is finding that, yes, it does appear that fluoridated water can contribute to hypothyroidism,

but let's outline the details so you have all the necessary information.

Allow me to put up here on the screen, the abstract, a systematic

as we'll cover here in a second, is a review of the available data. So it's very powerful data.

It's not just one study, but rather an analysis and summary of all the available literature.

So this is very powerful information, and this is arguably the highest level of scientific evidence.

At least it's the best available evidence to answer this question to date.

And let's quote the findings from this research group.

The present systematic review suggests a positive correlation between excess fluoride and hypothyroidism.

This calls the need for further well-controlled studies in this otherwise emerging alarming issue.
