BPA AND OBESITY

Another factor in America’s Obesity Epidemic.

WHAT IS BPA?

BPA or Bisphenol A is a chemical produced for use mainly in the production of polycarbonate plastics and epoxy resins.

BPA is an Endocrine Disrupting Chemical (EDC), a chemical that may interfere with the body’s endocrine system producing adverse effects.

These plastics and epoxy’s affect us because they are used in some food and drink packaging such as water and infant bottles, compact discs, medical devices, coatings on metal of food cans, bottle tops, and water supply pipes.

APHA’S APPROACH TO EDC’S

The Below link is to the American Public Health Associations Approach to Exposure to EDC’s and contains a great introduction to Endocrine Disrupting Chemicals.

EDC DISRUPTING NORMAL HORMONE RESPONSE

WHAT ABOUT OBESITY According to the CDC more than one third (78.6 million)

of adults and 17% (12.7 million) children and adolescents in the United States are obese.

Obesity leads to conditions such as heart disease, stroke, type 2 diabetes, and certain cancers which are potentially all preventable causes of death.

According to the CDC, the estimated medical cost of obesity in the U.S. in 2008 was $147 Billion.

Nutrition and Physical Activity are some of the more common aspects we look at to reverse the obesity epidemic, but obesity is a multifactorial disease.

We need to consider the role endocrine disruptors such as BPA are playing in this epidemic.

A multifactorial disease needs a multifactorial prevention approach

BPA AND OBESITY A paper from Heindel and Schug discusses how

certain EDC’s that interfere with endocrine signaling can disrupt hormonally regulated metabolic processes. These chemicals may predispose people to gain weight despite efforts to limit calories and increase physical activity.

A study from Trasande, et al., revealed an association between BPA urinary concentration and obesity in children and adolescents

A study from Savastrano et al. showed detectable BPA plasma levels in the population studied and an association between BPA and Waist Circumference (WC) ( higher BPA plasma levels were associated with higher WC).

THE PROBLEM BPA is still a common component of many

products consumed by Americans. Many Americans may not even realize BPA is

considered an Endocrine Disruptor or that it can be a factor leading to obesity.

With the current obesity epidemic, there needs to be better awareness

We need more research to better establish the association between BPA and obesity

We need better regulation of BPA in products for human consumption

CURRENT ACTIONS Senate Bill 821, The BPA in Food Packaging Right to

Know Act was recently introduced into Congress. This Bill would call for a revised safety assessment

for food containers composed in whole or part of BPA. It would also determine if there is reasonable certainty that no harm will come from BPA exposure through food containers or other items.

The Bill also includes an amendment that would place a cautionary label on packaging of products that contain BPA.

Additionally, I propose the following amendment:

Senate Amdt. 922

Description: Amendment sought to develop a fund for further research to better establish the link between BPA and Obesity

Sponsor: Senator Ed Markey

WHAT CAN WE DO? Contact your policy makers to

encourage them to support passage of Senate Bill 821.
