Drinking water is the second major event in life after eating, and the cup of drinking water is directly related to this major event in life, right? If you use the wrong cup, it is equivalent to drinking poison!
What cup do you use for drinking water every day? Today we will reveal the secrets of various cups!
stainless steel cup
In daily use, it is not a big problem to use stainless steel cups to hold ordinary water, but do not hold acidic drinks, such as juice, coffee, carbonated drinks, etc., because heavy metal substances are easy to breed, so it is not safe to drink ordinary water again.
When cleaning stainless steel cups, do not use strong oxidizing soda, bleaching powder, etc. These substances are also easy to chemically react with stainless steel.
- porcelain cup
The ceramic cup without colored glaze, especially the colorless inner wall, is also the first choice for drinking water. Not only the material is safe, it can withstand high temperatures, but also has a relatively good insulation effect. Drinking hot water or tea is a good choice.
Do you have beautiful colors and cute patterns on your drinking glass? If so, change it as soon as possible. The colorful patterns on the ceramic cup are actually a kind of paint, which may hide safety hazards.
Especially the inner wall is coated with glaze. When the cup is filled with boiling water or a beverage with high acidity and alkalinity, the lead and other toxic heavy metal elements in these pigments are easily dissolved in the liquid. People who drink liquids with chemical substances will cause harm to the human body.
It is best to use uncolored glaze!
Health index：★★★★☆ / ★☆☆☆☆
The glass does not contain organic chemicals during the firing process. When people drink water or other beverages from the glass, they don't have to worry about the chemicals being drunk into their stomachs. Moreover, the glass surface is smooth, easy to clean, bacteria and dirt are not easy to breed on the wall of the cup, so it is the healthiest and safest for people to drink water from a glass.
Drinking water is the safest!
- plastic cup
And the internal microstructure of plastic has many pores, which can easily hide dirt. If it is not cleaned, bacteria will grow easily. Therefore, when purchasing a plastic cup, you must choose a cup made of food-grade plastic that meets national standards.
Toxic substances are easily precipitated when hot water is installed!
Not all plastic cups are suitable as water cups. Be sure to check whether there is a QS logo when purchasing. At the same time, there is a small triangle symbol on the bottom of the cup, which is their ID card.
- Enamel cup
Although the metal substance contained in the enamel cup is relatively stable, it may dissolve in an acidic environment. Therefore, it is best not to use an enamel cup to hold acidic drinks such as orange juice for a long time, otherwise ordinary water will contain metal substances.
In addition, the surface of the enamel cup is easy to be damaged after being bumped, and harmful substances will be precipitated.
It is safer, but do not hold acidic drinks for a long time!
- Disposablepaper cup
Some paper cup manufacturers add a lot of fluorescent whitening agent to make the cup look whiter. It is this fluorescent substance that can cause cell mutations, and once it enters the human body, it will become a potential carcinogen. And from the perspective of environmental protection, disposable paper cups should be used as little as possible.
There are many health risks and it is not environmentally friendly!
1. The safest is: glass cups, ceramic cups without colored glaze.
2. The most unsafe: disposable paper cups, plastic cups, colorful ceramic cups.
3. Note: Do not use stainless steel water cups, enamel water cups, and drink coffee, orange juice and other acidic beverages.
