Is Iced Tea Bad for a Person's Kidneys?

Although iced tea itself is not bad for a person's kidneys, a college medical center urologist has gone on record as stating that ice tea can contribute to the development of kidney stones. Loyola (Ill.) University Medical Center urologist and assistant professor Dr. John Milner went on record in 2012, stating that iced tea was one of the worst things someone with a tendency to develop kidney stones could drink.

According to the Mayo Clinic, kidney stones are small deposits of acid salt and minerals that sometimes develop inside people's kidneys. The passing of these stones is usually quite painful and sometimes requires medical attention, such as taking specific medications or, in a worst-case scenario, surgery.
