KEEPING fit requires a combination of healthy eating and regular exercise. On the second of these at least, the world’s food companies can claim to be setting a good example: they have been working up quite a sweat in their attempts to fend off assaults by governments, consumer groups and lawyers who accuse them of peddling products that encourage obesity. This week saw the unveiling of another industry initiative: five leading food producers—Danone, Kellogg, Nestlé, Kraft and PepsiCo—introduced a labelling scheme for the British market which will show “guideline daily amounts” for calories, fats, sugar and salt on packaging. The new labels will start to appear on the firms’ crisps, chocolate bars, cheese slices *and the like[2] over the next few months. A number of other food giants, such as Cadbury Schweppes and Masterfoods, have already started putting guideline labels on their products.

　　将健康的饮食习惯和经常性的锻炼二者结合才可以让身体保持健康。至少就第二点而言，全球的食品公司可以说是树立了一个很好的典范：为了避开政府、消费者团体以及律师们的抨击——指责食品公司四处兜售促进肥胖的产品，他们已经累得大汗淋漓了。本周，食品业的另一举措也公诸于世：五家业内领先的食品厂商——Danone, Kellogg, Nestlé, Kraft以及PepsiCo——在英国市场实施了一项商品标注计划，即在包装上标明卡路里（热量）、脂肪、糖和盐的“每日摄入量指南”。在接下来的几个月里，这些食品公司的土豆条、巧克力棒、干酪片等等包装上将开始出现这类新标注。其它许多食品业巨头如Cadbury Schweppes 和Masterfoods也已经着手在其产品上加入指导性标记。
