The x-ray technician confirmed that she is completely cleaned out. She has only had sweet potatoes and spring water so far. BUT if she had a couple of hydrotherapy sessions in a couple of weeks she might find that things from her test yesterday would be spilling out. At any rate she can go ahead with the elimination diet. Rutabaga is different from turnip.
Yams are different than sweet potato.
ALL of them can be used during the elimination diet. I would advise Linda to not just eat sweet potato and spring water. The fish is optional at each meal but she should experiment seeing if it yields her more energy. Look at this as an experiment rather than a punishment. Well she is feeling pretty horrible right now.
