Of all the cups, the glass is the healthiest. The glass does not contain organic chemicals during the firing process. When people drink water or other beverages from the glass, they do not have to worry about the chemicals being drunk into their stomachs, and the glass surface is smooth and easy to clean. Dirt is not easy to breed on the wall of the glass, so it is the healthiest and safest for people to drink water from a glass.
However, although the glass does not contain chemical substances and is easy to clean, because the glass material has strong thermal conductivity, it is easy for users to accidentally burn themselves. If the water temperature is too high, the glass may burst, so try to avoid containing hot water.
Carcinogenic cups:
1. Disposable paper cups or hidden potential carcinogens
Disposable paper cups only look hygienic and convenient. In fact, the product qualification rate cannot be judged, and whether it is clean and hygienic cannot be identified with 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 lot of fluorescent whitening agents to make the cups look whiter. It is this fluorescent substance that can mutate cells and become a potential carcinogen once it enters the human body.
2. The metal cup will dissolve when drinking coffee
Metal cups, such as stainless steel, are more expensive than ceramic cups. The metal elements contained in the composition of enamel cups are usually relatively stable, but in acidic environments, they may be dissolved, and it is not safe to drink acidic beverages such as coffee and orange juice.
