RFK Jr.’s Latest Health-Related Take Is So Bonkers Experts Everywhere Are Trying To Breathe

Steven Novella, M.D., a clinical neurologist at the Yale University School of Medicine, debunked the findings in a blog for Science-Based Medicine in 2023.

Novella’s criticisms are primarily twofold:

1. The studies relied upon are predominantly from communities in China, where the water is naturally fluoridated with much higher concentrations of fluoride than is found in U.S. water. While the CDC recommends 0.7 milligrams of fluoride per liter of water, some of the data was as high as 16 milligrams per liter.
2. Even the data with high levels of fluoride exposure isn’t all that compelling with respect to cognitive function. “The effect, in other words, if it is real, does not appear to be clinically dramatic,” said Novella.

“Of course, all potential neurotoxicity to the developing brain should be taken very seriously. Every IQ point is a precious human resource,” Novella wrote.
