Aunt liu's children have started their own families, which usually leave two. Every day she wakes up at noon and makes some water from an electric hot pot and then makes tea。
After the afternoon break, aunt liu, as usual, used the electric hotpot to make water and tea, and felt bad for her stomach。
Aunt liu's old companion walked back with uncle wang next door and saw her face look bad and covered her stomach。
Uncle wang said, "are you drinking tea with an electric hotpot?" on the internet, it is said that this hot kettle of water is carcinogenic, and the who is said to have told everyone to stop using it.”
Listen to aunt liu, she's scared, "my stomach's sick because i drink the water from this hot water kettle."
Listening to uncle wang, auntie liu is skeptical, and wonders if she'll still drink water without a hot pot
I. Long-term consumption of water from electric hotpots, harmful to the body and carcinogenic
Is it true that the rumours that most of the electric hotpots are stainless steel, including manganese elements, which may be dissected by the burning of water, and that chronic consumption of this water may cause manganese content to exceed the standard in humans and even cause nerve damage and cancer
Let's start with the lower manganese. The manganese element is one of the trace elements essential to the human body and plays an important role in the growth and development of human bones. The highest acceptable daily manganese element for adults is 10 mg, and prolonged ingestion of over-standard manganese elements can harm the human nervous system。
However, the manganese element in the electro-heat kettle is so in the form of a dense tissue that it is generally difficult to produce daily boiled water。
Prof. Jinping kuo, faculty of materials science and engineering, beijing chemical university, stated that the above-mentioned rumours were not scientific. Because, although manganese elements are present in the electric hotpot, they do not exist in the form of separate elements, the daily cooking process is difficult to detect。
Even if repeated boiling continues for more than 1,000 hours, manganese elements in ion form are rare and do not affect human health, but care is taken to purchase regular products that meet national standards。
There are many materials and types of electric hotpots that are being sold on the market, mainly stainless steel, ceramics, glass, etc., and how should they be selected for purchase
1. Stainless steel electric hotpots
When purchasing stainless steel-based electric hotpots, it is recommended that products with the words “food exposure” or “implementation of standard gb 9684-2011” be purchased to the extent possible。
2. Ceramic electric hotpots
Instead of styling with coloured ceramic hotpots, it is best to choose products with no colour or pattern in the inner wall。
3. Glass electric hotpots
When purchasing a glass hot pot, it is preferable to choose a high-barrel glass, which is more stable and relatively safer to use。
Ii. With regard to the use of electric hotpots to burn water, these health rumors need to be clarified
A lot of families have used electric hotpots, and the rumors about the hotpots and the following must be treated rationally
1. The water in the electric hotpot cannot be heated repeatedly. High nitrite
The repeated heating of water in the net-borne hot water kettle will lead to an increase in the concentration of nitrite, which is often used to the detriment of health。
However, the amount of nitrite in the open water is very small, following a test of nitrite in the burning water carried out by financial and economic journalists, which resulted in the discovery of 0. 021 mg/l after the burning of the piped water, and 0. 038 mg/l after the burning of 20 times, which is far below the drinking water nitrite standard (≤1 mg/l) in our country, so that drinking can be assured。
Two, the electric hotpots have dirt, and burning water affects health?
Is it true that there is also a claim that the bottom of a long-lived electric hotpot leaves water, which increases the risk of stones being drank for a long time
We do have magnesium and calcium ions in the tap water that we drink, which, when burned, could be attached to the bottom as water. However, they are mainly carbonate substances and generally decomposed into the human body, and some are excreted with faeces and generally do not affect human health。
The fourth hospital attached to nanchang university, gao fokang, cautions that the use of electric hot pots should be safe and that the water should not be overfilled when burning, and that if there is water outside the canteen, it should be dryed and used again. In addition, the bottom of the electro-heat kettle is to be dry and, if the kettle fails, it is to be cleared in a timely manner and not used reluctantly。
Three: the three types of water are really harmful to the body
Ensuring that there is sufficient drinking water to facilitate the circulation of blood in the body and to promote health, but the water below is not healthy, and better not
1. Raw water
In raw water that has not been treated with some measures, substances such as eggs, bacteria, chlorine, etc. May be present and, after drinking, may cause infectious diseases or acute gastrointestinal inflammation。
2. Water placed in drinking water machines for more than 7 days
Drinkers are generally difficult to completely disinfect, with bacteria growing over a long period of time, and it is recommended that regular cleaning be done and that water be placed for more than seven days, as much as possible。
Three. Hot water
Too hot water can easily burn areas such as oesophagus, stomach mucous membranes, mouths, etc. The international agency for cancer (iarc) has classified hot drinks above 65 degrees as carcinogens of category 2a, thus avoiding the constant consumption of hot water。
Care is often taken to develop healthy drinking habits, to drink less of hot and cold water, which can cause damage to cuisine mucus or even cancer, and to drink ice water that can cause abdominal pain, diarrhoea and even heart attack。
When drinking water, the water is kept as small as possible, with a high frequency, and the time for gold to drink water is taken, as is the time for drinking water before sleeping, waking up and after night。
Many people are using electric hot pots, and it is important to deal rationally with rumours that regular products are generally purchased and used in a healthy and rational manner without undue fear of harm to the human body。
Rather than fear that burning water in the electric hotpot will endanger human health, let's drink less raw water, hot water and water from the drinking machine
