Junk food is a pejorative term for food containing high levels of calories from sugar or fat with little protein, vitamins or minerals. Use of the term implies that a particular food has little "nutritional value" and contains excessive fat, sugar, salt, and calories.[1][2][3] Junk food can also refer to high protein food like meat prepared with saturated fat -which some believe may be unhealthy[citation needed]; many hamburger outlets, fried chicken outlets and the like supply food is considered as junk food.[4][better source needed]
Despite being labeled as "junk," such foods usually do not pose any immediate health concerns and are generally safe when integrated into a well balanced diet.[5] However, concerns about the negative health effects resulting from the consumption of a "junk food"-heavy diet have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries.
