Prostate Cancer is the second leading cause of cancer death in men, with 240,000 new cases expected this year just in the United States alone. But guess what, statistics show that Prostate Cancer is 30-50 times higher in western countries, which points to LIFESTYLE FACTORS as an important cause.
If you are diagnosed with Prostate Cancer, or the precursor, an enlarged prostate, what do doctors recommend? Sometimes its just “watchful waiting.” For serious or more aggressive forms, its surgery and radiation.
In 2005, Dr. Dean Ornish and a team of doctors studied the effects of a change in diet and lifestyle of a set of patients that had Prostate Cancer. The control group made little or no lifestyle changes, while the intervention group made significant lifestyle changes. The lifestyle changes that Ornish prescribed included an exclusively plant-based diet, fish oil and vitamin C and E supplements. Fruits, vegetables, whole grains and legumes were mostly consumed, along with soy products. In addition to plant-based diet, patients performed 1 hour of yoga or other stress management techniques daily, along with 30 minutes of walking 6 days a week.
In the “Intervention Group”, serum PSA decreased by 4% from the baseline average, while the control group serum PSA increased 8% over the baseline average. Also, the study showed that serum from the intervention group inhibited prostate tumor growth in vitro by 70 percent but only 9 percent in the control group.
The bottom line? A diet low in fat and high in plant-based nutrition may slow the progression of early prostate cancer. The Ornish study isn’t the only evidence of the positive effects of a plant based diet. Other studies found protective effects of cruciferous vegetables and tomato sauce, and the increased prostate cancer risk when consumption of meat, dairy and fat increased. So switch to a plant based diet and get out your walking shoes. If you don’t have Prostate Cancer now, consider your Plant Based Diet a great way to protect yourself from the traumatic and life-changing results of this disease.
