Nowadays, electric kettles have become household appliances in most households. Because of their small size, convenience and low price, they are very popular among the public. However, there are rumors on the Internet that , Drinking water boiled by an electric kettle for a long time will not only lead to human poisoning but also may cause cancer. Is this true?
In fact, the material used in electric kettles is mainly high-manganese steel. There are comments on the Internet that high-manganese steel will produce manganese-containing oxides during the heating process. Although manganese is an essential trace element for the human body, However, the human body’s demand is very small. The dietary intake of manganese is about 6.8 mg, which can basically meet the body’s needs.
Excessive intake of manganese for a long time will affect the function of the nervous system, resulting in symptoms such as memory loss, lethargy, lethargy, and neurological disorders, so the harm of excessive intake is very great. But in fact, using a high-manganese steel kettle to boil water will not generate manganese-containing oxides during the heating process, and the precipitated manganese element is very small, which will basically not cause damage to the human body.
In addition, according to the experiment conducted by the Center for Disease Control and Prevention in Laoshan District, Qingdao, electric kettles in residents’ homes were randomly selected, and new electric kettles in supermarkets were also tested. For the first electric kettle, the water samples were placed for 12 hours before, after and after boiling, and the contents of seven metals such as nickel and iron did not change significantly.
So, most of the electric kettles on the market are actually safe, and there is no risk of poisoning or cancer. As long as the water is heated, it is still safe to drink.
