About this study
This is a randomized control trial testing the effect of walnut supplementation on prostate cancer progression in 50 men with biopsy confirmed prostate cancer and planning to undergo RP. Patients consented to the study will be randomly assigned to either continue their usual diets (control arm) or to the walnut arm for 4-10 weeks depending on the window between their consent date and the date for RP.
