The BPA-free trend started after studies found a link between bisphenol A (BPA) and health issues such as early puberty and prostate cancers. After that, products with bisphenol S (BPS) started cropping up as a safer alternative. But now a UCLA-led study suggests that BPS can be only as harmful as BPA, causing faster embryonic development and disruption of the reproductive process in animals.
The study is the initially to appear into the influence that BPA and BPS can have on the brain cells and genes linked to the development of reproduction organs. To test the chemicals, the researchers exposed zebrafish, whose transparent embryos manufacture it simpler to watch cell growth, to quite tiny amounts of either BPA or BPS. Applying fluorescent-green protein tags, they were able-bodied to track the development of the animals’ reproductive endocrine brain cells, that control puberty and fertility.
In both cases they observed changes in physiology at the embryonic stage inside 25 hours. They found that the number of endocrine neurons increased up to 40 percent, that suggests that BPA overstimulates the reproductive process actually in cases of low-expocertain.
“Egg-hatching time accelerated, major to premature birth,” says lead study author Nancy Wayne. “The embryos created much faster than normal in the presence of BPA or BPS.”
The research may assist scientists advantageous know the supposed link between endocrine-disrupting chemicals and the rise in premature human births and early onset of puberty over the past couple of decades in the U.S. The findings seem to assist the hypothesis as the team found that both BPA and BPS manufacture their injure through an estrogen process and a thyroid hormone process. Thyroid hormone plays an significant role in brain development during pregnancy.
The question that remains now is how to avoid those chemicals since plastic objects that contain them, such as baby bottles, food storage space containers and plastic table-bodiedware, are equitewhere around us.
“I advise folks to avoid plastic whenever it is actually in your control to do so. I changed my behavior in 2007, when I initially saw the results of our earlier work on the influence of BPA on early embryonic development,” Wayne tells Gizmag. “I threw out all plastic containers utilized for storing food. Ever since, I have been storing food in glass containers. Glass, stainless steel, and ceramic (manufacture certain there’s no lead in the glaze) are great alternatives. The caveat is that they’re heavier than plastic, and glass and ceramic are breakable-bodied – that can cause another set of problems.”
The study appeared in the February 01 version of the journal Endocrinology.
