Whose house collapsed?
I quickly watched:
According to Reuters, people familiar with the matter said the International Agency for Research on Cancer, a subsidiary of the World Health Organization, plans to announce on July 14 that aspartame is listed as "possibly carcinogenic to humans."
Look at it again:
Aspartame is a common artificial sweetener used to replace sucrose.
Aspartame is found in Coca-Cola, Pepsi, Sprite and Fanta.

It was myself who collapsed.
Scared.
Quickly drink a sip of Coke to suppress the shock.
So, this is about Buzz Lightyear.
But let's see.
According to World Health Organization standards, drinking water is also carcinogenic -
Of course, it has to be water above 65 degrees!
Aspartame may be classified as a Class 2B carcinogen, and the same grade carcinogen is coffee.
And carcinogens more terrible than "aspartame" are working night shifts, being tony, eating red meat, eating fried chicken, drinking heavy wine...
If you're a night shift Tony who drinks coffee in the morning, fried chicken at noon, and alcohol at night, my advice is to drink the bushi.
I know!
Regardless of dosage, talking about toxicity is hooliganism.
So where is the boundary of this measurement?
Today let's talk about sugar and sugar-free.
Absolutely shock your cognition all the way.
sugar
In 2014, a documentary called A Movie About Sugar was born.
The main thrust of the content is two words: to die.
Truly die.
A young man named Damon has been eating sugar-free foods for several years.
But this time, he will experiment with his own body.
The experiment was set to eat 40 spoons of sugar a day, insist on eating for 60 days, and observe the changes in the body.
The 40 spoons must come from foods that are generally considered healthy, not junk food.
Such as chocolate, carbonated drinks, candy...
40 spoons of sugar, at first glance, is a lot, but this is the amount of sugar per capita in Australia.
1 tablespoon of sugar is about 4 grams, and 40 tablespoons of sugar total 160 grams.
The experiment will be accompanied by four advisors:
A writer, a dietitian, a blood specialist, a doctor who tests indicators.
In this way, he ensures that his physical data is presented in time and professionally analyzed and explained.
Before the experiment, Damon's daily calorie intake was 2300 calories, which came from fat, protein, and carbs.
When experimenting, Damon after increasing the proportion of sugar in the diet.
It is still necessary to keep the total calorie intake unchanged and keep exercising every day.
On the first morning, Damon ate two small bowls of oatmeal yogurt and drank a glass of juice.
He was surprised to find that the sugar content in these three foods could reach 20 spoons.
So easy？
That is, without eating any junk food, Damon can easily ingest 40 spoons of sugar.
Especially juice.
If one apple gives you 4 spoons of sugar, eat two bodies and feel full.
But squeezed into juice, you can probably drink four apples in one go, which is equivalent to eating 16 spoons of sugar.
And the drinks on the market have a more terrifying sugar content.
No wonder it's called the "sugar wave".
After 12 days, Damon gained 3.2kg.
After 14 days, Damon began adding pure sucrose to his diet.
Eat cookies, plus!
Eat chicken drumsticks, plus!
At one point, he even took 7 spoonfuls of pure sugar in a cookie and swallowed it.
You kid is really fighting.
The last time I saw this burning sensation in the mouth was in "Jennifer's Flesh".
What's the difference between this and burning it with a lighter.
"Jennifer's Flesh"
Note that in order to keep the total calorie intake constant, he also deliberately chose to eat low-fat foods when choosing food.
Eighteen days later, when Damon had a blood test, he found fatty liver.
When sugar enters the body, it is divided into two parts: fructose and glucose.
Once in the liver, glucose is converted into energy or stored as energy.
With fructose, when energy stores are full, fructose turns into fat.
And it accumulates more and more.
After a few more days, Damon woke up feeling physically exhausted.
But after taking a sip of the drink, I immediately felt the excitement of my brain.
The light in the young man's eyes was gone
His wife said he was always absent-minded and lost his concentration.
He himself can clearly perceive the rise in mood when eating sugar, and about 1 hour later ushered in a low tide.
Does this mean that if you are in a bad mood and eat something sweet, you may just drink to quench your thirst.
After 35 days, it was getting harder and harder for Damon to keep exercising.
His skin began to acne, fat accumulated on his stomach, and his face became puffy.
After 45 days, Damon discovered the magic of his body: he was beginning to accept the way he now ate, and his brain was regulating the ups and downs of emotions.
Although he was already emaciated.
The 60th day has arrived.
When Damon was tested, the most obvious change was in the liver.
The alanine aminotransferase index jumped from a healthy value below 20 to the safety line.
When the liver is damaged, alanine aminotransferase is released into the bloodstream.
Triglyceride levels, the amount of fat in the blood, rose from a healthy 0.08 to a dangerous value of 1.5.
He gained 8.5 kg and his waist soared by 10 cm.
Merchants have been subtly cultivating a point of view:
Fat because of gluttony and laziness.
