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 usually consumed sodas appears to 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. Scientists measured the citrate and malate content of 15 popular diet sodas. The scientists observed that Diet Sunkist Orange contained the greatest amount of total alkali and Diet 7-Up had the greatest amount of citrate as alkali.
