Wait what why would unsweetened black iced tea be bad for kidney stones??
Unfortunately black tea is high in oxalate, which in excess amounts can cause calcium-oxalate stones (the most common type of kidney stones). It's recommended that kidney stoners keep their daily oxalate intake below 50mg, and a cup of black tea can have up to 15mg.
Oh man, that's a dilemma. I've had a kidney stone, so I know that they are agony. But I'm English! I can't just not drink tea!
Do you add milk to your tea? When oxalate is consumed with calcium, it binds in the bowel and the calcium-oxalate is passed through the stool. When you consume oxalate without calcium, your body leeches calcium from your bones and it binds in the kidney, creating stones. So just try to have a bit of calcium-rich food with your tea. ๐
The only foods that should be avoided 100% are spinach, almonds, and rhubarb. The oxalate content in those foods is insane. Like five almonds has 110mg oxalate! That's why a lot of people who go on diets get kidney stones. They think they're being healthy by eating big handfuls of spinach and almonds, and then wind up in the hospital.
Yep I take milk, no sugar, thanks. If you're pitting the kettle on, like.
Thanks, didn't know most of this! Sad about spinach, and i guess i will have to limit the amount of my mum's homemade rhubarb ice cream that I eat, although I guess the cream would help?
