Junk food is a pejorative term for cheap food containing high levels of calories from sugar or fat with little fiber, protein, vitamins or minerals.[1][2][3] Junk food can also refer to high protein food like meat prepared with saturated fat -which some believe may be unhealthy, although some studies have shown no correlation between saturated fat and cardiovascular diseases;[4] many hamburger outlets, fried chicken outlets and the like supply food considered as junk food.[5][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.[6] 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
