研究表明，过多盐的摄入，以及全谷物、水果和蔬菜的摄入量不足可能会缩短人们的寿命。研究的作者指出，不良饮食是全球死亡人数最多的原因，甚至超过了包括吸烟在内的任何其他风险因素。这项研究证实了健康专家一直以来对人们的告诫——均衡的饮食对健康长寿很重要。 Too much salt—and not enough whole grains, fruits and vegetables—may be shaving years off our lives, a new study suggests. In a study published Wednesday in the Lancet, researchers looked at people's eating habits across 195 countries to estimate how much poor diets contribute to mortality. What are their findings? One of them is that 11 million people die each year around the world because of certain foods or at least the lack of certain foods, according to the study. Lead author Ashkan Afshin, an epidemiologist at the University of Washington, said the researchers estimated that overall, poor diets are responsible for more deaths around the world than any other risk factor, including cigarette smoking, known to be one of the greatest threats to public health. The problem, he said, is not only what people are eating; but it's also what they're not eating. The study estimated that globally, 3 million deaths were caused by too much sodium—but another 3 million deaths were attributed to too little whole grains and another 2 million deaths to too little fruit. Experts say it confirms what health professionals have been teaching for years—a balanced diet is important for a long, healthy life. But is a poor diet really responsible for more deaths than even cigarette smoking? Nestle, a professor at New York University, suggested that it makes sense that dietary risks are higher because everyone eats—but not everyone smokes. So, she said that “diet is a risk factor for everybody.” Period Ⅰ　Welcome to the unit & Reading—Comprehending 授课提示：对应学生用书第1页 基础知识自测 Ⅰ. 看图写出单词 1. 　　2.　　3.　　 creamy dessert saucer 4.　　5. 　vinegar　　　　　　　 cycle Ⅱ.匹配英语释义 (　　)1.mood　　A．in a gentle way (　　)2.combination B. to change or be different according to the situation (　　)3.gently C．to produce or create sth.
