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.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.
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. However, concerns about the negative health effects resulting from the consumption of a "junk food"-heavy diet, especially obesity, have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries.
