It seems like the more we learn the more unsafe the products our children touch everyday. Now the latest issue is Bisphenol-A and possibly other chemicals that plastic containers may leech into their drink and food items.

After Ji Seon did a considerable amount of research on this topic we have decided to use as little as possible any plastic but especially plastics that are not type 2, 4, or 5. We are trying to use glass or stainless steel as much as possible. Anybody want some Nalgene bottles? 😉

Here is one article that we felt was balanced and informative.

The Bisphenol-A Debate: A Suspect Chemical in Plastic Bottles and Cans
By Catherine Zandonella, M.P.H

According to its critics, BPA mimics naturally occurring estrogen, a hormone that is part of the endocrine system, the body’s finely tuned messaging service. “These hormones control the development of the brain, the reproductive system and many other systems in the developing fetus,” says Frederick vom Saal, Ph.D., a developmental biologist at the University of Missouri. Endocrine-disrupting chemicals can duplicate, block or exaggerate hormonal responses. “The most harm is to the unborn or newborn child,” vom Saal says.

Ninety-five percent of Americans were found to have the chemical in their urine in a 2004 biomonitoring study by the Centers for Disease Control and Prevention (CDC).

However, when it comes to hormone disruption, different doses can activate or suppress different genes, vom Saal explains. “That’s why early toxicity studies found that the high doses were safe. The studies didn’t look at the low doses that are now proving to cause a myriad of harmful effects in animals, including chromosomal damage in female egg cells and an increase in embryonic death in mice. A follow-up to this is a study indicating a relationship of BPA blood levels to miscarriages in Japanese women,” he says.

Vom Saal counters that the studies showing BPA is safe are “profoundly flawed and in some cases exhibit outright fraud.” Last year, he published a paper showing that 100 percent of the industry-funded studies, 11 in all, found no harmful effects from BPA, while 90 percent of government-funded low-dose studies, 104 in number, found harmful effects. “Among people who have actually read this literature there is no debate, just an illusion of controversy,” he says.

A January 2006 study indicates that BPA may enhance the risk of developing Type II diabetes.

One study linked women with ovarian disfunction to elevated blood levels of BPA, and another found that blood levels of BPA were three times higher in women who’d suffered recurrent miscarriages than in women with successful pregnancies.

This is very interesting. How do these water bottles still get approved? I would think they would be pulled off the shelves already?

P.S. Nice blog layour
