History of Junk Food -

According to an article in the New York Times, "Let Us Now Praise the Great Men of Junk Food".

 "The history of junk food is 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.

Popularity and appeal

Junk food in its various forms is extremely popular, and an integral part of modern popular culture. In the US, annual fast food sales are in the area of $160 billion, compared to supermarket sales of $620 billion (a figure which also includes junk food in the form of convenience foods, snack foods, and candy). In 1976, "Junk Food Junkie", a US Top 10 pop song, described a junk food addict who pretends to follow a healthy diet by day, while at night gorges on Hostess Twinkies and Fritos corn chips, McDonald's and KFC.Thirty-six years later, Time placed the Twinkie at #1 in an article titled, "Top 10 Iconic Junk Foods": "Not only...a mainstay on our supermarket shelves and in our bellies, they've been a staple in our popular culture and, above all, in our hearts. Often criticized for its lack of any nutritional value whatsoever, the Twinkie has managed to persevere as a cultural and gastronomical icon.

America also celebrates an annual National Junk Food Day on July 21. 

Origins are unclear; it is one of around 175 US food and drink days, most created by "people who want to sell more food", at times aided by elected officials at the request of a trade association or commodity group. "In honor of the day," Time in 2014 published, "5 Crazy Junk Food Combination".
