Safe Drinking Bottles

May 13, 2010

More and more people are becoming aware of a chemical called Bisphenol A (BPA).  It is used in the production of polycarbonate plastics which are clear and nearly shatter-proof, in particular babies bottles and plastic mineral water bottles.  It is also present in toys, the lining of some food cans and dental sealants.

With bottles, the concern is that BPA can leach into the contents when heated or when the plastic becomes old and gets scratched.  Sheryl Crow is convinced she got breast cancer because she used to drink water from bottles left in her car which had heated up in the sun.

BPA can mimic the effect of the hormone oestrogen in the body.  Animal studies have shown it affects reproductive, neurological and immune systems.  Babies are particularly vulnerable to hormone mimicking effects because they grow rapidly, both in the womb and in their early months and years.

The National Childbirth Trust advises parents to adopt the precautionary principle and avoid bottles containing BPA.  Read their factsheet http://www.nctpregnancyandbabycare.com/info-centre/information/view-119 to find out how to choose the safest bottle for a baby.  Bottles with BPA have already been banned in Canada and are in the process of being withdrawn in the US.

Breast Cancer UK have launched a campaign, No More BPA, to draw attention to the potential harmful effects of BPA as a hormone mimic to human health.  The charity has put together a detailed report on the effects of Bisphenol A on the hormone system and, in particular, in connection with breast cancer risk.  You can read more about the campaign and download/read the report at the dedicated website http://www.nomorebpa.org.uk.

It is possible to buy bottles without BPA (the Sistema range available from Lakeland for example).  Most bottles have a number in the recycling symbol on the bottom and the numbers which are safer are 1 or PETE/PET, 2 or HDPE, 4 or LDPE and 5 PP.  Avoid 3, 6 and 7.
