Two studies in the past year, one in the United States, the other in Germany, found evidence that suggests high rates of tiny-particle air pollution may be linked to rising rates of diabetes.
Some doctors believe the evidence points to a rise in "the exploding pandemic, if you will, of type 2 diabetes, particularly in urbanized areas around the world," Sanjay Rajagopalan of the Ohio State University College of Medicine in Columbus, told USNews.
In the study, the mice living in an environment with clean, filtered air remained healthy. In contrast, those that experienced real world air suffered insulin resistance and were more likely to develop belly fat and other classic prediabetic symptoms. Other metabolic diseases were also found in high quantities in subjects who were treated with "city" air.
Air pollution is consistently being found to have potential negative effects on the health of both humans and animals. Long-term exposure to particles over time may increase a person's chance of developing the disease. Investing in medical-grade air purifiers may help remove these pollutants from the home.
