Academic Community: New Research on Fluoride: Growing Evidence of Possible Health Risks

Ein Wissenschaftler mit Schutzbrille arbeitet im Labor mit verschiedenen Chemikalien und Laborgeräten als Sinnbild für wissenschaftliche Untersuchungen und Fachveröffentlichungen zu den Risiken von Fluorid.
  • Higher fluoride levels in drinking water are associated with an increased risk of fractures
  • The EFSA warns against excessive fluoride intake through food, water, and dental care
  • The FDA is removing swallowable fluoride supplements for children from the market
  • Studies show possible risks of high fluoride exposure during pregnancy and early childhood
  • New meta-analyses find associations between fluoride intake and lower IQ scores in children
Current Publications:

  • The meta-analysis shows: higher fluoride exposure is associated with lower IQ in children.
  • Children in early developmental stages are particularly vulnerable.
  • No safe threshold for harmless fluoride intake can be identified.
  • The authors emphasize: prevention must not come at the expense of child development.
  • Recommendation: reduce fluoride exposure during pregnancy and childhood.

  • EFSA confirms: children often ingest more fluoride than recommended.
  • The main sources are drinking water, toothpaste and fluoridated salt.
  • Excessive intake can lead to fluorosis of the teeth.
  • No additional health benefit from high amounts of fluoride.
  • Recommendation: critically review fluoride sources and reduce total intake.

  • New data show: fluoride passes through the placenta and reaches the unborn child.
  • High fluoride levels are suspected of impairing brain development.
  • No proven benefit of additional fluoride intake during pregnancy.
  • Infants can already ingest sufficient fluoride through drinking water and food.

  • Fluoride is suspected of increasing the risk of bone fractures.
  • The meta-analysis shows: higher fluoride levels do not mean increased bone density.
  • On the contrary – too much fluoride can weaken bones.
  • No demonstrable health benefit from high fluoride intake.
  • Experts are calling for a reassessment of fluoride exposure.
