Switching to a vegan diet -- along with exercising, meditating and participating in support groups -- may halt, or even reverse, the progress of early stage prostate cancer, suggests a study published in the September issue of the http://www.jurology.com/">Journal of Urology.
The research is the first randomized, controlled trial showing that lifestyle changes may affect the progression of any type of cancer, say the authors.
The directors of the study were Dean Ornish, MD, clinical professor, and Peter Carroll, MD, chair of the Department of Urology, both of the University of California, San Francisco, and the late William Fair, MD, chief of urologic surgery and chair of urologic oncology, Memorial Sloan-Kettering Cancer Center.
The researchers studied 93 men who had elected not to undergo conventional treatment for their prostate cancer for reasons unrelated to this study. The participants were assigned randomly to two groups: those who were asked to make comprehensive changes in diet and lifestyle, and those who were not asked to do so.
Participants in the lifestyle-change group were placed on a vegan diet consisting primarily of fruits, vegetables, whole grains and legumes supplemented with soy, vitamins and minerals. They participated in moderate aerobic exercise, yoga or meditation, and a weekly support group session.
