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.

I have a stainless steel bottle. Probably okay?

I switched to stainless steel years ago as well. I realize that with plastic bottles the concern was that BPA would leach into the water over time, and that using something like a Nalgene bottle occasionally is no big deal. However, I drink primarily water, and I carry a 40z bottle of it with me all day every day, so I figured why not play it safe and just avoid plastic. The stainless steel bottles are durable and reasonably priced.

Metal containers have a plastic lining inside. If you expose the metal to the liquid, it starts to corrode (yes even stainless steel will corrode), and atoms of the metal and its oxide float off in the water. This is also true of aluminum soda cans. There's a plastic lining on the inside. If you're handy with a knife, you can cut a can in half and peel off the plastic to see for yourself.

So your choices are pretty much glass with its fragility and breakage problems, or metal/plastic with the BPA/BPS scare. Or you can accept that the environment is trying to kill you, decide to live with the small risk, and enjoy life instead of worrying about every little thing. If there's a big risk, it'll be established pretty quickly (e.g. ozone depletion, thalidomide). If something is classified as "may be a risk" for decades, that's a pretty good indicator that the risk, if there even is one, is very small.

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!

And if the sarcasm of my previous statement didn't ring loud as a bell, let me be direct.

The mentality your entire statement just suggested is little more the irresponsible, half-witted nonsense and makes you look like a dolt spouting retarded gibberish. My 6 year old has better common sense than you have displayed.

Probably not. Everything is killing you.

Everyone who has drank water has died.

mmm... I haven't died, just not yet =P. Would be more correct to state that everybody who has died drank water... yet not entirely truth
