BPA From Plastics, Food Packaging, Linked To Obesity

Americans may be growing fat not only from the foods we eat, but from the hormone-disrupting materials in which those foods are given to us. Via the Smithsonian:

Since the 1960s, manufacturers have widely used the chemical bisphenol-A (BPA) in plastics and food packaging. A study by researchers from New York University, published today in the Journal of the American Medical Association, looked at a sample of nearly 3,000 children and teens across the country and found a “significant” link between the amount of BPA in their urine and the prevalence of obesity.

The researchers speculate on a possible underlying mechanism, alluding to other studies that have shown that the chemical may disrupt mechanisms of human metabolism in ways that increase body mass. They also note studies that have revealed associations between urinary levels of BPA and incidences of adult diabetes, cardiovascular disease and abnormal liver function.

The vast majority of BPA in our bodies comes from ingestion of contaminated food and water. The compound is often used as an internal barrier in food packaging. When heated or washed, plastics containing BPA can break down and release the chemical into the food or liquid they hold. As a result, roughly 93 percent of the U.S. population has detectable levels of BPA in their urine.

    I bought a couple of steel water bottles that I carry around with me.

    I’m not squeamish as a general rule but that plastic shit can’t be good for you.

    did they consider that even though the kids had high levels of bpa, the obesity was due to what foods they were eating as packaged and processed foods that would lead to high levels of bpa are often also very unhealthy.

       that is a good point, and generally they do allow for those kinds of variables.  I read a study on the connection between mental disorders and homosexuals.  Undoubtedly this is riddled with variables but they have summed the idea up well.

      The current study was done in an effort to find out what mechanisms
      (e.g. “minority stress,” environmental factors, and/or genetic factors)
      might likely elevate the psychiatric vulnerability of nonheterosexuals.
      In conducting their literature review, some support was found for a
      “minority stress” hypothesis, however such support was weakened by the
      fact that the relationship between sexual orientation and mental health
      is strong even in socially liberal countries, such as the Netherlands.
