Cocoa, Chocolate and Kidney Stones
Question: Can cocoa and chocolate cause kidney stones?
Answer: Cocoa and chocolate are high in oxalates, naturally occurring compounds that can contribute to the formation of the most common type of kidney stone in susceptible individuals. Cocoa powders tend to contain a higher concentration of oxalates than chocolate bars, but a single, typical serving of either cocoa or chocolate can contain higher amounts of oxalates than people who are following a low-oxalate diet should consume in a day. For more details, see the Concerns and Cautions section of the Cocoa and Dark Chocolates Review.
