Maybe it's controversial to some folks, but for those of us using iodine for

cancer, we have the proof in our own bodies. Even the UN is saying that

iodine deficiency is a problem--even in children in Europe for pete's sake.

I enjoy reading Peat's work. He doesn't have any articles listing iodine as

harmful on his

Hey Sandi...I got the articles from another source...I am happy to

email them to you if you contact me offline....If you can

distinguish them in some way from Abraham and Brownstien's (A &

work...I would appreciate it. Peat is adamantly opposed to the use

of iodine...and that troubles me because I respect his work. He

says its best to completely ignore everything that A & B are

reporting. I recently read B's book and Dr. Derry's book on iodine

and found them to be persuasive...I started taking iodorol but

backed off when I got so sleepy I couldn't make it through the day.

Would appreciate any input you have on the sleepiness or other

relevant info.

I know Peat is adamantly against the use of radioactive iodine.

I still haven't been able to find anything written by Peat contradicting the

Shomon: Do you think the majority of people with hypothyroidism

get too much or too little iodine? Should people with hypothyroidism

add more iodine, like kelp, seaweeds, etc.?

Dr. Ray Peat: 30 years ago, it was found that people in the US were

getting about ten times more iodine than they needed. In the

mountains of Mexico and in the Andes, and in a few other remote

places, iodine deficiency still exists. Kelp and other sources of

excess iodine can suppress the thyroid, so they definitely shouldn't

be used to treat hypothyroidism.

both sides are adamant that they are right....its up to us guinea pigs

to sort things out...I have received a lot of email offline indicating

Environmental factors affecting autoimmune thyroid disease.

Safran M, TL, Roti E, Braverman LE.

Department of Medicine, University of Massachusetts Medical Center,

Worcester.

A number of environmental factors affect the incidence and

progression of

autoimmune thyroid disease. Exposure to excess iodine, certain

drugs, infectious

agents and pollutants, and stress have all been implicated.

Science 1985 Oct 18;230(4723):325-7

Induction of autoimmune thyroiditis in chickens by dietary iodine.

Bagchi N, Brown TR, Urdanivia E, Sundick RS.

Clinical studies have suggested that excess dietary iodine promotes

autoimmune

thyroiditis; however, the lack of a suitable animal model has

hampered

investigation of the phenomenon. In this study, different amounts of

potassium

iodide were added to the diets of chicken strains known to be

genetically

susceptible to autoimmune thyroiditis. Administration of iodine

during the first

10 weeks of life increased the incidence of the disease, as

determined by

histology and the measurement of autoantibodies to triiodothyronine,

thyroxine,

and thyroglobulin. Further support for the relation between iodine

and

autoimmune thyroiditis was provided by an experiment in which iodine-

deficient

regimens decreased the incidence of thyroid autoantibodies in a

highly

susceptible strain. These results suggest that excessive consumption

of iodine

in the United States may be responsible for the increased incidence

of

autoimmune thyroiditis.

High thyroid volume in children with excess dietary iodine intakes.

Zimmermann MB, Ito Y, Hess SY, Fujieda K, Molinari L.

Human Nutrition Laboratory, Swiss Federal Institute of Technology,

Zurich,

Switzerland. michael.zimmermann@...

BACKGROUND: There are few data on the adverse effects of chronic

exposure to

high iodine intakes, particularly in children. OBJECTIVE: The

objective of thestudy was to ascertain whether high dietary intakes

of iodine in children result

in high thyroid volume (Tvol), a high risk of goiter, or both.

DESIGN: In an

international sample of 6-12-y-old children (n = 3319) from 5

continents with

iodine intakes ranging from adequate to excessive, Tvol was measured

by

ultrasound, and the urinary iodine (UI) concentration was measured.

Regressions

were done on Tvol and goiter including age, body surface area, sex,

and UI

concentration as covariates. RESULTS: The median UI concentration

ranged from

115 microg/L in central Switzerland to 728 microg/L in coastal

Hokkaido, Japan.

In the entire sample, 31% of children had UI concentrations >300

microg/L, and

11% had UI concentrations >500 microg/L; in coastal Hokkaido, 59%

had UI

concentrations >500 microg/L, and 39% had UI concentrations >1000

microg/L. In

coastal Hokkaido, the mean age- and body surface area-adjusted Tvol

was

approximately 2-fold the mean Tvol from the other sites combined (P

< 0.0001),

and there was a positive correlation between log(UI concentration)

and log(Tvol)

(r = 0.24, P < 0.0001). In the combined sample, after adjustment for

age, sex,

and body surface area, log(Tvol) began to rise at a log(UI

concentration) >2.7,

which, when transformed back to the linear scale, corresponded to a

UI

concentration of approximately 500 microg/L. CONCLUSIONS: Chronic

iodine intakes

approximately twice those recommended-indicated by UI concentrations

in the

range of 300-500 microg/L-do not increase Tvol in children. However,

UI

concentrations >/=500 microg/L are associated with increasing Tvol,

which

reflects the adverse effects of chronic iodine excess.

