cup is the most common commodity, but the more common it is, the easier it is to make people dazzled, because there are too many kinds of it. According to the instructions of the International Food Packaging Association, choosing a cup is not a trivial matter, because it will affect your health. So, what kind of cup is the healthiest to drink water? Please see what the experts suggest.
1. Don’t drink coffee with metal cups
metal cups, such as stainless steel, are more expensive than ceramic cups. The metal elements contained in the composition of enamel cups are usually stable, but in acidic environment, metal cups may dissolve metal. Therefore, it is unsafe to drink acidic drinks such as coffee and orange juice with these cups because the dissolved metal is harmful to people.
II. The disposable paper cup may contain carcinogens
. The disposable paper cup looks hygienic and convenient. In fact, the product qualification rate cannot be judged, and whether it is clean and hygienic cannot be recognized by the naked eye. From the perspective of environmental protection, disposable paper cups should be used as little as possible. Some paper cup manufacturers add a large amount of fluorescent whitening agent to make the cup look whiter. It is this fluorescent substance that can make cells mutate and become a potential carcinogen once it enters the human body; Secondly, those unqualified paper cups are generally very soft and easy to deform after pouring water. Some paper cups have poor sealing and easy water seepage at the bottom, which is easy to scald hands with hot water; What’s more, when you gently touch the inside of the paper cup with your hand, you can feel the fine powder on it, and the touch of your fingers will turn white. This is a typical inferior paper cup.
III. plastic cups are the easiest to hide dirt
plastic cups should also be an unwelcome one. Because plasticizers are often added to plastics, which contain some toxic chemicals. When hot water or boiled water is filled in plastic cups, toxic chemicals are easy to dilute into the water, and there are many pores in the internal microstructure of plastics, which hide dirt. If they are not cleaned, bacteria will easily breed. Therefore, when purchasing plastic cups, we must choose water cups made of edible grade plastics that meet national standards.
IV. beware of heavy metal poisoning with colorful cups
colorful cups are very attractive, but it’s best not to use them. Because there are great hidden dangers in those bright pigments, especially the inner wall is coated with glaze. When the cup is filled with boiled water or drinks with high acid and alkali, the toxic heavy metal elements such as lead in these pigments are easy to dissolve in the liquid. People drink liquids with chemicals, which will do harm to the human body.
v. the healthiest cup is the glass
. Among the cups of all materials, the glass is the healthiest. The glass does not contain organic chemicals in the firing process. When people drink water or other drinks with glass, they don’t have to worry that chemicals will be drunk into their stomach. Moreover, the glass surface is smooth, the glass wall is transparent, dirt is easy to find, dirt is easy to clean, and bacteria and dirt are not easy to breed on the glass wall. Therefore, people drink water with glass is the healthiest The safest.
although the glass does not contain chemicals and is easy to clean, because the glass material has strong thermal conductivity, it is easy for users to burn themselves inadvertently. If the water temperature is too high, it may also cause the cup to burst. It is necessary to try to avoid holding hot water
VI. the ceramic cup without colored glaze coating is both thermal insulation and safe
. The ceramic cup without colored glaze coating is preferred for drinking water, Especially the inner wall should be colorless. Not only the material is safe and can withstand high temperature, but also has relatively good thermal insulation effect. Drinking hot water or tea is a good choice.
