Why Japanese Men Have Low Heart Disease….

August 1, 2008

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.


  • 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!
