That's the finding in a report posted in today's on-line issue of the European Heart Journal.
Researchers at Beth Israel Deaconess Medical Center say their test result simply adds to a growing amount of evidence showing Omega-3 fatty acids are good for cardiac health.
For the study, researchers followed more than 39-thousand Swedish men aged 45-to-79 over a six-year period.
Once the numbers were crunched, it turned out the men who'd eaten fatty fish once a week were 12-percent less likely to develop heart failure than those who ate no fatty fish.
There's even some encouraging news in the report for those who really don't care for the taste of bait.
Men who consumed about a third of a gram per day of cod liver or other fish oils were 33-percent less likely to develop heart problems than men who consume little or no marine related omega-3 fatty acids.
Fatty fish include herring, mackerel, salmon, whitefish and char.
