Fast food develops fast nowadays because it is economic，convenient and there are kinds of food meet different flavors. It will become more and more popular in the future.
However，I don't think eating too much fast food is good for our health. Fast food may cause illness. I admit that fast food is cheap and convenient. You can fill your stomach easily without paying too much. And you don't have to pretend to be graceful when you do want to. Different flavours meet different tastes. You can decide what you want to eat. But every coin has two sides. Fast food also has troubles. The most worrying one is whether fast food is clean or not. In order to gain a greater profit，some snack bars try every means to reduce the cost.Some even adopts illegal means. As is reported on TV and newspaper， many snack bars use some dirty refined oil to cook the meals. It is not easy for the customers to be aware of what they are eating. Usually there will be lots of bacteria in such kind of oil. These bacteria can cause deadly diseases， such as cancer. The customers become victims of the snack bars. Maybe you will ask，"What about KFC or Mc Donald's? The sanity equipments are good in these restaurants." My suggestion is that you'd better eat less. Foods in KFC and Mc Donald's contain much fat. They also cause health problems.Eating too much fried chicken， fried chips，hand burgs and something else may make you fat.
In a word，I don't suggest people eat too much fast food.You have much to concern about when you are having fast food. To keep healthy，we have to pay attention to our habit of diet.

快餐的發展很快，因為它是經濟，方便，有各種各樣的食物，滿足不同口味。它將在未來變得越來越流行。
然而，我不認為吃太多快餐對我們的健康有好處。快餐食品可能導致疾病。我承認快餐很便宜，也很方便。你可以很容易地填滿你的肚子而不付出太多的付出。你不必假裝優雅，當你想。不同的口味滿足不同的口味。你可以決定你要吃什麼。但每個硬幣都有兩面。快餐也有麻煩。最令人擔心的是快餐是否乾淨。為了獲得更大的利潤，一些小吃店想盡一切辦法來降低成本，有的甚至至採取非法手段。正如在電視和報紙上報導的那樣，許多快餐店使用一些骯髒的精煉油來烹調食物。顧客不容易知道他們在吃什麼。通常會有大量的細菌在這種油。這些細菌會導致致命的疾病，如癌症。顧客成為快餐店的受害者。也許你會問，“肯德基和唐納德的好嗎?在這些餐館裡的衛生設備都很好。”我的建議是你最好少吃點。肯德基和唐納德的食物中含有大量的脂肪。他們也會導致健康問題。吃太多的炸雞，炸薯條，一方面城市和其他的東西可能會使你發胖。
一句話，我不建議人們吃太多快餐，當你吃快餐的時候，你有很多要關心的問題。為了保持健康，我們必須注意我們的飲食習慣。
