Background. 1  Carbonated beverage consumption has been linked with diabetes, hypertension, and kidney stones, all risk factors for chronic kidney disease. Cola beverages, in particular, contain phosphoric acid and have been associated with urinary changes that promote kidney stones.
According to the NKUDIC, the most common form of kidney stone is calcium oxalate. Caffeine may act as an irritant for those who have kidney stones because of its diuretic effects and it may also contribute to their formation because of the oxalate in coffee. The NKUDIC suggests that you limit your coffee intake to one or two cups per day to limit its effects on kidney stones.
