Junk food is a derisive slang term for food that is of little nutritional value and often high in fat, sugar, salt, and calories.[1][2][3] It is widely believed that the term was coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972.[4]
Junk foods typically contain high levels of calories from sugar or fat with little protein, vitamins or minerals. Foods commonly considered junk foods include salted snack foods, gum, candy, sweet desserts, fried fast food, and sugary carbonated beverages. [5] Many foods such as hamburgers, pizza, and tacos can be considered either healthy or junk food depending on their ingredients and preparation methods with the more highly processed items usually falling under the junk food category. [6] What is and is not junk food can also depend on the person's class and social status, with wealthier people tending to have a broader definition while lower-income consumers may see fewer foods as junk food, especially certain ethnic foods.
Despite being labeled as "junk" consuming such foods usually does not pose any immediate health concerns and is generally safe when integrated into a well balanced diet.[7][8]
The high levels of fat and sodium in junk food and fast food can contribute to heart disease by raising blood cholesterol levels and contributing to arterial plaque build up. The high levels of trans fatty acids found in many junk foods and fast foods can lead to fatty liver deposits, which, over time, can cause liver dysfunction and disease.
