A. Background of the Study

Junk food is a derisive slang term for food that is of little nutritional value and often high in fat, sugar, salt, and calories.[1][2][3] It is widely believed that the term was coined by Michael Jacobson, director of the Center for Science in the Public Interest, in 1972.[4] Junk foods typically contain high levels of calories from sugar or fat with little protein, vitamins or minerals. Foods commonly considered junk foods include salted snack foods, gum, candy, sweet desserts, fried fast food, and sugary carbonated beverages. [5] Many foods such as hamburgers, pizza, and tacos can be considered either healthy or junk food depending on their ingredients and preparation methods with the more highly processed items usually falling under the junk food category. [6] What is and is not junk food can also depend on the person's class and social status, with wealthier people tending to have a broader definition while lower-income consumers may see fewer foods as junk food, especially certain ethnic foods. Despite being labeled as "junk" consuming such foods usually does not pose any immediate health concerns and is generally safe when integrated into a well balanced diet. [7] [8] http://en.wikipedia.org/wiki/Junk_food

Healthy food is better than junk food 

We are living in an age of MacDonald, KFC and star bucks where it becomes too hard to resist the tantalizing offers of pizzas, burgers, French fries and other appealing stuff these food chains have to offer. The healthier alternatives of food, such as fresh fruits, vegetables, lean meat and whole grains are too unappealing to ignite such a craving and finally preference for eating. However, increasing obesity among teens, heart problems, eating disorders and new researches call for our attention. The paper discusses healthy and junk food choices, their impact on human body and mind in addition to some animal researches and concludes that healthy food is certainly better than junk food.

A study by Paul Johnson and Paul Kenny at the Scripps Research Institute (2008) suggested that junk food consumption alters brain activity in a manner similar to addictive drugs like cocaine or heroin.[9] After many weeks with unlimited access to junk food, the pleasure centers of rat brains became desensitized, requiring more food for pleasure. After the junk food was taken away and replaced with a healthy diet, the rats starved for two weeks instead of eating nutritious fare.[10] A 2007 British Journal of Nutrition study found that female rats who eat junk food during pregnancy increased the likelihood of unhealthy eating habits in their offspring.[11] A report published in the Journal of the Federation of American Societies for Experimental Biology suggests that babies of mothers with a high-sugar and high-fat diet while pregnant are more prone to junk food themselves. The study was conducted on rats and suggests that "infants whose mothers eat excessive amounts of high-fat, high-sugar junk foods when pregnant or breastfeeding are likely to have a greater preference for these foods later in life."[12] 1. ^ Johnson, Paul M.; Kenny, Paul J.
