Junk food
Junk food is a term describing food that is perceived to be unhealthy or having poor nutritional value. 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 become common usage amongst many different groups over the years, including opponents of fast food industries and environmentalists. Junk food typically contains high levels of 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 fiber, among others. 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 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 is associated with obesity, heart disease, Type 2 diabetes and dental cavities. There is also concern about the targeting of marketing at children.
What is a junk food?
What constitutes a junk food may be confusing and according to critics may include elements of class snobbery and moral judgement. For example, fast food such as hamburgers, pizza and french fries supplied by companies such as McDonalds, KFC and Pizza Hut are often perceived as junk whereas the same meals supplied by more upmarket outlets such as Pizza Express or Nando's are not despite often having the same or worse nutritional content.[1] Other foods such as Foie Gras, Duck L'Orange, roast potatoes and bread are not considered junk food despite having limited nutritional content. Similarly, whilst candy[2] Breakfast cereals are often regarded as healthy but may have high levels of sugar, salt and fat.[3] Many critics believe that junk food is not harmful when consumed as part of a balanced diet and some believe that the term should not be used at all.[4]
Effects
Once children start consuming junk foods, their intake of high-protein-vitamins-roughage diet substantially decreases and intake of milk and healthy fruit juices is replaced by soft drinks. This can cause a deficiency of calcium, milk being a rich source of calcium, resulting in weakening of bones.
Some types of chips that are said to be "junk food" may actually be partially beneficial because they may contain polyunsaturated and monounsaturated fats. However, since they are fats, the intake of these should be kept to a minimum. It should also be understood that the detrimental effects of the empty calories may outweigh the benefits of the unsaturated fats. These foods tend to be high in sodium, Ówhich 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[5], the UK advertising regulator and competition authority, Ofcom, launched a consultation on advertising of foods to children.[6] The Food Standards Agency was one of many respondents.[7] As a result a ban on advertising during children's television programmes and programmes aimed at young people was announced.[8] The ban also includes marketing using celebrities, cartoon characters and health or nutrition claims.
