National Junk Food Day is celebrated on July 21st of each year. The staff at National Whatever Day was unable to discover the origin of National Junk Food Day.
Junk food is an informal term applied to some foods that are perceived to have little or no nutritional value (i.e. containing “empty calories”); to products with nutritional value, but also have ingredients considered unhealthy when regularly eaten; or to those considered unhealthy to consume at all. The term was coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972.
Junk foods are typically ready-to-eat convenience foods containing high levels of saturated fats, salt, or sugar, and little or no fruit, vegetables, or dietary fiber; and are considered to have little or no health benefits. Common junk foods include salted snack foods like chips (crisps), candy, gum, most sweet desserts, fried fast food and carbonated beverages (sodas) as well as alcoholic beverages. High-sugar cereals, particularly those targeted at children, such as Froot Loops, are also classified as junk food.
