Just when you thought you were making the right decision of selecting iced tea instead of soda, new studies show that iced tea raises the risk of kidney stones.
If you’ve suffered from kidney stones this summer it may be because you had too much iced tea.

Kidney stones, a disorder of the urinary tract, affect about 10 percent of the United States population. Men are four times more likely to develop these painful crystals than women, and the risk increases for those aged 40 and older, as well as for postmenopausal women with low estrogen or those with their ovaries removed.
