摘要：Dear Editor-in-Chief: Although there is no agreement on the definition for the term of fast food, it is mainly defined as "easily prepared processed food served in snack bars and restaurants as a quick meal or to be taken away". Over the past two decades, an increasing trend in global fast food marketing and a public interest for consuming of take-away foods has developed. Fast foods are quick, convenient, relatively inexpensive, and liked by people of most different age groups; they are rich in highly processed meat and refined carbohydrate, sodium, total fat, saturated and trans fatty acids, cholesterol, and poor in essential nutrients and dietary fibers.
