One of the most popular summer drinks is iced tea.. It perfectly quenches thirst and refreshes in the heat.. However, this drink is not as harmless as it might seem at first glance..

Loyola University Medical Center urologist John Milner found that drinking iced tea can cause kidney stones.

Together with factors such as excessive sweating and dehydration in summer, iced tea significantly increases the risk of developing urolithiasis.. "

The urologist noted that men are 4 times more likely to form kidney stones than women. Those at increased risk include people over the age of 40, postmenopausal women with low estrogen levels, and those who have had their ovaries removed..

Stones form due to the high concentration of oxalate, a chemical found in tea. Hot tea also contains this substance, but it is usually not drunk in the heat in such quantities as iced tea..

“I advise you to drink water with lemon, which is rich in citrates, substances that prevent the formation of kidney stones,” the scientist adds..
