問題詳情

Even a small reduction of salt in the diet can be a big help to the heart. A new study published in the New England Journal of Medicine used a computer model to predict how just three grams less a day would affect heart disease in the United States.The result: Thirteen percent fewer heart attacks. Eight percent fewer strokes. Four percent fewer deaths. Eleven percent fewer new cases of heart disease. And two hundred forty billion dollars in health care savings. Researchers found less salt intake could prevent one hundred thousand heart attacks and ninety-two thousand deaths every year.According to the U.S. government, the average American man eats, on average, ten grams of salt a day; however, 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 1970s, while blood pressures have also risen. Less salt can mean a lower blood pressure.New York City Mayor, Michael Bloomberg, is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference.
