Endocrine Disruptors
Release of Bisphenol A by Polycarbonate Bottles
The study taken on by the Harvard School of Public Health involved 77 students who were first put through a seven day ‘cleansing process’ in which they were given cold drinks that were stored in stainless steel bottles. This limited the amount of BPA they were exposed to.
They were then simply given polycarbonate bottles and were instructed to use them for all their cold drinks for the next week. They were also told to drink from the bottles in a normal way and not to use hot liquids in them in case it caused excessive leaching of BPA which could skew the results.
The Results of the Study
The results were surprisingly clear. The amount of the endocrine disruptor bisphenol A increased by 69% in the urine of those that participated in the experiment after drinking from the polycarbonate bottles.
A substantial body of research is now building up against the potential harmful effects of bisphenol A. In 2008 Canada took a bold step towards eliminating bisphenol A in consumer products by completely banning the use of the chemical in baby bottles. A few manufacturers have also taken steps in the same direction and have reduced the use of BPA in some of their products.

Good tips. You have to make sure that your baby bottles doesn’t contain bisphenol A. Hormone mimicking chemicals affect babies much more than adults.
