Bottled waters have grown steadily in popularity. Some people think they are purer than tap water, while others simply like the convenience of grabbing a drink on the go. However, there are some health concerns with the use of plastic for beverage bottles and food containers. One reason for concern is that some plastics contain BPA, a chemical that can leach into food and drinks when plastics are softened by heat. Therefore, many consumers want to find BPA free bottled water brands.
The proper chemical name is bisphenol A, a component of polycarbonate plastics and epoxy resins. Polycarbonates are commonly used in food packaging. Epoxy resins are used to line metal cans and bottle tops. The lining prevents the metal from reacting with foods or liquids. However, many health researchers caution against using polycarbonates in products like baby bottles, and studies show that chemical taints may leach into canned foods from the protective resin lining.
Although the fact that this chemical can leach into food and liquids is known, the FDA (the regulatory agency for the US food and pharmaceutical industry) does not feel that the levels of contamination are high enough to pose a threat to human health. However, other health experts feel that unborn and very young children can be harmed by any level of BPA.
While the FDA continues its investigation of this chemical, it has published guidelines to limiting exposure to the chemical. Tips include warnings about putting plastic food containers in the microwave or in the dishwasher, since high heat can cause the plastic to break down. Another suggestion is to limit the use of canned goods.
Bisphenol A is an estrogen mimic which can be retained in the human body, where it may increase cancer risks. Researchers have found links to brain and prostate gland development problems in unborn children and infants. For this reason, many people want to avoid this chemical altogether.
There are many BPA-free products on the market. BPA-free baby bottles, teething rings, pacifiers, and 'sippy cups' are now available. As far as bottled waters are concerned, there is a way for consumers to check. Any bottle or container with the recycling code 7 on the bottom is made of polycarbonate and thus could contain bisphenol A.
There are many portable drinking bottles on the market that are not made of plastic. However, those who value the convenience of buying drinks off the shelf may have difficulty in finding information on the chemical composition of bottles. Consumers can check the code number on the bottom of plastic containers. The numbers 2, 4, and 5 designate plastics free of bisphenol A. The number 1 means that the bottle is designed for one use and should not be re-used.
If you want to make sure about a commercial brand, call the manufacturer directly and ask a customer service representative. The representative will be glad to tell you if the manufacturer's bottles are in fact BPA-free. Otherwise you can minimize exposure by using glass, stainless steel, or porcelain food and beverage containers.
