Urban smog problems occur frequently. What food should we eat to fight smog?

In autumn and winter, smog strikes from time to time. In addition to wearing various masks, is there any way to fight smog? Try diet therapy. There may be some miraculous effects.

Various polyphenols and carotenoids in foods, fruits and vegetables rich in antioxidants have antioxidant effects and can reduce the degree of oxidative stress in the body. If you seldom eat vegetables and fruits before, try to eat one catty of vegetables and half a catty of fruits every day.

Preliminary studies on foods rich in vitamins show that nutrients such as vitamin B6, vitamin B 12, folic acid, vitamin C and vitamin E can weaken the health damage caused by air pollution. For example, asthmatic children with air pollution will have a slight decrease in ventilation after increasing the intake of VC and ve.

Foods rich in carotene and chlorophyll such as carrots, pumpkins, mangoes and papaya are rich in carotene, while dark green leafy vegetables such as spinach, amaranth, rape and kale are rich in chlorophyll and carotene.

How to effectively control smog? Smog has seriously affected people's physical and mental health and normal industrial and agricultural production, but most people do not have an accurate and comprehensive understanding of smog, and they are both worried and powerless to control smog. How is the haze weather formed? How to govern? We introduce the causes and treatment of smog weather from two aspects: the well-known smog and the smog that most people don't realize.

In the past, a large amount of water was stored on the surface of soil. Because of the large specific heat capacity of water, it can absorb a lot of heat in the air, thus reducing the temperature. Water absorbs heat into gas and rises into clouds. This process purifies the air, promotes air convection and reduces smog. Clouds turned into rain and fell to the ground, once again purifying the air and lowering the temperature. This cycle is endless. That is, scientific and reasonable.

Industrial and agricultural production such as coal burning and automobile exhaust emits a large number of fine particles; There is still wind in the horizontal direction of the atmosphere; The vertical convection in the atmosphere is weakened (inversion phenomenon). This is currently recognized as the cause of haze weather, which is intuitive and easy to understand.

The solution is to reduce the laying of cement floor, increase the area of topsoil, and let the surface absorb, store and evaporate water. If there is no surface moisture, it is useless to rely on limited fountains, grasslands and vegetation. After all, the land area is large, water evaporates quickly, heat is absorbed quickly, and clouds are also fast. ...

For example, in Tibet with less emissions, windy summer and strong convection, the smog phenomenon is relatively weak, but this is only the appearance of smog, which does not explain why the smog in heavy industrial cities where pollutants were discharged directly more than a decade ago was not serious. At present, the main way to control smog is to reduce the emission of fine particles, which will affect the normal development of the economy.
