A new study looked at levels of omega-3 fats, such as those found in fish, and the buildup of plaque in the arteries of 868 middle-age Japanese men living in Japan, Japanese men living in the U.S. and white men living in the United States.
The research, published online in the Journal of the American College of Cardiology, found that omega-3 fat levels in blood of the Japanese men living in Japan were twice as high as the levels in both the Japanese men living in the U.S. and the white men living in the United States.
