What cup of drinking water is the healthiest?

The knowledge of drinking water has been said a lot. Many people have already learned which waters should be drunk, which should drink less or not, but the selection of cups is rarely considered. Cups and water are inseparable. The cup was chosen wrong, still unhealthy.

Drinking water for a lifetime, test you: drink the preferred cup?

Glass, enamel cup, ceramic cup, plastic cup, stainless steel cup, iron cup, aluminum cup, paper cup... When we go to the mall to buy water cups, all kinds of cups will break into our sights, especially The brightly colored and uniquely shaped cups are even more eye-catching, and they are picky when picked and picked.

Tell you, the glass should be preferred when drinking water.

Don't think that the glass is just transparent. In all the cups, the glass is the healthiest. The glass contains no organic chemicals. When people drink glass or other beverages, they don't have to worry about chemicals being drunk into the stomach. The glass surface is smooth and easy to clean, so people drink glass with water. Healthy and safe.

Second, experts also advocate the use of enamel cups.

Because the enamel cup is made after a high temperature of thousands of degrees Celsius, it does not contain harmful substances such as lead, so you can use it with confidence.

Plastic cups can be seen everywhere. The most colorful cups are very flattering. In fact, there are huge hidden dangers in those bright pigments. When the cups are filled with boiling water or acidic or alkaline beverages, these pigments The toxic heavy metal elements such as lead are easily dissolved in the liquid, and people who drink a liquid with a chemical substance may cause harm to the human body.

Plastics are often added with plasticizers, which contain some toxic chemicals. When using hot water or boiling water in plastic cups, toxic chemicals are easily diluted into water, and the internal microstructure of plastics has many gaps, which are hidden. Dirt. Therefore, experts reminded that when purchasing plastic cups, it is necessary to choose a cup made of food grade plastics that meets national standards.

What is the magnetized cup and the energy cup?

In addition, there is a relatively large team in the water cup family, which is the “magnetized cup” and “energy cup” promoted by the merchants.

Medical reports at home and abroad do claim that magnetized water is beneficial to human health, but not all magnetized water is beneficial to human health. Only the magnetized water of the negative electrode can improve the physiological function of the human body and play a role of health care, and the magnetized water of the positive electrode should not be drunk.

Most of the magnetized cups we see on the market use ordinary magnets, and the positive and negative poles are not divided. Therefore, consumers should carefully identify when selecting a magnetized cup, and purchase a magnetized cup made of raw material (negative electrode).

In principle, the "energy cup" can also improve the function of the human body and play a role in health care. However, many manufacturers of "energy cups" on the market today have not verified the physiological effects of this function, exaggerating the role of the "energy cup", and some even claim to be able to cure all diseases. Experts remind consumers that when purchasing an "energy cup" with health benefits, they should recognize the legal certification given by the relevant departments and must not blindly follow.

Extension: Eight adults are not good to wash the cup. Cleaning the bottom of the cup is very important. Everyone needs to use it every day, but can you clean it every day? Where is the focus of cleaning, and what is the best cleaning agent? These seemingly simple questions are closely related to health.

According to the survey, among the 3,849 respondents, only 9.6% of the cups were washed after drinking, 40.2% washed the cups once a day, 29.7% washed the cups once a day, and 20.5% washed the cups. Lower. The focus of different people cleaning cups is different. 68% of the people focused on cleaning the cup along the mouth, 24.1% focused on cleaning the inner wall of the cup, and 5.6% mainly cleaned the bottom of the cup, and 2.3% focused on cleaning the outer wall of the cup. Respondents also had different ways to clean the cup. Simple washing with water accounted for 52.8%, 23.0% for fine washing, and 24.2% with detergent or other cleaning.

In this regard, Professor Cai Chun, director of the Department of Preventive and Health Care at Xijing Hospital of the Fourth Military Medical University, suggested that if the cup is used up, it can be cleaned immediately. If it feels too much trouble, it should be cleaned at least once a day, and it can be washed before going to sleep at night. Then dry. When cleaning the cup, not only the cup mouth should be cleaned, but also the bottom of the cup and the wall of the cup should not be neglected, especially the bottom of the cup, which is usually not cleaned frequently and may precipitate a lot of bacteria and dirt. Professor Cai Chun specially reminded female friends that lipstick not only contains chemical components, but also easily absorbs harmful substances and pathogens in the air. When drinking water, harmful substances are brought into the body, so the lipstick remaining in the cup must be cleaned. It is not enough to simply rinse with water when cleaning the cup. It is best to use a brush. In addition, since the important component of detergent is a chemical synthetic agent, the use should be cautious, and it should be washed with water. To clean a cup with a lot of greasy, dirty or tea stains, squeeze the toothpaste on the brush and rub it back and forth in the cup. Since the toothpaste contains both a detergent and a very fine abrasive, it is easy to wipe off the residual material without damaging the cup.

In response to the question “Why not wash the cup often”, up to 75.5% of the respondents felt that the cup did not need to be cleaned when it looked dirty; 15.6% felt that the cup was too deep, and the accumulated tea stain, coffee stain, etc. Not clean; 8.9% thought it was a waste of time to clean the cup, so it was too lazy to wash. Associate Professor Sun Xin of the Xijing Hospital of the Fourth Military Medical University pointed out that there may be a large number of invisible bacteria in the cup, especially after drinking sugary drinks, the speed of bacterial reproduction is very amazing. For example, an E. coli can multiply 2 million after 8 hours under optimal conditions. Therefore, if the cleaning is not timely, although the cup may not look dirty, it will contain a large amount of bacteria. For the incomplete harm of cup cleaning, 67.2% of people know that it will cause bacteria to breed, 10.5% know that tea scale will endanger health, 17% are not clear, and 2.4% only think it will affect mood, 2.6 % of people even think that there is no harm.

The cup is not clean, and the chance of developing a bowel infection is greatly increased. Therefore, the cup should be washed frequently, and the important level of "sickness from the mouth" should be put forward.
