Eat Fish to Prevent Advanced Prostate Cancer
For the first time, researchers have found something that can protect against advanced prostate cancer, and it's as simple as choosing the right things to eat.
Omega-3 fatty acids, especially the kind found in dark fish such as salmon, appear to significantly reduce the risk of advanced prostate cancer. This even proved to be true for men who carried the COX-2 gene, a known inflammatory gene.
Scientists gave food questionnaires to 466 men diagnosed with aggressive prostate cancer and 478 healthy men. They found men who consumed the highest amount of long chain omega-3 fatty acids had a 63 percent reduced risk of aggressive prostate cancer compared to men with the lowest amount of long chain omega-3 fatty acids.
When the researchers assessed the affect of omega-3s on men with COX-2, those who consumed the least amount of long chain omega-3 fatty acids were more than five times likely to have advanced prostate cancer. But men with a high intake of omega-3 fatty acids had a substantially reduced risk, even if they carried the COX-2 variant.
"The strongest effect was seen from eating dark fish such as salmon one or more times per week," study author John S. Witte, Ph.D., a professor of epidemiology and biostatistics at the University of California San Francisco was quoted as saying.
