Does drinking boiled water from electric kettle for a long time have an effect on health?

Electric kettles contain manganese that is harmful to human health, but not all electric kettles can drink when boiling water. Many families will use hot water kettle to boil water, because it is simple and fast to boil water with hot water kettle, and it is really convenient to use. Perhaps everyone has heard that boiling water in an overheated kettle is harmful to health, especially drinking water boiled in a hot kettle for a long time is very harmful to health. Is that really the case? Today I'm going to tell you whether boiling water in an electric kettle is really harmful to your health.

We generally say that the water boiled in an electric kettle is harmful to health, referring to the harmful element "manganese" in the electric kettle. Manganese is a trace element. Excessive intake of manganese seriously harms human health and even causes chronic poisoning. The early manifestations of manganese poisoning patients are general fatigue, dizziness and memory loss. In severe cases, patients may have symptoms such as increased sense of heaviness in lower limbs, unstable walking, and unclear speech.

1. Do all electric kettles contain manganese harmful to human health?

In fact, whether the water boiled in an electric kettle is harmful to health depends on the material of the kettle. Not all the water boiled in the electric kettle can't be drunk. Electric kettle materials are generally divided into three types, usually most manufacturers use 304 stainless steel to heat the kettle. The price of 304 stainless steel is higher than that of 20 1 or 202 stainless steel. Therefore, in order to reduce costs, some small manufacturers often use 20 1 or 202 stainless steel to produce hot water bottles. 304 stainless steel is called "food grade stainless steel", and its manganese content is particularly low, less than 2%, which is within the safe use range.

However, the manganese content of 20 1 and 202 stainless steel is about 10%, which is completely beyond the safe use range. It can be seen that although the hot water kettle contains manganese harmful to health. However, as long as we choose a good quality kettle to boil water, it has no effect on our health. If you buy an inferior hot water kettle to boil water, long-term drinking will do harm to human body and seriously affect our health. So how can I buy a good quality hot water kettle?

2. How to choose a qualified hot water kettle?

(1) When we buy a hot water kettle, the first thing is to look at the material of the hot water kettle. Generally, the material of the hot water kettle will be marked. As long as the material of the hot water kettle is 304 stainless steel, it means that the manganese content is within the safe use range, so you can buy it with confidence. In addition, when buying hot water bottles, try to choose some big brands of hot water bottles, so that the quality of hot water bottles is more guaranteed. Moreover, the safety factor of big brands of hot water kettles is relatively high during use. Although it will be more expensive to buy, its service life will be longer. Therefore, no matter from the health or service life, it will be better to choose a big brand of hot water kettle.

(2) Look at the logo of the electric kettle when buying. The inner and outer walls of general food-grade stainless steel kettle containers are marked with the words "304" or "GB9684", so that the electric kettle can meet the national standards.

(3) When buying an electric kettle, you should also look at the magnetism of the kettle. Generally speaking, food-grade stainless steel hot water kettle is non-magnetic. Therefore, we can also use magnets to verify the quality of stainless steel. If the kettle is not magnetic, then we can buy it with confidence.
