英语翻译
A small piece of fish each day may keep the heart doctor away.That’s the finding of an extensive study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day than those who never ate fish.
The Dutch research is one of three human studies that give strong scientific backing 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 researchers previously have noticed that the incidence (发生率) of heart disease is lower in countries 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 averages more than 3 ounces.
For 20 years,the Dutch study followed 852 middle-aged men,20 percent of an ounce each day with more men eating lean fish than fatty fish.
At the start of the study,the average fish consumption was about two-thirds of an ounce each day with more men 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.

每天一小块鱼,可远离心脏医生.这是一个研究广泛的荷兰男子的研究成果.其中那些每天消耗至少一盎司咸水鱼的人,比那些从不吃鱼的人,死于心脏病的人要低一倍多.
这个3人的荷兰研究小组,提供强有力的科学支持,以长期持有的信念认为,吃鱼可以提供健康的好处,特别是对心脏.
心脏病是头号杀手,在美国,每年有550000人因为心脏病发作而死亡.不过,研究人员先前已察觉到美国是心脏病发病（发生率）较低的国家,会消耗更多的鱼类.心脏病死亡有的,举例来说,其中爱斯基摩人的格陵兰,每天消耗约400克鱼,其中日本,其日常消耗量平均超过3盎司.
20年来,荷兰的研究之后852中年男性,百分之二以上男人每一天吃稀鱼类比脂肪丰富的鱼类多十盎司.
在研究开始时,平均消耗量的是大约有三分之二的每盎司每一天与更多男人吃稀鱼类比脂肪丰富的鱼类.
在未来二十年间,78的男性死于心脏病.最少的人死亡,其中该集团的人,经常吃鱼,即使是在水平远远低于那些日本人还是爱斯基摩人.这种关系是真实的,不论其他因素,如年龄,血压高,或血液中的胆固醇（胆固醇）的水平.
