Overweight and unhealthy diet are considered to be major causes of diabetes. Now, a study shows that air pollution is also contributive.
Polluted air triggers diabetes – More and more boys get sick
Every day in Germany, there are nearly 1,000 new cases of diabetes. "Junk Food", overweight
and obesity, as well as less and less exercise and sports were previously considered the main causes – in addition to the increase in life expectancy. But now there is a new suspect in new cases of diabetes: air pollution.
A study now concludes that one in seven new diabetes illnesses is due to contaminated air.
is caused. "Pollution has contributed to 3.2 million new cases of diabetes worldwide in 2016, accounting for about 14 percent of new cases," write authors of the study now published in the journal The Lancet Planetary Health.
"It is likely that pollution
reduces the production of insulin and causes inflammation, which prevents the conversion of glucose from blood into energy, "write the researchers from the Washington School of Medicine in St. Louis (United States)

Limits on pollutants Too high atmospheric levels
Previous studies have suggested a possible badociation between air pollution and diabetes. The new findings now come from medical data from 1.7 million American veterans studied for more than eight and a half years. None of the candidates had diabetes at the beginning of the study. Using a statistical model, the researchers examined how air pollution at their place of residence could explain why they became diabetic. Factors such as overweight and obesity have also been taken into account.
"Our research shows a significant link between air pollution and diabetes in the world," concludes Professor Ziyad Al-Aly. "This is important because many business lobbyists claim that the currently allowed limits on pollutants released into the atmosphere are too severe and should be increased," warns the scientist. Instead, there is evidence that these currently permitted levels of air pollutants are still hazardous to health and need to be lowered.
Particles significantly increase mortality
The authors of the study also badume that the proportion of diabetics suffers from polluted air. Countries where regulations are less strict – as in India
, In Papua New Guinea, Afghanistan and Guyana – are likely to be even higher.
And it's not just the risk of diabetes that preoccupies polluted air. In 2015, about 4.5 million people died prematurely from the effects of polluted outdoor air – including 237,000 children under five years old who suffered respiratory infections. This is the result of a recently published study by the Max Planck Institute of Chemistry in Mainz and the London School of Hygiene and Tropical Medicine
