Long interested in practical neuroscience, John D. MacArthur researched and
wrote The Human Brain for Philadelphia's Franklin Institute Science Museum.

In 2013, I began focusing on neurodevelopment in
pregnancy, because the CDC said that preterm birth is the
"leading cause of long-term neurological disabilities in children":

Four years earlier, a New York State public-heath study found that:
"Domestic water fluoridation was independently associated
with an increased risk of PTB (preterm birth)."

Published Pregnancy Reports • Fluoride, Premature Birth and Impaired Neurodevelopment, Townsend Letter, November 2013. A global review of recent laboratory, clinical, and ecological evidence that fluoride is a significant risk factor for premature birth and long-term neurological disabilities in children. • Placental Fluorosis: Fluoride and Preeclampsia, Townsend Letter, May 2015. New research and diverse evidence implicate fluoride and fluorosis in the pathogenesis of preeclampsia, the dangerous pregnancy complication caused by the abnormal placenta. • Prenatal Fluoride and Autism, Townsend Letter, April 2016. Fluoride swallowed in amniotic fluid may disrupt colonization and composition of bacteria in the fetal GI tract – adversely affecting neurological and immunological development. Townsend Letter: The Examiner of Alternative Medicine is a respected journal published since 1983.

In 2016, the concise and well-documented book was published:
Pregnancy and Fluoride Do Not Mix

This website began in 2017.
It continues to be updated with new research.

I have long been concerned about the dangers of fluoridated water: • Did Somebody say Fluoridation?: Dispelling the Myth of Fluoridation (2001) • Water Fluoridation: Sales Pitch vs. Reality Check: Sierra Club (2008) • Comments and Charts: US Dept. of Health & Human Services (2011) • Don't Be Takin' Fluoride: Deconstructing the Fluoridation Sales Pitch (2012)
