This kind of electric kettle has safety hazards when boiling water, beware of drinking your way into health problems

We usually drink hot water for speed and convenience, and many people buy electric kettles. My home is the same. Three months ago I saw a relatively affordable electric kettle online and bought it. It boils water quite fast, so I quite liked it. But just these past few days, a friend who sells electric kettles came to my home to hang out, saw my electric kettle, and said, try not to use this kind of "kettle" of yours, throw it away as soon as possible, so as to avoid side effects on your body. So I was very curious and asked him why?
My friend said that although kettles are something everyone commonly uses, the quality of many kettles is not good, and in order to achieve high-efficiency production, sometimes quality cannot keep up, and the electric kettle used in your home is made of high-manganese steel. This kind of electric kettle made of this material will produce the chemical element "manganese" when boiling water at high temperature. The most important thing is that if you drink water boiled in this kind of kettle for a long time, it may also affect your health, because if the manganese in our body exceeds the normal standard, it will directly affect our brain and nervous system, making us feel sleepy and listless, and in severe cases it may also And this small electric kettle manufacturing industry has many problems. A news report some time ago talked about this point: long-term use of electric kettles can lead to memory decline and other problems.
In fact, the stainless steel kettles we commonly use are high-manganese steel kettles, only the material composition inside them differs. I asked my friend very puzzledly, then what kind of kettle is good to buy?
My friend continued, actually as long as it is an electric kettle made of high-manganese steel that complies with our country's production standards, it is fine, because this kind of kettle is very unlikely to release manganese when boiling water, so when buying a kettle, just choose a relatively good-quality electric kettle, especially a kettle with the "304 stainless steel" mark, because a kettle of this material is the safest, and at the same time the price is also relatively higher.
My friend said, so try not to use this kind of unlicensed "kettle" of yours, throw it away as soon as possible. After hearing my friend finish speaking, I finally had a realization, so that was how it was, and I was so scared that I hurriedly threw away the kettle I had bought before. So I also warn everyone that when buying a kettle, you still need to look at the kettle's material and production standards.
