Hi .. I'm on the low oxalate diet and have been told to avoid foods high in oxalates as well as calcium and to avoid taking added calcium supplements. So even though cranberries are good for the urinary system, they are not good for us stone makers!
I'm sure others will jump in on the thread to help you ... maybe we can find a list of foods.
WELCOME .. you have found the right place to give, get and share advice with MSK!
