The term “junk food” is used to describe food that is low in nutritional value, with a comparatively high caloric value. Many people try to avoid or limit such food in their diets, out of concerns that it is not healthy, despite the fact that numerous food manufacturers produce a range of products which could be considered junk. Nutritionists, doctors, and other health advocates often work to educate people about junk food, encouraging them to eat well balanced diets which contain a high proportion of healthy foods.
This term was coined in 1972 by advocates at the Center for Science in the Public Interest who wanted to raise public attention about the issue of foods with a high caloric value and a low nutritional value. For manufacturers, producing such foods has great appeal, as they tend to be cheap to make and easy to handle. They also have an extended shelf life, making them easy for stores to stock and sell.
Foods which fall under the umbrella of “junk food” vary, depending on a number of factors. Snack foods like chips, candies, and so forth are generally universally agreed upon as fitting in this category, and some people also lump fast food like hamburgers, pizza, and fries into the group. In some communities, ethnic takeaway food like gyros, Indian curries, tacos, fish and chips, and so on is also considered to be junk food.
Often, the foods which someone considers to be junk food are very telling. Definitions tend to hinge on someone's class and social status. People with more money tend to have a broader definition, causing some people to accuse them of class snobbery, while lower-income individuals may recognize fewer foods as junk food. Especially in the case of ethnic foods, a classification as “junk food” could be perceived as rather offensive, given that such foods have been prepared and consumed for centuries, and many are actually quite healthy.
As a general rule, no matter what one classifies as junk food, such foods are perfectly safe to eat, as long as they are integrated into a well-balanced diet. There's nothing wrong with having some potato chips now and then, but consuming a diet based primarily on such food is a cause for concern. Because junk food often lacks useful vitamins and minerals, people who eat it exclusively may suffer from nutritional deficiencies that could cause health problems, and they may experience other physical issues like indigestion as a consequence.
In some regions of the world, advertising of junk food is carefully controlled and monitored, out of the concern that such foods often appeal to children. Advertisers may be specifically prohibited from making advertising which targets children, for example, and any claims made about the nutritional benefit of foods are typically closely evaluated to determine how factual they are.
JUNK FOOD DIET
The junk food diet is a type of eating plan where dieters eat smaller portions or low fat versions of the junk foods they enjoy, for the purpose of losing weight. The junk food diet is not often recommended by doctors or dietitians, but many people attempt this diet so they can continue to eat their favorite unhealthy foods while losing weight. There is certainly no shortage of options at the grocery store for reduced fat or fat free versions of many favorite snack foods.
Junk food is typically considered to be sugary or fatty heavily processed foods. This includes items such as chips, cookies, candy, ice cream, and soda, just to name a few. Manufacturers now make low fat chips, fat free ice cream, and diet soda, among other variations. In addition, pre-measured packs allow dieters to more easily maintain portion control. For instance, small packs of cookies that are individually packaged and 100 calories each are very popular in this diet.
The trade-off when consuming a junk food diet made up of these foods is that most of them are heavily processed to begin with, and the reduced fat...
