In Uro Today there was an article regarding the association of diet (actually red meats) and PC. It was a meta analysis (ie: studying other studies). Their conclusion:
"In conclusion, the results of this meta-analysis are not supportive of an independent positive association between red or processed meat intake and prostate cancer."
Once again, I think we have to be very careful when extolling this or that diet/supplement as beneficial in eliminating, preventing, or reducing PC. Now, this study was just for red meat. But I have read a lot and I still fail to see definitive proof regarding what we ingest and PC. The best might be fish oil and vitamin D-3, but I think I've read some later studies even debunking some of that.
Having said that, we KNOW that there seems to be lots of evidence regarding diet and heart disease and overall health. So, surely, we should eat a low-fat diet and increase our intake of the good oils (eg: virgin olive oil) and reduce our intake of other stuff. One would even think that good overall health can only be beneficial in fighting PC.
But we should be careful about going overboard here in PC-specific food/supplement recommendations.
In a similar vein, we know exercise is VERY beneficial in so many ways. It would be interesting to see a study comparing those with similar PC characteristics with the only difference being exercise vs. non-exercise. Would there be a difference in terms of PC prognosis. I predict the exercisers will live longer and we know almost by definition they are in better condition. But in terms of the PC path, I am not convinced one group will do better than another.
We all like to believe that if we exercise and eat right, we are better in fighting PC. It makes sense, it sounds logical, but I'm not at all convinced that it is true.
