Drinking fluoridated water does not reduce IQ (intelligence quotient), as some scientists previously thought.

This was stated by a group of New Zealand researchers from the University of Otago.

Many popular theories talk about the devastating effects of fluoridated water, and some people are openly calling for a ban on fluoridation, citing its association with a number of serious diseases..

Fluoride is commonly added to water in the United States and some other countries as an additive to prevent tooth loss.. But many people don't trust this method because it's "

Some sprouts of conspiracy theories about fluoridated water date back to the end of World War II.. It was then believed that the Nazi regime secretly fluoridated the water in Germany to damage the pineal gland of people and keep them in submission..

Numerous conspiracy theories have raised a public dialogue about water fluoridation, its benefits and risks.. In 2012, researchers from Harvard University (USA) questioned the benefits of water fluoridation for human health..

They conducted a systematic review of scientific studies and concluded that children who live in regions with high levels of fluoride in the water have " Fluorine, the researchers said at the time, is "

However, these results have been challenged in a new study published by New Zealand scientists in the American Journal of Public Health..

Dunedin Multidisciplinary Study and Water Fluoridation The Dunedin Multidisciplinary Study is a large study of 1,000 people born in Dunedin, New Zealand, in 1972-1973. In this study, scientists from the University of Otago compared the IQs of participants who grew up in areas with and without fluoridated water.. They also tried to take into account the amount of fluoride people got in toothpaste..

The IQs of 992 study participants were assessed at ages 7-13. 942 of these participants were retested at age 38. Tests included word comprehension, reasoning ability, memory, and processing speed..

The team analyzed the results, looking for evidence of the impact of fluoridated water on the development of the intelligence of the inhabitants of Dunedin.. They took into account factors such as IQ variation during childhood, parental socioeconomic status, birth weight, duration of breastfeeding, education level, etc..

Study lead author Dr. Jonathan Broadbent describes the team's findings: " In other respects, we have confirmed that prolonged lactation contributes to high IQ.”.

Dr.

Broadbent suggests that the studies that found the link between water fluoridation and intelligence had flawed methodology and a high risk of error.. In an interview with Medical News Today, he said of the Harvard work: “The authors themselves indicated that the studies included in the review had differences, in some cases very serious ones.. Therefore, the meta-analysis turned out to be of poor quality.”.

Dr. Broadbent also said: " In reality, the opposite is true, because this water helps prevent tooth loss in many New Zealanders..
