Fluoridated Amniotic Fluid

Fluoride's antibacterial effects may disrupt bacterial colonization of
the fetal GI tract and affect neurological and immunological development.

Contaminating Our Most Precious Bodily Fluid

When a baby in the womb swallows fluoride in amniotic fluid (up to 15 ounces per day), it not only increases fluoride levels in the baby's bloodstream, but fluoride's antibacterial effects are a serious concern for the developing microbiome: by disrupting colonization and composition of bacteria in the fetal GI tract – adversely affecting neurological and immunological development.

In fact, a primary reason why pregnant women are encouraged to consume fluoridated water is to help "delay colonization of the infant oral cavity by cariogenic bacteria." – New Zealand's Chief Science Advisor (2014)

Fluoride Weakens Bacterial Adhesion Forces

In 2013, a key antimicrobial mechanism of fluoride was identified by researchers in experimental physics at Saarland University in Germany. Using artificial tooth surfaces (hydroxyapatite pellets), they tested fluoride's effect on the adhesion forces of cariogenic bacteria (Streptococcus mutans and Streptococcus oralis) and a non-pathogenic bacterium (Staphylococcus carnosus).

After they were exposed to fluoride, atomic force microscopy revealed that all three bacteria species exhibited lower adhesion forces. Because fluoride makes bacteria less able to stick to teeth, decay-causing microorganisms are more easily washed away by saliva or brushing. The researchers said, "Fluoride appears to weaken bacterial adhesion forces in general."*

This raises the question:

How do weakened bacterial adhesion forces affect the
developing microbiome, the gut microbiota in the GI tract
that plays an essential role in neurological
and immunological development?

"Half the truth is often a great lie." – Benjamin Franklin

New Zealand's Chief Science Advisor:
"The effect of maternal intake on fluoride concentration in the amniotic fluid and fetal blood does not vary between intakes of 0.25 and 1.0 mg/day." [Ref. #57]

This is a great lie, because the other half of the truth was omitted:
The fluoride concentration in amniotic fluid was significantly higher when maternal fluoride intake was 1.25 mg/day. [Ref. #57]

Right after recommending that pregnant women consume 3 mg of fluoride per day, the Chief Science Advisor fails to mention that women who consumed less than half that amount had significantly higher levels of fluoride in their amniotic fluid.

Brambilla, E., et al., Oral administration of fluoride in pregnant women, and the relation between concentration in maternal plasma and in amniotic fluid. Arch Oral Biol, 1994. 39(11): p. 991–994.

Abstract: The aim was to measure the ionic fluoride concentration in maternal plasma and in amniotic fluid after oral administration of different doses of sodium fluoride (NaF) to 121 pregnant women. They were divided into six groups, according to the dose administered; 0 for the control group and 0.25, 0.50, 0.75, 1.00 or 1.25 mg of F- for the others. The subjects were instructed to take the corresponding NaF dose both 24 and 3 h before amniocentesis. Amniotic fluid (5 ml) and venous blood (5 ml) were obtained from each subject. Ionic fluoride concentration was measured with an expanded-scale potentiometer and a selective fluoride electrode.

The results showed that F- concentration in amniotic fluid and, presumably, in fetal circulation, was not significantly different in groups taking 0.25, 0.50, 0.75 or 1.00 mg/day of F-. The F- concentration in amniotic fluid of the 1.25 mg/day group was, however, significantly higher than in all the other groups.
