Generally, drinking water is used to replenish water loss in the body. The human body needs a lot of water every day. People who go to work often drink water from plastic cups. Experts suggest that from a health point of view, except porcelain cups, other cups are unhealthy.

1, disposable paper cups or hidden potential carcinogens

Disposable paper cups just look hygienic and convenient, but in fact, the product qualification rate can't be judged, and whether it is clean or not can't be recognized by the naked eye. From the perspective of environmental protection, disposable paper cups should be used as little as possible. In order to make the cup look whiter, some paper cup manufacturers add a lot of fluorescent whitening agents, and it is this fluorescent substance that will mutate cells once it enters the human body and become a potential carcinogen; Secondly, those unqualified paper cups are generally soft and easy to deform when poured into water. Some paper cups are poorly sealed, and the bottom of the cup is easy to seep, which makes it easy for hot water to burn your hands. What's more, if you gently touch the inside of the paper cup with your hand, you can feel fine powder on it, and it will turn white when you touch it with your fingers. This is a typical inferior paper cup.

2, the metal cup will dissolve when drinking coffee.

Metal cups, such as stainless steel, are more expensive than ceramic cups. Metal elements contained in enamel cups are usually stable, but they may be dissolved in acidic environment, which is unsafe for drinking acidic beverages such as coffee and orange juice.

3, plastic cups are the easiest to shelter evil people from evil.

Plastic cups should also be a relatively unpopular one, which contains some toxic chemicals, because plasticizers are often added to plastics. When hot water or boiled water is filled in plastic cups, toxic chemicals are easily diluted into water. There are many pores in the internal microstructure of plastic, which contain dirt. If it is not cleaned properly, bacteria can easily breed. Therefore, when purchasing plastic cups, you must choose food-grade plastic cups that meet the national standards.

Safest water cup:

1, glass

Among all the cups made of materials, glass is the healthiest glass, and it contains no organic chemicals in the firing process. When people drink water or other drinks from glasses, they don't have to worry about chemicals being drunk into their stomachs. Moreover, the glass is smooth and easy to clean, and bacteria and dirt are not easy to breed on the glass wall, so it is the healthiest and safest for people to drink water from the glass.

However, although glass contains no chemicals and is easy to clean, users can easily burn themselves because of the strong thermal conductivity of glass materials. If the water temperature is too high, the glass may burst, so it is necessary to prevent hot water from being filled.

2. Colorless glazed painted ceramic cups

Not only is the material safe, especially the inner wall should be colorless, but the ceramic cup coated with colorless glaze is the first choice for drinking water, which is resistant to high temperature and has relatively good heat preservation effect. Drinking hot water or tea is a good choice.

Eighty percent of adults don't know how to wash cups, so cleaning the bottom of cups is very important.

Everyone uses cups every day, but do you clean them every day? What is the focus of cleaning and what kind of detergent is the best? These seemingly simple questions are closely related to health.

If it's too much trouble, it's best to wash the cup immediately after each use, at least once a day, and then dry it before going to bed at night. When cleaning the cup, not only the cup mouth, the cup bottom and the cup wall can not be ignored, especially the cup bottom, if not cleaned frequently, a large number of bacteria and impurities may precipitate. Experts especially remind female friends that lipstick not only contains chemical components, but also easily absorbs harmful substances and pathogens in the air. Drinking water will bring harmful substances into the body, so the lipstick left at the mouth of the cup must be cleaned. It is not enough to wash the cup with water. You might as well brush it with a brush. In addition, because the important component of detergent is chemical synthetic agent, it should be used carefully and washed with clear water. If you want to clean cups with more oil stains or tea stains, you can squeeze toothpaste on the brush and brush it back and forth. Because toothpaste contains both detergent and very fine friction agent, it is easy to wipe off the residual substances without damaging the cup.
