**Summary:**

1. **New Report**  
A U.S. government report reveals that fluoride levels in drinking water at twice the recommended limit (1.5 mg/L) are associated with lower IQs in children. This is the first federal acknowledgment of a potential neurological risk from high fluoride exposure.

2. **Study Findings**  
The report, from the National Toxicology Program, reviewed studies from various countries and found a consistent link between higher fluoride levels and reduced IQs in kids, with some studies indicating a drop of 2 to 5 IQ points.

3. **Current Recommendations**  
The U.S. has recommended a fluoride level of 0.7 mg/L since 2015, down from 1.2 mg/L previously. About 1.9 million Americans are on water systems with naturally high fluoride levels. More research is needed to understand the effects on adults and lower fluoride levels.
