    Do you eat the right food?

    Stephen Robinson, a government adviser on food and diet, is worried about the diet of young British people today. In a recent statement he said that young people in the UK ate too much junk food（不利健康的小吃）. He added that young children especially didn’t eat enough fruit and vege tables. One inventive（有创造力）food company has started to produce a range（一系列）of vegeta- bles with “trendy” flavours—to make them more attractive to children.

    The government is now preparing to carry out a food survey（调查）of young people. It is training interviewers to visit young people at home or at school and discuss their diet with them, and also to show them how to prepare a “food diary” for seven days. The idea is that the govern- ment can then find out exactly what is in the diet of young people. If necessary, they can then encourage young people to include the right balance of protein（蛋白质）, fat, and carbohydrat（碳水化合物）in their diet. Perhaps we will have a healthier population in the future!
