Fast food is becoming more and more popular in China,there is no one but loves to eat it, especially among children and teenagers. Today, there is no other thing can represents the fast pace of modern society than fast food does.( it's certainly difficult to think of any other single thing that represents the fast pace of modern society as powerfully as fast food.)

　　There are several reasons for its popularity. First(to begin with), it is very convenient and saves a lot of time. The trends of modern society seem to all point to one ultimate goal —— saving time, and fast food well serves this purpose. You just go into a fast food restaurant, order your food, and your food is ready in no time. You can either eat it there or take it away. Further, its popularity is also attributed to the clean and comfortable environment of fast food restaurants, the excellent service, and the guaranteed quality of food.

　　However, in terms of nutrition, fast food leaves much to be desired.(is far from satisfactory.) It usually does not compose a balanced diet and is low in nutritional value. Thus, doctors suggest that people, especially children, eat fast food as little as possible. 　　Although cooking at home is time — consuming and the following washing-up tiresome, it offers healthy and delicious meals your body likes and needs.

All in all,fast food is only a good choice when you are in a hurry and turn to it once in a while.
