Recent studies have shown that regular intake of fish oils can reduce the chances of having a heart attack. Studies have ascertained that this occurs because of the presence of n-3 polyunsaturated fatty acids (PUFA), also known as Omega 3-fatty acids found in oily fish such as tuna and salmon.
According to studies taking 1 gm of n-3 polyunsaturated fatty acids daily considerably reduces (by approx. 42%) the risk of death and sudden death in people who had a heart attack. This beneficial effect of n-3 PUFA has been attributed to the reduced episodes of irregular heartbeats called arrhythmia.
Certain findings have shown that n-3 PUFA plays an essential role in regulating the electrical activity of the heart muscles cells thereby reducing the chances of arrhythmia. Researchers are very excited with this finding, as till date there is no effective therapy for arrhythmia. Hence, more and more studies are being conducted to establish the beneficial effect of these fatty acids on the overall health of the heart.
In fact, American Heart Association recommends eating two servings of fish twice a week, as it is a rich source of protein without the high saturated fat found in fatty meat products.
