New information on fluoride intake and chronic kidney disease is available from the National Kidney Foundation and Kidney Health Australia.

National Kidney Foundation

On its newly revised Fluoride Web page, NKF notes, “The benefits of water and dental products containing fluoride is the prevention of tooth decay and dental cavities in people of all ages.”  In discussing potential health risks NKF states, “The risk is likely greatest in areas with naturally high water fluoride levels.”  Due to the limited available research on the topic, NKF has not issued specific recommendations regarding fluoride intake and kidney disease and currently has no official position on the optimal fluoridation of water.  NKF recommends that “Dietary advice for patients with CKD should primarily focus on established recommendations for sodium, potassium, calcium, phosphorus, energy/calorie, protein, fat, and carbohydrate intake. Fluoride intake is a secondary concern.”

Kidney Health Australia

In a position statement issued in March 2007, Kidney Health Australia concluded 1) there is no evidence that consumption of optimally fluoridated drinking water increases the risk of developing CKD, although only limited studies addressing this issue are available; and 2) there is no evidence that the consumption of optimally fluoridated drinking water poses any risks for people with CKD, although only limited studies addressing this issue are available.
