Junk food

Junk food is a term used to describe food that is high in calories from macronutrients such as sugar and fat, and often also high in sodium, making it hyperpalatable, and almost always low in dietary fiber, protein, or micronutrients such as vitamins and minerals. It is also known as high in fat, salt, and sugar food (HFSS food). The term junk food is a pejorative dating back to the 1950s. Precise definitions vary by purpose and over time. Some high-protein foods, like meat prepared with saturated fat, may be considered junk food. Fast food and fast-food restaurants are often equated with junk food, although fast foods cannot be categorically described as junk food. Candy, soft drinks, and highly processed foods such as certain breakfast cereals, are generally included in the junk food category; much of it is ultra-processed food. Concerns about the negative health effects resulting from a junk food-heavy diet, especially obesity, have resulted in public health awareness campaigns, and restrictions on advertising and sale in several countries. Current studies indicate that a diet high in junk food can increase the risk of depression, digestive issues, heart disease and stroke, type 2 diabetes, cancer, and early death.

Etymology The term junk food dates back at least to the early 1950s, although its coinage has been credited to Michael F. Jacobson of the Center for Science in the Public Interest, in 1972. In 1952, the phrase appeared in a headline in the Lima, Ohio, News, "'Junk Foods' Cause Serious Malnutrition", over a reprint of a 1948 article from the Ogden, Utah, Standard-Examiner, originally titled, "Dr. Brady's Health Column: More Junk Than Food". In the article, Dr. Brady writes, "What Mrs. H calls 'junk' I call cheat food. That is anything made principally of (1) white flour and or (2) refined white sugar or syrup. For example, white bread, crackers, cake, candy, ice cream soda, chocolate malted, sundaes, sweetened carbonated beverages." The term cheat food can be traced back in newspaper mentions to at least 1916.

Definitions In Andrew F. Smith's Encyclopedia of Junk Food and Fast Food, junk food is defined as "those commercial products, including candy, bakery goods, ice cream, salty snacks and soft drinks, which have little or no nutritional value but do have plenty of calories, salt, and fats. While not all fast foods are junk foods, many of them are. Fast foods are ready-to-eat foods served promptly after ordering. Some fast foods are high in calories and low in nutritional value, while other fast foods, such as salads, may be low in calories and high in nutritional value." Junk food provides empty calories, supplying little or none of the protein, vitamins, or minerals required for a nutritious diet. Some foods, such as hamburgers, and tacos, can be considered either healthy or junk food, depending on their ingredients and preparation methods. The more highly processed items usually fall under the junk food category, including breakfast cereals that are mostly sugar or high fructose corn syrup and white flour or milled corn. Junk food can be defined through nutrient profiling. The United Kingdom's Advertising Standards Authority, the self-regulatory agency for the UK ad industry, takes this approach. Foods are scored for "A" nutrients (energy, saturated fat, total sugar, and sodium) and "C" nutrients (fruit, vegetable, and nut content, fiber, and protein). The difference between A and C scores determines whether a food or beverage is categorized as HFSS (high in fat, salt and sugar; a term synonymous with junk food). Defining junk food as highly processed or ultra-processed food mainly considers the level of processing rather than nutrient profiles. In Panic Nation: Unpicking the Myths We're Told About Food and Health, the junk food label is described as nutritionally meaningless: food is food, and if there is zero nutritional value, then it is not a food. Co-editor Vincent Marks explains, "To label a food as 'junk' is just another way of saying, 'I disapprove of it.' There are bad diets – that is, bad mixtures and quantities of food – but there are no 'bad foods' except those that have become bad through contamination or deterioration."

History In 2010 the New York Times described the history of junk food as "a largely American tale: It has been around for hundreds of years, in many parts of the world, but no one has done a better job inventing so many varieties of it, branding it, mass-producing it, making people rich off it and, of course, eating it." Cracker Jack, the candy-coated popcorn-and-peanuts confection, is credited as the first popular name-brand junk food; it was created in Chicago, registered in 1896, and became the best-selling candy in the world 20 years later.
