Fluoride’s ability to damage the brain is one of the most active areas of fluoride research today. Over 300 studies have found that fluoride is a neurotoxin (a chemical that can damage the brain). This research includes:
- Over 100 animal studies showing that prolonged exposure to varying levels of fluoride can damage the brain, particularly when coupled with an iodine deficiency, or aluminum excess;
- 50 human studies linking moderately high fluoride exposures with reduced intelligence;
- 45 animal studies reporting that mice or rats ingesting fluoride have an impaired capacity to learn and/or remember;
- 12 studies (7 human, 5 animal) linking fluoride with neurobehavioral deficits (e.g., impaired visual-spatial organization);
- 3 human studies linking fluoride exposure with impaired fetal brain development.
In November 2016, FAN, together with a coalition of environmental, medical and health groups served the Environmental Protection Agency (EPA) with a Petition calling on the Agency to ban the addition of fluoridation chemicals to public water supplies due to the risks these chemicals pose to the brain.
