In a study in Durham, N.C., lab rats who were exposed to polluted air from Beijing were more likely to have cardio-respiratory and metabolic dysfunctions.
After three to eight weeks of exposure to highly polluted air, the rats gained weight. The study put pregnant rats and their offsprings into two sperate chambers, one with polluted air and the other with filtered air.
With the same diets, but different air, the pregnants rats and their offsprings’ risk of obesity and diabetes significantly increased.
The rats exposed to polluted air had higher cholesterol and higher risks for type 2 diabetes. According to researchers, this research is in line with many other studies showing how air pollution is a factor contributing to metabolic diseases.
