Obesity and other ill-effects of Iodine deficiency

If you were asked to name some of the most important nutrients for you body, chances are that one of your suggestions would not be iodine.  In fact it rarely rates any mention at all when one is asked to name as many nutrients as they can.  And it never even rates a consideration when listing the nutrients most deficient in the American diet.  And why should it?  We use iodized salt, so we’re covered, right?  Unfortunately in almost every case the answer is no.  At least 8 and probably 9 out of ten individuals are deficient (some very deficient) in this critical nutrient.  Iodine deficiency is widespread and may play a role in breast and ovary cancers, thyroid disorders, fibromyalgia, arrhythmia, diabetes, fatigue, chronic infections and obesity…all very common problems in western society. 

David Brownstein, MD, in his practice has tested over 4,000 patients and his results have been quite consistent – over 95% of his patients were iodine deficient.  Guy Abraham, MD, agrees and considers the problem so widespread that he says we have an epidemic of iodine deficiency in this country.

During the last 3-4 decades, iodine levels have fallen by nearly 50%.  During this same time period there has been an increasing number of patients complaining of symptoms consistent with under-functioning thyroid (hypothyroid) and auto-immune thyroid disorders.   If you think hypothyroidism may not be too common, consider the symptoms:  fatigue, weakness, dry skin, cold intolerance, low body temperature, headaches, weight gain, depression, constipation, brittle nails elevated cholesterol and many others….typical symptoms in any practitioner’s daily office schedule.

Among the components necessary for a healthy functioning thyroid, iodine has to rank near the top.  Without it, thyroid function and metabolism will be impaired.  This will affect the burning of fat for energy and heat.  Perhaps it is not coincidental then, that the epidemic of obesity parallels the epidemic of iodine deficiency and especially is this true during the last 35 years.  It is also of interest to note that during this same period more toxic and competitive halogens, such as bromine, fluorine, chlorine and chlorine compounds, have significantly increased in our environment and have found their way into our food, water and medicinals.  These compounds competitively inhibit iodine absorption, promote an iodine deficiency and replace iodine stores in fat cells, where they block the release of fat and inhibit weight loss.  This effect on weight loss is considered by some to prevent weight loss beyond a certain point.  A plateau is reached in the weight loss endeavor and patients feel incapable of a further reduction in weight.

So why is iodized salt not enough for us?  Well, keep in mind many people avoid salt or reduce its consumption.  But even when freely used in the diet, there is over 30,000 times (on a molar basis) more chloride than iodine ions in iodized salt.  Remember the competitive problem I mentioned earlier?  (Think also of Splenda®– where chlorine is complexed to the sugar molecule)  Now it only takes a very small amount of iodine to prevent a goiter, .05mg/day, but we need much more than that to successfully operate a thyroid gland and complete all the other projects found in the iodine job description.  It is in fact, found in every organ and tissue of the body but especially in the thyroid, liver, lung, heart and adrenals.  Its highest concentration appears to be in fat and muscle tissues, however.  And yet the daily iodine intake levels set by the WHO (World Health Organization) were recommended with the goal of prevention of simple goiter and not for nourishing the whole body with the amount of iodine all the other tissues might need.  Consider that only 20 – 30% of total body iodine is found in the thyroid gland.

The conventional approach to treating hypothyroidism is the use of synthetic drugs.  However the long-term use of these synthetic drugs such as Synthroidtm, is associated with a depletion of tissue iodine levels.  It would only make sense then to recommend that iodine/iodide should always be used with these drugs. 

The work of Drs. Abraham and Brownstein has shown that iodine, the universal nutrient, has at least 5 major functions overall:

  1.  Weight Regulation, Hormonal Function and Energy
  2. Thyroid hormones must have adequate iodine to function properly.  These hormones that use iodine, simulate an increase in the number and size of the mitochondria – the cellular site for the production of energy.  This will directly affect the overall metabolic rate in the body.  But the thyroid hormone is also involved with the metabolism of fats and carbohydrates, heart rate and the strength of the heartbeat, muscle and gastrointestinal function, digestion, gene transcription and directly influences other endocrine hormones. In essence most every area of the body is affected by our thyroid function or lack thereof.

