Overconsumption of iced tea can lead to kidney stones

(Relaxnews) - When the summer heat hits, consider reaching for freshly squeezed lemonade or water rather than iced tea, which experts say can lead to the formation of painful kidney stones.

It's the quintessential summer drink and the thirstquencher of choice at backyard barbecues and outdoor patios, particularly in the US. But a urologist at Loyola University Medical Center in Chicago warns consumers that iced tea contains high concentrations of oxalate, one of the key chemicals that can lead to kidney stones.
