Indiscriminate selection of drinking cups may harm health

Drinking water is the second most important thing in life after eating. I have to take a cup of water every day. How do you pick up a water cup? Different choices of cups have different effects on health. Let’s follow Xiaobian to learn which cup is suitable for drinking water and how to clean it!

◆ check the quality of the four cups

1. Stainless steel cup

Stainless steel cups are alloy products. Improper use will release the heavy metals contained therein, which is harmful to health. In daily use, it is not a problem to pour ordinary water in a stainless steel cup, but do not put acid drinks. If juice, coffee, carbonated drinks, etc., heavy metals are easy to precipitate, so it is not safe to drink ordinary water again. When cleaning the stainless steel cup, do not use strong oxidizing soda, bleaching powder, etc. these substances are also easy to react with stainless steel.

Stainless steel cup summary: it is not a problem to hold ordinary water, but do not put acidic drinks.

2. Ceramic cup

There are two kinds of ceramic cups. The first type is a ceramic cup without colored glaze and colorless inner wall. Especially, the inner wall should be colorless, which is also the first choice for drinking water. Not only is the material safe, it can withstand high temperature, but also has a relatively good insulation effect. Drinking hot water or tea is a good choice.

The second is colorful. Do you have beautiful colors and lovely patterns on your water cup? If so, replace it quickly. The colorful patterns on the ceramic cup are actually a kind of pigment, which may hide potential safety hazards. In particular, the inner wall is coated with glaze. When the cup is filled with boiling water or drinks with high acidity and alkalinity, toxic heavy metals such as lead in these pigments are easy to dissolve in the liquid. If people drink liquid with chemical substances, it will cause harm to human body.

3. Glass

Among all kinds of glasses, 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, they don’t have to worry about the chemicals being drunk into their stomachs. Moreover, the glass surface 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 in a glass.

Glass summary: drinking water is the safest!

4. Plastic cup

Plastic cups are also unpopular. Plasticizers are often added to plastics, which contain some toxic chemicals. When plastic cups are used for boiling water, toxic chemicals are easily diluted into the water. And the internal microstructure of plastic has many pores, which is easy to hide dirt. If it is not cleaned, bacteria will easily breed. Therefore, when choosing plastic cups, you must choose drinking cups made of edible grade plastic that meet the national standards.

Summary of plastic cup: hot water is easy to release toxic substances!

◆ cups should be cleaned frequently.

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

It is best to clean the cup immediately after each use. If it is too troublesome, it should be cleaned at least once a day. It can be cleaned before going to bed at night and then dried. When cleaning a cup, you should not only clean the mouth of the cup, but also the bottom and wall of the cup. In particular, if you don’t clean the bottom often, you may deposit a lot of bacteria and dirt. Female friends are particularly reminded that lipstick not only contains chemical components, but also easily adsorbs harmful substances and pathogens in the air. Drinking water will bring harmful substances into the body, so the lipstick remaining at the mouth of the cup must be cleaned. It is not enough to wash the cup with water, and it is better to brush it with a brush. In addition, as an important component of detergent is a chemical synthetic agent, it should be used cautiously and washed clean with clean water. If you want to clean a cup with a lot of grease, dirt or tea stain, you can squeeze toothpaste on the brush and brush it back and forth in the cup. Since there are both detergent and very fine friction agent in the toothpaste, it is easy to wipe off the residual substances without damaging the cup.

◆ precautions for cleaning cups

Cleaning: cups need to be cleaned frequently. It’s better to buy one with a cup cover when shopping, so that bacteria can’t easily enter the cup. It’s better to clean the cup with detergent or hot water at high temperature.

Placement: the cup should be placed away from computers, refrigerators and other household appliances, because the effect of static electricity will make the cup absorb more bacteria and dust.

Ventilation: keep the room or office environment ventilated. Ventilation can let dirty air and dust drift away, which can reduce bacteria and dust entering the cup.
