I is for Iodine
Our bodies need minerals. Not just for strong bones but all sorts of metabolic functions. For some reason, nature decided to use many different minerals in our design. A lack of sufficiency of any mineral in our body means that the complex dance of bio-chemical activity and its manifesting higher-level function is thwarted in some way. We may or may not feel fine as an individual but a close up view of the body may reveal objective dysfunction.
The physical body is, at one level, a composite of atomic elements. Carbon, nitrogen, oxygen and hydrogen are the primary building blocks of all life as we know it. Mineral elements such as potassium, magnesium, sodium, calcium, phosphorous, sulfur, chloride are the major minerals used by all cells in the body. Still more minerals such as, boron, iron, zinc, copper, selenium, chromium, vanadium, molybdenum, manganese, cobalt, nickel, arsenic, & fluoride are frequently utilized as components of enzymes and are considered trace minerals as their total quantity in the body amounts to just 0.005% of the body’s total weight or less than 4 grams. Some people think that minuscule amounts of even lesser know minerals such as yttrium, indium, germanium, iridium are necessary for full functioning.
One necessary mineral that is surrounded by contradictory information and seems to be thoroughly misunderstood is iodine. It is looked askance by thyroid endocrinologists. It is feared by those that think they have experienced an iodine allergy. Doctors a century ago used tincture of iodine as virtually a universal medicine often with near miraculous results. The iodization of salt is considered a public health mandate in many areas of the world in an attempt to prevent cretinism – a mental and physical developmental disease. Most modern people probably never give iodine a second thought content with the vague notion that we probably get enough from food or generic multi-vitamin/mineral supplements.
For most people, iodine and the thyroid gland go together. The primary thyroid hormone thyroxine contains four iodine atoms in each molecule called T4. It is synthesized in the thyroid gland and secreted into the blood stream. A small amount of T3 or tri-iodothyronine is made and released, also. From a cellular point of view, short-lived T3 is the more metabolically active hormone being formed by the action of selenium-containing enzymes. T4 is also converted to T3 in the liver, kidneys, thyroid, pituitary, central nervous system, brown fat tissue and heart vessels. T3 is basic and fundamental to all cells and has a substantial effect on many processes in the body.
Diseases of the thyroid gland are broadly classed as hypo-thyroidism (low thyroxine output) and hyper-thyroidism (excessive thyroxine output). Typically, hypothyroidism is due to an auto-immune condition known as Hashimoto’s disease. Conventional treatment uses natural or synthetic thyroid hormone to make up the deficiency without dealing with the cause. Typically, hyperthyroidism is due to a condition known as Graves’ disease. Conventional treatments include the use of goitrogens that block the thyroid’s absorption of iodine or the use of radioactive iodine to destroy thyroid function followed by lifelong hormone therapy.
The body’s daily iodine needs to make thyroid hormone are not great. A lack of iodine can cause the thyroid to swell and appear as a deformity of the neck. This is called goiter and can be treated by consuming sufficient iodine. Interestingly, a small number of unconventional doctors have had a high rate of success treating both non-goiter hyper- and hypothyroidism with iodine and certain supporting nutrients.
A much greater need for iodine seems to be for breasts, stomach mucosa, salivary glands as well as the ovaries, thymus, nerves, joints, skin, blood vessels and bones. Iodine is also a unique antioxidant, suppresses auto-immunity yet strengthens a proper functioning immune system, can act as an anti-allergenic, allows managed cell death and help to maintain a bacteria-free stomach.
To accomplish iodine sufficiency, official authorities have established a Recommended Daily Allowance (RDA) of 100-150 micrograms (0.10 -0.15 mg). Nursing mothers are allocated 290 micrograms. The average intake is said to be 240 micrograms which is down to half of what it was a few decades before. That may take care of the thyroid if you are ‘average’. Other tissues need more.
One has to wonder why such low levels are considered adequate when there are numerous reasons that this bare minimum could easily be problematic. If you are born with even slight mental and physical impairment it could be that your mother’s uterus or breast milk could not supply the needs of your developing body. The Japanese on average consume over 10 mg. (not micrograms) per day via their cultural diet and avoid many problems related to a lack of iodine.
Of course, everybody has heard of iodized salt. This was mandated many decades ago due to the manifestations of cretinism around the Great Lakes area due to a severe lack of iodine in the soil during an era of largely local food consumption. Other areas of the world are known as goiter belts – Nepal, parts of western China, Java and the Southern Alps. Unfortunately, treating salt with iodine has had limited success due to a number of technical and cultural reasons.
In the US, iodine used to be added to bread as a dough conditioner. One slice of bread was a significant dose of iodine. Over the last few decades a chemical with similar properties, bromine, is now added to bread. Unfortunately, bromine has no known function in the body and displaces iodine in the body. From ubiquitous sources, chlorine and fluorine enter the body and further force out the meager reserve of iodine. This halogen competition in the body conspires to lower the body’s function due to both toxicity and sub-par iodine. The consumption of popular manufactured drinks that contain bromated vegetable oil merely exacerbates an already bad situation.
The environmental release of nuclear material happens during an atomic explosion or a nuclear power plant accident. Some of that material is in the form of iodine-131 which is radioactive. If that isotope finds its way into the body, it will more than likely end up in the thyroid gland. Because this isotope continues to emit tissue-destroying radiation, the thyroid will be adversely affected. A small consolidation is that the half life of this element is only 11 days but plenty of damage can occur in a few days time if the dose is sufficient. (Half life means that only one half is left after 11 days but the other half is still radioactive. Maybe ten times the half life would be considered a ‘safe’ timeframe – three months!)
What would protect you from environmental halogens and radiation is to have plenty of iodine in your tissues. This has been shown to keep these elements from finding residence in the body. The official procedure for protection against imminent exposure to radioactive fallout is to consume 130 mg of potassium iodide per day for up to 10 days. This is about 100 mg of actual iodine per dose.
This introduction to the physiological functions of iodine just touches on the most prominent issues. Dosing oneself with extra iodine can be beneficial or problematic depending on many factors. There is a cadre of current doctors in the US that have used various iodine protocols on thousands of patients to the benefit of health. It is very cost effective. Some people can’t even take a milligram of iodine without discomfort and skin outbreaks due to toxin displacement. Others take 100 mg or more per day with only benefit.
Please further consider that in our era of fractionated knowledge, statements can have an element of truth but imply a falsehood that is not acknowledged or clarified. For instance, enough Vitamin C to prevent scurvy is probably not enough for optimal functioning of the body. Enough iodine to prevent cretinism or goiter does not necessarily mean that it is sufficient. Other factors need to be in play also. The body needs full nutrition and a supportive environment to be healthy. What is necessary for health is not determined by a ridge codification of what is right and proper but rather an understanding of healthy physiologic function and all the elements that are involved. This is complicated and even the best current understanding is limited to a degree that even the so-called experts might be hard pressed to admit. Humans have always functioned with less than full knowledge and that should not limit our willingness to move forward guided by both a rational and intuitive mind.
