University of London study shows that eating more oranges against PM2.5

Once the autumn is over, the air humidity is increased, providing a good breeding and living environment for the bacteria. Studies have shown that at 9 o’clock in the summer and 5 o’clock in the evening, the number of bacteria in the air is the highest, plus this is the peak time of commuting, the dust is also the most, the air environment is very poor. In addition to wearing masks, washing your mouth and nose, eating more fruits and vegetables rich in vitamin C can also help fight pollution.

According to the latest report in the journal Epidemiology, British researchers found that eating more fruits or vegetables rich in vitamin C can reduce the harm of air pollution to patients with chronic lung disease. In this new study, researchers at King’s College London, UK, surveyed more than 200 asthma patients and patients with chronic obstructive pulmonary disease (COPD). The patient is between 54 and 74 years old, and most have a history of smoking. The researchers also recorded local air pollution levels before and after hospital admission. The analysis showed that if the concentration of traffic pollution particles increased by 10 μg/m3 in the road air, the chance of admission to asthmatic patients or patients with chronic obstructive pulmonary disease increased by 35%. Moreover, patients with the lowest vitamin C content in the body were 1.2 times more likely to be hospitalized than the highest.

Canadian environmental health scientist Michael Blau said that more and more studies have shown that antioxidants can offset some of the hazards of air pollution. In the case of vitamin C, it protects the body from free radical damage, which is usually formed when pollutants enter the lungs. Therefore, people who have a poor living environment or work in places with heavy dust pollution for a long time can eat more fruits and vegetables rich in vitamin C, such as oranges, grapes, kiwis, and peppers, which help the body resist pollution.
