BPA alternative may cause just as many problems

A little over four years ago, BPA was linked to a number of medical conditions including diabetes, asthma, and cancer among others. The chemical was commercially introduced in 1957, and was used in a wide range of products including food containers and bottles. Due to the backlash over BPA-related health risks, many manufacturers stopped using the chemical in their products.

In response, companies that offered plastic products containing BPA switched to Bisphenol S (BPS). BPA and BPS are very similar structurally, making the latter a good “drop-in replacement” for the former.

Researchers at the University of Texas Medical Branch at Galveston are now reporting that widespread human exposure to BPS was confirmed in 2012 during the analysis of urine samples taken in the U.S., Japan, and China. The research study found that BPS disrupts cellular responses to the hormone estrogen, changing the pattern of cell growth -- even low levels of BPS exposure were enough to interfere with hormones.

"Our studies show that BPS is active at femtomolar to picomolar concentrations just like endogenous hormones -- that's in the range of parts per trillion to quadrillion," said UTMB professor Cheryl Watson, senior author of a paper on the study now online in the advance publications section of Environmental Health Perspectives. "Those are levels likely to be produced by BPS leaching from containers into their contents."

The backlash against BPA was fast and furious, but it may take some more time (and additional studies) to determine if BPS will encounter the same fate.

There is no plastic lining in aluminum cans. Aluminum naturally creates a lining in the form of aluminum oxide upon contact with air. Lining aluminum cans would be costly and redundant. And yes, out of curiosity, I just tried your idea of cutting open a can and "peeling" off the suggested layer. There was none.

And properly made glass is not as fragile as you seem to think.

And oh yes, let us all just live with the un-natural poisons being fed to us by the companies who care more about providing a profit to their share-holders than they do about real safety. What a wonderful mentality! Yes, let's not worry at all about a little bit of poison here, a few chemicals there. After all how much real harm can they do, right? We all might as well just hop in front of a fast moving freight train!
