The Pawnee, Mandan and other Indian tribes (部落) along the Missouri built solid ring-shaped structhures of trunk, covered with earth and dried grass,housing adozen families.

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer 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 10,000 heart attacks and 9。200 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 Uni versity.
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 eats 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 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.
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 shows that the calorie information on the menu can influence what parents order for their children.
