This is the reason why children are stupid

The high level of stupidity in children has a good reason, besides lack of motor activity For the new generation, there are many meanings that have entered our food and settled in the minds of our children to raise the level of children’s stupidity twice or more. experts.

Since the XNUMXs, fluoride has been added to tap water in some industrialized countries to protect against tooth decay.

It was found that very high concentration levels of this substance cause great damage to the brain, while the concentration levels found in tap water are generally not dangerous.

"We realized that there were great doubts about the dangers of fluoride, especially for pregnant women and young children," Kristen Till of York University in Canada, lead author of the study published in the journal JAMA Pediatrics, told AFP.

Ways to increase intelligence

According to the researchers, fluoridated water is distributed to about 66% of the population in the United States, 38% of the population of Canada, and 3% of the population of Europe.

The study examined about 601 mother-and-child couples in six Canadian cities, 41% of whom live in areas supplied with fluoridated water from municipal authorities.

The researchers noted that each increase in the concentration of fluorine in the urine of pregnant women by one milligram per liter was associated with a 4,5-point decrease in IQ in boys between the ages of three and four years, but not in girls.

Taking into account the amount of fluorine that the mother ate daily rather than the amount in the urine, the researchers noted that each increase of one milligram was associated with a decrease of 3,7 points in the IQ of both boys and girls.

However, many experts in various fields ranging from statistics and toxicology to neuroscience, have criticized the study.

"I think the conclusions are scanty and limited," said Stuart Ritchie, a psychologist at King's College London. It may be important in a broader set of studies on this issue, but it alone cannot advance the debate about the dangers of fluorine.”

In anticipation of the controversy, Gamma Pediatrics issued, in an unusual step, a clarification statement, saying that publishing the study was not an "easy" decision.

Contributing to declining rates of tooth decay in the United States, adding fluorine to water is one of the XNUMX greatest public health successes of the XNUMXth century, according to the Centers for Disease Control and Prevention (CDC).
