1. Junk food is a term describing food that is perceived to be unhealthy or having poor nutritional value, according to Food Standard Agency. The term is believed to have been coined by Michael Jacobson, Director of the Centre for Science in the public interest, in 1972. The term has since become common usage. 2. Junk food typically contains high level 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 fibre, among others, 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 and has lots of consumers because it is easy to purchase, requires little or no preparation, convenient to consume and lots of flowers. Consumption of junk food is associated with obesity, heart disease, Type 2 Diabetes and dental cavities. There is also concern about the targeting of the marketing at children. 3. What constitutes a junk food may be confusing and according to critics, includes elements of class snobbery and moral judgment. For example, fast food such as hamburgers and French fries supplied by companies such as Mcdonald’s , KFC and Pizza Hut are often perceived as junk foods whereas same meals supplied by more up-market outlets such as Pizza Express or Nando’s are not despite often having the same or worse nutritional content. Other food such as Foie Gras, roast potatoes and bread are not considered junk food despite having limited nutritional content. Similarly, breakfast cereals are often regarded as healthy but may have high level of sugar, salt and fat. Many critics believe that junk food is not harmful when consumed as part of balanced diet and some believe that the term should not be used at all. 4. Should a child start consuming junk foods exclusively, as opposed to having a balanced diet, their intake of high-protein-vitamins-roughage diet would substantially decrease and intake of milk and healthy fruit juices would likely to be replaced by soft drinks? This would potentially lead to a deficiency of calcium, milk being a rich source of calcium, resulting in weakening bones. Some type of chips that are said to be “junk foods” may actually be.
