WASHINGTON — Male mice who were exposed as babies to BPA, a chemical common in canned foods and plastic containers, act more like females and are seen as less desirable mates, a US study showed Monday.

The findings could have implications for how BPA, or Bisphenol A, may affect human development and behavior, said the study published in the Proceedings of the National Academy of Sciences.

“The BPA-exposed deer mice in our study look normal; there is nothing obviously wrong with them. Yet, they are clearly different,” said lead author Cheryl Rosenfeld at the University of Missouri.

“Females do not want to mate with BPA-exposed male deer mice, and BPA-exposed males perform worse on spatial navigation tasks that assess their ability to find female partners in the wild.”

Mother deer mice were fed a diet with levels of BPA that were proportional to the amount the US government considers safe for pregnant women to ingest.

The lab mice were fed this diet for two weeks prior to breeding and throughout lactation.

After their babies were weaned, the offspring were fed a BPA-free diet and Read more…

Untested nanoparticles showing up in thousands of consumer products

(NaturalNews) Since 2006, the use of nanoparticles in consumer products has skyrocketed by over 600 percent. Nanotechnologies, which involve the manipulation of elements and other matter on the atomic and molecular scale, are now used in over 1,300 commercial and consumer products. And that number is expected to jump nearly three-fold by 2020. But are these nanoparticles safe for humans and the environment, particularly when used in food-related applications?

According to data provided by the Project on Emerging Nanotechnologies (PEN), a group formed in 2005 for the purpose of “creat[ing] an active public and policy dialogue” on nanotechnology, nanoparticles are now used in everything from car batteries and appliances, to aluminum foil and non-stick cookware. The “Food and Beverage” section of PEN even includes various vitamin and mineral supplements that contain nanoparticles, as well as McDonald’s Read more…
