  Purpose

Men who are scheduled for radical prostatectomy are considered candidates for this study. Six weeks prior to surgery, the subject will undergo screening procedures to determine eligibility. If eligible, the subject will be randomized to one of two four-week nutrition programs - either a balanced Western Diet or a low-fat diet with fish oil capsules. The UCLA GCRC (General Clinical Research Center) chefs will prepare breakfast, lunch, and dinner, and meals will be delivered to subjects in coolers two days per week. Subjects will require a minimum of four visits to the UCLA GCRC.

Arms Assigned Interventions
Experimental: Western Diet
Subjects assigned to this arm will receive a western diet which will be prepared by UCLA's General Clinical Research Center and delivered 2 to 3 times per week.
 Dietary Supplement: Western Diet
Western diet (prepared by General Clinical Research Center) received 2 to 3 times per week for 4 weeks.
Other Name: Diet created by General Clinical Research Center.
Experimental: Low-fat diet
A low-fat diet with fish oil capsules will be assigned to patients which will be prepared by General Clinical Research Center and delivered 2 to 3 times per week. In addition, this group will be asked to take 5 fish oil capsules per day.
 Dietary Supplement: Low-fat diet
Low-fat diet with fish oil capsules (prepared by General Clinical Research Center) received 2 to 3 times per week for 4 weeks.
Other Name: Fish oil capsules: 1 g by Pharmavite Inc, Mission Hills, CA

Detailed Description:

Experiments have shown that a low fat diet high in fish oil may prevent the progression of prostate cancer. The purpose of this study is to determine if a low-fat diet combined with fish oil capsules will change the chemical substances present in blood and prostate tissue that are related to the growth of cancer cells. This study will compare how these substances are affected by either, a typical high-fat Western diet, or a low-fat diet combined with fish oil.