Multicenter Study

Acta Endocrinol (Copenh) 1978 Aug;88(4):703-12

A case of Hashimoto's thyroiditis with thyroid immunological

abnormality

manifested after habitual ingestion of seaweed.

Okamura K, Inoue K, Omae T.

An interesting case of iodide induced goitre with immunological

abnormalities is

described. The patient who was sensitive to synthetic penicillin had

previously

been treated for exudative pleuritis, congestive heart failure and

acute renal

failure. Following recovery, he began to ingest large amounts of

seaweed after

which he developed goitrous hypothyroidism. It was of interest that

the serum

level of gamma-globulin increased, and subsequently the antithyroid

microsomal

antibody became strongly positive, suggesting that thyroidal

autoimmune

processes had been precipitated. Biopsy of the thyroid gland

revealed chronic

thyroiditis, with evidence suggesting extreme stimulation by TSH.

Hight

thyroidal uptake of 131I, positive perchlorate discharge test and

biochemical

analysis of the thyroidal soluble protein showed severe impairment

of hormone

synthesis following continuous accumulation of excess iodide. While

there is

evidence suggesting that increased iodide may be an important factor

in the

initiation of Hashimoto's thyroiditis, this may result from the

marked increased

sensitivity of Hashimoto's gland to the effects of iodine. Thus an

occult lesion

could be unmasked in this manner. The mechanism by which iodide

mediates this

effect is not clear.

Iodide induced lymphocytic thyroiditis in the BB/W rat: evidence of

direct toxic

effects of iodide on thyroid subcellular structure.

Li M, Boyages SC.

Department of Clinical Endocrinology, Westmead Hospital, NSW,

Australia.

A high dietary iodine intake accelerates the development of

lymphocytic

thyroiditis (LT) in the BB/W rat. Our previous studies have defined

the temporal

sequence of the immunological events triggered by excess iodide

intake in these

animals. It was still not clear, however, whether these observed

immunological

changes were a direct effect on immune effector cells, or whether

they

represented a secondary response to a toxic effect of iodine on

thyroid tissue.

In the present study, the effect of excessive iodine intake on the

subcellular

structure of the BB/W rat thyroid gland, particularly, whether

iodide had a

toxic effect independent of its immune response has been examined.

BB/W rats

were exposed, prenatally through maternal drinking water, to

excessive iodide at

two doses (Moderate 3 x 10(-6) M iodide/l; High 3 x 10(-3) M

iodide/l); a third

group of BB/W rats was given tap water; till 12 weeks postnatal age.

Two groups

of Wistar rats received high dose iodide water or tap water for the

same periodof time and served as controls. Thyroid gland

ultrastructure was determined by

electron microscopic (EM) examination. Thyroid 125I uptake and

perchlorate

discharge tests were also performed in separate experiments. We

found that

thyroid glands of non-iodine supplemented Wistar rats were

morphlogically normal

under EM. There were no overt changes in the iodide treated Wistar

rats. By

contrast, iodide treated BB/W rats exhibited marked accumulation of

secondary

lysosomes and lipid droplets; markedly swollen and disrupted

mitochondria and

extreme dilatation of rough endoplasmic reticulum (RER).

Clin Immunol Immunopathol 1993 Nov;69(2):189-98

An excess of dietary iodine accelerates the development of a thyroid-

associated

lymphoid tissue in autoimmune prone BB rats.

Mooij P, de Wit HJ, Drexhage HA.

Department of Immunology, Erasmus University, Rotterdam, The

Netherlands.

Previous studies have shown that dietary iodine enhances the

severity and

incidence of focal thyroiditis in autoimmune BB rats and OS

chickens. However,

which lymphoid cells are involved in the development of the iodine-

induced focal

thyroiditis and what the consequences are for the anticolloid

antibody

production have not been studied in detail. We therefore performed a

study in

which 3-week-old female BB rats were kept on either an enriched

iodine diet

(EID; iodine intake, 100 micrograms iodine/day) or a normal iodine

diet (NID;

iodine intake, 7 micrograms iodine/day) for a period of 18 weeks. The

development of the focal thyroiditis was immunohistologically

studied.

