FDA's Fluoride Toothpaste Warning
Fluoride toothpaste has a FDA-mandated warning:
"Children under 6 years of age: use a pea-sized amount"
When a child swallows 0.25 mg of fluoride, about 85% of the ingested fluoride is absorbed = 0.21 mg of fluoride. Exposure levels are measured in milligrams of fluoride per kilogram of weight, therefore a 5-year old 20 kg child's "intake level" of fluoride = 0.01 mg/kg.
The fetal fluoride "intake level" (0.056/3) = 0.019 mg/kg:
Worse: this overdose is daily for the months its developing brain is
They're told to do this, despite that last year a major study (Bashash et al. 2017) funded by the National Institutes of Health confirmed that higher levels of fluoride in pregnant women are associated with lower IQs in their children. The 12-year study was conducted largely by specialists in the field who did similar studies on other neurotoxicants.
In March 2018, the authors further concluded:
"Our findings add to our team's recently published report on prenatal fluoride and cognition at ages 4 and 6-12 years by suggesting that higher in utero exposure to fluoride has an adverse impact on offspring cognitive development that can be detected earlier, in the first three years of life.
In light of of this new evidence, telling pregnant women to consume
fluoride in water or in supplements is a human rights violation.
Worse, it is human experimentation.
*Although a best-case (least-dose) scenario that ingested fluoride is evenly distributed to mother and child, it is unknown. Also, animal research shows that fluoride concentrations can vary in different parts of the body. For example, in immature ducks it averaged 201 mg/kg in their skulls, 189 mg/kg in their brains, and 814 mg/kg in their pineal glands. (Table 1 for immature females and males.) "Compared with humans, the pineal gland of adult ducks had an almost 40 % lower concentration."
The brain's pineal gland is the central structure in the circadian system that governs most aspects of physiology and behavior in mammals, including sleep-wake cycles. The National Research Council said, "Fluoride is likely to cause decreased melatonin production and to have other effects on normal pineal function, which in turn could contribute to a variety of effects in humans."
It's estimated that children may ingest up to 40% of their toothpaste. Fluoride may accumulate in a child's pineal gland, as it's known to do in adults, especially since the pineal gland is outside the blood-brain barrier. The prevalence of circadian-rhythm sleep disorders tends to be much greater in young children with learning disabilities: "about 86% of children aged up to 6 years." Bruni and Novelli (2010)
