Cancer-causing drinking glasses, you must drink from glass, see the following report. Tuesday, March 12, 2019, today is Arbor Day. We usually use such as glasses, paper cups, stainless steel cups and ceramic drinking cups in the end will not cause harm to the human body? Water is the source of all life, human life has long been inseparable from water, and how to choose the cup of drinking water is safe, is the health and health issue that we must pay attention to.
Recent warnings about the cancer risk of plastic cups have been repeated:
In 2007, Canada's health department banned the import and sale of polycarbonate plastic beverage bottles.
In 2009, a number of states in the United States legislated to ban polycarbonate manufacturing baby bottles, beverage bottles, food containers... Because it contains the carcinogen bisphenol A.
The ABC website also recently issued A warning that bisphenol A, a substance that can increase the risk of cancer, was found in the inside of plastic baby bottles, plastic jugs and canned food packaging.
In this regard, American medical experts suggest that consumers should try to drink water with glasses or ceramic cups without colored glaze on the inner wall; Plastic cups should only be used to drink room temperature water.
According to the survey, 4 kinds of cups are dangerous to drink from:
1, metal cup drinking coffee will dissolve:
Metal cups, such as stainless steel, are more expensive than ceramic cups. The metal elements contained in the composition of the ceramic cup are usually relatively stable, but in an acidic environment, it may dissolve out, and it is not safe to drink acidic drinks such as coffee and orange juice.
2, disposable paper cups or hidden potential carcinogens:
Disposable paper cup is made of paper cup paper, and the paper in the production process must undergo the process of wood becoming fiber, and the color is relatively miscellaneous and not white enough. To this end, some manufacturers in order to bleach paper, artificially add fluorescent whitening agents. Expert introduction, fluorescent whitening agent is a kind of fluorescent dye, can stimulate the incident light to produce fluorescence, so that the dyed material to obtain similar fluorite sparkling effect, the naked eye looks very white, is widely used in the paper industry. However, the paper cup paper is different from the general paper, which belongs to the food wrapping paper, and it is prohibited to add fluorescent whitening agents. Because fluorescent whitening agents are toxic organic compounds, entering the human body may cause cell mutations and become potential carcinogenic factors.
3, plastic cups are the easiest to hide dirt:
Plastic cups should also be out of favor. Because plasticizers are often added to plastics, which contain some toxic chemicals, when plastic cups are filled with hot water or boiling water, toxic chemicals are easy to dilute into the water, and the internal microstructure of the plastic has a lot of pores, which hide dirt, cleaning is not clean will easily breed bacteria. Therefore, when purchasing plastic cups, be sure to choose a cup made of edible grade plastic that meets national standards.
4. Multicolored water cups are prone to heavy metal poisoning:
Colorful cups are attractive, but for your health and safety, it is best not to use them. Because there are huge hidden dangers in those bright pigments, especially the inner wall is coated with glaze, when the cup is filled with boiling water or acid and alkaline drinks, the toxic heavy metal elements such as lead in these pigments are easily dissolved in the liquid, and people drink the liquid with chemical substances, which will cause harm to the human body.
[Expert Advice] :
In daily life, the repeated use of beverage bottles and mineral water bottles is very common. Many consumers often like to keep their used beverage bottles and mineral water bottles, and fill them with tea or drinking water when they go out next time, calling this "environmental protection" and "saving". Experts said that qualified beverage bottles and mineral water bottles are required to be made of food-grade plastic, that is, PET bottles. These food-grade PET bottles do not withstand high temperatures and need to be used at low temperatures, generally safe to use below 70 degrees Celsius. In addition, these plastic bottles are disposable, and the state stipulates that enterprises can not be recycled and reused.
[Safest drinking cup] :
1. Glass:
Of all the materials, the glass is the healthiest. The glass does not contain organic chemicals in the process of firing, when people drink water or other drinks with the glass, do not have to worry about the chemicals will be drunk into the stomach, and the glass surface is smooth, easy to clean, bacteria and dirt is not easy to breed in the cup wall, so people drink water with the glass is the healthiest and safest.
However, 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 accidentally burn themselves, if the water temperature is too high, it may also cause the cup to burst, and it is necessary to avoid holding hot water.
2. Ceramic cup without colored glaze:
Drinking water is preferred without colored glaze coated ceramic cup, especially the inner wall should be colorless. Not only the material is safe, high temperature resistance, but also relatively good thermal insulation effect, drinking hot water or tea is a good choice.
After understanding this knowledge, we have to choose safe and sanitary cups when drinking water, and the glass is a good choice.
