Carcinogens, the word that makes people talk about it, may be closer to yourself than you think.
According to the authoritative classification of the International Agency for Research on Cancer, carcinogens range from category 1 to category 4, and the smaller the level, the greater the harm.
They are not good stubble, there is conclusive evidence that these guys are the most harmful to the human body, and they are worthy of the name "king of cancer", tobacco, asbestos, benzopyrene, aflatoxin, etc., are all impressively listed.
Do you think only these common substances are on the "carcinogenic celebrity list"? That's a big mistake! Many seemingly harmless things are also on this chilling list.
For example, processed meat products, smoked fish, allicin from traditional Chinese medicine, and even wood dust are all classified as Group 1 carcinogens.
It is surprising that these "ordinary" sounding things have a carcinogenic risk no less than that of alcohol and tobacco.
In contrast, Group 2 carcinogens, although slightly lower in level, should not be underestimated.
Among them, there are not only food additives, pesticides and other chemicals, but also acrylamide produced by high-temperature cooking, which may not have direct evidence of carcinogenesis, but animal experiments have sounded the alarm.
As for Group 3 and 4 carcinogens, there is currently a lack of conclusive evidence of carcinogenicity, but it should not be taken lightly.
Caffeine, electromagnetic radiation, etc., are all included in this ranks, and although their harm needs to be further studied, it is always right to be cautious.
Seeing this, I can't help but feel that there are too many carcinogenic risks in life, from diet to environment, from work to hobbies, almost everywhere.
But we don't have to panic too much, and proper prevention and avoidance can minimize the risk.
The number one killer in the diet
When we talk about diet and health, we always think of foods that are nutritious, fresh and delicious.
But some friends may not realize that there are also some "number one killers" lurking in our daily diet, which silently threaten our health and may even lead to the occurrence of cancer.
First of all, there is the "aflatoxin" in moldy food, which is a name that sounds creepy, and its harm should not be underestimated.
Aflatoxins are often found in damp and moldy grains, nuts and other foods, and especially in starch-rich foods such as peanuts and corn.
Once food has become moldy and spoiled, aflatoxins are quietly formed, making it difficult to completely eliminate them even after cooking. What's even more frightening is that a dose of just 1 milligram can cause cancer.
Another "invisible killer" in the diet is the "nitrite" in overly processed foods, some friends may ask, isn't nitrite a commonly used food additive? How did you become a "killer"?
In fact, nitrite itself is not directly carcinogenic, but when it reacts with other substances in the body, it produces nitrosamines, a strong carcinogen.
Nitrite is often used to cure meat products, such as ham and sausages, to extend the shelf life and maintain the color of the meat, and over time, the consumption of these foods may increase the risk of cancer.
If aflatoxins and nitrites are the "invisible killers", then benzopyrene produced by high-temperature cooking is a "blatant" dangerous molecule.
High-temperature cooking methods such as barbecue and frying will cause complex chemical reactions of fats and proteins in food, resulting in the production of carcinogens such as benzopyrene.
Especially those burnt black parts, the benzopyrene content is even more amazing, and often eating these foods is undoubtedly "playing with fire" with cancer.
Seeing this, do you have a deeper understanding of these "killers" in your diet, but understanding is only the first step, and it is more important to learn how to prevent and avoid them.
For example, eating moldy and spoiled food with caution, eating less cured meat products as much as possible, and avoiding excessive heat when cooking, etc., these simple eating habits can help us stay away from the clutches of "cancer killers".
Of course, diet is only one aspect of health, and there are many other cancer-causing risks in life that we need to be wary of.
So, in addition to diet, what are the potential "health killers" in our living environment? In the face of these risks, how can we prevent them?
Formaldehyde is ubiquitous in life
If dietary carcinogens are "invisible killers", then formaldehyde, which is ubiquitous in life, is a "blatant" health threat.
This colorless and odorless gas, often in a seemingly harmless form, lurks in all aspects of our lives, decoration materials and furniture, is the "hardest hit area" of formaldehyde.
Those brand-new cabinets and wardrobes emit the "smell of new furniture" is actually the smell of formaldehyde.
Man-made boards, plywood, adhesives, etc., are the initiators of formaldehyde, and those seemingly environmentally friendly decoration materials, if the quality is not up to standard, may also become the "accomplice" of formaldehyde.
What's more terrifying is that the release period of formaldehyde can be as long as 10-15 years, and the health effects of long-term exposure to such an environment are self-evident.
Clothes, shoes and hats are also the "hiding place" of formaldehyde, those brightly colored and never fade clothes, those structured shoes and hats that are not easy to deform, may have formaldehyde "credit" behind them.
In order to improve the appearance and texture of products, some unscrupulous merchants will use a large number of formaldehyde-containing dyes and styling agents in the production process.
