Diet Soda and Kidneys

Tuesday, March 16, 2010

You might want to think twice before drinking that second or third diet soda of the day. You could be affecting your kidneys. Dr. Edward Hill takes a look at a study about diet soda and kidney performance in the 60 Second Housecall.

Dr. Hill:

Diet soda may help keep your calories in check, but drinking two or more a day may double your risk of declining kidney function.

Women who drank two or more diet sodas a day had a 30 percent drop in a measure of kidney function.

Researchers at Harvard Medical School evaluated 3,200 women participating in the Nurses Health Study.

When the researchers compared kidney function of the women in 1989 and 2000, they found that 11 percent had a kidney function decline of 30 percent or more. When they looked at the diet information, they found that the 30 percent decline in kidney function was associated with drinking two or more artificially sweetened sodas a day. This was true even after taking into account factors such as age, high blood pressure, diabetes and physical activity.

About 20 million Americans have some evidence of chronic kidney disease, according to the American Society of Nephrology. Kidney disease diagnoses have doubled each of the last two decades.
