This article at NaturalNews.com by John Phillip discusses new research published in Cancer Prevention Research about high fiber and prostate cancer. However when you look closer you’ll see that the ingredient involved was IP6. IP6 is found in high fiber diets.
In the study the mice that were on the IP6 diet had a reduction in tumor sizes. This would help explain the slower progression of prostate cancer in eastern cultures as their high fiber diet has greater concentration of IP6.
