A study led by researchers at the federal government’s National Toxicology Program (NTP) has found no link between elevated levels of fluoride and cognitive/learning deficits. The American Fluoridation Society (AFS) reports that the recently released NTP study examined rats that consumed food and water with varying exposures of fluoride. The researchers “observed no exposure-related differences in motor, sensory, or learning and memory performance” for any of the nine tests they conducted.
The Centers for Disease Control and Prevention (CDC) recognizes the benefits of adding fluoride to toothpaste and drinking water. The CDC and many leading health experts recommend adding fluoride to drinking water to help prevent tooth decay. Most public water systems in the U.S. add more fluoride to reach the level proven to reduce the rate of tooth decay for children and adults.
