bone loss and de-mineralized water (like reverse osmosis)?

peggy_j

Has anyone heard that there may be a link between low bone mass and demineralized water (like reverse osmosis)?

I was surprised to learn that my town, like many in the US, has Chromium-6 in our water (the chemical highlighted in "Erin Brockovich." Is this news? How did I miss this?)

So now I'm thinking of getting something better than Brita. But the WHO has issued a study about the health risks of drinking demineralized water (like Reverse osmosis or Zero Water ion exchange system). They claim that since the water has no minerals, not only do we lose the amount we'd get in mineralized water, but that demineralized water leaches those minerals from the food when cooked (they claim up to 60%). This report talks about other risks too.(which I haven't had time to research/verify).

Has anyone found a filter system they like that gets out the nasty stuff but keeps the calcium and magnesium?

There's an Aquagear pitched claims to do this:

(but it's slow and $). Any others?

Just wondering if you have any thoughts and what systems you use.

ETA: this system claims to remove Chromium-6 and a bunch of drugs too.

As an FYI, I've continued to do research. I'm not comfortable going with RO, since the WHO issued those health risks with de-mineralized water. I'm going to stick with carbon filter. But are all carbon filter systems the same? Apparently not. I noticed that some of the PUR filters (model CRF-950) also filter our Rx drugs and BPA. here's a list of the certification.

They sort the products by the class of NSF certification. BPA is listed under NSF/ANSI 401 (near the end)

Those other brands I mentioned initially are not NSF certified. I emailed asked why and they said they haven't gone through the process yet (too much $ or lazy or their product makes claims they can't support? I have no idea). Anyway, my decision at this point is PUR pitcher with that good filter. If you have other info or thoughts, please let me know.

Interesting stuff - I wish others would chime in!!  Thanks for posting!

Thanks Denise. Yeah, I'd be curious to know what other people think and have read.Anyone else have thoughts?

BTW, the NSF lists the PUR filters under Kaz, their parent company. But if you google on the model number you can find the right product. It seems like the key is getting the right filter. The size of pitcher/etc doesn't matter.
