How does cancer come about? Except for genetic factors, 90% of them are caused by the external environment.
These carcinogens are everywhere, and some of them are even hidden around us, accumulating over time, causing harm to our body, but we can't find it until the body feels uncomfortable. For example, in your kitchen, these carcinogens may be present.
We need cutlery for every meal every day, but we don't know that if we don't choose the utensils well, there is a risk of cancer.
There are many people who choose tableware based on the criteria of beauty, drop resistance, and application, but they often ignore its safety and use scenarios. Come and see if you have any of these poisonous tableware, kill the bowl at home.
1. Melamine bowl
This type of bowl is also known as a lethal bowl. CCTV once exposed that this kind of anti-porcelain bowl, hot water is poured into it, but what we drink is poisonous water that threatens our health.
The peculiarity of this bowl is that it is not as heavy as a real porcelain bowl, but it is also not as light as a plastic bowl, and it is neither plastic nor ceramic, but a kind of melamine.
It can release heavy metals such as lead, and long-term use may also cause heavy metal poisoning.
In 2013, a girl in Guiyang was diagnosed with leukemia, and she had no family history of genetic disease, and finally found out that a big reason for her suffering from this disease was the use of anti-porcelain bowls.
Long-term use of anti-porcelain bowls is harmful to the body, not to mention some unscrupulous manufacturers, in order to save costs and maximize profits, the production of some unqualified anti-porcelain bowls, this kind of bowl spread to the market, whether it is used by adults or children, it will pose a threat to health.
The main ingredient of this bowl is melamine resin, and the main raw materials of melamine resin are melamine and formaldehyde.
Both of these chemicals are toxic substances that can be volatilized at high temperatures.
CCTV has done experiments, pouring hot water into an unqualified melamine bowl, ten minutes later, formaldehyde exceeded the standard by more than six times, everyone knows the harm of formaldehyde to the body, it is a first-class teratogenic carcinogen.
With our naked eyes, it is difficult to see whether the melamine bowl is qualified, so the safest way is to no longer use the melamine bowl.
2. Plastic bowls
The raw materials for making this bowl are all plastics, and there are a total of 7 types of plastic products. Our common PET is generally used as a mineral water bottle, and the slow heating temperature of plastic is 70 °C, so it must be avoided from high temperatures, and it is not recommended to reuse.
There is also PVC, which is generally used for raincoats, water pipes, etc., and there are also plastic bags or plastic films, with a heat-resistant temperature of 81 °C, but this kind of plastic should not come into contact with food.
However, plastic crispers such as PP can be heated, but it is best to remove the lid. Therefore, it is important to distinguish what can be heated, put it in the microwave oven, oven, and what cannot be heated.
Although it is light to hold and more resistant to falling, it is easy to yellow and deform after being used for a long time, and if there is a crack, it is difficult to clean the food residue inside.
3. Stainless steel bowls
The main component of stainless steel is iron. It is more durable and easy to clean, and it is also resistant to falls, and the service life is relatively long. If you look closely, you will find that the stainless steel cutlery we buy will have the words 304 stainless steel written on it.
In fact, food-grade 304 stainless steel is not the same as ordinary 304 stainless steel. The food-grade is in line with the national standard and has been professionally tested, while the ordinary 304 stainless steel has not been tested by the national standard. The most reliable way is to see if there is the words GB4806.9-2016 on the package.
In fact, there are two kinds of food-grade stainless steel, 304 stainless steel can resist the corrosion and oxidation of chemicals, and the standard material of the stainless steel pressure cooker we use is more than 304.
And 316 stainless steel is better, containing 10% nickel, more corrosion-resistant than 304, widely used in medicine, and there is no precipitation of metal ions, which is very safe.
Fourth, ceramic bowls
The ceramic bowls we commonly use are generally glazed from clay fired at high temperatures. Its surface is generally smoother and heavier in the hand.
Another feature of it is that the surface is generally printed with some patterns, but it is worth noting that there is a difference between overglaze and underglaze.
Many people may overlook this when buying bowls, but it is very important. And the brighter the pattern, the more lead it contains.
If it is an overglaze color without a safety and quality inspection book, you must be cautious when buying it again.
If it is some tableware with inferior pigments, toxic substances may be released when heated, which may pose a threat to our health in daily use.
The tableware of underglaze color is generally coated with a layer of transparent glaze on the outside of the pigment and then fired at a high temperature.
This color locks in the transparent medicine and is safer for our daily use. If you can't tell the difference, it is safest to buy pure white or pure light colored tableware without any patterns.
5. Glass bowls
Glass is divided into soda-lime glass, which is generally the material we usually use. There is also crystal glass, high borosilicate glass.
Soda-lime glass is generally heavier when picked up, and it looks thicker and heavier. But it has a disadvantage that it is easy to fry when it is filled with hot water, and it is generally only suitable for holding cold water.
Crystal glass is also divided into two types, leaded and lead-free. Lead-containing ones are easy to cause lead poisoning when used, while lead-free ones are not resistant to low temperatures.
The best for us to use is high borosilicate glass. This type of glass has a better hardness. It is relatively resistant to high temperatures, and can withstand a temperature difference of more than 150 degrees. Even if you pour hot water and then cold water, it won't burst.
In addition to the bowl, we should also pay attention to the use of chopsticks, after all, the disease comes from the mouth. For the sake of our health, there are some chopsticks that are not suitable for long-term use.
For example, bamboo chopsticks. Although it is relatively light and easy to use, the price is also relatively favorable. However, it has a disadvantage that it has good water absorption, so it is easy to cause the formation of Aspergillus flavus, which has a certain carcinogenicity.
If mildew occurs, we can cause chronic poisoning with long-term use. Impaired growth and development, and increases the risk of cancer, especially liver cancer.
Aspergillus flavus likes to hide in moldy chopsticks, moldy chopping boards, moldy food, and it is not easy to remove it. The most appropriate way is to replace the bamboo chopsticks in one to two months, and if the board is moldy or the food is moldy, it should be disposed of in time.
epilogue
When buying cutlery, it's important to do your homework. The people take food as the sky, and food is the first thing. We eat a variety of delicacies on a daily basis, so don't ignore the safety hazards that exist in the tableware.
The quality and safety of tableware will also affect the quality and safety of food to a large extent, and then affect the health of the body. Only when we use the utensils correctly can we ensure a safe diet. In addition to tableware, we should also pay special attention to the small details in our daily life, which may affect our life and health at any time.
