Another meta-analysis of Chinese studies showing a possible relationship between fluoride exposure and lowered IQ has just been published. This study by Liu and Cian of the Department of Health Statistics, China Medical University, in Shenyang, China was published in Chinese (see the English abstract below).


The authors reviewed 13 individual studies and found that their statistical analysis suggested “a negative correlation between high fluorosis exposure and children’s intelligence development” and concluded that “Exposure to high levels of fluoride may adversely influence children’s intelligence development.”



FAN will be using some of the money we are raising right now to have this translated, along with the other 5 Chinese IQ studies which are still only available in Chinese.

This study by Liu ad Cian comes on the heels of the study by Tang et al. (2008) published in August and an analysis by Connett, M and Limeback, H, presented at the IADR conference in Toronto, in July. All three reviews have yielded similar conclusions.
