Deep dives
Adverse Effects of Fluoride Exposure
Recent studies raise concerns about the safety of community water fluoridation, particularly regarding its impact on cognitive development in children. Research conducted on pregnant women in Mexico showed a correlation between higher fluoride levels and developmental delays, with children exhibiting lower IQ scores by the age of four. A subsequent Canadian study involving over 500 mother-child pairs indicated that even optimally fluoridated water during pregnancy was linked to reduced child intelligence. These findings suggest that while fluoride may strengthen teeth, its potential neurological risks demand a reevaluation of current public health practices.
