In response to a mom who recently contacted me about adjusting her toddler's diet while waiting for testing and results to confirm CSID, I provided the below information via email. Then I realized other parents might find this helpful. So with a few revisions to apply to a general audience, here is my summarized list of foods to start with while trying to determine a CSID diagnosis or to use after confirmation as an Induction Diet modified from my original.
If you can get the books below as well, I am sure you will find them as helpful as I have. The authors do not mention CSID specifically, so some modifications are needed, but they have far more credibility than I do and Diane speaks on many things I did not feel qualified to mention in my book, though felt strongly about!
Her recipes are not exactly "kid-friendly" but between this book, Danielle Walker's Against All Grain books and cross-referencing the information I have regarding CSID, I think you will feel some control and direction.
As a disclaimer, I have no connection nor do I receive any compensation for these recommendations--they are simply books and food philosophies that have helped me to feed my family.