    Without sufficient iodine, thyroid hormones will dysfunction, which leads to a deficient metabolism and inadequate fat burning for energy and heat.  In addition it will be accompanied by a difficulty losing or maintaining previously lost weight.  No surprise to anyone with the ability to see, we have an epidemic of obesity in this country.  One of the reasons for this is that iodine is crucial for metabolism and weight loss.  Iodine and other toxic halogens will store in our fat cells and when the other halogens, like chlorine are excessive, they inhibit the function of iodine which facilitates the release of fat from the cell.  Do keep in mind, however, that iodine is no magic pill in your weight loss endeavor, if you are not following a correct eating and exercising program.

  3.  Immune Function
  4. Individuals with inadequate iodine levels are prone to infections of all types.  You remember putting iodine on an open wound?  Well, it naturally has anti-bacterial, anti-viral and even anti-parasitic properties.  In sufficient amounts it has been found to induce a destruction of cancer cells and iodine deficiency is associated with increased risk for cancers and cysts.  Finally, one of iodine’s least appreciated roles is its ability to act as a natural detoxifier of mercury, fluorides, chlorides and bromides.

  5. Fertility and Menstrual Function
  6. Probably due to its concentration and role in the thyroid, breasts and ovaries, iodine deficiency has long been associated with difficulty in conceiving.  But it is more commonly involved with menstrual irregularities, fibrocystic breasts, ovarian cysts and possibly early menopause and prostatitis in men.  Dr. Brownstein believes that iodine deficiency is a major cause of breast cancer and other diseases of the reproductive organs.

  7. Brain Development and Function
  8. Iodine and thyroid hormone deficiency will have a marked impact on intelligence and memory and is likely to play a significant role in learning disabilities and attention deficit disorders.  Iodine is also found in the eye and in the substantia nigra area of the brain – the area associated with Parkinson’s disease.  Even breast milk has (or is supposed to have) high amounts of iodine since this nutrient is very important for brain and nervous system development in children.

  9.  Heart and Arrhythmias
  10. Like underactive thyroid, heart arrhythmias are nearly epidemic.  Adequate iodine levels are necessary for a smooth regular heartbeat.  One of the more common drugs used to treat arrhythmia, Amiodarone, is primarily iodine in a sustained-release, but toxic form.  But caution here – it is not safe to use iodine along with Amiodarone – do consult with your physician first.

It was in the 1920s that iodine was first added to table salt.  As noted earlier, this practice gave a false sense of iodine sufficiency.  The medical community relied 100% on iodized salt instead of the previously used forms of iodine and iodide found in Lugol Solution (a 5% solution of 50mg iodine and 100mg potassium iodide per milliliter).  Rarely used since the 1950s, Lugol Solution provided twice the amount of iodine present in table salt (which also has none of the important potassium iodide form), and none of the competing chlorine ions.

So instead of adding or re-supplying the iodine, physicians relied on synthetic drugs (such as Synthroid) to treat patients with thyroid deficiency.  However there are many individuals who have 50 –80% or more of the symptoms of thyroid deficiency but have “normal” thyroid hormone levels, and none of these receive any treatment at all.  This is the classic Wilson’s Syndrome.  Those suffering with this syndrome always have low body temperature and have difficulty staying warm.  Which is why the late, Broda Barnes, MD, always found the basal body temperature (97.8 or lower suggestive of hypothyroid) a better indicator of thyroid function than that of blood thyroid levels. Yet there are a number of practitioners who feel they could substantially improve (if not cure) these Wilson’s Syndrome individuals as well as a very high percentage of those with classical hypothyroid or hyperthyroid conditions by normalizing iodine levels.

