Bisphenol a


Drinking clean, clear spring water is one of the best things you can do for your health.

But there may be danger lurking in the container.

A recent study published in Toxicology Letters found that polycarbonate water bottles, exposed to regular conditions, contain harmful levels of bisphenol A (BPA).

Bisphenol A is an endocrine disruptor that acts like estrogen in the body, triggering hormonal changes and encouraging the growth of breast and prostate cancers.

While you can keep your bottles cool after you’ve purchased them, there’s no knowing their past history of heat exposure or storage time—which also affects the amount of BPA that leaches into the water.

But that’s not the only place you’ll find this harmful substance lurking. It’s also found in the lining of most canned goods (it helps prevent acidic veggies and fruits from eroding the container).

In 2004, the Centers for Disease Control and Prevention (CDC) found that 95% of Americans have BPA in their urine. Almost all exposure is through diet, and infants fed with liquid formula are among the most exposed.

Banish BPA in Your Body!

You can limit or eliminate your exposure to BPA follow these simple guidelines:

  • Avoid bottles with recycling number 7, as most contain BPA. Instead, opt for recycling numbers 2 and 4 or cloudy-colored plastics which are usually free of BPA. Water packaged in containers made from corn are BPA-free and also biodegradable.
  • Use a high quality reverse osmosis purification system (which also removes other contaminants), and store your water in glass bottles in the refrigerator.
  • Use glass or stainless steel baby bottles (best choice). Plastic bag inserts made of polyethylene, or polypropylene bottles labeled as #5 which are milky, not clear, do not contain BPA.
  • Choose Eden Foods canned goods—they’re packed in lead free tin covered steel cans coated with a baked on oleoresinous c-enamel lining that does not contain bisphenol-A (BPA).
  • Choose soups, broth and milks packaged in cardboard “bricks” by Tetra-Pak and SIG Combibloc which are made of safe layers of polyethylene (#2) and are also recyclable.
