• Food containing high levels of calories from sugar or fat with little proteins, vitamins or minerals is known as junk food. Use of the term implies that a particular food has little nutritional value and contains excessive fat, sugar, salt, and calories. Junk food can also refer to high protein food like meat prepared with saturated fat which some believe may be unhealthy many hamburger outlets, fried chicken outlets and like supply food is considered as junk food. Unfortunately, today’s world has been adapted to a system of consumption of foods which has several adverse effects on health. Eating habits and forced many people to consume fancy and high calorie fast food, popularly known as Junk foods [1]. Junk food have poor nutritional quality as they don’t provide any protein, vitamins and minerals but only supply empty calories to our bodies. Thus, the excessive consumption of fast foods can lead to many nutritional deficiency diseases and can also result in obesity of life threatening condition. Regarding the opinion of respondents about nutritional values of fast foods, some of them agreed that they have poor nutritional standard while a majority disagreed to this [2]. There is a growing concern among policymakers and educators that junk food availability in schools is a significant contributor to the childhood obesity epidemic. Between 2003 and 2005, approximately 200 piece of legislation were introduced in US state legislatures to establish nutritional standards in schools or to address the availability of specific food items during school hours through any of the venues. These items included candy, high-fat salty snacks, low-fat salty snacks, high-fat baked goods, low-fat baked goods, ice-cream, milk, fruits/vegetables, bottled water, 100 percent juice, and soda pop or other beverages that are not 100 percent juice. The child food consumption questionnaire asked if sweets, salty snacks, and sweetened beverages could be purchased at the school during school hours. Based on these questions we constructed three alternate measures of competitive food availability in the school [3]. There are some 1.2 billion youths between 10-19 years of age or about 19 percent of the total global population. Adolescents go through intense physical, psychological, and cognitive development. Adolescents gain up to 50 percent of the adult weight, 50 percent of the adult’s skeletal mass and more than 20 percent of their adult weight. This growth needs maximum calorie and protein. Students attending schools in different socio-economic areas in Cape Town, South Africa revealed the result that 77.8 percent of the students have breakfast before school and 79.7 percent after school. Students, who attended schools of high socio-economic status, were twice as likely to bring unhealthy foods to school (FAO, 2014). In Nepal, most of the times these junk foods contains items that are laced with colours those are non-edible, carcinogenic and harmful to body. These foods and their colours can affect the digestive system, and others effects of it emerging after many years. The consumption of refined and processed food products lowers the nutritional status. General Tiffin items are puris, pakodas, samosa and other food items that are very high in trans-fat content. Especially, children and adolescents who have to eat their breakfast and Tiffin outside house are more exposed to having these food items. Hence, Children and adolescents are especially vulnerable to pour diets as they can slow the growth, decay new teeth, promote obesity, and sow the seed of non-communicable disease [4].

  Statement of the problem

  Junk food contributes to an increased risk of cardiovascular diseases, diabetes, weight gain, and many other chronic health conditions. Also consumers tend to eat too much at one sitting and consumers who have satisfied their appetite with junk food are less likely to eat healthy foods like fruits, vegetables, or dairy products. Junk foods consumption alters brain activity in a manner similar to addictive drugs like cocaine and heroin. After many weeks with unlimited access to junk foods, the pleasure centres 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.

  Objective of the study

  The main objective of this study is to find out the consumption of junk foods and its health effect on school students. However, the specific objectives of this study area are as follows:

  • To assess the demographic and socio-economic status of the parents;
  • To find out the situation and causes of junk food consumption by the respondents;
  • To identify the effect of junk food on the health of the respondents.
• 
  

Review of literature and research gap

Stated that the advertising media plays an active part in shaping children’s perception of the world, and their behaviour by cultivating acceptance of the beliefs, values and attitudes that it portrays at a broad cultural level; by social learning, whereby children come to learn which attitudes and behaviours are accepted and rewarded; and by its impact on the formation, development and maintenance of cognitive scripts for how to behave in a variety of circumstances [5]. Stated that junk food containing low nutritional value and high calories, sugar and fat, which of then lead to many life – threatening ailments. Junk foods typically contain high levels of calories from sugar or fat with little protein, vitamins or minerals. Food commonly considered junk foods include salted snack foods, gum, candy, sweet desserts, fried junk food and sugary carbonated beverage. Many foods such as hamburger, Pizza and tacos can be considered either healthy or junk food depending on their ingredients and preparation method with the more highly processed items usually falling under the junk food category. Mentioned that junk food simply means an empty calorie food [1]. An empty calorie food is a high calorie or calorie rich food which lacks in micro – nutrients such as vitamins, minerals, or amino acids, and fibre but has high energy. These foods don’t contain the nutrients that your body needs to stay healthy. Stated that though junk food at school may pose a health risk to some students susceptible to obesity [6]. Gorman further pointed out that the substitute foods allowed by official policies banning junk food and soda often allow products like fruit juice that contain just as many calories. He recommended that officials should consider a change in school food policies weigh the health costs borne by the fraction of students susceptible to obesity against the benefit conferred by the programs funded by in – school junk food sales.
