e closer to 3,500 mg per day. "It's important for people to eat less salt. People who adopt a heart-healthy eating pattern that includes a diet low in sodium(钠) and rich in potassium(钾) and calcium(钙) can improve their blood pressure," Dr. Darwin Labarthe of the Centers for Disease Control and Prevention said in a statement. "People need to know their recommended daily sodium limit and take action to reduce sodium intake." Labarthe said. The study in CDC's weekly report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are black or over the age of 40 — which are considered high-risk groups. Yet studies show most people in the United States eat 3,436 mg of sodium per day, according to a 2005 —2006 CDC estimate. Most of the sodium eaten comes from packaged, processed and restaurant foods. The CDC said it will join other agencies in the Health and Human Services department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply. Nationwide, 16 million men and women have heart disease and 5.8 million are estimated to have had a stroke. Cutting salt consumption can reduce these risks, the CDC said.

Together the two boys，who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak and hear Orlando lost his hearing at the age of one. German was born deaf, and his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kindergarten. “We were in a special class with about 25 other deaf kids.” German remembers. “Before then, I didn’t know I was deaf and that l was different.” “Being young and deaf in regular classes was very hard,” signs Orlando. “The other kids didn’t understand US and we didn’t understand them. But we’ve all grown up together, and today, I’m popular because I’m deaf. Kids try hard to communicate with me.” Some things are very difficult for the two boys. “We can’t talk on the phone, so if we need help, we can’t call an emergency service,” German signs. “And we can’t order food in a drive-thru.” Despite their difficulties, the two boys have found work putting food in bags at a local supermarket.
