Do you think home is safe? In fact, most people in these "healthy minefields" don't know!

If the refrigerator is not used well, it may become a "poison box" or even a "cancer box"

Refrigerator is one of the important inventions in modern society, which brings a lot of convenience to our daily life. In medicine, there are also data showing that the invention of refrigerator significantly reduced the incidence of gastric cancer-because the problem of food deterioration is no longer serious. But there are also many people who don't fully understand the refrigerator and just believe that it is a "safe". In fact, in recent years, the incidence of gastric cancer and colorectal cancer in China is increasing year by year, and among them, refrigerators are "dereliction of duty".

On holidays, we all think the refrigerator is too important. Just like a safe, it contains everything and can store inexhaustible food. Today, I want to remind everyone that the refrigerator is not a safe! If it is not used well, it may become a "poison box" or even a "cancer box"! Because there are several deadly "minefields" in the refrigerator, you must not touch them.

A set of data abroad shows that the invention of refrigerator reduced the incidence of gastric cancer by 20%, but in recent years, the incidence of gastric cancer and colorectal cancer in China has not decreased, which has a lot to do with improper use of refrigerator. ?

The coke and mineral water we usually drink are fine, but the bottles can't last long. Many people will leave the finished plastic bottles as storage bottles for things like oil and peppers, which is very unhealthy.

The bottom of the plastic bottle is marked with numbers such as "1", "2" and "3", which represent the materials used in the plastic bottle. The most common "1" stands for polyethylene terephthalate (PET), so it's best to treat it as disposable, and don't leave it for oil or seasoning.

People usually don't care much about the material of plastic bottles, so they often use condiments such as oil and pepper in plastic bottles after drinking water. But for health reasons, everyone must look at the numbers at the bottom of plastic bottles. If it is 1, it is best not to reuse it.

Plastic bottles are soft because they are made of plasticizers. Plastic bottles usually contain 16 common plasticizers, such as dihexyl phthalate (DEHP), dibutyl phthalate (DBP) and phenylbutyl phthalate (BBP).

These substances pose considerable health risks. First of all, plasticizers have the risk of causing malignant tumors; Secondly, it will produce chemicals that interfere with biological endocrine, and these substances will cause chronic poisoning effects after entering the human body. It will simulate the natural hormones in the body, combine with hormone receptors, change the number of normal hormones in the human body, make the human body have an excessive effect on hormones, and thus destroy the normal function of the human body. ?

We often say that the change of "environmental hormones" leads to many people's infertility or baby malformation, which is largely caused by improper use of dietary materials.

Our daily life is shrouded in "plasticizer", such as going out to eat, eating leftovers will be packaged, and packaging boxes will be used; Even if you don't go out to eat, open the refrigerator at home, which is also full of plastic products. Here is a cruel case caused by improper use of the packaging box.

Xiao Li, 25, is a chef in a star-rated hotel. Every day after work, he dutifully cooks some dishes and takes them home for his father to eat. Unexpectedly, at the end of 20 14, my father suddenly felt inexplicable pain in his lower abdomen and had poor defecation. In severe cases, he will also discharge black blood clots. A week later, Xiao Li accompanied his father to the hospital for examination, but the result was a bolt from the blue: his father had advanced colorectal cancer.

The reason why Xiao Li's father suffers from colorectal cancer has a lot to do with frequent use of packaging boxes. Packaging boxes are usually disposable. After Xiao Li's father finished eating, if there are leftovers, they should be packed in boxes and kept in the refrigerator. Over time, the plasticizer melted out of the box, and the leftovers themselves also produced carcinogens such as nitrite. The combination of the two slowly breeds malignant tumors in the human body. ?

Therefore, we must pay attention to the cleaning, cooking and storage of daily food. Because each of the above links has the risk of infection with pathogenic factors. Especially in the use of storage boxes, basically only plastic boxes made of No.5 polypropylene are suitable for putting into the refrigerator. This material is relatively stable and resistant to high and low temperatures, and its applicable temperature is -20℃ to 120℃. Therefore, we should remember that only when the numbers "5", "snowflake" or "minus 20 degrees Celsius" are marked on the bottom of plastic products can they be stored in the refrigerator.

Is your plastic wrap suitable for the refrigerator?

Besides plastic bottles and boxes, there is also a common plastic product in our refrigerator. Not very eye-catching, but potentially more harmful, that is, plastic wrap.

Many people think that food must be wrapped in plastic wrap before it can be put into the refrigerator. In fact, many plastic wrap sold in the market are not suitable for putting in the refrigerator.

We did the following experiments on the three most commonly used plastic wrap on the market.

The first one was bought from a fruit stand. From the appearance, it is particularly bright, thin and soft, and it is not easy to ignite. The center of the hot flame is yellow, the edge is green, there is white smoke and softening phenomenon, and the smell of burning can be smelled at the same time. After burning, the plastic wrap is black. ?

The second one is plastic wrap bought from a deli, which looks very bright, and the burning process is similar to the first one.

The third is the plastic wrap purchased from a regular supermarket, which is translucent, hard and easy to ignite. When burning, the upper end of the flame is yellow and the lower end is blue. There is a phenomenon of melting drops, and at the same time you can smell paraffin. After burning, the plastic wrap is as white as a candle.

