Men with prostate cancer diagnosis may do better if they replace animal fat and carbohydrate with vegetable fat in their diet. It reduces their risk of developing lethal prostate cancer (progression into metastasis and prostate cancer specific death ) as well as all cause mortality. 4577 men with non-metastatic prostate cancer were studied prospectively between 1986 and 2010. There were 315 events of lethal prostate cancer and 1064 deaths with median follow up of 8.4 years. Replacing 10% energy intake from carbohydrate to vegetable diet caused lower risk of lethal prostate cancer (p=0.04) and all cause mortality (p=0.001). Saturated and trans fats after diagnosis were associated with higher incidence of all cause mortality (p=0.01). This report has been reported in JAMA Internal Medicine 2013; 173 (14):1318-1326. The examples of vegetable fats are olive oils, canola oils, nuts, seeds and avocados. Consumption of vegetable fat and oil increases antioxidants and reduces insulin and inflammations which may deter prostate cancer progression.
This study will play an important role in establishing association between diet and Prostate cancer and would encourage researcher to do further studies in this field.
