Do Manufatured Chemicals, Such As BPA, Contribute to Obesity?

We do know that it is our lifestyles that are making us fat.  It is not only the amount of food we eat or the type of food we eat, but also chemicals that we ingest.  In the Key Laboratory for Endocrine and Metabolic Diseases of Ministry of Health at the Shanghai Clinical Center for Endocrine and Metabolic Diseases, Biphenol A was positively associated with generalized obesity, abdominal obesity, and insulin resistance in middle-aged and elderly Chinese adults.  Studies like this one were not only provided in China, but also in the USA.  BPA is a manufactured chemical that is found in canned food, polycarbonate-bottled liquids, and other consumer products. In adults, elevated urinary BPA concentrations are associated with obesity and incident coronary artery disease, according to the Department of Pediatrics at the New York University School of Medicine.

At the Department of Pediatrics, New York University School of Medicine, Urinary BPA concentration was significantly associated with obesity in this cross-sectional study of children and adolescents. Explanations of the association cannot rule out the possibility that obese children ingest food with higher BPA content or have greater adipose stores of BPA.

The New York University says nothing on BPA effecting adults.  But, the Department of Epidemiology, Harvard School of Public Health found that higher BPA exposure is associated with general and central obesity in the general adult population of the United States.

In addition to BPA being added to canned foods and hard clear plastic, the Mayo Clinic, states that some dental sealants and composites also may contain BPA, along with epoxy resins that are used to coat the inside of metal products, such as food cans, bottle tops and water supply lines.  The ADA, American Dental Association, however does not believe there is a basis for health concerns relative to BPA exposure from any dental material.  The FDA's, U.S. Food and Drug Administration's current assessment is that BPA is safe at the very low levels that occur in some foods.

Studies have been done at a couple of departments at the Sharma University of Health Sciences, a graduate medical institute in North India located in the city of Rohtak, Haryana, and they confirm that no BPA has been detected in blood samples, indicating that there is no detectable systemic exposure to BPA from dental sealants.
