Water fluoridation also garnered national headlines when a bombshell report published by the Department of Health and Human Services last August revealed that excessive fluoride consumption in children has been linked to a two- to five-point IQ reduction. The startling admission prompted Edward Chen, an Obama-appointed federal judge, to order the U.S. Environmental Protection Agency to strengthen regulations around fluoride.

The U.S. widely began fluoridating its water supply decades ago as the result of a PR campaign led by Edward Bernays " author of the book Propaganda " who also convinced American women to take up smoking cigarettes.
