Japanese are known to be workaholic. They ahve been known to work long hours. Many are also smokers BUT why do they have a lower risk of heart disease?
A recent study published in the Journal of American College of Cardiology, August 2008 may have the reasons why….
________________________________________________________________________________________
Methods: A population-based cross-sectional study in 281 Japanese (defined as born and living in Japan), 306 white (defined as white men born and living in the U.S.), and 281 Japanese-American men (defined as Japanese men born and living in the U.S.) ages 40 to 49 years was conducted to assess intima-media thickness (IMT) of the carotid artery, coronary artery calcification (CAC), and serum fatty acids.
Results:
- Japanese men had the lowest levels of atherosclerosis, whereas whites and Japanese Americans had similar levels.
- Japanese had 2-fold higher levels of marine-derived n-3 fatty acids than whites and
- Japanese Americans in the U.S. Japanese had significant and nonsignificant inverse associations of marine-derived n-3 fatty acids with IMT and CAC prevalence, respectively.
Conclusions: Very high levels of marine-derived n-3 fatty acids have antiatherogenic properties that are independent of traditional cardiovascular risk factors and may contribute to lower the burden of atherosclerosis in Japanese, a lower burden that is unlikely the result of genetic factors.

This study further proves why Fish is the healthiest meat to eat. This trully explains why Japanese have a low risk of heart disease because of their lifetime increased intake of fish esepcially salmona dn mackerel which are both rich in omega 3 fatty acids.
I caution those who are buying Omega 3 supplements though because the effects are not proven in terms of the omega 3’s protective effect on the heart with regard to supplements.
Instead to reap the benefits of Omega 3:
Eat FISH 2-3 x a week!
