Drinking
Diet Soda may reduce the risk of forming
Kidney Stones
Newswise — Patients with stone disease could benefit from
drinking diet soda. New research from the
University of California, San Francisco
suggests that the citrate and malate content
in commonly consumed sodas may be sufficient
to inhibit the development of calcium
stones.
The study was presented at the 104th Annual Scientific
Meeting of the American Urological
Association (AUA).
Increased alkalinity is proven to augment citraturia, a
known factor for calcium stones.
Malate increases the amount of alkali delivered.
Researchers measured the citrate and malate content of 15
popular diet sodas.
The researchers found that Diet Sunkist Orange contained
the greatest amount of total alkali and Diet
7-Up had the greatest amount of citrate as
alkali.
“This study by no means suggests that patients with
recurrent kidney stones should trade in
their water bottles for soda cans,” said
Anthony Y. Smith, MD, an AUA spokesman.
“However, this study suggests instead that patients with
stone disease who do not drink soda may
benefit from moderate consumption.”
