Maybe you are newly diagnosed and want to know what part if any diet may play in your recovery. What do other people do? I have to stress that there are no absolutes here. As far as I know, no nutritional remedy for prostate cancer has ever been shown to be effective using the most stringest standards for scientific testing — random sample, double blind study, etc. But there is plenty of information that is provocative.
I am giving you a link to an article which discusses diet and PC. I chose it because it is very thorough, moderate, and is from the University of California, San Francisco (USCF), one of the highest-ranked cancer hospitals in the country (usnews.com). I don’t want to give you information from some fly-by-night institution. I am posting here a summary of the hospital’s recommendations.
The one item I think is worthwhile that I saw listed in the body of the article but I do not see mentioned here is the pomegranate. It is a powerful antioxidant and in one study, it extended PSA doubling time from 15 months to 54 months. So read more about it.

You mention flax seed as a beneficial source of healthy fatty acids. i think that it is worthwhile mentioning that there is an unresolved question regarding flax seed oil which, in some studies appears to accelerate the growth of prostate cancer cells.
