“A ubiquitous chemical in common plastic may play a role in the obesity epidemic. The chemical industry is unamused.”

There appears to be evidence that the damage done by bisphenol A during embryonic development may be scrambling the signals that fat cells normally receive during prenatal and neonatal development. After the initial distortion, the affected fat cells never work properly again. Affected animals are unable to properly metabolize their normal diets, leading to obesity. And guess what? The introduction of bisphenol A into the human environment in significant quantities tracks pretty closely, in timing, to the advent of the so-called obesity epidemic in the United States.
