So, what does this say from above source? Quote: t thus appears that IIH can be considered one of the iodine deficiency disorders, and it may be largely unavoidable in the early phase of iodine repletion in iodine deficient populations, particularly in those with moderate to severe iodine deficiency. Its incidence reverts to normal or even below normal after one to ten years of iodine supplementation (196).
I read that as a lot of iodine all at once in iodine deprived individuals can cause havoc until iodine sufficiency (over 10 years) is obtained. As for the rest of the article, it's mainly talking about autoimmune thyroiditis, with effects occuring mainly in PREVIOUSLY IODINE DEFICIENT subjects. Hmmmm. Then it discusses cancer. And I do understand their overall conclusions: Quote: . The frequency of cytologically diagnosed chronic thyroiditis increased from 1.5 to 5.7% (214). Overall, it appears that correction of iodine deficiency decreases the risk of, and the morbidity from, thyroid cancer.
Thus, the benefits of correcting iodine deficiency far outweigh its risks (215, 216). Iodine-induced hyperthyroidism and other adverse effects can be almost entirely avoided by adequate and sustained quality assurance and monitoring of iodine supplementation which should also confirm adequate iodine intake. Endquote.
I guess the only real bone of contention here are the amounts given. (10 years to recover from deficiency and let iodine supplementation settle into acceptable levels??? I'm sorry, but I doubt if I can spare a decade at my age.)
[QUOTE=Pamsc;911793]I haven't looked at all of these, but those I looked at don't leave me overly concerned. Many involve much more dangerous forms of iodine, like amiodarone. Others involve iodine causing (or exacerbating) autoimmune thyroid damage, which we know can happen if you take iodine without selenium. The Peace Corps workers were in Niger, which a quick google search suggests is an area of low selenium.[/QUOTE]
Talking about dangerous forms of iodine, look what's happening in Fukashima now: quote:
Accordingly, how can anyone estimate long term health effects when actual exposure rates are unknown?
That said, scientists do have a well defined test group – the population of Fukushima Prefecture surrounding the stricken NPP.
And the sixth report of the Fukushima Prefecture Health Management Survey, which was released in April, revealed after the survey examined 38,114 local children that 36 percent of Fukushima children have abnormal thyroid growths.
The Fukushima Prefecture Health Management Survey revealed that 13,460 children, or 35.3 percent, had thyroid cysts or nodules up to 0.197 inches long growing on their thyroids and 0.5 percent of the children had growths larger than 0.197 inches. Endquote Radioactive iodine, anyone? from Oilprice.com
I'd suggest reading further down the first study to the human toxicity section ([url=http://ebm.rsmjournals.com/content/229/6/473.full#sec-3):]Iodine Toxicity and Its Amelioration[/url]
"Well over half of adult I goiter patients have been found to ingest inorganic I for a prolonged period, with daily amounts ranging from 18 mg to 1 g (6). Withdrawal of I in these people usually produces a return to the euthyroid condition, and reintroduction of KI generally causes both goiter and hypothyroidism to reappear within 3 weeks (29, 30). Wolff (6) concluded that the relatively rapid reappearance of goiter after reintroduction of I therapy may be the most conclusive test of whether the goiter was, in fact, caused by excess I ingestion. "
"A daily I intake of 10 times (i.e., 1.5 mg/day) the minimum daily adult requirement of 0.15 mg/d may cause I goiter in some people (6)."
For the study of the Japanese children, please see the discussion section of the full text for a more in-depth explanation ([url=http://www.ajcn.org/content/81/4/840.full#sec-7]High thyroid volume in children with excess dietary iodine intakes[/url]).
Goiter simply means an enlarged thyroid, which may occur in hyperthyroidism or hypothyroidism.[/QUOTE]
The Wolff-Chaikoff effect was first postulated in 1948. Since then, there have been numerous studies, including this one from Endocrinology 1999, that show the effect is transient. In this article, titled "Escape from Wolff-Chaikoff, here are their conclusions: Quote: Hashimoto’s
In summary, we have shown that excess iodide, given to
rats, chronically or acutely decreases both thyroid NIS
mRNA and protein. Our findings are consistent with the
hypothesis that the escape from the Wolff-Chaikoff effect is
caused by a down-regulation of the NIS, resulting in decreased
iodide transport into the thyroid. This would then
lower the intrathyroidal iodine below a critical threshold and
would allow organification to resume. The decrease in NIS
is likely to be, at least in part, transcriptional. In addition, we
have also found that excess iodide decreases TPOmRNAand
that this decrease may contribute to iodide-induced hypothyroidism
commonly seen in patients with Hashimotos’s
I dunno, seems like the hypothesis doesn't stand up to experimentation, and that the rats would have recovered in 6 days even with excess iodide (not simply iodine.) And on my ramblings, I read that one doctor never sees any problems arising with 9 drops iodine or less daily. Nor was I able to discern whether this was 2 or 5% Lugols. Nevertheless, I have scaled back my iodine intake to control detox symptoms.
Thanks for the Seasnax tip, PaleoBird. I've recently gotten hooked on the Trader Joe's seaweed snacks but I didn't feel totally good about it because I believe they use an offensive oil for roasting. I will be ordering some of these!
[QUOTE=Knifegill;911557]I have fluoride-free toothpaste (available at any Super Supplements), and I do not drink tap water. I drive to the well to fill my 14 5 gallon bottles every month. And I do not ingest any bromide, either. THAT is the solution. Stop the poisoning and - amazingly - you stop needing an antidote. Imagine that![/QUOTE]
Interestingly, at least one of the celtic sea salts I looked at lately listed bromide in the list of minerals it contained.
[QUOTE=Grizz;911581]I think the Nit Pickers are all LIBERALS. The Hallmark of a LIBERAL is they demand that everyone do it THEIR way.
For example, the conservative who doesn't like guns just doesn't buy a gun.
The LIBERALS demand gun laws to prevent anyone from buying a gun.
Conservatives who don't like Big Gulp Sugary drinks just don't drink them.
Liberals pas laws to prevent EVERYONE from drinking Big Gulp Sugary drinks.
Conservatives who don't like iodine just don't take it.
Liberals try to outlaw iodine so NO ONE can have it.[/QUOTE]
The Liberal/Conservative divide is a false dichotomy which doesn't really help anyone. It fosters stereotypes that help political parties to hide behind labels while acting in ways that are harmful to most of those who voted for them, and causes needless divisions amongst those who should have common cause.

That's because bromide is one of the minerals found naturally in seawater.

They are so tasty. I got them from an online site called Netrition.com which also carries Sea Tangle brand kelp noodles. Three ingredients, kelp, water, and salt. I made some for dinner tonight. (pics on my journal momentarily)
Netrition.com also carries a lot of great coconut products and all at better prices than the local health food store. (No, I don't work for them.)

Love the sound of Seasnax and Sea Tangle kelp noodles. Do you happen to know if they ship to the UK? I'd far prefer to eat sea veg than to take iodine sups...
