NATIONAL ACADEMY OF SCIENCES PUBLISHES POLITICALLY INCORRECT PERCHLORATE STUDY

  You probably won't read about this in mainstream media outlets such as The New York Times, the Washington Post or The Los Angeles Times, but lookey here:  on October 31, 2005 the prestigious National Academy of Sciences published on line a study concluding:

Perchlorate is a goitrogenic anion that competitively inhibits the sodium iodide transporter and has been detected in forages and in commercial milk throughout the U.S. The fate of perchlorate and its effect on animal health were studied in lactating cows, ruminally infused with perchlorate for 5 weeks. Milk perchlorate levels were highly correlated with perchlorate intake, but milk iodine was unaffected, and there were no demonstrable health effects. We provide evidence that up to 80% of dietary perchlorate was metabolized, most likely in the rumen, which would provide cattle with a degree of refractoriness to perchlorate. Data presented are important for assessing the environmental impact on perchlorate concentrations in milk and potential for relevance to human health. 

^***

^{A  60-kg pregnant woman could consume in excess of 3.7 liters of milk containing 11.3 ng of perchlorate per ml without exceeding the RfD, and this quantity of milk would be well in excess of average daily consumption.}

^{(emphases added).}

    ^{Don't hold your breath waiting to hear our legislators and regulators cite this study as at least some evidence that caution is needed in allocating scarce resources to perhaps more pressing problems.  In environmental politics, the keyword remains politics.}

Oh my god, Elea, that is insane. I'm so sorry you had such a shit time with the meadiction you'd think the doctors would listen to you when you say, No, every time I take this my airways close up. Seems to me that's a crucial component of, I don't know, continuing to be alive? I could see them prescribing an anti-anxiety med if they thought you were having panic attacks, but TELLING you it was an anti-anxiety instead of lying to you that it was a muscle relaxant. How positively frustrating. Here's hoping they work it out. It's got to be so scary not knowing what the matter is.

Christy It's good to get a real testimony in here about the WAPF hoeadmme formula. I never made it (thankfully both my boys were/are excellent at breastfeeding and I've never had to interrupt it for any health concerns), but from what I hear your story is common. It's a bid intimidating at first, but soooo worth it and even easy once you get the hang of it.Patricia Yes, I've encountered that defensiveness, too, with a lot of women. I wholeheartedly believe EVERY mother is trying to do what's best for their kids with the resources they've got, so when I speak about other alternatives I'm in no way judging the moms who chose to do things differently! I wouldn't beat yourself up over the past. Seriously! I'm *amazed* you pumped for 9 months. I'm fortunate enough to work from home, so I never had to pump. I have nothing but respect and amazement for the women who do, and wonder if I'd have the same endurance if it were me.

Error in my previous comment: It's regulators in New Jersey, not New York, that recommend a drinking water standard for perchlorate of 5 ppb based on the NAS reference dose of 23 ppb.

[Larry Ladd]

The NAS also recommended that a survey of perchlorate adhesion to proteins be done. If it turns out that perchlorate adheres more tightly to thyroid hormone receptors or defensins in the innate immune system than to the identified perchlorate target (the sodium iodide symporter), then regulation of perchlorate at the 1 to 6 ppb level is thoroughly justified.

It's known that perchlorate adheres to albumin in the blood, and thereby displaces small amounts of free iodide and thyroid hormone from that protein, before ClO4- affects iodide uptake in the thyroid. There is no measurable blockage of the sodium iodide symporter until perchlorate "saturates" the available sites on albumin in the bloodstream, but that -- rightly I feel --is considered a non-adverse effect. Unfortunately you can't be so sanguine about perchlorate sticking to thyroid hormone receptors (Dr. Thomas Zoeller's pet theory) or defensin (my pet theory). Until those two hypotheses are ruled out, I believe regulators in Massachusetts (1 ppb), New York (5 ppb using the NAS reference dose), and California (6 ppb)are in the right ballpark.
