Even a small reduction in salt in the diet can be a big help to the heart. A new study used a puter model to predict how just three grams less a day would affect heart disease in the United States.
The result: 10% fewer heart attacks, 8% fewer strokes, 4% fewer deaths, 11% fewer new cases of heart disease, and 240 billion dollars in health care savings.
Researchers found it could prevent 100,000 heart attacks and 92,000 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California, San Francisco was the lead author. She says people would not even notice a difference in taste with three grams, or one half teaspoon, less salt per day. The team also included researchers at Stanford and Columbia University.
Each gram of salt contains four hundred milligrams of sodium（钠）, which is how foods may list their salt content.
The government says the average American man ears ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies, while blood pressures have also rise. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading effort called the National Salt Reduction Initiative. The idea is to put pressure on food panies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children’s Research Institute show that the calorie information on the menu can influence what parents order for their children.

解析：本文通过一项调查告诉我们食盐与很多疾病的关系，呼吁我们少摄入食盐。同时介绍了The National Salt Reduction Initiative以及Bloomberg等组织及个人在这方面做出的努力。
【小题1】A 细节图。根据文章第二段The result: 10% fewer heart attacks, 8% fewer strokes, 4% fewer deaths, 11% fewer new cases of heart disease, and 240 billion dollars in health care savings.可知BCD三种疾病都是和食盐摄入过多有关系的。只有A项没有提及。故A正确。
【小题2】C 推理题。根据文章第五段Each gram of salt contains four hundred milligrams of sodium（钠）, which is how foods may list their salt content.可知食物中食盐的含量是用sodium（钠）的量来衡量的。故C正确。
【小题3】D 细节题。根据文章倒数第二段New York City Mayor Michael Bloomberg is leading effort called the National Salt Reduction Initiative. The idea is to put pressure on food panies and restaurants. Critics call it government interference.可知the National Salt Reduction Initiative.的目的就是向食品公司或餐厅施加压力，让他们减少食盐的使用。故D正确。
【小题4】A 段落大意题。根据本段中心句第一句Mayor Bloomberg has already succeeded in other areas, like requiring fast food places in the city to list calorie information可知本段讲述的是Mayor Bloomberg在其他方面做做的努力。故A正确。
