Junk food is a term describing food that is unhealthy and/or has poor nutritional value, according to the Food Standards Agency (UK). The term is believed to have been coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972.^[1] The term has since become common usage.

Junk food often contains high levels of saturated fat, salt, or sugar and numerous food additives such as monosodium glutamate and tartrazine; at the same time, it is lacking in proteins, vitamins and fibre, among other healthy attributes. It is popular with suppliers because it is relatively cheap to manufacture, has a long shelf life and may not require refrigeration. It is popular with American consumers because it is easy to purchase, requires little or no preparation, is convenient to consume and has lots of flavor. Consumption of junk food in America, has been associated with obesity, heart disease, Type 2 diabetes and dental cavities. There is also concern about the targeting of marketing to children.

Classification

What constitutes unhealthy food may be confusing and, according to critics, includes elements of class snobbery, cultural influence and moral judgement. For example, fast food in North America, such as hamburgers and french fries supplied by companies such as McDonald's, KFC and Pizza Hut are often perceived as junk food, whereas the same meals supplied by more up-market outlets such as California Pizza Kitchen or Nando's are not, despite often having the same or worse nutritional content.^[1] Some foods that are considered ethnic or traditional are not generally considered junk food, such as falafel, pakora, gyoza or chicharron, though all of these foods have little nutritional value and are usually high in fat from being fried in oil. Other foods such as white rice, roast potatoes and processed white bread are not considered junk food despite having limited nutritional content compared to wholegrain foods. Similarly, breakfast cereals are often regarded as healthy but may have high levels of sugar, salt and fat.^[1]

Some types of chips that are said to be "junk food" may actually be partially harmful because they may contain polyunsaturated and monounsaturated fats. It should also be understood that the detrimental effects of the empty calories may outweigh the benefits of the unsaturated fats^{[citation needed]}. These foods tend to be high in sodium, which may contribute in causing hypertension (high blood pressure) in some people.

Marketing

During 2006 in the United Kingdom following a high profile media campaign by the chef Jamie Oliver and a threat of court action from the National Heart Forum^[1], the UK advertising regulator and competition authority, Ofcom, launched a consultation on advertising of foods to children.^[1] The Food Standards Agency was one of many respondents.^[1] As a result a ban on advertising during children's television programmes and programmes aimed at young people was announced.^[1] The ban also includes marketing using celebrities, cartoon characters and health or nutrition claims. Some schools have tried to ban junk food.
