A few days ago, Aunt Zhao and Aunt Li exchanged health knowledge. Aunt Li said that you can't drink the water boiled by the electric kettle for a long time at home, otherwise it may be poisoned and there may be a risk of cancer.
To this end, after Aunt Zhao came home, she stopped her wife from drinking water with an electric kettle. To this end, the two argued endlessly in this regard.
Aunt Zhao told her wife that after the kettle is boiled, there will be a layer of scale after long-term use, which is likely to be harmful to the body.
But Aunt Zhao's uncle insisted that he was still in good health after drinking the water from the electric kettle for so many years. So what exactly is the scale in the electric kettle? How is it formed?
First, the origin of electric kettle scale
The electric kettle has been boiled for a long time, and scale will appear in many cases because there are various compounds in the water. If you cook them in an electric kettle, they may stick to the wall of the kettle.
There are many compounds attached to the kettle wall, which will turn into scale over time, but it should be noted that these scales will basically not bring hidden dangers to people's health.
Now everyone knows that scale will not affect human health, so some people will say that electric kettle boils water, and there may be heavy metals in the water exceeding the standard. Is it true?/You don't say.
Second, do the heavy metals in the water burned by the electric kettle really exceed the standard?
Many people have heard that drinking water from electric kettles can cause cancer and poisoning, which is really scary, because most people basically drink water from electric kettles. Some people will say that the manganese content of electric kettle is particularly high. If you ingest this content in your body for a long time, it will increase your risk of cancer.
Manganese is also found in trace elements in our bodies. If the body is seriously deficient in manganese, then the body will be particularly unhealthy. Therefore, moderate intake of manganese will make the body healthier, but if the intake of manganese is particularly high, that is to say, excessive intake of manganese will definitely have great hidden dangers to the health of the body.
Is it true that the manganese content in the water boiled by electric kettle exceeds the standard? Now ordinary electric kettles are all made of 304 stainless steel, and the electric kettles made of this material have no manganese. Even in the electric kettle made of high manganese steel, the existing structure of manganese is very small, and it is difficult to excite manganese by boiling water every day.
Therefore, it is impossible to boil water with excessive manganese in the electric kettle, and everyone can use it with confidence. So which is more suitable, 304 stainless steel electric kettle or high manganese steel electric kettle?
According to the research professor, more than 90% of the ingredients used in the manufacturing process of these two electric kettles are the same, but there is a gap in one ingredient. Add nickel to 304 stainless steel kettle and manganese to high manganese steel kettle.
The functions of these two elements are basically the same, except that the cost of the kettle made of 304 stainless steel is relatively high, but the glossiness and corrosiveness are better than that of the electric kettle made of high manganese steel.
So now we know that when you buy an electric kettle, you can choose according to your own needs.
Third, is the water repeatedly burned by the electric kettle really poisonous?
After reading the above contents, we know that drinking water with electric kettle is very healthy and there will be no health hazards, but some people say that if water is boiled repeatedly with electric kettle, such water will be toxic. Is it true?/You don't say.
It is said that boiling water repeatedly with an electric kettle will cause a particularly high nitrite content. Drinking this water for a long time will be particularly unhealthy and lead to poisoning.
According to this statement, a food testing center tested this repeatedly boiled water, and the nitrite content in the repeatedly boiled water did increase, but the nitrite standard in the water met the edible nitrite content. Even if the water is boiled and left for a day or two, the nitrite content in the water is hundreds of times different from the nitrite consumption standard in China.
It can be seen that drinking water repeatedly boiled by electric kettle will not be poisoned, which is all people chatting after meals, and there is no scientific basis at all.
Fourth, how to use the electric kettle correctly?
There are also many precautions when using an electric kettle. You must use the electric kettle correctly, so as to be safer and healthier.
1, when boiling water, do not exceed the rated water level of the electric kettle. If you put more water when boiling water, a lot of water will overflow after boiling water, which is prone to leakage.
Also note that when boiling water, you should not put too little water. It is most suitable to put it at normal water level. Some electric kettles have a circuit above the kettle wall when boiling water. If there is too little water at this time, the upper part of the kettle will be in a dry state, which will have a great impact on the service life of the kettle.
2. Some electric kettles have been used for a long time, and the power-off function will become particularly poor. When the water boils, if there is no automatic power off, it will keep boiling. When the water dries up, it may cause a fire. Therefore, when boiling water with an electric kettle, pay more attention to the state of boiling water.
3. The general electric kettle may have scale in it after several months of use. At this time, the scale must be cleaned in time, and the electric kettle must be cleaned before use, which is safe and secure.
We should also drink more water in our daily life, which will benefit our metabolism and our health.
