More on Bisphenol A and food.
April 25, 2016 Admin 0
Back in March 2013 we looked at water from different sources, in particular, tap, bottled and filtered. The original article can be found here. Within the article, something known as ‘Bisphenol A’ was brought up. Bisphenol A is an organic compound that exhibits hormone like properties. It’s existence in plastic products is a bi-product of how they are manufactured, although it is less of a concern for one use bottles, such as those you might purchase spring water in. In sports bottles or childrens water bottles that are re-used and also likely to be cleaned regularly is where the most concern should be placed. Regular activities like applying heat, scrubbing or even general washing causes Bisphenol A (also sometimes referred to as BPA) to be released.
The most serious aspect of BPA activity in these containers is its ability to act as an endocrine system disruptor. In essence, BPA can alter the function of the endocrine system by mimicking the role of other hormones. This can be accomplished at even ultra low doses and exposures. Alarmingly, before it was discovered it could be used in polycarbonate manufacture, BPA was used as a synthetic oestrogen. One of the most notable events in BPA’s history occured in 2012 when the American FDA banned its use in baby bottles.
Avoiding exposure to BPA, just like trying to avoid things like nitrites and fluoride can be particularly tricky. The guidelines for eliminating it from possible consumption centre round primarily avoiding plastic products which contain it. In many products, particularly of note, sports bottles are commonly displaying the ‘BPA free’ logo…but may have instead been created with Bisphenol-S and alternative plasticizer, also thought to work as an endocrine disruptor.
Using bottles made from aluminium is one viable alternative that is easy to implement. The second is avoiding canned foods which are lined with BPA resin liners. These are particularly an issue as the retort process (part of the canning heat process) has already applied extensive heat to the plastic liner. Not all canned product contain BPA containing plastic liners either…which can make identifying products tricky, short of taking a can opener shopping and doing some investigative research..
Not re-using plastic water bottles like those you may purchase mineral water in. Some parents also sent their children to school using small spring water bottles instead of a dedicated water bottle. Adding acidic fruit cordials (besides being junk in themselves) may also exacerbate the levels of BPA leaching into the water.
Products marked as BPA free (such as the one in the picture) are likely to have been created with BPS so in all estimation offer the same health risks as BPA. All cooking should be done with porcelain, glass or metal containers. If you are cooking in plastic containers that means you are probably microwaving products which constitute junk anyway..so you have that to evaluate as well as avoiding Bisphenols.
