"Revisiting the Science We Thought We Knew
For decades, no one studied fluoride’s effects on the developing brain. That silence began to break in the 1990s with a pioneering—if controversial—study by Phyllis Mullenix at the Forsyth Dental Center in Boston. Using laboratory rats, Mullenix found that high concentrations of fluoride accumulated in brain tissue and altered behavior in ways consistent with neurotoxicity. Her study, published in Neurotoxicology and Teratology in 1995, suggested that early-life exposure could impair learning and memory.
The dental establishment dismissed her work, and Mullenix soon lost her position. But in retrospect, her findings foreshadowed what would emerge from human studies decades later.
In the early 2000s, researchers began studying children living in areas of China, India, and Iran with naturally elevated fluoride levels in water. These were simple, cross-sectional studies, often with limited controls and small sample sizes. Still, they pointed in a consistent direction: children exposed to higher fluoride concentrations scored lower on tests of intelligence.
Then, in 2012, Dr. Anna Choi and colleagues at Harvard published a meta-analysis of 27 such studies. Their conclusion was sobering: children in high-fluoride areas had, on average, seven points lower IQ than those in low-fluoride areas. Most of the studies were imperfect—many lacked individual exposure data—but the consistency of results was striking. It should have been a red flag that fluoride, long assumed to be safe, might affect the developing brain.
Recognizing these hints, a new generation of scientists began applying the same rigorous, prospective methods that Herbert Needleman and others had used to uncovered the dangers of lead.
In 2017, Dr. Morteza Bashash and colleagues found that higher prenatal fluoride exposure, measured in maternal urine, was associated with lower IQ in their children—affecting both boys and girls. Importantly, the urinary fluoride concentrations in Mexican mothers were later shown to be comparable to those of women living in fluoridated communities in North America.
Two years later, in 2019, our team published data from the Maternal-Infant Research on Environmental Chemicals (MIREC) study in Canada. Importantly, our studied was conducted in communities with and without optimally-fluoridated drinking water. We found that each 1 mg/L increase in maternal urinary fluoride—a measure of exposure during pregnancy—was associated with a 4.5-point decrease in IQ in boys. The pattern held when we looked at municipal water data: children whose mothers drank water with higher fluoride concentrations scored significantly lower on IQ tests than those whose mothers consumed less-fluoridated water.
In 2025, Taranbir Singh and his team in Bangladesh reported similar findings in a large, well-controlled study: children exposed to prenatal fluoride levels—often lower than those found in many fluoridated communities—showed measurable reductions in IQ.
By now, the evidence had become impossible to ignore. More than 75 human studies have examined the relationship between early-life fluoride exposure and IQ scores. Most—though not all—found an inverse association.": https://x.com/FluorideAction/status/1983628961977712943 Also pls. see thread.
Ans: You've no idea..I had to do an "executive reboot" and my memory issues have been Himalayan....I in no-wise find such amusing I can assure you.... (Nb. esp. my calculus!!!!)
Meanwhile they studied the effects of iodine deficiencies lowering IQ significantly
That was 70 years ago, and the CIA has been doing nasty stuff in western ukraine ever since. One particular nasty thing the CIA did was they paid local food producers to NOT allow any iodine into the food supply of western Ukraine because the lack of iodine causes the worst form of retardation, it restricts the development of “intellect” and with that it makes the western ukrainians extremely vulnerable to propaganda and brain washing which the CIA took special efforts to make western ukrainians think all kinds of bizarre things like ukrainians dug the Black Sea and that Jesus was a ukrainian and that kind of stuff
When a human does NOT develop intellectually, and then is brain washed into hating all things Russian, there is very little that can be done to remedy that!
If I were the Russians, I would “filter” every a last ukrainian, and the diseased ones have to be put down of separated from polite society and sent to gulag. The current practice of enticing the rabid ones to the line of combat contact and liquidating them is comprehensively one of the best solutions to thin out the defective ones initially, but a complete filtering will be necessary eventually.
I'd rather treat them..that's kinda where I appear to be/am going with this...no joke at all especially when (for still the majority of my life) I was unaware of the cause of my condition (& therefore of its consequences) .. yet very aware (even as a teenager) of its effects/symptoms... ("I told you I was ill" etc.)
