Glass cups, enamel cups, ceramic cups, plastic cups, iron cups, aluminum cups, paper cups, stainless steel vacuum insulated cups... When we go to shopping malls to buy water cups, all kinds of cups will break into our sight. Experts remind that the first choice for drinking glasses should be glasses.

Of all the cups made of materials, the glass is the healthiest. Professor Li Fuxing, director of the Health Water Professional Committee of the Chinese Medical Promotion Association, has counted the characteristics of glass cups. The glass does not contain organic chemicals during the firing process. When people drink water or other beverages with glass cups, they do not have to worry about chemical substances. It is drunk in the belly, and 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 with a glass.

In addition, experts also advocate the use of enamel cups, because enamel cups are made after enamelling at a high temperature of thousands of degrees, and they do not contain harmful substances such as lead, so they can be used with confidence. However, experts have raised doubts about cups made of other materials. The colorful ceramic cups are very flattering, but in fact, there are huge hidden dangers in the bright pigments, especially the inner wall is coated with glaze. When the cup is filled with boiling water or drinks with high acidity and alkalinity, these pigments The lead and other toxic heavy metal elements in the liquid are easily dissolved in the liquid, and people drink liquids with chemical substances, which will cause damage to the human body. Plasticizers are often added to plastics, which contain some toxic chemicals. When using plastic cups to fill hot or boiling water, the toxic chemicals are easily diluted into the water, and the internal microstructure of the plastic has many pores. Hidden dirt, it is easy to breed bacteria if it is not cleaned. Some medical reports claim that magnetized water is beneficial to human health, but in fact, not all magnetized water is beneficial to human health. Only the magnetized water of the negative electrode can improve the physiological functions of the human body and play a role in health care, and the water treated by the positive electrode should not be consumed too much. Most of the magnetized cups we see on the market use ordinary magnets, regardless of the positive and negative poles.
