i knew beijing's bad air was killing me slowly. but is it making me fat too? - hvac air purifier

Two years since I moved to Beijing, I think I have heard enough, thank you very much, about the dangers exposed to the long-time smog sky in the Chinese capital.
There have been studies linking pollution to low birth rates, reports of a surge in lung cancer cases, and of course, shocking studies have shown a life expectancy of 5 years.
Due to the dependence on coal, northern China is five years shorter than the South. fired heating.
But last week, perhaps the most brutal blow: a new scientific article suggested that the smog in Beijing might make me fat.
It is undeniable that I have had to loosen the old buckle with a few gaps since I was sent here.
I attribute my extra fat to a variety of factors: the advantage of carbohydratestastic, oil-
Chinese cuisine;
A hazy day when I dare not jog outside;
Liquor that is often drunk
Make soup with Chinese cooked people and late people
Night Bar meetings with journalists;
General stress and lack of sleep as a foreign journalist on the phone 24/7/365.
Also, let's face it, over 40 years old.
However, I am almost not alone in packing.
My roommate recently complained that she was 10 pounds high in Beijing for two years.
Another friend said she was "15 years old ".
"Despite the serious shortage of decent cheese, ice cream and bacon, that's all.
And not just foreigners in the United States. size.
A 2014 study in The journal The Lancet found that 28% of Chinese adult men and 27% of women were overweight or obese, compared with almost none 30 years ago.
China now has more obese people than any other country outside the United States.
So the Journal of the American Association of experimental biology is about to be published, which published a study that places pregnant mice and their offspring in two rooms in Beijing, one is exposed to outdoor air, and the other is to remove most of the particulate air pollution with a filter.
The two groups eat the same diet.
The result is eyes.
Popping: At the beginning of the experiment, there was no difference in the weight of pregnant rats in each group.
But 14 days later, the rats in the polluted air gained 7%, and by 19 days the rats gained 15%.
Their lungs were 25% heavier than the control group, suggesting severe inflammation, and, similarly, their liver was 16% heavier.
Their cholesterol (
This is the kind of "bad)
They were 51% higher, their glycerin sorbate was 46% higher, and their total cholesterol was 97% higher than that of mice enjoying filtered air.
As if it wasn't bad enough, their level of insulin resistance, a precursor to type 2 diabetes, was higher than their peers who sucked in the air to clean up the particles.
Join the conversation on Facebook> These mouse babies have a similar problem: pollution after eight weeks of birth
Exposed female mice are 10% fatter than clean mice.
There are 18% men, and the air is the same. Yowza.
I got in touch with Zhang Junfeng "Jim" at Duke University, one of the leading authors of the study.
Jim, I said, is it the air in Beijing, not my shameful lack of willpower, is it the reason why I have a spare tire in China?
"Biologically, you have evidence," he said . "(
Jim, did I say I love you? )
While the main factor in weight gain is still eating too much and exercising too little, pollution is a serious behavioral and biological factor, he said.
"Think about the children [how many days]in Beijing]
He said it is recommended not to go out for exercise due to pollution.
"It helps with weight gain, and then there is evidence that you breathe in these things and your body gets messed up with fat metabolism and glucose metabolism.
This will make things slow and the energy will accumulate in the body.
"Well, I said, but how exactly does this work in my body?
"These particles enter the lungs and the lungs will be affected;
"We use this as a measure of lung inflammation," he explained . "
"Inflammation of the lungs spills;
Think of this as a chain reaction.
The lung is not isolated, it is related to the systemic circulation system.
We measure the molecules in the blood and we see the whole body inflammation from the dirty air.
"Then we study fat tissue. . . .
Fat tissue also shows higher levels of inflammation.
This can be directly converted into weight gain as more lipids are deposited into fatty tissue.
Increase insult to injury, metabolic function
Basically, how efficient are we to break down food and turn it into energy?
Also affected
"We saw this in a dirty place.
Air mice, it increases their low-density
This is not good because it increases the level of fat in the blood and also reduces insulin metabolism associated with glucose metabolism;
"You don't want too much sugar to accumulate in your body," he said . ".
"Such dirty air will lead to more fat accumulation in the body and will also reduce the metabolism of sugar, which is directly related to weight gain.
"I called Mary Wu, the lead author of The Lancet study and a former University of Washington researcher, who is now working at Watson Health at IBM to see what she thinks about fat mice.
"It's a very interesting study," she agreed, although she warned, "We have to be careful from rats to humans.
"Obesity is really complicated," she added . " She pointed out that the increase in wealth and the increasingly sedentary lifestyle are a range of factors contributing to obesity, introducing the way fast food and pollution limit outdoor activities.
However, she said it was strange that South Korea and Japan were more industrialized and modernized than China, but did not experience the outbreak of obesity as China did.
"There may be some unique places in China, but I still haven't found research that can identify some aspects of it," she said.
Whether air pollution is an "X Factor" remains to be seen.
Meanwhile, research suggests smog may make you fat, which may help convince stubborn Beijing residents so far to wear masks at home and in the office or install air purifiers, Zhang said.
"We know that air pollution is harmful to the lungs . . . . . . But some people say, 'I am tough. maybe I even smoke. why should I worry? '
But if you say that air pollution can make you fat if you keep in touch with air pollution, maybe people will react to it.
Of course, cancer is a bigger threat, but for some, appearance means a lot.
"For me, I have decided whether reducing smog can help me lose weight.
So give me a new mask and adjust the air purifier to 11.
The swimsuit season is just around the corner.