Gluttony consumes more calories, while laziness consumes very few calories.
The calorie difference between the two leads to obesity, not eating sweets leads to obesity.
Eat sweets and you can exercise more.
"Hunger Platform"
But as far as Damon himself is concerned, he eats avocados, nuts, etc., absorbing even more calories than sugar.
But it caused a worse physical condition.
Does this mean that where to absorb heat is also important?
Of course, because there is only one experimenter, it is not possible to draw an absolute conclusion.
Sugar-free
Why does sugar make people happy?
A documentary called "Institute for the Life of Young Polytechnic Workers" studied this topic in the first issue.
By the way, this documentary, which has a long name, was made by domestic science and engineering youth.
They will study a topic in each issue, and the Douban score is 9.0.
Let's get back to business.
There are sweet taste receptors on the taste buds, and when sugar binds to the sweet taste receptors, electrical signals stimulate our brain's reward pathway.
Releases a neurotransmitter called dopamine.
Dopamine makes us happy.
Sex is the same as nicotine.
However, happiness will become more and more difficult.
In 2019, a professor at Aarhus University injected 7 piglets with sucrose solution for 12 consecutive days.
An MRI image of the piglet's brain was recorded after the injection.
Image display:
The thalamus, amygdala, striatum, nucleus accumbens, etc. have all experienced varying degrees of usability decline.
Freshness decreases and less dopamine is released.
More sweetness is needed each time to stimulate.
The thirst for sugar, infinitely increased, is bound to cause hidden health concerns.
Back in 2009, a professor gave a famous lecture "Sugar: The Bitter Truth".
The dangers of sugar are finally being realized by the public.
However, as time progressed, "sugar substitutes" appeared.
What is a "sugar substitute"?
As the name suggests, substances that replace sugar (white sugar, granulated sugar, sucrose, glucose).
Sugar substitutes generally have two advantages:
First, only need to add a little, you can achieve the same strength of sweetness as sugar;
According to China's General Principles for Nutrition Labeling of Prepackaged Foods:
As long as the sugar content in liquid food is less than 5g/L, it can be labeled sugar-free on the package.
To use an analogy:
A 330ml of sugary Coca-Cola contains about 33 grams of sugar (fructose and sucrose), and the same aspartame required for the sugar content of a can of sugar-free Coca-Cola is only 167.5 micrograms.
Therefore, many food packages have a "sugar-free" logo because of the addition of trace sugar substitutes.
It's not nothing.
Second, its heat is extremely low, or even no heat.
Take erythritol and erythritol, for example.
Erythritose can participate in chemical reactions in the human body, is catalyzed by enzymes in glycolysis, becomes phosphorylated fructose, and then continues to be converted to be absorbed by the body.
The sugar substitute erythritol, there is no enzyme to catalyze it, it is not absorbed after entering the human body, and it is excreted and then out.
Therefore, many food packages have the "zero sugar" logo, followed by the "zero card" logo.
But then another problem arises.
That is, many people think that the taste of "sugar-free" is not as good as that of "sugar".
Just look at a picture and understand -
Time intensity graph of sweetness.
The vertical coordinate is the sweetness intensity and the abscissa is the time.
When the sweetness intensity is equal, they produce sweetness at different speeds and durations.
Again, take diet Coca-Cola as an example.
It is fortified with acesulfame potassium, aspartame, sucralose, as a source of sugar flavor.
But aspartame and sucralose sweetness lasts much longer than sucrose, causing the sweetness to stay in the mouth for too long.
Moreover, other studies have shown that acesulfame K can bind to human bitter taste receptors.
This may be the reason why some people feel that drinking sugar-free cola is bitter and like drinking Chinese medicine.
Diet Cola adjusted the recipe several times.
It is in the pursuit that after combining several sweeteners, its sweetness intensity, occurrence speed and duration, infinitely close to sucrose.
Although, diet drinks taste different from sugary drinks.
But sugar-free beverages are becoming increasingly attractive to consumers.
The data shows:
Between 2014 and 2019, the compound annual growth rate of sugar-free beverages in China exceeded 40%. Among them, the compound annual growth rate of sugar-free sparkling water is close to 50%, and the total amount also accounts for half of the tens of billions of market.
And when buying drinks in the supermarket, I also consciously look for so-called sugar-free products.
But, can "sugar substitutes" be eaten indefinitely?
As early as May this year, the World Health Organization issued a Guide to the Use of Non-Sugar Sweeteners.
The Guide states:
Non-sugar sweeteners are advised against weight control or to reduce the risk of noncommunicable diseases.
The study of "sugar" and "sugar-free" is still ongoing, not finished.
We can neither demonize nor be vigilant.
Finally, to borrow the words of Chen Junshi, academician of the Chinese Academy of Engineering and expert in nutrition and food safety:
"Everything is under the big hat of a balanced meal, to be balanced."
