I really wanted to share this Blog post so I could ridicule it, but I like the person who posted it to her Facebook, and don't want to hurt her feelings by giving it the raking over the coals that it deserves. I politely pointed out some logical errors in it, but really want to pass the link on to Skeptic friend who would have a field day, and this is the next best thing.

The woman is going after Dasani Water, claiming that the mineral additives in it are teratogenic (cause birth defects), and telling pregnant women not to drink it.

What I find really upsetting about this blog post is that in the comments a new mother talks about how she drank Dasani during her pregnancy and her child was born with a heart defect, and she's wondering if the water did it. Not only is this blogger piling on inaccurate information (and saying silly things when she is challenged by medical professionals) she is upsetting other people. Not cool.

So first off, the blogger says that Magnesium Sulfate is classified as a class D teratogen by the FDA. While this is technically true, the FDA made this classification in the context of women being given injections of magnesium sulfate to stop preterm labour over a period of 5 to 7 days. We're talking a much greater dose than you're going to get by drinking bottled water. When a paramedic challenged the blogger in the comments, he told the blogger that they're talking about doses of 30 grams a day. The blogger responded by saying that Coke doesn't tell us how much magnesium sulfate is in Dasani water. For those needing the conversion, 30 grams is roughly an ounce. (I don't know about you, but I think that Coke isn't using anywhere near that much.)

FDA's info is here:

Next ingredient. Potassium Chloride. The blogger claims it is a problem because it is sometimes used in lethal injections and to stop the heart of a fetus in late term abortions. The stupid, it burns! The blogger doesn't seem to understand the role of dosing, or the fact ingesting a substance is very different than injecting it. The LD50 for Potassium Chloride is roughly the same as the LD50 for table salt.

I wonder if the blogger realizes that Pedialyte, the stuff that they make to give to kids with diarrhea, contains Potassium Chloride? Better not say anything, lest this blog start crusading against it.

Then they complain about the trace amount of salt, saying that if you drink 6-7 bottles of this stuff a day, it would start to add up.

Unhuh. And there's probably going to be traces of salt in any bottled water you drink.