The thyroid gland, fat tissue, and some other vital organs appear to be repositories of toxic metals, such as mercury, along with other toxic contaminants. When this occurs, organ dysfunction is likely.  One of the benefits of iodine is that it facilitates increased removal and excretion of poisons from these tissues.  In addition it enhances the liver’s detoxification mechanisms.  Perhaps this is why Dr. Abraham discovered that even patients with a complete thyroidectomy benefited from iodine therapy.  He found that some of his patients who achieved iodine sufficiency were able to resolve diabetes without insulin and to normalize blood pressure with a reduction or elimination of their medication.

Testing for Iodine Sufficiency – home test

Here is a simple test to determine whether an iodine deficiency exists.  From a bottle of tincture of iodine (drug stores carry these), paint a 2 inch square area on your inner arm.  If it disappears in less than 8 hours, iodine need is indicated.

Testing for Iodine Sufficiency – lab test

A more definitive way of testing for iodine deficiency uses a pre and post urine evaluation.  Testing first involves collecting urine immediately upon arising for the spot or pre-test.  After this collection, 50 mg. of potassium iodide/iodine is ingested and then all urine passed in the next 24 hours is collected and measured, with a sample sent to the lab for analysis. In essence the more iodine found in the urine, the less the body needs.  Likewise, the less of the ingested iodine sample found in the urine, the more the body wanted the iodine and the greater the deficiency and need for supplementation.  If the body has sufficient iodine at least 90% will be excreted in the urine.  Supplementation is normally done rather gradually as iodine can mobilize toxic metals and other toxic poisons from storage sites in sufficient quantities to provoke symptoms.  Re-testing should be repeated no later than 3-4 months to ensure successful therapeutic results.

In regards to supplementation, keep in mind that nearly all available supplements found in health food stores or pharmacies contain only the iodide form of iodine.  However, Drs. Brownstein, Flechas, Abraham and others found that to successfully improve iodine levels in the body, it was necessary to include both the iodide (reduced) and iodine (oxidized) forms because the body needs both forms. The iodine content of food is extremely variable, but the richest food sources all come from the ocean – Kelp/seaweed, sea vegetables, sea bass, cod, haddock, and ocean perch.  Several of these may be a significant source of mercury as well.

It is highly unlikely for excess iodine intake to occur when following the recommended dosage schedule and following urine testing results.  But in very rare cases of excess, individuals may experience a metallic taste, increased salivation, sinus headache, nervousness, palpitations and a sense of fever, all easily rectified by adjusting the amount of iodine.  It should be noted, however, that some symptoms thought to be due to excess iodine, may in fact be the forced excretion of those toxic metals and compounds lodged in the tissues.

Summary       

When you put the whole picture together and compare our country with Japan, you have to ask, “What is the consequence of the Japanese ingesting many, many times the amount of iodine as the average American?”  And the answer is (at least in part), a much leaner population, a significantly lower rate of breast cancer, a lower infant mortality rate and a much better life expectancy.   Of course there are other factors but let us not forget, Iodine is a part of that improved health.

The need is to achieve whole body sufficiency of iodine.  When this state is reached it correlates well with overall well being.  Energy levels go up, sleep improves and less is required, elimination is better and skin complexion is much healthier.  The following results have been noted by one doctor:

* Goiters reduced/eliminated
* Elevated TSH readings lowered to normal
* Thyroid gland excretes toxins and other heavy metals
* Improvement of the liver’s detoxification mechanism
* Improvement in weight management
* Improved blood sugar and blood pressure regulation
* Improved menopausal symptoms
* Breast tissue normalization including fibrocystic breast disease
* Ovary tissue normalization of polycystic ovary syndrome
* Less brain fog and clearer thinking
* Heart function improvement with reduced arrhythmias
* Reduction of thyroid and breast cancer rates
