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.

Actually sugar has a role to play. When fruits are in season many animals fatten themselves up on it. Then when fruits go out of season or winter comes, they start losing that fat. If they didn't get fat enough they might not do so well.

The main problem I see is if you keep fattening yourself up for years or even decades.

The same faux activism


You mean Science? I thought the other thing was faux activism - Religion? You might notice that those who ignore Science and instead create fictional realities also fall under the Religion spectrum due to their reliance on belief, i.e. make believe, not founded in fact, unscientific.

BPA was subject to a lot of scientific study. After all that study, it was concluded that BPA was probably not a good. Probably not hard to locate the scientific studies. Is that conclusive? Of course, not. Governments took advice from their agencies and the Canadian action probably spooked everything enough to immediately go nuts. Manufacturers replace BPA with BPS - a very similar chemical with similar properties. The scientists are merely proving that BPS has similar risks attached that led to the BPA issues (something the companies involved would already be aware of).

No, they are not proving anything because they failed to prove anything with BPA in the first place. It was junk science with tests designed produce a desired result rather than a legitimate test with an objective analysis of results.