The first two kinds of plastic wrap are black after burning, and the flame is yellow-green during burning, indicating that they contain chlorine and have a particularly pungent smell, which can basically be judged as PVC plastic wrap. The third kind is tasteless when burning, and the burning process is like dripping wax, which basically proves to be PE plastic wrap.

At present, there are three kinds of plastic wrap on the market: one is polyethylene (PE) plastic wrap, the other is polyvinylidene chloride (PVDC) plastic wrap and the other is polyvinyl chloride (PVC) plastic wrap.

Among them, PE and PVDC are suitable to be put in the refrigerator, and PVC is best not to be put in the refrigerator. The plasticizer inside will precipitate at any time, and even it can penetrate into the packaged food from the plastic wrap at room temperature, which is even more troublesome if it encounters grease.

It should be noted that even the plastic wrap purchased from a regular supermarket is exquisite in use. Usually you have to wait until the dishes are completely cold before you can wrap them in plastic wrap. Otherwise, instead of protecting the vitamin C in vegetables, it will accelerate the loss of vitamin C?

What kind of plastic bottle is the safest?

The numbers in the triangle at the bottom of the plastic bottle indicate their different materials and characteristics.

No. "1": polyethylene terephthalate (PET)

"1" is commonly found at the bottom of mineral water bottles and carbonated beverage bottles. It shows that the heat resistance of PET material is limited, and it is easy to deform at 70℃, which will melt out substances harmful to human body. Experiments show that the plastic bottle marked "1" may release harmful substances such as plasticizers called "environmental killers" after 10 months. Therefore, the plastic bottle marked "1" should not be placed in the car to bask in the sun, nor should it be used to hold daily edible substances such as wine and oil.

Number "2": high density polyethylene (HDPE)

"2" is commonly found in the outer bottles of white medicine bottles, cleaning products and bath products. HDPE is non-toxic and tasteless, its service temperature can reach 100℃, and it has good heat resistance and cold resistance. But it is not suitable to be used as a water cup or as a storage container to store other items. If the cleaning is not thorough, it is best not to recycle it.

Number "3": polyvinyl chloride (PVC)

"3" is commonly found in raincoats, building materials, plastic films and plastic boxes. PVC is cheap and has excellent plasticity, so it is widely used. However, PVC can only resist the heat of 865,438+0℃, and it will produce harmful substances if the temperature is too high, so it is rarely used in food packaging. Moreover, PVC is difficult to clean and easy to remain, so it is best not to recycle it.

Quantity "4": polyethylene (PE)

"4" is common in plastic wrap and plastic film. PE will produce harmful substances at high temperature, which may induce diseases such as breast cancer after food enters the human body. Therefore, it should be emphasized that plastic wrap cannot be heated together in the microwave oven. ?

Quantity "5": polypropylene (PP)

"5" is common in soybean milk bottles, sour milk bottles, fruit juice bottles, microwave lunch boxes and so on. Its melting point is as high as 167℃. It is the only plastic box that can be put into a microwave oven and can be reused after careful cleaning. However, it should be noted that some microwave lunch boxes are made of PP, but the lid is made of other materials, which is not resistant to high temperature, so the lid cannot be put into the microwave with the box.

Quantity "6": polystyrene (PS)

"6" is common in instant noodle boxes and fast food boxes in bowls. Similarly, PS can't be heated by microwave oven, so as to avoid melting out harmful substances due to too high temperature. In addition, PS containing acidic substances (such as orange juice) and alkaline substances will decompose carcinogens. Therefore, avoid using fast food boxes to package hot and acidic foods.

Number "7": Other Category (PC)

"7" is common in kettles, space cups, milk bottles and so on. Department stores often use this kind of water cup as a gift, but it can easily release a harmful substance: bisphenol A, so the PC should not be exposed to the sun directly, and it is best not to heat it when using it.

Correct cleaning method of practical Rubik's cube refrigerator

Every time the refrigerator is used for 1-2 weeks, it is best to carefully scrub the refrigerator liner and shelf fittings for placing food to ensure the cleanliness of the refrigerator environment and avoid the generation of odor. Especially in summer, the refrigerator should be cleaned and disinfected once a week. ?

Refrigerators need to be cleaned frequently in the following aspects:

1. There are more than a dozen microorganisms on the sealing strip on the refrigerator door. The existence of these microorganisms can easily lead to various diseases of the human body. The cleaning method is: wipe the sealing strip with dry cloth soaked in alcohol, and the effect is the best.

2. Always remove the odor in the refrigerator. If the refrigerator is used for a long time and is not cleaned in time, it will have an unpleasant smell, which is caused by the mixed loading of various items in the refrigerator. It is best not to store the goods for more than one month. In addition, after the refrigerator is used for 1-2 weeks, a small amount of detergent can be added to warm water and then wiped with clean water. You can also mix alcohol and water in a ratio of 7: 3 into a solution, pour it into a sprayer, wipe the refrigerator while spraying, and then use an old toothbrush to remove the dirt in the dead corner, which can effectively drive away the odor.

3. Always clean up the leftovers in the refrigerator. It can be said that every refrigerator has leftovers. On the one hand, it is easy to make the items in the refrigerator smell. On the other hand, the refrigerator is not a sterile room, and leftovers are easily eroded by various bacteria. Therefore, the leftovers in the refrigerator should be eaten as soon as possible. Please be sure to heat them before eating. If you like this article, please share it and let more people see it!
