Fluoride exposure and indicators of thyroid functioning in the Canadian population: implications for community water fluoridation
Background There are concerns that altered thyroid functioning could be the result of ingesting too much fluoride. Community water fluoridation (CWF) is an important source of fluoride exposure. Our objectives were to examine the association between fluoride exposure...
Water fluoridation and hypothyroidism results of this study need much more cautious interpretation
The biggest problem with this paper, however, is in the interpretation which puts far too much weight on such weak evidence. The approach used is notoriously unreliable as a way of identifying independent associations and the lack of a clearly established prior...
Warren Critique of Peckham
The authors concluded that fluoride exposure should be considered as a contributing factor to hypothyroidism and that the study results raised concerns about the validity of community water fluoridation as a safe public health measure.
