I just want to add that my husband went through a period of juicing. He loved it, felt great. He lost some weight and the doctor was happy about that. Then she checked his blood (we moved and new doctors routine is full workup).
She called us at home, which is big, because that surgery doesn't ever do that. She told him to quit that immediately or he'd go into renal failure.
Please, please, please be careful if you decide to juice and please make sure you keep up with your doctor on your journey. Good luck however you choose to proceed.
