Vehicle pollution could be a factor in obesity.

Vehicle pollution could be a factor in obesity. This conclusion comes from a French study showing that exposure to products of incomplete combustion, similar to that detected a hundred meters of a highway, an adult can be fat 2 pounds in 15 days ?? .

..Pollution, a trap to grow ...
Polycyclic aromatic hydrocarbons, such as benzo (a) pyrene and dioxin, are pollutants resulting from incomplete combustion, produced especially by car pollution and industries. In 1983, a link between body mass index and the presence of these pollutants has been suggested. Since 1999, the team of Luc Mejean (Inserm U 308, Nancy) conducts research on the effect of pollutants on fat cells and thus the weight.

Thus his team found that pollutants were able to enter, with the fatty acids (lipids) in adipocytes (or fat cells). In contrast, it appears that the pollutants prevent output of lipids in adipocytes. After injection of pollutants in mice, this is indeed what we observe. This phenomenon is accompanied by a significant increase in weight gain without food modification. This effect is reversible since mice regained their initial weight fifteen days after the cessation of exposure to pollutants. By extrapolation to humans, this weight gain corresponds to about 2 pounds for people exposed to levels of pollutants hundred times lower, but equivalent to that detects a hundred meters of a highway.

Pollution can lead to a significant weight gain
In conclusion, the pollutants from incomplete combustion disrupt the ability of fat cells to mobilize lipids, which results in making substantial weight.

The research is needed to confirm these preliminary data. Meanwhile, epidemiological studies should be established, particularly in people particularly exposed to polycyclic aromatic hydrocarbons, that is to say, living next to a freeway, an incineration plant or a polluting factory ...
