Junk food is defined as foods that are easily available, generally cheap and have less nutritional value. The term junk food has existed since the early 1970s, when the Center for Science in the Public Interest began using it to raise awareness about foods it considered unhealthy. While not everyone agrees on what foods should be considered junk food, the term is generally used to describe foods that are high in calories and low in nutrients. Junk food tends to contain large amounts of fat, sugar, and salt.
Junk food also tends to be processed, meaning that it typically contains artificial flavors and additives, and is packaged in boxes, cans, or bags. Several countries have taken, or are considering, various forms of legislative measures to curb the consumption of junk food.
