Overconsumption of iced tea may cause kidney stones
An urologist has warned that high consumption of iced tea, especially during the summer months, may contribute to the formation of kidney stones. According to assistant professor at the Department of Urology at Loyola University Chicago Stritch School of Medicine, iced tea contains high concentrations of oxalate, one of key chemicals that leads to the formation of kidney stones. Because many people choose to drink iced tea instead of water in the summertime, individuals who have a tendency to form the most common type of kidney stones are specifically at risk. Despite the fact that hot tea contains similar amounts of oxalate, it is difficult to consume sufficient amounts to cause kidney stones since 85% of tea consumed in the US is iced.
