Brother Dian is in the family group
I can be shocked 10 times a day
"Fluoride toothpaste, carcinogenic!"
"Drinking coffee causes cancer!"
"Put the phone on the pillow side, carcinogenic!"
These rumors
Exploited everyone's fears
Creates more anxiety
However, "talking about toxicity aside from the dose is a hooligan"
Nothing scientists have studied
It was actually made up by the rumor-mongers
Feel free to use it
Fluoride toothpaste can be effective in preventing caries
Brother Dian reminds:
Children need to be supervised by their parents
Use fluoride toothpaste for children
Coffee is really wronged to death!
Not only does coffee not cause cancer
May also be lowered
Skin, mouth and throat cancers
Risk of liver and endometrial cancer[2]
Healthy adults consume 400 mg of caffeine per day[3]
Not much of a problem
Drink to poisoning or even death
You need to drink 75 to 100 standard cups of coffee at a time
Maybe before that step, it is already full
Obsession from the old mother:
"Don't put the phone on the edge of the pillow, it causes cancer!"
Mobile radiation lying gun!
2011, World Health Organization
Affiliated to the International Agency for Research on Cancer
Electromagnetic radiation is classified as "probably carcinogenic"
Meaning of "possibly carcinogenic":
It is currently impossible to prove carcinogenic, but it is worth paying attention to
Due to the lack of scientifically rigorous expression
Cell phone radiation carcinogenicity has become a rumor
It and health problems including cancer
There is no evidence of a relationship[4]
But Brother Dian still felt 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 it is necessary to distinguish between the use of the cup
Keep your eyes open and look closely at the ingredient list of the cup:
polyethylene:
As long as it is within the shelf life, the cold water and hot water are leveraged~ ~
Edible paraffin coating:
Commonly 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!

Non-stick pans as long as purchased in a formal place, look for national standards
There is no need to worry about carcinogenic problems
Usually, the temperature of stir-fry is usually around 200 degrees Celsius
To reach 500 degrees Celsius[5], the coating of the pot will be burned out
Unless there are red children in the family, they spew real fire every day
Otherwise, feel free to use it
However, it is important to note that:
Cook acidic food in a non-stick pan for a long time
(e.g. meat, eggs, sugar, rice)
Or the coating is broken or peeled off
There will be harmful substances such as heavy metals sneaking out[6]
At this time, you need to change the pot ~
Nitrite, listed on the list of carcinogens class 2A
However, the main point is the following:
Meaning of 1.2A:
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 [8], overnight vegetables are stored at 4 degrees Celsius
After 24 hours, the carcinogen nitrite content is similar to when it first comes out of the pot
Room temperature, around 25 degrees Celsius
Leafy vegetables such as stir-fried cabbage, hollow cabbage, lettuce, Chinese cabbage, oil wheat vegetables...
Their nitrite content increases substantially
Even exceeded the limit value set by the state
So it's 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 8 times with a nitrite content of 3.38 μg/L[9]
National food safety standards stipulate:
The nitrite content in drinking water should not exceed 5 μg/L[10]
Drinking water can also be drunk by burning it a few times
Let's put your heart in your belly!

Like, retweet, collect, let these rumors nowhere to hide!
