In the family group, Dian Ge can be shocked 10 times a day!
"Fluoride toothpaste, carcinogenic!"
"Drinking coffee causes cancer!"
"Put the phone on the pillow side, carcinogenic!"
These rumors have taken advantage of everyone's fears to create more anxiety.
However, "talking about toxicity aside from the dose is a hooligan."
What scientists have not studied has actually been done by rumor-mongers.
Rest assured, fluoride toothpaste can effectively prevent caries.
Brother Dian reminds:
Children need to use fluoride toothpaste under the supervision of their parents.
Coffee is really wronged to death!
Not only does coffee not cause cancer, but it may also reduce the risk of skin, oral, and throat cancers, liver and endometrial cancers [2].
Healthy adults consuming 400 mg of caffeine per day is not much of a problem [3].
Drinking poisoning or even death, you need to drink 75 to 100 standard cups of coffee at a time, and you may not have waited for that step, you have already been full.
From the old mother's obsession: "Don't put the mobile phone on the side of the pillow, carcinogenic!" ”
Mobile radiation lying gun!
In 2011, the International Agency for Research on Cancer under the World Health Organization classified electromagnetic radiation into the category "probable carcinogenic" meaning "possibly carcinogenic": it is currently impossible to prove carcinogenic, but it is worth paying attention to!
Due to the lack of scientifically rigorous expression, mobile phone radiation carcinogenesis has become a rumor, and there is no evidence of a relationship with health problems, including cancer[4].
But Brother Dian still feels that don't put the mobile phone on the pillow, if you are not careful, the night will pass!
When brother Dian saw this, the cups in his hand fell off.
Say it out loud: no carcinogenic!
But to distinguish the use of the cup, keep your eyes open and carefully look at the ingredient list of the cup:
Polyethylene: As long as it is within the shelf life, cold water and hot water are leveraged ~
Edible paraffin coating: often used at low temperatures.
You can't drink it with this kind of paper cup! hot! drink!
By the way: plastic lunch boxes will not cause cancer, use it!
Say it out loud: No!

As long as the non-stick pan is purchased in a formal place, there is no need to worry about carcinogenic problems when looking for national standards.
Usually the temperature of stir-frying is up to about 200 degrees Celsius, to reach 500 degrees Celsius [5], the coating of the pot will be burned out, unless there is a red child at home, spraying real fire every day or rest assured to use it~
However, it is important to note that:
Non-stick pan for a long time to cook acidic food (such as meat, eggs, sugar, rice) or the coating is broken, peeling off, there will be heavy metals and other harmful substances sneak out [6], then you need to change the pot ~ ~
Nitrite, on the list of carcinogens in category 2A, however, focuses on the following:
1.2 The meaning of A
Possibly carcinogenic, evidence of carcinogenicity in humans is limited, and evidence from laboratory animals is sufficient.
2. Dosage
The lowest toxic dose of oral nitrite in adults is approximately 0.3 to 0.5 g, and 1 to 3 g is fatal [7].
Translation: To eat the lowest dose of poisoning, you need to eat about 6 pounds of overnight vegetables! Are you sure you can eat so much at once?
3. How it is stored is important: put it in the refrigerator!
Experiments have shown that after 24 hours of overnight vegetable storage at 4 degrees Celsius, the carcinogen nitrite content is similar to that of the first pot.
At room temperature, about 25 degrees Celsius leafy vegetables such as stir-fried cabbage, hollow cabbage, lettuce, Chinese cabbage, oil wheat vegetables...
Their nitrite content has increased significantly, even exceeding the limit value set by the state, so it is best to eat it within 6 hours! (The sooner the better, try not to stay)
Say eight hundred times: no carcinogenic!
Experiments have shown that tap water is boiled eight times and the nitrite content is 3.38 μg/L [9].
The national food safety standard stipulates that the nitrite content in drinking water should not exceed 5 μg/L [10].
Drinking water can be drunk a few times, so let's put our hearts in our big stomachs!
Long press the picture below and forward it!
Like, retweet, collect, let these rumors nowhere to hide!
