Fast food is quite popular in China these years.Many people, mainly children and teenagers, like to have fast food for their meals. Why is fast food so welcomed by people? I think there are three reasons.
　　First of all, fast food is very convenience. With busy lifestyles, people tend to rely on fast food to save their time. Besides, we can either have our meals in the restaurant or take it home, which means we have more choices than waiting in the crowded common restaurant only. What's more, the environment of the fast food resaurant such as the small coffee shops is clean and comfortable, which often creates a romantic and elegant atmosphere.
　　However, just like every coin has two sides, fast food also has its own drawbacks. For example, compared with vegetables and fresh fruits, fast food contain little nutrients that are good for our health. Instead, fast food like hamburgers and French fries are rich in fat, and we will easily put on weight if we eat woo much of them. That's why we have more overweight children than before.
　　In conclusion, although fast food is delicious and convenience, we should eat them neither too often nor too much in order to keep ourselves in good health.
