Eating salmon or other fatty fish once a week has been scientifically proven to be good for your heart and cuts down on risk of heart failure among men, bolstering evidence that omega-3 fatty acids do benefit the heart.
The researchers followed 39,367 Swedish men between the ages of 45 and 79 from 1998 to 2004. Researchers recorded details of their diet and tracked the outcome through Swedish inpatient hospital registers and cause-of-death registers.
During this period, 597 men in the study (with no previous history of heart disease or diabetes) developed heart failure. Thirty four men died.
Analysis of their numbers showed that the men who ate fatty fish (herring, mackerel, salmon, whitefish and char) once a week were 12 percent less likely to develop heart failure, compared with men who ate no fatty fish.
Although this association did not reach statistical significance, noted Levitan, the researchers also found a statistically significant association with the intake of marine omega-3 fatty acids, which are found in cod liver and other fish oils, said a BIDMC release.
The men who consumed approximately 0.36 grams a day were 33 percent less likely to develop heart failure than the men who consumed little or no marine omega-3 fatty acids.
These findings were reported in Wednesday's on-line issue of the European Heart Journal.
