In the first major scientific study of the macrobiotic approach to cancer, researchers at Tulane University reported that the 1-year survival rate among patients with pancreatic cancer was significantly higher among those who modified their diet than among those who did not (17 months versus 6 months). The one-year survival rate was 54.2 percent in the macrobiotic patients versus 10.0 percent in the controls. All comparisons were statistically significant.
For patients with metastatic prostate cancer, a case control study demonstrated that those who ate macrobiotically lived longer (177 months compared to 91 months) and enjoyed an improved quality of life. The researchers concluded that the macrobiotic approach may be an effective adjunctive treatment to conventional treatment or in primary management of cancers with a nutritional association. “This exploratory analysis suggests that a strict macrobiotic diet is more likely to be effective in the long-term management of cancer than are diets that provide a variety of other foods,” the study concluded.
