　　U. S. Eats Too Much Salt

　　People in the United States consume more than twice the recommended amount1 of salt, raising their risk for high blood pressure, heart attacks and strokes, government health experts said on Thursday.

　　They found nearly 70 percent of U. S. adults are in high-risk groups that would benefit from a lower-salt diet of no more than 1,500 mg per day2，yet most consume 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 and rich in potassium and calcium 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 40一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.

　　詞匯：

　　譯文：美國人吃鹽過量

　　美國人的食鹽量比推薦食用量的兩倍還多，這增加了他們罹患高血壓、心臟病以及中風(fēng)的危險(xiǎn)， 政府部門的健康老師周二表示。 ?

　　健康老師發(fā)現(xiàn)近七成的美國成年人屬于高危人群，如果他們的日食鹽量降至1，500毫克，則會(huì) 從中受益,然而大多數(shù)美國成年人的日食鹽量接近3,500毫克。

　　“少吃鹽對(duì)人們很重要。采用低鈉并富含鉀、鈣的飲食方式有助于維持心臟健康、改善血壓”， 疾病預(yù)防控制中心的達(dá)爾文?拉巴德博士在一份聲明中談到。

　　“人們需要了解推薦日食鈉量的限制并?取措施減少鈉的攝入量”，拉巴德說。 疾病預(yù)防控制中心每周公布的有關(guān)死亡和疾病的研究報(bào)告采用了全國普查的數(shù)據(jù)，結(jié)果顯示三 分之二的成年人的日食鈉量均不應(yīng)超過1，500毫克，因?yàn)樗麄兪潜灰暈楦呶Ｈ巳旱暮谌嘶蛘吣挲g超 過40歲的人。

　　然而根據(jù)疾病預(yù)防控制中心2005―2006年的估計(jì),美國大多數(shù)人的日食鈉量為3,436毫克。

　　大多數(shù)食用鈉都來自于袋裝的、加工過的和餐廳食品。疾病預(yù)防控制中心稱其將和美國衛(wèi)生與 公共服務(wù)部的其他部門一道聯(lián)手主要食品生產(chǎn)商和連鎖餐廳,降低食品供應(yīng)中的鈉含量。

　　全國已有1，600萬人罹患心臟病，估計(jì)還有580萬人已患中風(fēng)。減少食鹽量可以使患這些疾病 的風(fēng)險(xiǎn)降低，疾病預(yù)防控制中心稱。
