According to a recent study that is slated to be published in the Journal of the American College of Cardiology, eating more tuna, salmon and sardines keeps away heart ailments.
It states that the Omega 3, which is found in oily fish, gives the extra protection for the heart.
The study, which was conducted at two universities and a research institute in the U S and Japan, compared the White Americans, Japanese and Japanese Americans. It was found that the Japanese had the lowest levels of atherosclerosis and had higher levels of omega-3 fatty. Every aspect like blood pressure, serum cholesterol, body mass, smoking diabetes and body mass index was taken into account while making the study.
The study has shown that the higher levels of Omega 3 fatty acids prevent the extra accumulation of cholesterol in the arteries. The omega 3 fatty acids, which are a type of polyunsaturated fat, are found in abundance in fish. The most potent Omega 3 fatty acids - Docosahexaenoic acid and Eicosapentaenoic acid are found more in oily fishes like salmon, tuna mackerel.
