Pollution could be a risk factor for diabetes
Helmholtz scientists Zentrum München , in Germany, together with researchers from the German Center for Research on Diabetes (DZD), found that air pollution increases the risk of insulin resistance and a pre-diabetic type 2. The results were reported in the journal Diabetes. > To reach the results, data were analyzed of approximately 3,000 people participating in the study, who live in the city of Augsburg and two adjacent rural counties. Each participant was interviewed and evaluated physically.
The researchers also collected blood samples from fasting participants, which indicated several markers of insulin resistance and inflammation. The hormone leptin has also been examined, as has adipokine (protein), which has been linked to insulin resistance. Non-diabetics underwent an oral glucose tolerance test to identify whether the metabolism of the substance was impaired.
The data were compared to the pollutant concentrations in the atmosphere of the place of residence of the participants using predictive models based on measurements repeated at 20 sites (for particle measurements) and at 40 sites (for nitrogen dioxide measurements) in the analyzed regions. "The results showed that people who already have impaired glucose metabolism, so-called pre- diabetics are particularly vulnerable to the effects of air pollution, "said Kathrin Wolf, lead author of the study." In these individuals, the association between increases in blood markers and increased concentrations of air pollutants is particularly Thus, in the long term - especially for people with impaired glucose metabolism - of the air is a risk factor for type 2 diabetes.

Breast milk is the only food that can meet all the nutritional needs of the baby up to six months of life, and should be supplemented with healthy food after this period until two years of life or more. It is able to feed, strengthen the bond between mother and child and immunize the child against different diseases.
Research shows that the function metabolic syndrome is critical for women to prevent cardiovascular disease and type 2 diabetes after they reach menopause. Thinking about it, researchers at the University of Missouri in the United States found that a small amount of exercise can contribute to postmenopausal women's health by regulating insulin, maintaining metabolic function and helping to prevent significant weight gain .
