Fluoride and the Thyroid gland

Fluoride and the Thyroid Gland
Research reported on in a variety of medical journals has indicated that excess of fluoride in drinking water is a risk factor for more rapid development of thyroid problems. Other research has also found that high Iodine and high fluorine exert severe damage to thyroid function, and potentially affect IQ. Workers exposed to fluorine are also at increased risk of thyroid problems.

Fluorine, being a halogen, and chemically related to Iodine but very much more active, displaces iodine, so the uptake of Iodine is compromised by the replacement of the iodine by fluorine. To condemn an entire population, already having marginal levels of iodine, to inevitable progressive failure of their thyroid system by fluoridating the water, borders on criminal lunacy. Out of the over 150 symptoms and associations of hypothyroidism, almost all are also symptoms of fluoride poisoning.


Fluorides are cumulative and build-up steadily with ingestion of fluoride from all sources, which include not just water but the air we breathe and the food we eat. The use of fluoride toothpaste in dental hygiene and the coating of teeth are further sources of substantial levels of fluoride intake. The body can only eliminate half of the total intake, which means that the older you are the more fluoride will have accumulated in your body. Inevitably this means the ageing population is particularly targeted. And even worse for the very young there is a major element of risk in baby formula made with fluoridated water and the extreme sensitivity of the very young to fluoride toxicity makes this unacceptable.


In concentrations as low as 1ppm, fluorides damage the thyroid system on 4 levels.


1. The enzyme manufacture of thyroid hormones within the thyroid gland itself. The process by which iodine is attached to the amino acid tyrosine and converted to the two significant thyroid hormones, thyroxine (T4) and triiodothyronine (T3), is slowed.


2. The stimulation of certain of the G proteins whose function is to govern uptake of substances into each of the cells of the body, from the toxic effect of fluoride, has the effect of switching off the uptake into the cell of the active thyroid hormone.


3. The thyroid control mechanism is compromised. The thyroid stimulating hormone output from the pituitary gland is inhibited by fluoride, thus reducing thyroid output of thyroid hormones.


4. Fluoride competes for the receptor sites on the thyroid gland which respond to the thyroid stimulating hormone; so that less of this hormone reaches the thyroid gland and so less thyroid hormone is manufactured.


These damaging effects, all of which occur with small concentrations of fluoride, have obvious and easily identifiable effects on thyroid status. The running down of thyroid hormone means a slow slide into hypothyroidism. Already the incidence of hypothyroidism is increasing as a result of other environmental toxins and pollution together with wide spread nutritional deficiencies.


The distortion of protein structure by fluoride causes the immune proteins to fail to recognize body proteins, and so instigate an attack on them, which is Autoimmune Disease. Autoimmune diseases constitute a body of disease processes troubling many thousands of people: R/A, SLE, Asthma, Systemic Sclerosis are examples. Thyroid antibodies will be produced which will cause thyroiditis resulting in the common hypothyroid disease, Hashimoto's Disease and the hyperthyroidism of Graves' Disease.
