Using the wrong water glass is equivalent to drinking poison? Insulation cup, glass cup, plastic cup, ceramic cup, which is safer

"Auntie has handed the tea to you, but you don't even drink it. Are you very dissatisfied with my marriage!" Xiao Zhang yelled at his father on the side of the road.

This day was originally the day when Lao Zhang and the parents of his future daughter-in-law met. They went to the wife's house. The future mother put the hot tea in a paper cup in front of Lao Zhang, but Lao Zhang didn't take a sip until he left.

This made Xiao Zhang feel very embarrassed, thinking that his father did not give him face and was not satisfied with the marriage.

"I'm too lazy to tell you, you haven't seen the news that hot tea in a paper cup will release toxic substances? How dare I drink this tea, I'm afraid it will cause cancer after drinking it!" Xiao Zhang, walk in the direction of the house by yourself.

The use of disposable paper cups in daily life is very common, but there is a saying that "paper cups filled with hot water will release microplastics, which will harm the human body when drinking." Is it true or false? What kind of cup is safer for drinking water, thermos cup, plastic cup, glass cup?

1. Hot drinks in paper cups will release "microplastics" and harm the human body?

Does it sound scary to drink hot water from a paper cup and release microplastics? Not to mention, there really is such a study...

In November 2020, a research team from the Indian Institute of Technology published in the "Journal of Hazardous Materials" research on paper cups and microplastic particles, and found that: hot drinks are placed in disposable paper cups, and the drink will be released within 15 minutes. About 25,000 micron-sized microplastic particles are released .

Researchers believe that if the average person ingests hot drinks in paper cups for a long time, the health effects may be serious.

Is drinking water from a disposable paper cup really equivalent to drinking "poison"? Before discussing this issue, let's first understand the material of some paper cups. At present, there are three types of common paper cups on the market:

The first is made of white cardboard: fast food restaurants are used to hold dry foods such as French fries and popcorn, and cannot be filled with water;

The second is a waxed paper cup: thicker than the first, it can hold water, but cannot hold food with a temperature over 40°C;

The third is the "paper-plastic cup": waterproof, oil-proof, and the most widely used paper cup.

According to the national food safety guarantee, the raw materials of paper cups are generally mainly plant fibers. As long as the paper cups are formally produced , no fluorescent bleach can be added, and they can be used with confidence.

Are the "microplastics" released from paper cups really harmful to the human body?

In this regard, Wu Yuelan, a physician at Tongren Hospital Affiliated to Shanghai Jiaotong University, said that at present, there is no clear conclusion on the risk of microplastics to human health . According to research by the World Health Organization, most microplastic particles can be directly excreted through excretion and will not be absorbed by the intestines.

It should be reminded that the profit of disposable paper cups is low, and there are many three-no products on the market. For paper cups with uneven intima, soft paper cups, and pungent odor , it is better to avoid using them.

2. Insulation cup, glass cup, plastic cup, ceramic cup, which is safer?

In daily life, the most commonly used cups are thermos cups, glass cups, plastic cups, ceramic cups, etc. Which of these cups is safer?

1. Insulation cup

Most of them are made of stainless steel, which is not only resistant to high temperature, but also has good thermal insulation properties. Whether the mug is safe to use depends on the material. Stainless steel materials are usually divided into three types, the "codes" are 201, 304 and 316 respectively.

Generally, 201 has poor corrosion resistance and may release heavy metals. It is not recommended to buy . 304 and 316 are stainless steels with higher stability and higher safety.

It should be noted that tea, carbonated beverages, juices, etc. are corrosive to stainless steel, and there may be potential safety hazards in thermos cups. Soy milk and milk are also not suitable for thermos cups, and there is a risk of deterioration if they are kept warm for a long time.

2. Glass

Glass is the safest of all materials. It is not only resistant to high temperature, but also has a smooth glass surface, which is easy to clean, and bacteria and dirt are not easy to breed on the wall of the cup.

3. Plastic cup

The bottom of the plastic cup is printed with numbers 1-7, the higher the number, the higher the quality . However, there are generally many gaps in plastic cups, which are easy to hide dirt, and it is also easier to absorb dust and bacteria.

4. Ceramic cup

Ceramic cups are made of kaolin, clay and other raw materials and then sintered. They have the characteristics of high melting point, high hardness and durability.

People who like to drink tea and coffee like to use ceramic cups to hold drinks, because ceramic cups have low water absorption, the surface is easy to clean and will not absorb odors, and there will be no glaze cracking.

3. It is very important to choose the right cup, and it is more critical to drink the "right" water

Choosing a safe cup is to be able to drink water in a healthy way, but it is important to drink water, how to drink it, how much to drink, and when to drink it.

Water is a nutrient that every cell in the body needs, and it also helps to remove waste from the body. It can be said that water is very important to maintain a healthy state.

It is important to note that water should not be drunk until you feel thirsty.

Because when a person feels thirsty, the body is actually dehydrated at or close to 2% . When the human body is dehydrated by 2%, various bodily functions will be affected, and it may cause a series of health problems in the long run, such as gastric ulcer and joint pain.

In addition, scientific and healthy drinking water should pay attention to 3 points:

1. Drink enough water

Drinking too much water should not be too much. The amount of water supplemented every day is about 1500-1700ml (7-8 cups) of water to ensure the balance of water intake and excretion. Excessive drinking of water and excessive dilution of blood can lead to water intoxication, diarrhea, edema and other conditions.

2. Develop the habit of drinking water regularly

It is very important to drink water regularly to become a habit. The best way to drink water is to drink a glass of water early, 30 minutes to 2 hours before meals and after meals, and a glass of water an hour before going to bed. Actively increase it before and after exercise or physical activity. water intake.

3. Boiled water is the healthiest

The best water is boiled water. Drinks, honey water, salt water, etc. may increase the intake of sugar and salt, which is not conducive to health.

Water in disposable paper cups does not mean that it is harmful to human health. On the contrary, not drinking water, or drinking hot water, is even more detrimental to health. Of course, if you are worried about paper cups, it is recommended to bring your own ceramic cups or glass cups for drinking.
