The Fluoride Deception by Bill Bryson

An investigative account that challenges the rationale for water fluoridation, tracing its origins and promotion through 20th-century science and policy while alleging industry and government collusion to minimize or suppress evidence of harm; the book examines historical research, secretive experiments, and regulatory decisions to argue that fluoride’s health risks—ranging from dental and skeletal fluorosis to potential neurological and endocrine effects—were downplayed as a matter of convenience and profit, and calls for renewed scrutiny of the practice and the science behind it.
