Don’t Drink bottled water! At least on a daily basis.

Think bottled water is cleaner than from the tap? Think twice! Beware of Bisphenol A!

What is Bisphenol A?

Bisphenol A (BPA) is an industrial chemical used to make a hard, clear plastic known as polycarbonate, which is used in many consumer products, including water bottles, baby bottles and as coatings on the inside of many food and beverage cans.

Bisphenol A is an endocrine disruptor that can mimic estrogen and has been shown to cause negative health effects in animal studies.

Bisphenol is found in 96% of pregnant women!

Regulatory authorities of many countries consider that BPA does not pose a risk to the general population. Consumers can continue to use polycarbonate water bottles and consume canned foods and beverages, as the level of exposure from these products is very low.

Is it really so? Or it’s just about protecting mega-bucks businesses?

Although regulatory bodies have determined safety levels for humans, those safety levels are currently being questioned or are under review as a result of new scientific studies. A 2011 study that investigated the number of chemicals pregnant women are exposed to in the U.S. found BPA in 96% of women.

There is a special concern about baby bottles. The European Union and Canada have banned BPA use in baby bottles and infant formula packaging. The Government of Canada is moving forward with legislation to ban the importation, sale and advertising of polycarbonate baby bottles.

Bisphenol concentration depends on time of storage and the temperature.

One more thing you have to know about: the BPA concentration in the bottled water depends mainly on two factors – time of storage and the temperature. The more time water was kept in the polycarbonate bottle the higher the BPA level; and the higher the temperature the faster BPA extraction. That’s why it’s recommended that parents and caregivers do not put very hot/boiling water in polycarbonate baby bottles, as very hot water causes BPA to migrate out of the bottle at a much higher rate.

Now, LOOK AT JAPAN: Between 1998 and 2003, the Japanese canning industry voluntarily replaced its BPA-containing epoxy resin can liners with BPA-free polyethylene terephthalate in many of its products. For other products, it switched to a different epoxy lining that yielded much less migration of BPA into food than the previously used resin. In addition, polycarbonate tableware for school lunches was replaced by BPA-free plastics. As a result of these changes, Japanese risk assessors have found that virtually no BPA is detectable in canned foods or drinks, and blood levels of BPA in the Japanese people have declined up to 50% in one study.

So, the question is – to drink or not to drink bottled water on a daily basis? It’s up to you.

But maybe better safe than sorry?
