Is Your Bottled Water Safe?

Does your water bottle contain Bisphenol-A or BPA? This chemical is used in some plastics, including food packaging... and research shows it can leach into the products inside.

Drinking enough water is essential for hydration, energy level and can even boost metabolism. But if you're carting around your water in a plastic water bottle, you'll want to make sure it's BPA-free. BPA is a chemical used to harden plastics, and it is found in food and drink packaging like water and infant bottles and used to coat metal in food cans and bottle tops.

The amount of BPA that leaches into food can largely depend on the temperature of the liquid or bottle. If BPA leaches into your water, it could disrupt the endocrine system which can put you at risk for certain cancers and increase your risk of obesity. A national health survey conducted by the Centers for Disease Control and Prevention (CDC) revealed that human exposure to BPA is widespread, with 93 percent of samples showing detectable levels in the body.

If you're not sure about disposable water bottles, flip it over and look at the bottom. There is a number down there, and you'll want to avoid ones with the number seven, because that one has the most risk of containing BPA.
