A recent study has now established that consumption of fish oil can counteract the effect of air pollution, known to have a disastrous effect on cardiac health. The results of the present study have valuable implications with the ever-increasing air pollution levels in our environment.
The study participants were required to consume a 2g fish oil supplement everyday for a period of 6 months. Those who consumed soy oil supplements formed the control group. At the end of the study, it was found that those who consumed soy oil had marginal, non-significant benefit while the heart rate was found to be stable in the experimental group.
It is hypothesized that the presence of omega-3 polyunsaturated fatty acids in fish oil could contribute to the observed therapeutic effect against arrhythmia and sudden cardiac death as a result of exposure to air pollution. The GISSI study has revealed that highly purified ethyl ester form of fish oil could reduce heart attack deaths by 45%.
Following the promising findings, the researchers advocate the consumption of fish oil for a substantial improvement in general health. This is especially important, as there is a decline in the quality of the fish consumed over the recent years as a result of water contamination with mercury and PCBs.
