| One in four Chinese primary school students say they are too busy to eat fruit every day, while many dislike fruit for the simple reason that their 1 tell them to eat it. That is the result of a recent survey 2 the Chinese Association for Student Nutrition & Health Promotion(中国学生营养和健康促进协会), who last month issued a questionnaire among 1,500 children in Beijing, Shanghai and Guangzhou. They 3 28 percent didn't eat fruit every day and of those who did, one in seven did not eat enough. Among students who didn't eat fruit every day, 50 percent said it was because they "didn't have time" and 40 percent of those who didn't like fruit said it was because "my parents 4 me to". "Fruit is a natural source of many nutritional elements(营养元素), can balance a person's nutritional intake and help to 5 overweight(超重)," says Association director Du Yuxia. He says about 20 percent of primary school students in Beijing and Guangzhou are overweight, while the figure is 6 30 percent in Shanghai. Hu Xiaoqi, a nutrition expert with the Chinese Center for Disease Control and Prevention (CDC), believes a student should eat at least 150 grams of fruit a day. Moreover, fruit juice is not an adequate substitute because the fruit 7 contains more fiber and vitamins than juices, which are usually high in sugar and contain preservatives. Hu says primary school students should be encouraged to eat one or two fruits every day. 8 many students found they didn't have time to eat fruit before breakfast or in the evening, they should be encouraged to 9 to school and eat it during class breaks . Finally, she suggests that parents encourage their children to eat fruit, instead of forcing them. Ma Guansheng, deputy 10 of the CDC's Nutrition and Food Safety Institution(营养和食品安全机构), says: "6-12 years old is a crucial time for physical development. Children at this age need an adequate and balanced nutritional supply to guarantee the normal growth of the body." | |||
