AUA 2018: Can Coconut Water Consumption Potentially Prevent Kidney Stones?
Urinary analysis revealed that compared to tap water, coconut water consumption increased urinary citrate by 29%, urinary potassium by 130%, and urinary chloride by 37%, without significantly affecting urine volume or urine pH. An analysis performed of coconut water found that although it contains low levels of citrate, it contains high levels of total alkali (13.8 mEq/L). Despite relatively low citrate content (2.1 mmol/L), coconut water revealed a significant increase in urinary citrate excretion from baseline. This is likely due to the very high total alkali load, which their team believes is mainly a function of the high pH and malate content of coconut water.
Compared to other beverages associated with anti-lithogenic effects such as lemonade and dietary sodas, coconut water is lower in both sugar content and calories. Dr. Patel discussed his team’s future plans to further test the anti-lithogenic effects of coconut water in patients with hypocitraturia and a history of nephrolithiasis.
