★ Plastic cup: Plastic belongs to chemical polymer materials, and most of them are harmful to human health. Boiling water and hot water are packed in plastic cups, and toxic chemicals in plastic are easily released into water. In addition, the plastic surface looks smooth. In fact, there are many pores in the microstructure, and dirt is easily hidden in the pores, so half of the plastic cups can't be cleaned or even sticky, and the bad plastic cups have an odor.
★ Ceramic cup: The inner wall of a ceramic cup is usually coated with a layer of glaze. When the glazed cup is filled with boiled water or high acid-base drinks, heavy metals such as lead in the glazed glass are easy to precipitate, which is harmful to human health. Therefore, it is best to choose natural color cups for ceramic cups instead of colored glass cups with colorful inner walls.
★ Magnetized cup: There are many medical reports at home and abroad. The magnetized water obtained through the magnetized cup has certain effects on human health and the treatment of some diseases. However, not all magnetized water is beneficial to human health, and some may even be harmful. Magnets are divided into positive and negative poles. The water treated by the positive magnet should not be drunk excessively, and the negative magnetized water can improve human health and enhance human physiological efficacy. Therefore, the magnetized cup needs to choose a unipolar magnet (drinking water negative pole).
★ Energy Cup: The energy cup refers to a cup made of far infrared materials (mostly non-metallic crystal minerals and rare elements). The energy released by far-infrared materials can break the hydrogen bonds between water cluster clusters and make water in the state of small molecular clusters. This kind of small molecular water is easily absorbed by human cells and can participate in all life metabolism activities in cells more effectively, thus enhancing human metabolism, immunity and adaptability, and improving human physiological functions.
Five "Most Healthy" Water Cups
The healthiest glass
The reason why the glass is the healthiest is that it has two health characteristics: first, the glass contains no chemicals during the firing process, so when people drink water or other drinks from the glass, they don't have to worry about the chemicals being drunk into their stomachs; Second, the glass surface is smooth and easy to clean, and bacteria and dirt are not easy to breed on the cup wall.
When buying glasses, you'd better choose transparent glasses and carefully choose colored ones. It doesn't matter whether there is a pattern on the outer wall, as long as it is not on the inner wall of the glass. Glass is not the higher the price, the better, and the price is moderate. Sticking the trademarks of regular manufacturers and the inspection marks of relevant state departments is the first choice. When cleaning, use washing liquid first, and if possible, it is best to put it in a sterilizer for disinfection. To judge whether the cup is washed or not, you can see the degree to which the water drops hang on the wall. A really clean cup will not hang water drops and leave no water marks.
Special note: in the cold season of winter and spring, if glass is commonly used, it can be "washed early and washed late" or "washed early the next morning". In hot summer, the cup will be covered with bacteria in three hours, so it should be cleaned every three hours.
The most common-plastic cups
Plastic cups occupy a dominant position in the water cup market because of their low price and convenient carrying. In recent two years, super sealing has become a major feature of plastic cups. However, plastics often contain some toxic chemicals, which will dissolve in water when encountering hot water or boiling water, thus endangering human health. Therefore, it is best not to use plastic cups to fill boiling water or hot water, but to clean them thoroughly and disinfect them with a sterilizer.
The warmest thermos cup
The inner container material of the thermos cup is the same as that of the daily thermos bottle. We all know that the insulation effect of household thermos is quite good, and so is the insulation cup. In the cold winter, when you go out for a meeting or play, you are afraid that there is no hot water to drink on the road. It's really a good choice to put some hot water in the thermos. For patients with diabetes and some chronic diseases, it is necessary to drink hot water at any time, and the thermos cup is also the first choice. However, it is necessary to remind everyone not to use a thermos cup to make tea, because many nutrients in tea will be greatly reduced at high temperature and constant temperature, thus affecting absorption.
Special note: Generally, thermos cups bought in large shopping malls have a shelf life. After you buy it, you can check whether the insulation performance of the thermos cup is good by the following methods. The cup is filled with hot water. After two minutes, the lower part of the non-insulated cup will become hot, while the lower part of the insulated cup will always be cold.
The most controversial-magnetized cup and energy cup
At present, the most controversial cups on the market may be magnetized cups and energy cups. Theoretically, these two kinds of cups meet the hygiene requirements, but there is no testing experiment to prove whether the materials can achieve the theoretical effect. Moreover, these cups are expensive, and many people think that high prices are definitely good products based on high-quality standards. Actually, it's not. In other daily necessities, it is indeed a penny for a penny, but there is no such thing as developing new products. If you really want to buy a functional cup, you'd better choose one that has been tested by the national quality monitoring department.
The most suitable tea-purple sand cup
The purple sand cup is made of purple sand, which is a natural special mineral soil. There are three colors of purple mud, red mud and green mud, which are collectively called purple mud. After processing and firing, they are made into healthy purple sand cups or teapots with unique Chinese charm. Why is the purple sand cup best for making tea? First, purple sand has a double-hole structure, which has good hot and cold rapidity, so you don't have to worry about the cup bursting whether it is hot or cold. In addition, the purple sand cup is easy to absorb tea juice, and the inner wall is not brushed without odor. The accumulated tea rust, which contains griseofulvin in biological tests, has anti-inflammatory and detoxification effects. And the longer the purple sand cup is used, the brighter and more attractive it will be.
Special note: whether you make tea in a glass or a purple sand cup, it is best to drink it within 2 hours. After more than 2 hours, the amine substances in tea will react with other substances to produce substances harmful to the body. So, don't make tea repeatedly. Soaking for a long time is equivalent to overnight tea.
