Bisphenol A Dangers were Known before 2003

* Update - Jan. 22. This issue has been broadcast on CBC's Here & Now Monday & Tuesday. It is good to see it becoming more public knowledge. Evening news broadcasts could easily devote a section of their hour long formats to health news/consumer alerts or health education.

You really have to question all plastics, and can liners, or avoid them as much as possible. Check the number at the bottom of bottles and avoid # 7 bottles for sure!

Even five years ago, there were already 40 studies that polycarbonate plastics containing Bisphenol A (BHA) were dangerous. In 2003, it was known that exposure to low amounts of BHA caused genetic defects in mice. In fact, in a major study by Dr. Patricia Hunt & colleagues, mice drank from old baby bottles, that leached (BPA) into their systems. Damage occurred in the egg cells of female mice. Hunt explained, "so when the cells divide, their chromosomes don't line up...In humans, this results in spontaneous abortion, birth defects, or mental retardation."

Other experts were quoted in the same article mentioned above. Biologist Frederick S. von Saal has studied BPA for many years, and had this to add:

In a recent study, fetal umbilical blood shows higher BPA levels than we generated in mice. Human exposure levels are already high. The horrifying thing is that it looks as though these effects in the Hunt study happen at lower doses than what is actually found in human fetal blood - umbilical cord blood.

What about other plastic compounds? Another plastic compound called Antimony, used in PET bottles, has been and is being studied for its potential hazardous effects. How many others are unsafe, and are years aways from garnering the danger status of BPA?

There are food containers of every shape and size that millions use all their lives. Bisphenol A, and any other plastic compound may very well have contributed to a variety of health problems, including prostate enlargement and cancer, and breast cancer because it has been seeping into food and liquid.

The bottling industry has carried out their own studies, and guess what, they have not found any harmful effects from BPA, despite 90% of 150 independent studies which says otherwise. I guess that unless you want to be fired, industry sponsored research designs will have predictable outcomes.
