Fight against smog, not just masks~~~

The news that "Israel research found for the first time that the average life expectancy in northern China was 5.
5 years lower than that in the south due to smog" is on fire! The results of this research were jointly signed by Professor Yuyu Chen from Peking University, Professor Hongbin Li from Tsinghua University, Professor Ebenstein from the Hebrew University of Jerusalem, and Professor Greenstone from the Massachusetts Institute of Technology in the Proceedings of the National Academy of Sciences on May 28, 2013.

Who is that?Haze weather is a state of atmospheric pollution.
Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.
5 (particulate matter with an aerodynamic diameter less than or equal to 2.
5 microns) is considered to cause haze weather.
The "culprit"
.
How powerful is it?Respiratory systemlocal bronchial ventilation function declines, bronchiole and alveolar ventilation function is lost, resulting in a decline in the resistance of the respiratory system to infection, causing respiratory diseases such as bronchitis, emphysema, and bronchial asthma
.
The cardiovascular system　　interferes with the function of the central nervous system; directly enters the circulatory system to induce thrombosis; stimulates the inflammation of the respiratory tract and releases cytokines, causing vascular damage, leading to thrombosis
.
　　Carcinogenicity: The particles contain a variety of carcinogens and carcinogens
.
　　Eating helps food! 　　Studies have shown that after entering the alveoli, fine particles such as PM2.
5 are difficult to be cleared by the human body.
It will increase the human body's oxidative stress level and inflammatory response level
.
　　Therefore, in our daily diet, we should eat more foods that are beneficial to reduce inflammation and improve the body's antioxidant capacity, adjust our own living and eating habits, improve the ability of human tissue repair, and stay away from various risks of lung cancer and cardiovascular and cerebrovascular diseases.
Factors
.
　　Foods rich in antioxidants　　vegetables and fruits contain a variety of polyphenols and carotenoids, which have antioxidant effects
.
Try to choose fresh, dark fruits and vegetables.
The darker the fruits and vegetables, the stronger their antioxidant properties.
For example, blueberries, strawberries, mulberries and other purple-red fruits rich in anthocyanins have better antioxidant effects than peaches, pears, and purple cabbage.
Oxidation is better than cabbage
.
　　Foods rich in n-3 series polyunsaturated fatty acids　　n-3 series polyunsaturated fatty acids mainly come from vegetable oil (containing linolenic acid) and fish oil (mainly containing EPA and DHA)
.
They have certain biological activity in the prevention and treatment of coronary heart disease, hypertension, arthritis, other inflammatory and autoimmune diseases and tumors.
Among them, EPA also has the effect of preventing cardiovascular diseases
.
In smoggy weather, you can eat more fish and aquatic products, reduce the intake of red meat that increases inflammation, and eat less smoked barbecue meat containing carcinogens
.
　　Carrots rich in vegetarian food　　carotene has anti-oxidant, anti-tumor, and immune function
.
Carrots, pumpkins, mangos, papaya and other fruits and vegetables, fruits and vegetables rich in carotene, are beneficial to the prevention of lung cancer and other cancers, as well as to the prevention of cardiovascular and cerebrovascular diseases
.
The smog significantly increases the risk of lung cancer and cardiovascular and cerebrovascular diseases.
Therefore, these foods are also indirectly fighting the smog! 　　Studies 　　on foods rich in vitamins have shown that nutrients such as vitamin B6, vitamin B12, folic acid, vitamin C and vitamin E can reduce the damage to health caused by air pollution.
For example, vitamin B6 can promote the synthesis of antibodies in the body.
When lacking, the synthesis of antibodies is reduced and the body resists.
The force drops
.
Increasing vitamin C and vitamin E intake will reduce asthma symptoms and so on
.
　　Therefore, eat more foods rich in vitamins, chicken and fish are rich in vitamin B6, animal foods are rich in vitamin B12, animal offal and green leafy vegetables are rich in folic acid, fresh vegetables and fruits are rich in vitamin C, vegetable oils, nuts, beans rich in vitamin
E .
　　There are many ways to fight the smog! 　　Now that you know that there is no way to remove it after inhalation, you must reduce the amount of inhalation as much as possible
.
　　In haze weather, minimize outdoor activities
.
If you must go out, wear a protective mask that can filter out most of the PM2.
5 particles in the air
.
　　Do not wear contact lenses
.
In haze weather, because of low air pressure, corneal hypoxia is aggravated, and particulate pollutants can irritate the eyes and cause eye allergies or infections
.
　　Drink plenty of water, keep your respiratory tract moist, and try to breathe through your nose
.
　　After returning home, wash your face, rinse your mouth and clean your nasal cavity
