Fast food is a type of mass-produced food that is prepared and served very quickly. It began with the first fish and chip shops in Britain in the 1860s. Drive-through restaurants were first popularized in the 1950s in the United States. The food is typically less nutritionally valuable compared to other foods and dishes. While any meal with low preparation time can be considered fast food, typically the term refers to food sold in a restaurant or store with preheated or precooked ingredients, and served to the customer in a packaged form for take-out/take-away. Fast food restaurants are traditionally distinguished by their ability to serve food via a drive-through. The term "fast food" was recognized in a dictionary by Merriam–Webster in 1951.
Outlets may be stands or kiosks, which may provide no shelter or seating, or fast food restaurants (also known as quick service restaurants). Franchise operations that are part of restaurant chains have standardized foodstuffs shipped to each restaurant from central locations.
According to the National Institutes of Health (NIH), fast foods are quick alternatives to home-cooked meals. They are also high in saturated fat, sugar, salt and calories.
Eating too much fast food has been linked to, among other things, colorectal cancer, obesity and high cholesterol.
The traditional family dinner is increasingly being replaced by the consumption of takeaway, or eating "on the run". As a result, the time invested on food preparation is getting lower and lower, with an average couple in the United States spending 47 minutes and 19 minutes per day on food preparation.
The concept of ready-cooked food for sale is closely connected with urban development. In Ancient Rome, cities had street stands - a large counter with a receptacle in the middle from which food or drink would have been served. It was during post-WWII American economic boom that Americans began to spend more and buy more as the economy boomed and a culture of consumerism bloomed. As a result of this new desire to have it all, coupled with the strides made by women while the men were away, both members of the household began to work outside the home. Eating out, which had previously been considered a luxury, became a common occurrence, and then a necessity. Workers, and working families, needed quick service and inexpensive food for both lunch and dinner. This need is what drove the phenomenal success of the early fast food giants, which catered to the family on the go (Franklin A. Jacobs). Fast food became an easy option for a busy family, as is the case for many families today.
