Uncle Liu is 63 years old this year. He is usually in good health. Since he retired, he began to learn some health knowledge. After learning that drinking tea has many benefits, he often has something to do and nothing to drink.

One day, my son came to visit Uncle Liu. Seeing that Uncle Liu poured the boiling water from the electric kettle into the teacup, his son was even more anxious and said the first sentence of the article. Uncle Liu listened to his son's advice and didn't listen at all. He said, I have been drinking water boiled in an electric kettle for more than ten years, and I am in good health. Uncle Liu's son saw that his father was so stubborn and said nothing more.

In recent years, electric kettle has been loved by everyone because of its convenience and low price. However, online comments on electric kettles are endless. Some people think that drinking water from electric kettles for a long time will not only cause poisoning, but also cause cancer. Others believe that electric kettles will be tested before leaving the factory, and qualified electric kettles can be listed. So which view is correct? In order to let everyone know more about the electric kettle, today, the doctor will talk to you about the relevant knowledge.

Before answering this question, let's find out where this view comes from.

Some people think that drinking boiled water from electric kettles for a long time will cause poisoning and increase the risk of cancer, mainly because tap water contains chlorine and manganese in electric kettles exceeds the standard. Both chlorine and manganese are harmful to human body. This view sounds reasonable, but it can't stand scrutiny.

The tap water we usually use is not directly taken from reservoirs or rivers, but the product of filtration and disinfection in waterworks, which mainly uses chlorine for disinfection. Although chlorine is poisonous, no matter the dose, talking about poisoning is hooliganism. The water in the waterworks will be tested before entering the user's home. Only when the chlorine content in tap water reaches 0.3 4mg/L can tap water be qualified. Otherwise, the chlorine in tap water is too low to be disinfected, and the chlorine in tap water is too high to cause poisoning.

As for the manganese in the electric kettle, it is still possible. As we all know, there are many brands of electric kettles on the market. In order to reduce the production cost, some small factories may use high manganese steel to make kettles. Long-term use of this electric kettle to boil water will easily lead to excessive manganese in the body, thus increasing the risk of cancer. However, it should be noted that the electric kettles produced by regular manufacturers meet the requirements and their safety is guaranteed. In fact, most electric kettles on the market still have no problem.

Therefore, drinking tap water from electric kettles for a long time does have the possibility of poisoning and cancer. But as long as the kettle we buy is produced by a regular manufacturer, drinking tap water from the electric kettle for a long time will not be toxic and carcinogenic.

? Buy electric kettle, try to choose big brands:

We try to choose big brands when buying electric kettles. Although the price of electric kettles of big brands may be a little more expensive, other materials and safety are guaranteed. It takes many years for big brands to accumulate fame. They know that fame is hard to come by, so they will cherish it even more.

Never buy some inferior electric kettles to save money. If you use inferior kettles for a long time, the toxic substances in them will be gradually released, which will definitely endanger your health in the long run.

I have been in contact with a patient before. Because of the poor conditions at home, he bought an inferior electric kettle. Results After more than two years, he suddenly developed symptoms such as nausea, vomiting, abdominal pain and sore throat. After going to the hospital, I did a lot of tests and was finally diagnosed with manganese poisoning.

? Regularly clean the scale in the electric kettle;

After the electric kettle is used for a period of time, the inner wall of the kettle is easy to produce some scale.

If the scale in the electric kettle is not cleaned in time, it will not only waste electricity, but also reduce the service life of the electric kettle. As we all know, the thermal conductivity of scale is not good, and its thermal conductivity is1100110 of steel. If you want to boil water, you need to consume more electricity. Poor thermal conductivity of scale will cause heat to accumulate locally, which will reduce the service life of electric kettle in the long run. # Health Star Project #

In addition, if the scale is not cleaned up in time, it may also cause heavy metal poisoning. Some people have studied the scale before and found that all the heavy metals contained in it exceeded the standard. This is mainly because some scale will dissolve in water after heating. The part of scale dissolved in the scale may bring heavy metals into the water. At the same time, some heavy metals may be attached when the scale is peptized. Therefore, it is necessary to clean the scale in the electric kettle regularly.

Maybe many friends are not good at cleaning scale. Let me introduce it. White vinegar is mainly used to clean scale. We add white vinegar to the kettle, dilute it with clear water, and then heat it. Stop heating when the water boils, and then soak for half an hour. # Health 2022#

? Try to choose an electric kettle with 304 stainless steel liner;

When we choose the electric kettle, we need to pay attention to the brand of the electric kettle and the material of the inner container. Try to choose the material of the inner container as 304 stainless steel.

304 stainless steel belongs to food grade stainless steel, with low heavy metal content and high stability. Even if the electric kettle made of this material is used for a long time, less harmful substances will be precipitated.

Therefore, when purchasing an electric kettle, try to look at the inner container of the electric kettle as much as possible, and try to choose an electric kettle made of 304 stainless steel. # Health Science Competition #
