Is it safe to drink water from a glass?

The drinking utensils chosen during the drinking process are also very particular, and when drinking water, people generally choose glass cups or stainless steel cups. If you use a stainless steel cup to drink hot water for a long time, the metal substances in it will precipitate and dissolve into the water, causing certain harm to a person's body. Many people still choose to use glass when drinking water, but is it really safe to use glass and water?

Stainless steel cup

Stainless steel cups are alloy products. Improper use will release the heavy metals they contain, which is harmful to health. In daily use, it is not a big problem to use a stainless steel cup to hold ordinary water, but do not put acidic drinks such as juice, coffee, carbonated drinks, etc., because heavy metal substances are easily precipitated, so it is unsafe even if you use it to drink ordinary water.

When cleaning stainless steel cups, never use strongly oxidizing substances such as baking soda, bleaching powder, etc., as these substances are also easy to react chemically with stainless steel.

Ceramic cup

This type of cup has been used in China for thousands of years, and everyone thinks there should be no problem with it. But in fact, it is not. In order to attract customers, businesses now make ceramic cups colorful. In fact, this is pigment and is unhealthy. Especially when it is filled with boiling water or beverages, these pigments will fall off and mix with the water and go into the stomach. It is recommended to choose colorless ceramic cups. The more beautiful they look, the more toxic they are.

glass

Drinking water from a glass is the healthiest because the production process does not contain organic compounds. People who choose glass do not have to worry about the production of harmful substances that will harm their bodies. Moreover, the surface of the glass is smooth and easy to clean, and it is not easy for dirt to remain, so it is safest to drink water from a glass.

Plastic cup

Plastic cups contain a lot of additives during plastic production. Some plastic cups also have a strong plastic smell, which smells unhealthy. Plastic cups are also difficult to clean. After using them for a long time, dirt will accumulate and it will cause harm to your body, so it is best not to choose plastic cups.

Enamel cup

Few people use this cup now, but it was very popular in the 1980s.

Enamel cups are made after being enameled at a high temperature of thousands of degrees Celsius. They do not contain harmful substances such as lead and can be used with confidence.

Although the metal substances contained in the enamel cup are relatively stable, they may dissolve in an acidic environment. Therefore, it is best not to use enamel cups to hold acidic drinks such as orange juice for a long time, otherwise ordinary water will also contain metal substances. In addition, the surface of the enamel cup is easily damaged after being bumped, and harmful substances will be precipitated, so it should be eliminated decisively.

Friends who like enamel cups are advised to use them with confidence, but do not use them to hold acidic drinks.

Disposable paper cups

Disposable paper cups only look safe and convenient. In fact, manufacturers add whitening agents during the production process to make the cups whiter. It is possible that the raw materials they use are simply not up to standard. In fact, disposable paper cups have great safety issues. Try not to choose disposable paper cups.
