Quickly transfer this message to the family group for the family to see:
The American Medical Doctor Association has found the reasons for the high incidence of leukemia and cancer, mainly for these 3 reasons: 1. Hot drinks in plastic cups; 2. Hot food in plastic bags/boxes; 3. Put the plastic container into the microwave oven and heat it.
Remember: When plastic comes into contact with heat,
Produces chemicals that cause 52 types of cancer
, Never use plastic boxes again! Inform your loved ones and friends to protect them from cancer. ”
Looking at the news that the family group was forwarded, Xiao Liu felt that he was eating spicy hot takeaway suddenly not fragrant, he was usually alone, and he didn’t have time to cook, basically ordered takeaway, then he ate like this every day, isn’t it all cancer…
In fact, if you look closely, you can find that there are a variety of plastic products in our daily life, not only takeaway boxes, but also plastic bags, plastic bottles, etc., are these plastic products really safe? Will it cause cancer?
First, the high incidence of cancer in China is because of the commonly used plastic containers for food?
Plastic bowls, plastic plates, plastic water cups, plastic lunch boxes… When it comes to eating, plastic cutlery is everywhere.
When we walk into the supermarket, we can also see fresh food, cooking oil, vegetables, rice and noodle cooked food, etc., basically using plastic packaging. There is no doubt that plastic containers have long permeated our lives.
Plastic packaging has:
Resistance to permeability, UV resistance, freezing resistance, heat resistance
It can be said that in terms of food preservation, there is no more “cost-effective” material.
It is not only moisture-proof, anti-oxidation, prevents food extrusion and deformation, but also prolongs the shelf life of food and is easy to carry.
So is plastic safe?
It has been reported that plasticizers of polyvinyl chloride (PVC) in plastics are harmful to humans. But then after experiments, it was found that
There is insufficient evidence of harm to humans
。
At present, there is not a single case of poisoning caused by daily plastic products in the world. All the regular plastics on the market,
The presence of harmful substances is very low
, normal use will not reach the human poisoning dose.
It can be said that as long as it is a regular qualified plastic product, everyone can use it with confidence.
Second, the study found that the harm of glass bottles is 4 times that of plastic bottles
The packaging of commonly used items in our lives mainly includes plastic bottles, glass bottles, cartons and cans… In the consciousness of many people, they think that plastic will pollute the environment and be harmful to the human body. But after the evaluation of scientists, it was found that
In fact, glass bottles are the most harmful
The large-scale use of plastic improves the convenience of human life, but because its chemical stability is too good, when handling plastic packaging,
It creates a burden of “digestion” on nature
When plastic bottles are mixed in the soil, it will harden the soil and lead to reduced crop yield; When plastic waste is mixed into land or water, it may be swallowed by animals, resulting in biological death; Microplastics remaining in the ocean may also end up in the food chain.
So what if glass replaces plastic? Scientists have found that glass bottles are 4 times more harmful than plastic.
First of all, the molecules of glass are more complex and require a lot of minerals and chemical synthesis, which is quite damaging to the ecological environment.
Secondly, harmful substances such as lead, fluorine, and arsenic in glass raw materials will be inhaled into the human body when they volatilize.
Causes harm to the respiratory system
In addition, glass is a high-energy-consuming industry, and a large number of harmful gases will be released during the production process, causing pollution to the global environment.
Therefore, the harm of glass is not because of the impact on human health after discarding, but its production requires more resources, which may cause serious environmental pollution.
Third, some “secrets” about plastic bottles
1. What does the number at the bottom of the plastic bottle mean?
There is usually a triangle at the bottom of the plastic product, the number in the center indicates the number, and the bottom will indicate the plastic material in English. Different materials, different application scenarios, and different safety to use.

Marked with 1
: Polyethylene terephthalate (PET), commonly used in beverage bottles, not resistant to high temperature, short shelf life;
Marked with 2
: High-density polyethylene (HDPE), commonly used in food and drug packaging, not easy to clean, not recommended for recycling;
Marked with 3
: Polyethylene (PVC), commonly used in toys, tools, etc., not resistant to high temperature, easy to release harmful substances in case of high temperature or grease;
Marked with 4
: Low-density polyethylene (PE), commonly used in plastic wrap, plastic bags, not suitable for fatty food;
Marked with 5
: Polypropylene (PP), commonly used in fresh-keeping boxes and plastic boxes, is more resistant to high temperature, but it is easy to deform when it exceeds 200 °C;
Marked with 6
: Polystyrene (PS), commonly used in fast food boxes, transparent packaging boxes, avoid high temperature;
Marked with 7
: OTHER, commonly used in yoga mats, suitcases, etc., should not contact food.
2. Can the plastic container be heated in the microwave or filled with hot water?
The numbers mentioned earlier 1-7 indicate different materials, and also correspond to their heat resistance.
No. 5 is more heat-resistant
, can withstand high temperature of about 200 ° C, can be heated in a microwave oven, repeated heating will not be a problem.
No. 1, No. 6 and other plastics are relatively poor in heat resistance, it is best not to heat directly, do not fill too hot food, of course, can not be used repeatedly.
3. Can plastic bottles be reused?
Many families will use used plastic bottles to carry oil, salt, sauce and vinegar, etc., but this practice is not recommended.
Clear studies have shown that the same PET plastic bottle at the same temperature, plasticizer dilution can be nearly 20 times different in water and oil. In addition, the pH value of vinegar is very low, if you fill vinegar with PET,
May catalyze the metal in the plastic, which is harmful to the human body
So for the sake of safety, there is really no need to take this risk, using plastic beverage bottles to divide seasonings or store food.
Regular plastic materials will not cause harm to the human body, but the wrong use method, it is easy to catalyze the plasticizer, plasticizer types are very many, most of them are toxic, so poor heat resistance plastic products, it is best to avoid reuse.
