For years, we’ve been hearing about the unhealthy lifestyle that many Americans are living. Now, we have an idea of just how many people that describes, and it’s not good.
多年来，我们一直听到许多美国人不健康的生活方式。现在我们有一个想法，探究到底有多少人。情况并不太好。
Less than 3 percent of Americans are living the way they should, according to the medical journal Mayo Clinic Proceedings.
根据医学杂志梅奥临床学报，不到百分之3的美国人过着健康的生活方式。
In order to be considered healthy, the study said participants need to exercise 2.5 hours per week, eat a healthy diet, have a body fat percentage under 20 percent for men and 30 percent for women and avoid smoking.
研究表示，要达到健康标准，参与者每周要运动2.5小时，吃健康的饮食，男性低于百分之20女性低于百分之30的身体脂肪比例并且禁止吸烟。
But that proved to be a lot to ask. Less than 3 percent of people accomplished all four requirements regularly. Most people were able to get one or two, but 11 percent of participants did all four things they probably shouldn’t.
但还是有许多的问题。不到百分之3的人定期完成所有四项要求。大多数人都能达到一项或两项，但百分之11的参与者做了所有四件事。
Nearly three-quarters of Americans were able to avoid cigarettes, but most people failed to meet the other three parameters, especially body fat percentage. Fewer than one in 10 Americans had what’s considered a healthy amount of body fat.
近四分之三的美国人都能不抽烟，但是大多数人却不能满足其它三个参数，特别是身体脂肪百分比。在10个美国人中不到1人有被认为的健康身体脂肪含量。
And that can spell disaster, since each of those four factors can contribute to the number one cause of death in America: heart disease.
这会招致灾难，因为这四个因素中的每一个都会导致美国第一死亡原因：心脏病。
But even if it seems tough to accomplish everything on the list, researchers said adding even one healthy behavior to your routine can reduce your risk of cardiovascular disease.
要完成所有的事情似乎很难，但研究人员表示，日常增加一个健康的行为都可以减少你患心血管疾病的风险。
