Which water bottles are the safest?
I saw a good FB post on wastage of water bottles this morning and was about to share….4 hours later! I have more info than will fit in FB so decided on a quick Blog Post.
Which water bottles are safest?
notice the glass bottle…well it is Friday!!
Regular bought water bottles
– (with recycle #1) are questionable and should not be reused with studies showing leaching of phthalate *. Also avoid re using drink bottles that have the recycling codes of 3 or 7, PVC (3) and polycarbonate (polycarbonate bottles are claimed as safe reusable plastic but there is still queries on BPA ** leaching).
*** BPA free bottles
– the best plastic bottles to use and reuse are apparently those with the recycling codes 2, 4 and 5. 2 and 4 (made from polyethylene) and 5 (made from polypropylene). However I found conflicting info saying new evidence suggests that PET, or polyethylene terephthalate, may not be not so benign after all finding leaching of estrogenic compounds.
*** Aluminum bottles
– choose a good quality one as there is still chance of aluminium leaching and some may still have BPA in lining
***** Glass
– wonderful, but not really practical is it?
***** Stainless Steel bottles
– are definitely the best option as they will not leach harmful BPA
or aluminium.
* Phthalates can disrupt your endocrine system and potentially create hormone imbalances.
** Bisphenol A (BPA): Animals studies have shown it interferes with the reproductive development and has been indicated as a causative factor of cardiovascular disease, obesity, diabetes, ADHD, brain and behaviour problems, hormone levels and diabetes.
