Reasons Why Your Iodine Levels Might Be Low

Water

If you are drinking water contaminated with high levels of fluoride, which many of us are, the fluoride competes with iodine in the body by mimicking Thyroid Stimulating Hormone (TSH). This is why fluoride is known as an endocrine disrupter.

Fluoride Overdose

A surprisingly small amount of fluoride can change thyroid function. This is something we have known since the 1800’s. Until recently, fluoride was used in Europe to treat hyperthyroidism and lower metabolic rate. Fluoride was even linked to goiter in the 1800’s, which should tell you something.

For a normal weight person, it has been reported that about 3.5 mg of fluoride ingestion per day can lead to thyroid dysfunction. No conspiracy theories here, these are facts on the U.S. Environmental Protection Agency website. Most people who ingest treated water take in about 5 to 8 mg of fluoride per day. Even more concerning is what fluoride ingestion does to our children.

Bromine Exposure

Bromine, like fluoride is an endocrine disrupter affecting thyroid hormone metabolism. We absorb bromine in baking goods, processed foods, plastics, soft drinks, pesticides, spas, and furniture (see my article on PEBs).

Soil Depletion

There is good evidence to show that intensive cropping, resulting in large scale removal of biomass from the soil, as well as widespread use of alkaline fertilizers, rapidly deplete the soil of its iodine content. Since both intensive cropping and use of alkaline fertilizers are widely practiced in almost all developing the countries, it is not surprising that nutritional iodine deficiency and endemic goiter are seen wherever they are looked for in these regions.

Iodine deficiency occurs when the soil is poor in iodine, causing a low concentration in food products and insufficient iodine intake in the population. With our huge mono crops, we are not letting our soils replete itself with the necessary minerals which affects our iodine levels.

Declining levels of iodine rich foods

As we over-consume our world’s supply of fish, shell fish, and other marine sources of food, iodine availability is decreased.  Sustainably raised sea foods might be a solution here.

Orthorexia

Eating a strict diet and not allowing for any flexibility. People lose sight of the forest through the trees by eating only one way. Examples of orthorexia include veganism, ketogenic, zero carb, etc. Find the best way of eating in relationship to where you live on this planet and you will be better for it. Many different cultures have found ways to get adequate minerals, read up on your anthropology.

Goitrogens

Certain vegetables like kale, cabbage, cauliflower and radish contain glucosinolates (thiogluosides) which are potential goitrogens. Eating too much of these foods (especially raw) inhibits the availability of iodine to the body from the food and thus leads to the development of goiter. Remember from the discussion above, that iodine is absorbed in such small amounts that it is easy for what little iodine there is in the diet to be bound and excreted causing a potential deficiency.
