too much of a good thing?

Perhaps you heard the recent news that the EPA has decided to lower the recommended levels of fluoride added to tap water.  What does it mean to you and your family?

The quick takeaway is that research is suggesting that the average levels of fluoride in our water should be reduced for optimal health.  Some health advocates, including Environmental Working Group (EWG), call for the elimination of added fluoride for infants and pregnant women (citing research by National Academy of Sciences, release found here and link to EWG’s blog here).  Fluoride has been added to drinking water for decades in an effort to reduce tooth decay.

What it means?

-         Tap water is still better than bottled water

-         Water filtered with a carbon filter (brita, etc) is better than unfiltered tap water (but a carbon filter cannot remove fluoride)

-         Water filtered with a full reverse osmosis (RO) system is purer than water filtered with a carbon filter.