These chemicals can cause harm to human health through skin contact, breathing and inhalation.
Tableware and toys may seem to have nothing to do with formaldehyde, but in fact they may also become "carriers" of formaldehyde.
Some inferior plastic tableware may use formaldehyde-containing raw materials in the production process, and long-term use may lead to the migration and release of formaldehyde.
And those colorful children's toys, if they use formaldehyde-containing paint or glue, can also pose a threat to children's health.
In the face of formaldehyde everywhere in our lives, how can we prevent it? First of all, when decorating, it is necessary to choose high-quality environmentally friendly materials, and try to avoid the use of man-made panels and plywood.
Secondly, when buying clothing, shoes, hats, tableware and other products, you should carefully screen and avoid choosing those suspicious "problem products".
In addition, keeping the room well ventilated and using an air purifier can also effectively reduce the concentration of formaldehyde.
So, what details do you need to pay attention to in daily life to better protect the health of yourself and your family?
Tobacco, alcohol and betel nut, have you been recruited?
When it comes to the risk of cancer, we are always used to looking at the external environment, such as pollution, radiation, etc.
As everyone knows, some seemingly "enjoyable" lifestyle habits may become the "killer" of our health.
Tobacco, alcohol and betel nut are such "invisible killers", they quietly threaten our lives.
Cigarette smoke contains as many as 7,000 chemicals, of which at least 69 are known carcinogens.
Nicotine is one of the "number one killers", this addictive substance will not only directly damage the respiratory tract, but also increase the risk of lung cancer, laryngeal cancer and other cancers by inhibiting immune function.
Alcohol, the "social lubricant", is also an out-and-out "health killer".
Long-term heavy alcohol consumption may not only lead to liver cirrhosis and liver cancer, but also increase the risk of oral cancer, esophageal cancer, breast cancer and other cancers.
Acetaldehyde, a strong carcinogen, is a strong carcinogen that can directly damage DNA and cause cells to become cancerous, while alcohol can also inhibit immune function and reduce the body's ability to fight cancer.
Betel nut, a popular "fashion" in some regions, is actually an accomplice to cancer.
Betel nut fruit contains a variety of carcinogens, such as arecaine, polycyclic aromatic hydrocarbons, etc., long-term chewing of betel nut will cause damage to the oral mucosa and increase the risk of oral cancer.
In the face of the "triple threat" of tobacco, alcohol and betel nut, how to save ourselves? First of all, stay away from tobacco and refuse the temptation of cigarettes.
If you are already a smoker, then make up your mind to quit smoking, take responsibility for your own health, and secondly, limit your alcohol consumption and keep your alcohol intake within a reasonable range.
If you have a tendency to drink heavily, it is important to seek professional help to quit the addiction as soon as possible.
Stay away from betel nut, refuse the temptation of this "fashion", and if you have developed the habit of chewing betel nut, then quit as soon as possible to avoid the risk of oral cancer.
When talking about health threats in modern society, it's hard to avoid a topic of haze.
This "gray killer" hanging over the city has become a lingering nightmare for countless people, and behind the smog, there is an even more terrible "culprit" PM2.5.
The health killer of smog
PM2.5, a term that sounds a bit "high", actually refers to particulate matter in the air with a diameter of 2.5 microns or less.
They are like ubiquitous "invisible killers" in the air, threatening our health at all times.
These tiny particles can easily pass through our respiratory defenses, penetrate deep into the alveoli, and even enter the circulatory system, leading to a range of health problems.
What's even more terrifying is that PM2.5 has been listed as a class I carcinogen by the World Health Organization, and is on the same "carcinogenic blacklist" as tobacco and asbestos.
This means that long-term exposure to PM2.5 pollution will greatly increase our risk of lung cancer, cardiovascular disease, and many other diseases.
In the face of the "deadly threat" of PM2.5, we seem to be somewhat helpless. After all, we can't control the quality of the air, and we can't hide in the "air purification room" whenever and wherever we want.
But that doesn't mean we have to sit back and let PM2.5 run rampant.
As individuals, we can take some protective measures, such as wearing a mask when going out, using an air purifier at home, etc., to reduce PM2.5 inhalation.
We can also reduce PM2.5 production through some lifestyle changes, such as reducing the burning of coal, firewood, etc.
Only through the joint efforts of the whole society can we gradually dispel the haze, let the "invisible killer" of PM2.5 show its original form, and return us to a blue sky.
But no matter how tortuous the road ahead is, we must not give up our yearning for the blue sky and the pursuit of health, which is not only about our own quality of life, but also about the future of the planet we live on.
Let's work hand in hand to move forward towards a fresher and healthier tomorrow!
