Toothpaste and drinking water could be a reason behind your child’s low IQ.

A new report by the US National Toxicology Program has discovered the the fluoride amounts present in drinking water that exceed twice the limit recommended could be associated with low the IQ for children. This conclusion, based upon an analysis of published research, is the first time that a federal agency has discovered an association between fluoride intake and lower IQ among children.
Understanding Fluoride’s Role
The addition of fluoride is long-standing in drinking water to help protect teeth from cavities and strengthen them it is considered an important achievement in public health. Fluoride is also employed in toothpastes. Based on the US Centers for Disease Control and Prevention fluoride functions to replace minerals lost in regular wear and tear on the teeth. However, this latest report outlines the potential risks to neurological health that are associated with excessive levels of fluoride particularly for children.
Expert Opinions on the Report
Ashley Malin, a researcher at University of Florida. Ashley Malin, a researcher from the University of Florida who has investigated the impact of fluoride exposure on pregnant women and their infants she described the study as “crucial” in understanding the dangers. She said it’s the most rigorously-studied research in its field.
Global Research and Recommendations
The report analyzed studies from a range of countries that included Canada, China, India, Iran, Pakistan, and Mexico. The studies found consistently that drinking water containing fluoride levels that were higher than 1.5 milligrams/liter was linked to lower IQs among children. Although the study did not provide a precise measurement of the IQ reduction, a few studies suggest a drop of between 2 and 5 points among children who were exposed to fluoride levels that were higher.
In 2015 US Federal health authorities have recommended a minimum level for fluoridation of 0.7 milligrams per liter. This is less than the prior upper limit of 1.2. The WHO’s acceptable limit of fluoride levels in drinking water is 1.5 milligrams per Liter.
Public Health Concerns
About 1.9 million people living in The US have been exposed to drinking water that has naturally fluoride levels that are 1.5 milligrams per Liter or more. Malin said that the results have raised questions about the best way to safeguard these populations and what precautions are most beneficial.
The report didn’t draw any conclusions about the risk of having lower levels of fluoride, or the effects it has on people of all ages, suggesting that more research is required.
Historical Context and Future Considerations
Fluoride is a natural mineral that is found in soil and water and its importance in dental health was first recognized around 80 years ago. One of the first US city to introduce fluoride in tapwater came from Grand Rapids, Michigan, in 1945. Federal officials have pushed for fluoridation of water since 1950 to prevent treatment against tooth decay.
However, the worries about the effects of fluoride in brain growth have increased. Research has suggested that fluoride concentrations high may affect neurochemistry and the function of brain cells which are involved in learning and memory.
Rick Woychik, director of the National Toxicology Program, emphasized the importance of having the right science because of the significance of fluoride for public health. While debates continue some experts, such as Malin who suggested pregnant women consider cutting down on their intake of fluoride and that discussions about policy on the amount of fluoride present in beverages could be required.
