Nowadays, the electric kettle has become a small household appliance, and the convenience and speed make everyone rely on it very much.
However, after the opinions of "carcinogenic" and "kidney-harming" came out, many residents had strong doubts about it, so are these claims true? Can you still drink water heated by an electric kettle?
1. Is it true that the water in the overnight electric kettle is at risk of causing cancer?
First of all, the carcinogenic cause in electric kettles is related to the "high manganese steel" substance in the inner material of the kettle, which is a steel material with high manganese elements. Because its texture is very similar to stainless steel, many businesses will set it as a substitute for qualified stainless steel in order to save costs, but the problem is that it is more prone to oxidation.
Long-term use of kettle boiling water containing "high manganese steel" will indeed lead to the gradual accumulation of harmful substances in the scale, and over time there will be a risk of cancer.
However, the main component of scale is carbonate substances, which will be decomposed with metabolism and excretion when they enter the body, and will not pose a threat to health if the harmful components do not exceed the standard.
In the "Drinking Water Hygiene Standards" document, there are also strict requirements for tap water, tap water that meets the standards will not produce a health crisis, and studies have shown that drinking more water can also dilute the concentration of calcium oxalate, which also has the effect of preventing stones.
In addition, the "manganese element" in the electric kettle exists in a dense tissue form, which makes the precipitation of manganese very limited when boiling water. Even in extreme cases, such as boiling for more than 1,000 hours, the amount of manganese released from an electric kettle is extremely small.
So the impact on human health can be considered very small and almost negligible. Therefore, as long as you choose an electric kettle produced by a regular manufacturer, you don't have to worry about carcinogenicity.
Finally, Nana has a trick up her sleeve for you to get rid of limescale. This "remover" is the vinegar that is commonly prepared at home, and the acetic acid contained in it can react chemically with calcium carbonate, the main ingredient in scale, and can produce the effect of dissolving harmful substances.
Acetic acid undergoes a chemical reaction and thus is dissolved. The method is also very simple, you only need to pour it into the kettle at your leisure, dilute it with water as needed, and finally turn on the button to heat it, and wait until the vinegar is in full contact with the limescale and dissolves for a while, you can achieve the cleaning effect.
2. Teach you 3 tricks to choose a safe electric kettle
In daily life, electric kettle is one of the small household appliances we commonly use, which is not only related to the safety of our drinking water, but also directly affects our health. Therefore, it is especially important to choose a suitable electric kettle. The right choice not only ensures hygienic and safe drinking water, but also improves the quality of life and avoids potential health risks.
The first trick: choose 304 safety stainless steel material
When choosing a stainless steel kettle, it is recommended that you give priority to materials such as 304 stainless steel or 316 stainless steel that meet food-grade safety standards, so as to ensure that your drinking is safe. You can also look out for electric kettles with the words "GB 9684-2011" or clearly marked with the words "for food contact", which meet the safety standards for direct contact with food and are a reliable choice for safe drinking.
The second trick: choose the right capacity
Choose the capacity of the electric kettle according to the actual situation of the family. Generally speaking, a family of 2-3 people can choose an electric kettle with a capacity of 1.2L-1.5L, and a larger family should choose an electric kettle with a larger capacity.
The third trick: strictly control the standards
First of all, it is best to choose a well-known big brand electric kettle, because they are more strict in the factory quality inspection, the raw materials, parts, and quality of the product are stricter, and the service quality is better.
Carefully check the logo description of the kettle and the performance parameters of the product, make sure that there is information such as the company's name, address, specifications, model number, etc., and check for any misused warnings.
3. Don't drink water like this, which may bring health risks
Drinking water, a seemingly simple daily behavior, actually contains university questions. Proper drinking habits are essential for maintaining good health, but poor drinking habits can inadvertently erode our health.
The first bad habit is that many people wait until they are thirsty to drink water, but this is precisely a bad signal, because when the body sends out a thirst signal, it is actually in a state of mild dehydration, so we need to develop the habit of drinking water.
Many people don't know that drinking a lot of water in a short period of time may cause the electrolyte balance in the body to be disturbed, especially the concentration of sodium ions, which may lead to water poisoning.
The last bad habit is to replace water with a drink. Doing so can lead to excessive intake of sugar and other additives, increasing health risks such as obesity and diabetes.
In order to maintain health, it is recommended to develop the habit of drinking water regularly, in portion, and drink clean water, and try to avoid replacing water with beverages. At the same time, adjust the amount of water you drink according to your personal situation, such as the amount of activity you have in a day or your personal weight.
