is likely that preservatives such as formaldehyde are added to it.
It is worth mentioning that in addition to the noodles and flour mentioned in the article, many foods in life actually have harmful chemical components.
For example, vegetables and fruits with a long shelf life, because of transportation, in order to ensure the shine of such food, merchants often spray some formaldehyde on the surface.
In addition, there are also quick-frozen foods, which are very popular in daily life because they are convenient and fast.
The longer the shelf life, the more preservatives are added, and quick-frozen foods seem to be stored in a refrigerated way.
In order to make the goods look better, vendors often use caustic soda for treatment, which also invisibly leads to excessive formaldehyde content.
epilogue
To sum up, food safety issues are actually very close to the public's lives, and even the most inconspicuous vermicelli in autumn and winter may have serious formaldehyde exceedances.
The case of leukemia in the article proves how high the harm index of formaldehyde to the human body is.
In the face of these complex foods on the market, how to choose has become a huge problem.
But people don't need to worry too much, as long as they buy from regular channels and are not confused by false advertising and low-price promotions released by merchants, they will definitely be able to buy healthy and safe food.
At the same time, the relevant departments should also intensify their scrutiny, strictly inspect food manufacturing plants, and formulate stricter laws and regulations to restrain illegal businesses.
Only in this way can we eliminate the emergence of harmful products from the root, so as to ensure the food safety and health of the Chinese people.
