Fish and fish oils - protective, especially metastatic prostate cancer. Fish yes. Supplement not necessarily.

This study looked at the total amount of marine fatty acids that men consumed from fish and other sources.

 

Eating fish more than three times a week was associated with a reduced risk of prostate cancer. 

 

Moreover, it strongly reduced the risk of getting metastatic prostate cancer.

 

Getting the marine fatty acids from fish was more beneficial than getting the same amount from other foods.

 

Their findings findings suggest that the beneficial effect associated with eating fish may not necessarily be achieved by fish oil supplements.

Abstract

Experimental studies suggest that marine fatty acids have an antitumor effect on prostate tumor cells. The aim of this study was to investigate whether high consumption of fish and marine fatty acids reduces the risk of prostate cancer in humans. We followed 47882 men participating in the Health Professionals Follow-up Study. Dietary intake was assessed in 1986, 1990, and 1994, using a validated food frequency questionnaire. During 12 years of follow-up, 2482 cases of prostate cancer were diagnosed, of which 617 were diagnosed as advanced prostate cancer including 278 metastatic prostate cancers. Eating fish more than three times per week was associated with a reduced risk of prostate cancer, and the strongest association was for metastatic cancer (multivariate relative risk, 0.56; 95% confidence interval, 0.37-0.86, compared with infrequent consumption, i.e., less than twice per month). Intake of marine fatty acids from food showed a similar but weaker association. Each additional daily intake of 0.5 g of marine fatty acid from food was associated with a 24% decreased risk of metastatic cancer. We found that men with high consumption of fish had a lower risk of prostate cancer, especially for metastatic cancer. Marine fatty acids may account for part of the effect, but other factors in fish may also play a role.

(Allowed for PSA effect)

We found that a high intake of fish was associated with a lower risk of metastatic prostate cancer. A similar association was also found for dietary marine fatty acids from food. However, our findings suggest that the beneficial effect associated with eating fish may not necessarily be achieved by fish oil supplements.
