I drink about 1L/day I use to get kidney stones all the time. Told to stop drinking tea and dark sodas. After researching it for 10 minutes my Urologist didn't know what he was talking about. Contents of Oxalate: black tea 15 grams for 1 liter equals 15 * 5.11 = 76.65 milligrams of soluble oxalates Spinach has 645 milligrams of soluble oxalates per serving size! Cola sodas has 0 as in ZERO soluble oxalates per serving size. My doctor told me that was all new to him. I stopped going to him as a doctor. I ate spinach everyday. I stopped eat spinach I stopped having kidney stones.
