时代新语：什么是“替餐”

　　小时候曾经听说过美国有些人白天就吃一顿饭，其它两餐都是吃个药丸就解决了。当时觉得这个事情听着特别不靠谱，药丸怎么能当饭吃呢？如今再说起这个话题，我就不得不感叹科学技术的伟大力量了。原来真有可以当饭吃的营养药啊。
　　As the name suggests, meal replacements can replace a regular meal. They're a quick and convenient way to get a lot of high quality protein, carbohydrates, and a host of other important nutrients. You can get meal replacement powder, bars, and shakes.
　　“替餐”，顾名思义，就是能够代替常规饮食的东西，它们能够快速又便捷地为人体提供大量高蛋白、碳水化合物以及其它重要营养素。常见的形式有替餐粉、替餐棒以及替餐奶昔。
　　For example, a meal of six baby carrots and a turkey sandwich on whole-wheat bread with mustard and dark green lettuce is just as healthy as a 220-calorie meal replacement shake.
　　比如说，一份220卡的替餐奶昔，其营养价值跟一顿饭吃6个小胡萝卜加一个放了芥菜和生菜的全麦火鸡三明治是一样的。
　　With meal replacement supplements, you can substitute some meals and still get a nutritious and balanced meal. People who are trying to lose weight use meal replacement to have a balanced diet and cut down on calories.
　　人们可以用替餐补充剂来代替某顿饭，同时又能保证饮食的营养均衡。想减肥的人们会用替餐来保证节食过程营养均衡同时减少热量的摄入。
