Do Fruit Juices Contain High Levels of Fluoride?

The level of fluoride present in grape juice reported in the early 90’s was the result of carry over of an insecticidal agent used in organic¬†agriculture.¬† At the time the juice industry was seeking to shift production to organic systems and did not realize that these organic materials would leave residue of consequence.¬† The use of these organic materials was banned in the mid-90s and now quality specifications for grape juice allows that no more fluoride be present than is in municipal drinking water.

In the past, juice made from concentrate was also a problem, as fluoride is not destroyed during the concentration process. Juice companies used to buy concentrate and reconstitute the concentrate with the municipal fluoridated water, resulting in higher than desirable levels of fluoride. This process is no longer used.
