in "Mystical Diets" by Jack Raso, there is a brief discussion of a study on the Gerson therapy, by Steve Austin (published in "Options: The Alternative Cancer Therapy Book" [1993]). Austin tracked the progress of 30 patients at the Gerson Clinic. Five years later he was able to locate or find info on 22 of the 30. Of the 22, only one was still alive - 21 were dead of cancer. The above numbers are not very encouraging, re: the efficacy of the Gerson treatment. Tom Billings
