Food contaminants worsen metabolic problems in obese mice

Obesity is a major public health problem because it is a risk factor in the development of metabolic complications (diabetes, cardiovascular diseases, etc.). It is a multi-factorial disorder. In addition to genetic predispositions and a life style that combines overeating with lack of exercise, there is a great volume of proof to suggest that contaminants, particularly in the food we eat, are responsible for the obesity epidemic and the resulting metabolic changes.
Researchers have put forward the hypothesis that contaminants in food could worsen certain metabolic problems already caused by eating an over-rich or a high-fat diet.
The tendency to become obesity has obviously increased for most people over the last 30 years. I have never believed that this is simply a matter of eating more and exercising less. While certainly multifactorial, chemical exposures look like one suspicious part of the equation. Another reason to try to clean up our food choices and our environment in general. However, the task is a tough one since we don't know exactly what to avoid or where it might be hiding.
