Drinking water boiled by an electric kettle for a long time is harmful to the body and causes cancer? 3 suggestions to listen to
Do you use an electric kettle to boil water at home?
There are actually many people who use electric kettles to boil water and drink, especially those who work and rent outside, and use electric kettles more frequently.
Recently, there have been rumors that the water boiled by the electric kettle will have excessive heavy metals, and may also cause cancer and poisoning, causing many people to dare not use the electric kettle. Is this statement true?
1. Will the water boiled by the electric kettle exceed the standard of heavy metals and cause cancer?
The argument that the water boiled by the electric kettle will exceed the standard of heavy metals is mainly due to the concern that the high-manganese electric kettle will precipitate the heavy metal manganese element , causing poisoning. But in fact, China's stainless steel industry once issued a report, pointing out that high manganese stainless steel will not release a large amount of heavy metals such as manganese, nor will it cause heavy metal poisoning.
Moreover, the human body also needs some manganese . The "Reference Intake of Dietary Nutrients for Chinese Residents" recommends that adults should consume 3.5 mg of manganese per day, and even 10 mg of manganese per day will not harm their health.
The National Food Safety Risk Assessment Center has tested stainless steel products and found that the amount of manganese migration in stainless steel products is far below the upper limit of human absorption. Therefore , it is wrong to say that stainless steel kettles cause cancer .
2. The electric kettle is scaled, can I still drink it?
During the use of the kettle, a layer of white scale will gradually form, and the scale is actually a kind of precipitation of bicarbonate. When the water containing calcium ions and magnesium ions is heated, white precipitates such as calcium carbonate and magnesium carbonate are produced, which then adhere to the wall of the pot, and then scale is formed.
There is scale to prove that the water quality is hard, even if the scale is drunk in the stomach, it will not harm the health of the body.
After the scale enters the human body, part of it will be decomposed and excreted under the action of gastric acid, and part of it will be absorbed by the human body. There is no need to worry about kidney stones, etc. However, it should be noted that the scale will lead to poor thermal conductivity of the electric kettle and waste of electricity.
3. It is very important to use the electric kettle safely
When using the electric kettle every day, you must pay attention to safety. It is best not to be too full of water, not to overflow the minimum or maximum scale, and to ensure that the base is dry when using it. When using, try to add water first and then turn on the electricity to avoid potential safety hazards, and choose products that can be used independently for sockets and power cords, so as to prolong the service life of the electric kettle.
If you find that there is scale under the electric kettle, you need to remove it regularly. You can choose to wipe with baking soda or soak in lemon juice to remove the scale inside the kettle .
Summary: The statement on the market that the electric kettle boils water will cause heavy metals exceeding the standard and poisoning, etc., is actually not correct. Usually, you need to choose a regular brand of electric kettle products. During the use of the electric kettle, scale may occur. Although it will not harm human health, it may cause the thermal conductivity of the kettle to deteriorate. It is recommended to pay attention to the safe use of the electric kettle. Regular To remove scale, you can choose to wipe with baking soda or soak in lemon juice to clean the scale.
