Water can maintain body temperature, promote digestion and increase basal metabolic rate. Water constitutes human body fluids and participates in the operation of cells, interstices and major internal organs. Drinking more water can increase the secretion of sweat and sebum, making the skin more tender and shiny. A cup of boiled water every morning can also play a role in health care.

With the development of science and technology, there are more ways for modern people to drink water. As a common household appliance, electric kettle is also the best choice for most people to drink water. The use of electric kettle is very simple. Just put cold water in the kettle, turn on the boil button, and wait quietly for 15 minutes to get a pot of boiling water.

The invention of electric kettle greatly facilitated people's life, but it also induced many contradictions invisibly. Some people say that drinking water boiled by electric kettle for a long time will have an impact on your health. Is this statement correct?

Don't ignore the "composition" of the electric kettle!

Sometimes "risk detection" is carried out, that is, the stainless steel parts used in these small household appliances are analyzed. On one occasion, a municipal market supervision administration found that 55.6% samples of a batch of electric kettle used high manganese steel, and the manganese content was about 10%. Among them, only 44.4% of electric kettles with prices below 50 yuan are qualified, and the qualified rate above 50 yuan is over 80%.

Drinking water boiled by electric kettle for a long time,

May lead to excessive heavy metals?

There is a saying on the Internet that drinking the water boiled in an electric kettle will have an impact on your health, because many unscrupulous merchants make electric kettles with inferior materials in order to get high profits from electric kettles. These unlicensed electric kettles contain a lot of heavy metal elements, and the materials used are unqualified fake and shoddy products.

This material is not inferior, but a cheaper material-high manganese steel. Manganese is an essential trace element for human body, but long-term excessive intake of manganese metal will affect the function of nervous system, resulting in memory loss, lethargy, listlessness, nervous disorder and other symptoms.

The related test results also show that the higher the manganese content in the electric kettle, the higher the manganese precipitation. For example, heavy metals, especially manganese, are more easily dissolved when this high manganese steel product is used to make acidic foods such as fruit juice.

Of course, you don't have to be too afraid to see this, because the heavy metals such as chromium, nickel and manganese contained in stainless steel produced by regular manufacturers are generally relatively stable.

How to pay attention?

What are we going to do?

But pay attention to the following points, otherwise it will cause certain security risks.

First of all, when buying an electric kettle, you must choose a qualified one. There are many kinds of electric kettles on the market, so you must learn to choose them. Don't be greedy and cheap. Although it is expensive to buy, it is more economical to use.

Unqualified electric kettle manganese and other elements may have the risk of exceeding the standard, and drinking the water boiled in this kettle is harmful to health.

Secondly, the scale in the electric kettle must be cleaned frequently. After a long time, there will be thick scale inside. These white scales are mainly calcium and magnesium, which together will not affect health, but if they are not cleaned for a long time, the service life of the kettle will be affected.

Finally, when boiling water with an electric kettle, don't fill it too full. When water boils, it boils. If the water in the kettle is added too slowly, it will overflow to the chassis after charging, which will easily burn the site after a long time.

This situation not only shortens the service life of the electric kettle, but also causes certain electricity safety.

Drink healthy water at ordinary times, so that you can live longer.

In addition, there are many stainless steel products in our life, so I suggest you:

① Do not cook acidic food with stainless steel tableware at high temperature for a long time (fish, meat, rice, wine and sugar are all acidic);

② Don't use it to decoct traditional Chinese medicine (porcelain can be used instead);

③ Do not use strong alkali or strong oxidizing chemicals to clean. In addition, small kitchen appliances such as electric kettle, soymilk machine and juicer should be cleaned in time after use. If the cleaning is not clean or timely, the residue will be moldy and smelly, and there are risks such as gastroenteritis and diarrhea.

(4) After use, it is best not to scrape the inner wall repeatedly, but to wipe it with a soft rag to prevent the protective layer from being damaged due to long-term scraping, so that harmful substances can be dissolved out.
