I agreed with you that she has deficiencies (minerals like you mentioned and there are likely others) that are causing the cravings. I simply mentioned that parasites and bacteria are likely the cause of the deficiencies. In my experience it is better to "eliminate" the problem (pun intended) than to merely feed it. The more food and nutrients you ingest the more parasites you will be able to support (and the more toxins they will release into your body).
In what way have you found this not to be true Maggie?
