This view is mainly based on two reasons: long-term use of hot water kettle will form scale, leading to cancer; There are also rumors that the materials used to make electric kettles contain more manganese. If you often drink the water boiled in an electric kettle, the content of heavy metals in your body will easily exceed the standard, which is harmful to your health. Is that really the case? Today, let's talk about the influence of hot water kettle on human body and the problems that should be paid attention to when using hot water kettle.
1, material of hot water kettle
With people paying more and more attention to health care, many people find that the main structure of electric kettle is stainless steel or manganese steel, so they think that drinking electric kettle for a long time will do harm to health. But in fact, manganese is an essential trace element for human body. Moderate intake of manganese is harmless to the body, and only excessive intake of manganese will be harmful to the body.
Before, our country made a spot check on the quality of common electric kettles in the market, and found that the electric kettles contained manganese, but the content was not much. The boiled water in the electric kettle will not lead to excessive intake of manganese, and the manganese content in the electric kettle is not much, so it will not cause harm to the body if it is used normally.
2. Scale produced by boiling water
After long-term use, a large amount of scale will be produced in the hot water kettle. Many people think that these scales are carcinogens, so they think that drinking the water in the kettle for a long time may be toxic or even carcinogenic. Is it true?/You don't say. /You don't say. Obviously wrong. In fact, the main components of scale in hot water kettle are magnesium hydroxide and calcium carbonate. These substances are formed during the heating of tap water.
Tap water in our life usually contains calcium and magnesium ions and some carbon dioxide dissolved in water. During the heating process, water will be hydrolyzed into hydroxide ions, which will combine with magnesium ions to form magnesium hydroxide with low solubility. In addition, carbon dioxide dissolves in water to form carbonic acid, and carbonate ions formed by heating carbonic acid will combine with calcium ions to form calcium carbonate, which will also be deposited in the pot. Therefore, these substances will not have a great impact on the human body and will not cause cancer.
1, choose a regular manufacturer to buy.
When we choose to buy electric kettles, the most important thing is to buy some qualified electric kettles, namely 304 stainless steel electric kettles. Many people may say, I just want to buy a 304 stainless steel electric kettle, but I can't see the difference. Who knows which is the 304 stainless steel electric kettle? After all, high manganese steel electric kettle and 304 stainless steel electric kettle are basically the same.
In fact, it is very simple to buy a qualified electric kettle. First, from the brand point of view, the quality of big brand electric kettles is naturally guaranteed and will not be faked casually; Second, look at the trademark. The wall of qualified electric kettle is often engraved with the "304" sign. Besides, you should also remember that what you get is what you pay. It is impossible to buy a good electric kettle at a very cheap price. Therefore, in daily life, you should be careful when choosing an electric kettle.
2. Don't drink boiled water
Many people think that boiling water can cause cancer. Actually, this is just a rumor. Some people think that boiling water for thousands of times will cause cancer, because it will make water contain nitrite, and nitrite itself is a carcinogen, so they think that boiling water for thousands of times will cause cancer. But in fact, there is no need to worry about this at all. According to the survey, a person must drink at least 20 tons of boiled water at a time to have nitrite poisoning, so boiled water will not cause cancer.
Since it won't cause cancer, why not recommend drinking it? In fact, this is because drinking water is not only to supplement the water needed by the human body, but also to absorb trace elements and minerals in the water. Thousands of boiling water is repeatedly boiled, which will lead to a large loss of nutrients and minerals in the water and affect the absorption of nutrients in the water.
3, regular cleaning scale
Most drinking water in China belongs to hard water, which contains a lot of calcium and magnesium. After long-term use, the bottom of the electric kettle is easy to scale, and with the passage of time, scaling will become more and more. If these scales are accidentally drunk into the stomach, it is easy to form kidney calculi, which will affect our health. In addition, the appearance of scale will reduce the heating efficiency of the kettle and cause energy waste.
So it needs to be cleaned regularly. These scales can be dissolved by acid, so there is no need to wipe them hard when cleaning them. You can pour some white vinegar into the kettle, leave it for a while, and then treat it, and it will be easy to remove it.
In fact, the correct use of electric kettle in life has no effect on our health. As long as we pay attention to the products with quality assurance when buying the electric kettle, pay attention to whether the water source is clean and pay attention to the maintenance of the electric kettle, we can use the electric kettle safely.
