According to experts there is no harm in handling products made of BPA; however scientists have linked the synthetic compound to a host of human diseases, particularly where it has been in contact with food and drink. As a result, most people have started using BPA free drink bottles and avoiding their polycarbonate counterparts. This has especially been a trend in the baby bottle market where children are more susceptible to the effects of BPA.
Tests conducted on rats found that BPA acts as an endocrine disruptor that majorly mimics the rats own hormones, such as oestrogen. This endocrine disruptor is also responsible for several adverse biological effects like possible neurotoxicity, carcinogenic effects and development of increased toxicity. The plastic, which is known as the polyethylene terephthalate (PET or PETE), has become an ideal for those who prefer to use BPA free drink bottles.
More recently, the trend has been away from plastic drink bottles towards BPA free stainless steel drink bottles. This has been predominately due to the fear of BPA and the risks posed by other harmful chemicals potentially leaching from the inner walls of BPA free plastic drink bottles. Similarly, aluminium drink bottles (lined with epoxy resin to prevent aluminium contamination) have also reduced in use due to the risks associated with BPA and the leaching other harmful chemicals. Stainless steel poses no risk from metal contamination due to its hygienic properties, and therefore requires no inner-lining and no BPA, placing it as the leading BPA free drink bottles on the market today.
