Fluoride Toxic at Low Levels & Chat GPT Lying About Fluoride's Danger

The inclusion of research data from over 800 mother-child pairs in Odense, Denmark, when merged with data from comparable studies from Mexico and Canada, has led scientists to conclude that a level of just 0.45 milligrams of fluoride per liter (mg/l) of pregnant mother’s urine showed a statistically significant association between urine-fluoride and decreased child IQ. Generally, urine fluoride concentration is similar to the level of fluoride found in drinking water. The standard for fluoride added to drinking water supplies is 0.7 mg/l.
While the Odense cohort study did not find a statistically significant association between pregnant mother’s urine and child IQ at 7 years old, the authors discuss how the analysis could underestimate the fluoride association with the neurotoxicity outcome.
The Danish study did not find boys to be more vulnerable than girls, as had been found in the Canadian study.
The authors, writing in the European Journal of Public Health, report, “The combined data showed that an increase in maternal pregnancy urinary fluoride by 1 mg/l significantly predicted an IQ decrease by 2.06 points.”
They concluded that their findings have important public policy implications, writing, “Given the combined observations on more than 1500 mother–child pairs, the overall BMC [benchmark concentration] results likely reflect a threshold for adverse cognitive effects of prenatal fluoride exposure that occur at levels prevalent in many countries.”
“These findings support that fetal brain development is highly vulnerable to fluoride exposure,” they note.
The authors point out the limitation of the current internationally recommended maximum concentration, concluding, “The pooling of results from three prospective cohorts conducted in areas with wide ranges of overlapping exposure levels offers strong evidence of prenatal neurotoxicity, and these findings should inspire a revision of water-fluoride recommendations aimed at protecting pregnant women and young children. For example, the World Health Organization’s recommendation of 1.5 mg/l as an upper limit for fluoride in drinking water does not consider developmental neurotoxicity.”
Spittle Challenges Use of AI in Queries Regarding Fluoride Usage And Effects
In a recent editorial, Bruce Spittle, who is retiring as editor of the journal Fluoride, argues that the artificial intelligence program Chat Generative Pre-trained Transformer (ChatGPT) can’t be properly evaluated if its responses to questions on fluoride’s usage and side effects are compared to a “gold standard” that consists of the American Dental Association’s website.
Responding to a report from dental researchers at the Çanakkale Onsekiz Mart University in Turkey that appeared in the same issue of Fluoride, Spittle writes, “[Despite having] 175 billion parameters, ChatGPT had only limited knowledge of scientific developments that occurred after September 2021.”
He noted that when asked “Is water fluoridation safe?” ChatGPT said it was, and included in its response, “However, like any public health intervention, water fluoridation is not without controversy. Some people have raised concerns about the safety and ethics of water fluoridation. However, these concerns have largely been debunked by scientific research and expert panels.”
Spittle added, “There is very good quality evidence that the consumption of fluoride during pregnancy, at the levels used in community water fluoridation of approximately 0.7 mg/L, will result in an impairment in neurodevelopment resulting in a loss of IQ. An increase in fluoride of 1 mg/L in water and an increase of 1 mg/day of fluoride intake was associated with an IQ loss of 5.3 points and 3.66 points, respectively, for both boys and girls. This evidence indicates that the answer by ChatGPT to the question “Is water fluoridation safe?” should be:
“Water fluoridation is considered unsafe when fluoride levels are maintained within the recommended range. …”
…rather than:
“Water fluoridation is considered safe and effective when fluoride levels are maintained within the recommended range. ….”
As reported previously, Spittle’s editorials for the Fluoride journal are seen as the most relevant on the topic of fluoride as tabulated by the Web of Science database.

The Art of Liberty Foundation will be co-sponsoring a conference in Sedona, Arizona on November 3rd, 4th and 5th entitled: Liberty on the Rocks!
The conference brings together some of the leading lights in Liberty to discuss our current political situation and SOLUTIONS, including how to create local Liberty groups and Freedom Cells and how to move yourself out of organized crime’s crooked admiralty law system by correcting your status and standing. Friday night, there will be a VIP Dinner and concert Featuring Grant Prezence. Saturday we are at the Global Center for Christ Consciousness in Sedona for talks, workshops and a panel. There will be a Liberty expo with the ability to table. It is free for all on Saturday after 3:00 PM. Sunday we are taking folks for yoga and hiking in the most beautiful place on the planet.
