Controvertial: Tea traditionally has shown to be high in oxalate that can cause kidney stones. Green tea's oxalate content is much lower. But the medical evidence has been conflicting with some recent studies actually suggesting a reduction in the stone risk from even non-green teas! until the jury is out, stick to drinking water..No rx required and cheap! ...Read more

Can daily consumption of green tea (I mix it with black tea as well) increase chances of getting kidney stones? The tea is unsweetened.

Can daily consumption of green tea (I mix it with black tea as well) increase chances of getting kidney stones? The tea is unsweetened.

Probably not: There's a "pop" claim that tea and cola predispose to kidney stones, but little scientific reason. The overriding key to prevention is to keep the urine dilute (always pale, never dark) by drinking plenty of fluids -- the cheapest is tap water, and perhaps tea-drinkers are actually just drinking less of that. ...Read more

Yes: Overall, because it contains antioxidants, green tea is a great addition to your diet. However, hydration is an important factor in keeping your kidneys healthy. Anything containing caffeine (like tea) may dehydrate you a little bit, so you will need to compensate with adding water to diet as well. If you need to jazz it up, try adding lemon or cucumber slices to water! ...Read more
