Re: Iodine deficiency ! - falling intakes - goitregens - competition bromine and fluo

And something I had not checked before - does fluoride cross the placenta - yes - http://www.ncbi.nlm.nih.gov/pubmed/2182701 - which has scary potential implications.

The implications would be greater in those who are at risk of iodine deficiency and insufficiency in pregnancy.

Might it affect fetal brain development either directly or by inhibition of thyroid function and so iodine metabolism - Fluoride Alert saved me the trouble of looking for data - based on fetal autopsies high fluoride intake is associated with serious developmental abnormalities .

Some abstracts from the link below which is well worth a visit - truly an I want to scream moment - if mitochondria do not work everything is affected.

This data was of course related to high flouride intake, but as already discussed the uptake of flouride is altered by many factors including the form in which it is ingested, wider mineral uptake and availability, so the questions as to whether those who have intakes from water, food, drugs, excessive toothpaste, low mineral and iodine intake and other risks that may be additive are at higher risk of non optimal fetal development is as yet unanswered.

The human placenta does not prevent the passage of fluoride from a pregnant mother’s bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning.

As highlighted by the excerpts below, three Chinese studies have investigated fluoride’s effect on the fetal brain and each has found evidence of significant neurological damage, including neuronal degeneration and reduced levels of neurotransmitters such as norepinephrine. As noted by Yu (1996), “when norepinephrine levels drop the ability to maintain an appropriate state of activation in the central nervous system is weakened.” Studies of fluoride-treated animals have reported similar effects, including lower levels of norepinephrine. (Kaur 2009; Li 1994).

The following study involves the same fetal tissue that was examined in the Yu (1996) and Dong (1993) studies. Rather than investigating fluoride’s effect on the brain, however, this study examined fluoride’s effect on the ultrastructure of cells in several tissues in the body, including from the thyroid gland. As can be seen in the following description, the fetuses from the fluoride-exposed women were experiencing a systemic toxic effect.

Conclusions: Fluoride damage to cell structures was multifaceted. Cell membranes, mitochondria, rough endoplasmic reticulum, and nuclear membranes could all be damaged at the time of fluorosis.”


another study said

These changes indicate that fluoride can retard the growth and division of cells in the cerebral cortex. Fewer mitochondria, microtubules, and vesicles within the synapses could lead to fewer connections between neurons and abnormal synaptic function, influencing the intellectual development after birth. These questions await further research.
