  • Potential Co-exposure to Arsenic and Fluoride and Biomonitoring Equivalents for Mexican Children.

    Excerpts: Fluoride toothpaste use has been one of the most common strategies to prevent dental caries in Mexico and worldwide. Studies have reported that between 49.8% to 90.9% of children 6 to 13 years old use fluoride toothpaste at least once a day [45]. Toothpaste fluoride concentrations for children in Mexico varied from nondetectable to […]

  • Introduction to the 64 IQ Studies

    Overview As of November 2019, a total of 71 studies have investigated the relationship between fluoride and human intelligence, and over 60 studies have investigated the relationship fluoride and learning/memory in animals. Of these investigations, 64 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies […]

  • Fluoridation and cancer: The biology and epidemiology of bone and oral cancer related to fluoridation

  • Characterization of nervous system intoxication in occupational fluorosis

    Fluorine is a poison with a broad spectrum of action affecting the metabolic processes, tissue respiration, and neuroendocrine regulation. For this reason, even before affecting the bones, occupational fluorosis manifests itself clinically as a generalized disease with syndromes affecting a number of important systems and organs, including the nervous system. The neurotoxic effect of fluorine […]

  • Diabetes

    Diabetes mellitus is a potentially life-threatening disease, in which the body fails to properly regulate blood sugar levels. Diabetes mellitus affects nearly 26 million people in the U.S. alone—with 7 million of these remaining undiagnosed, and therefore untreated. Fluoride has been shown to increase blood glucose levels and impair glucose tolerance, likely by inhibiting insulin […]

  • John Kelly’s Letters

    The FDA’s derogation of duty in failing to appropriately regulate fluoride products came to light largely due to a nine-year investigation by the late New Jersey Assemblyman, John Kelly. Kelly became interested in fluoride after a study from the New Jersey Department of Health found higher rates of osteosarcoma (bone cancer) in adolescent males drinking fluoridated water. Prior […]

  • Little Hocking Water customers needed for C8 study

    An independent four-year study on the effects of C8 on Little Hocking Water Association Service District customers is set to begin this month. About 400 people will be asked in the following weeks to participate in the study by answering surveys and providing samples of blood and/or breast milk. Mailings are going out as early […]

  • Studies of relationships between the polymorphism of COMT gene and plasma proteomic profiling and children’s intelligence in high fluoride areas

    Fluoride (F) widely exists in environment with a significant increase in body burden accumulation in recent years. Internal exposure to F due to diet including food, water, fluoride-containing dental products like toothpaste and fluoride supplements, is extensively researched. Additionally, industrial pollution and coal burning have also been reported to be major sources of internal F […]
