Junk food

 Junk food is an informal term for food that is of little nutritional value and often high in fat, sugar, and calories.
It is widely believed that the term was coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972.
Junk foods typically contain high levels of calories from sugar or fat with little protein, vitamins or minerals. Common junk foods include salted snack foods, gum, candy, sweet desserts, fried fast food, and carbonated beverages
