     A small piece of fish each day may keep the heart doctor away. That's the finding of a study of

Dutch men in which deaths from heart disease were more than 50 percent lower among those who

consumed at least an ounce (盎司)of salt water fish per day compared to those who never ate fish.

      The Dutch research is one of three human studies that give strong scientific support to the long

held belief that eating fish can provide health benefits, particularly to the heart.

     Heart disease is the number-one killer in the United States, with more than 550,000 deaths

occurring from heart attacks each year. But previous research has shown the level of heart disease

is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths,

for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and

among the Japanese, whose daily fish consumption(消费量) averages more than 3 ounces.

     For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.

At the start of the study, average fish consumption was about two-thirds of an ounce each day, with

more eating lean fish than fatty fish.

     During the next two decades, 78 of the men died from heart disease. The fewest deaths were

among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos.

This relationship was true regardless of other factors such as age, high blood pressure, or blood

cholesterol(胆固醇) levels.
