brain cancer and Dr. Budwigs Diet

My brother in law was diagnosed with brain cancer a month ago. We have just returned from M.D. Anderson, where they removed 95 t0 97% of the tumor. The cancer was at a stage 4 when diagnosed. He has agreed to try Dr. Budwigs diet. He loves to drink coke. Is diet coke out of the question!And where can I get a list of exactly what he can eat? Please hurry. Thank you,Gee
P.S. Is there anyone out there that has had brain cancer and used this diet? Tweet
