Many changes are taking place in American food styles. The United States is traditionally famous for its very solid and unchanging diet of meat and potatoes, Now, in addition to the traditional home-cooked meal, we have many different alternatives to choose from: such as nutrition-balanced health food, convenient and delicious fast food and so on.
Health food gained popularity when people began to think more seriously about their physical health. Health food includes natural food with minimal processing. Most health food enthusiasts are vegetarians. They eat no meat and prefer to get their essential proteins from other sources, such as beans, cheese, and eggs.
Fast food can be seen all over the country. Speed is a very important factor in the life of an American. People usually have a short lunch break or they just do not want to waste their time eating. Because fast-food restaurants are places which take care of hundreds of people in a short time, there is usually very little waiting. And the food is always cheap. 美国人的饮食习惯正在发生变化。美国人多年来那种丰盛的、一成不变的肉制品加土豆的传统餐，早已为世人所熟知。而今，我们美国人可以有多种不同的选择，除了传统的家常菜外，我们可以享受到各种各样的营养均衡的保健餐，方便可口的快餐等等。
保健食品因人们开始重视自身健康而倍受青睐。保健食品包括那些尽可能不加工的天然食品。大多数热衷于保健食品的人士属素食主义者。他们不吃肉类食物，更愿意从豆类、奶酪和鸡蛋等食物中获取人体所需要的蛋白质。 全国各地到处可见快餐店。速度是美国人生活中一个非常重要的因素。通常人们的午餐休息时间很短，或者人们不愿意在用餐上花费过多的时间。由于快餐店可以在很短的时间里向数以百计的客人供餐，人们通常不用等太久。而且，快餐还很便宜。
