Eating, drinking water, etc. are the prerequisite for maintaining good health. Experts say that drinking plenty of water can promote metabolism, which is conducive to physical health. But there are also saying that overnight water and thousands of rolling water will cause cancer and not drink. Is this true or not?
1. Is it carcinogenic?
The dad’s assessment team had done experiments, sampled separately from barrel water and tap water, collected 34 water samples, and handed water samples to Zhejiang Province Inspection and Quarantine Science and Technology Research Institute.
After a week of time, it was found that whether it was boiling water many times or water that continued to boil for a long time, the nitrite content was under low limit, and you could drink it safely.
The test of overnight water found that the boiled water did not have a lot of bacteria breeding for one day, two days, and three days overnight, and you can rest assured.
Second, these two kinds of water, don’t drink
Compared with overnight water and thousands of rolling water, the following two kinds of water are not recommended to drink.
1. Old winter melon water
The old melon water placed at the old age will breed a lot of bacteria, and even restore nitrate to nitrite. After drinking this melonwater, it may cause nitrite poisoning, which will cause the brain, kidney, heart and other organs. Oxygen may endanger life.
2. Spicy water
The World Health Organization divides the hot water (hot drinks with water temperature exceeding 65 degrees) into 2A carcinogens, with hot water with a temperature of more than 65 degrees. It may be buried for esophageal cancer.
Third, can drinks replace water? What kind of water is best for your body?
Many people think that Bai Shui is not delicious and wants to use drinks to replace water. Can the drink instead of water? Let’s take a look at the experiment together!
CCTV reporters purchased milk tea, fruit juice, carbonated beverages, and tea beverages for experiments, and found that these beverages were made into different lollipops after being cooked. The weight of each lollipop was about 15 grams. Among them, milk tea was boiled at the least, less than one, and the rock sugar Sydney was boiled the most, and 4 were boiled.
Experts point out that drinking sugary drinks may cause obesity, dental caries and other diseases, which is not conducive to physical health, so it cannot be used to replace water with drinks.
Du Songming pointed out that the most advocated drinking is boiled boiled water. It is recommended to drink 1500-1700 ml of water every day when the temperature is appropriate.
Essence Although there may be some scale in the boiled water, Professor Liu Wenjun of the School of Environmental College of Tsinghua University pointed out that most of the water is relatively high, and high water hardness does not harm the human body, so don’t worry too much.
Summary: The overnight water and thousands of rolling water passed on the Internet cannot be drunk. It is not true after experimental, but it is relatively not recommended to drink. In comparison, the old melon water, hot water and other water may endanger the health of the human body. We must avoid drinking these water. It is generally recommended to drink boiled water, not to replace water with drinks, so as not to increase the risk of obesity and dental caries, and may increase the burden on other organs of the body.
