A diet rich in omega-3 fats may explain why middle-aged men in Japan have fewer problems with clogged arteries than similar men in the United States.
The research found that Japanese men living in Japan had twice the blood levels of omega-3 fats, and also lower levels of atherosclerosis, compared to middle-aged white men or Japanese-American men living in the United States.
Atherosclerosis is the buildup of plaque inside your arteries. Over time, they can lead to serious problems like heart attacks and stroke.
Nutritional studies show that intake of omega-3 fats averages 1.3 grams per day in Japan, compared to 0.2 grams per day in the United States.