Immunohistological data were compared to the thyroid hormone status

and

anti-colloid antibody production. Our data confirm that a high

dietary iodine

intake results in an accelerated development of the focal lymphoid

cell

infiltrates in the thyroid of the BB rat. After 12-18 weeks of an

EID 50% of the

BB rats developed these infiltrates. Our data additionally show

that: (a) the

process starts with increases in the number of infiltrating MHC class

II-positive dendritic cells and a clustering of these cells with T

cells, B

cells, and some macrophages and ( the focal infiltrates are highly

organized

and consist of central B cell follicle-like structures surrounded by

rims and

areas of T cells. The architecture of the focal thyroiditis is hence

very

similar to mucosa-associated lymphoid tissue and secondary lymphoid

organs

(spleen and lymph node). Only minor signs of thyrocyte destruction

were

observed. We therefore consider the term " thyroiditis " as

inappropriate and

prefer the term " thyroid-associated lymphoid tissue. " Since the

thyroiditis

component was small, it is also not surprising that the BB rats on

the EID

remained euthyroid. The presence of the thyroid-associated lymphoid

tissue in

the BB rats was positively correlated to the presence of anti-

colloid antibody

in the serum of the BB rats. We speculate that the dietary iodine

might have

direct effects on cells of the immune system or on cells forming the

microenvironment of lymphoid tissue (reticulum cells). A role for

highly

iodinated thyroglobulin in the accelerated development of thyroid-

associated

lymphoid tissue is also possible.

Endocrinology 1987 Aug;121(2):481-5

Iodine-induced thyroiditis and hypothyroidism in the

hemithyroidectomized BB/W

rat.

EM, Appel MC, Braverman LE.

We have recently reported that iodine administration (0.05% iodine

in drinkingwater) to weanling, diabetes mellitus- and lymphocytic

thyroiditis (LT)-prone

Biobreeding Worcester (BB/W) rats strikingly increases the incidence

of LT

without occurrence of iodine-induced hypothyroidism, which

frequently results

when excess iodine is administered to euthyroid patients with

Hashimoto's

thyroiditis. Since hypothyroidism did not occur in the iodine-

treated BB/W rats,

hemithyroidectomy was carried out in 30-day-old BB/W rats to

increase thyroid

mass and functional reserve. Iodine administration for 60 days

markedly

increased antithyroglobulin antibodies (0.40 +/- 0.08 vs. 0.15 +/-

0.06 OD; P

less than 0.02), the incidence of LT (68% vs. 13%; P less than

0.001), and

thyroid weight of the residual lobe (10.5 +/- 0.7 vs. 6.3 +/- 0.3

mg/100 g BW; P

less than 0.001) and induced hypothyroidism (T4, 2.5 +/- 0.2 vs. 3.0

micrograms/dL; P less than 0.05; T3, 25.1 +/- 1.9 vs. 37.5 ng/dL; P

less than

0.001; TSH, 252 +/- 49 vs. 61 +/- 14 microU/mL; P less than 0.02).

Hypothyroidism in the iodine-treated rats occurred primarily in

those with LT.

Similar studies were carried out in the non-diabetes mellitus-, non-

LT-prone,

genetically equivalent BB/W rats (W-line), the parent strain Wistar-

Furth rats,

and Sprague-Dawley rats. Iodine administration did not induce LT or

antithyroglobulin antibodies in these three strains and did not

affect thyroid

function in Wistar-Furth and Sprague-Dawley rats. However, in the W-

line rats,

iodine excess did induce thyroid enlargement in the residual lobe

(8.4 +/- 0.2

vs. 6.4 +/- 0.2 mg/100 g BW; P less than 0.001), a decrease in serum

T3 (71.5

+/- 2.9 vs. 86.0 +/- 2.5 ng/dL; P less than 0.001), and an increase

in serum TSH

(344 +/- 65 vs. 69 +/- 6.0 microU/mL; P less than 0.001). It is

evident,

therefore, that hemithyroidectomy in BB/W rats sufficiently reduces

functioning

thyroid tissue, resulting in iodine-induced LT and hypothyroidism,

similar to

iodine-induced hypothyroidism in euthyroid patients with Hashimoto's

thyroiditis. It is unclear, however, why iodine administration also

induced

hypothyroidism in hemithyroidectomized, genetically similar, W-line

rats in the

absence of LT. This observation suggests that iodine-induced

hypothyroidism in

rats may be genetically determined.

The key to the Wolffe Chaikoff study is that it was a temporary event and

after a period of time all things normalized with the increased iodine.

I've read numerous studies on both sides of the fence regarding iodine, in

particular

regarding Hashi's, as my daughter had a raging case of it. Her antibodies were

termed

" astronomically high " by her doctor. He had never seen TPO that high and I have

never

found anyone else whose numbers came close to hers. There are also links to

Hashi's

being caused by too little iodine, in particular when there's been exposure to

fluoride,

which is right up our alley.

I still don't see any references to Peat and anything he's written regarding the

iodine docs.

If there is any info written by Peat regarding that, I would be interested. It

makes me

question the articles also when they're referenced to being collected by Peat.

I don't mean

to be rude, but how can you substantiate that?

Thanks for pointing that out Linn. I too am looking for evidence presented

by Peat that this is an issue - not the articles that were posted here. We

were discussing Peat and I have yet to see his analysis.
