Effects of Junk and Nutritious Foods to the Health of the Students

Chapter 1
Introduction

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.

Life today is not like how it was before. A long time ago, people ate food that was very good for their health. They ate food not contains chemicals, preservatives, artificial colours, and flavours. People also spent a lot of time cooks their own foods. Therefore, those people were not affected by the food that they ate, because all the foods that they had was natural and healthy. That is, they did not have any problems with their health. Foods can be classified into two types: junk food and healthy food. The next few paragraphs will make comparisons and contrasts between healthy food and junk food. Initially we will focus on junk food then healthy food.

Junk food is simply an unhealthy food, food with poor nutritional value; junk food contains very high fat and sugar. But healthy food is rich with nutritional value. Also junk food has preservatives, chemicals, artificial colours and flavours. But healthy food is not containing these substances. However, both junk food and healthy food are delicious but junk food has more delicious than healthy food. However, junk food has affected the body's health and causes dangerous diseases, such as obesity, diabetes, high blood pressure and sometimes poisoning. On the other hand, healthy food preserves and protects a body from diseases.

Both junk food and healthy food are resembled in preparation time and they have alike cost. Junk food can be found in fast foods, frozen foods and other foods which have chemical contents. In contrast, healthy food is fruits, vegetable, meat, nuts, seafood and dairy food. Also junk food contains less or sometimes no proteins, vitamins and fibre. This is different from healthy food; it contains high proteins, vitamins and fibre.

Chapter 1
INTRODUCTION

“Health is wealth” is a very common quotation that people didn’t care about its meaning. But for us, it has a great sense especially in this kind of life we have at present. Life today is not like how it was before. A long time ago, people ate food that was very good for their health. They ate food that does not contain chemicals, preservatives, artificial colors, and flavors. People also spent a lot of time cooks their own foods. Therefore, those people were not affected by the food that they ate, because all the foods that they had was normal and healthy. That is, they did not have any problems with their health. Foods can be classified into two types: unhealthy food which is also known as junk food and healthy food or what we called nutritious food.

A. Background of the Study

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. This study 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. We are curious on what is going on around us. Some teenagers and children don’t eat a lot of nutritious foods because their bodies are craving for delicious and enticing for junk foods.

B. Statement of the Problem

Specifically, it seeks to answer the following questions:

1. What are the effects of eating junk foods in the eating habits? 2. What are the diseases that we can get from eating unhealthy foods? 3. What makes a junk food “junk food”? 4. What health benefits we can acquire from eating nutritious foods? 5. Why is it that most people especially children demand for junk food instead of nutritious ones?

C. Significance of the Study

This study seeks to determine the food contents do junk foods have that nutritious don’t, which make it more appealing to people especially children, show the different diseases they can get from eating such unhealthy foods, the health benefits they can get from eating nutritious foods, and to encourage people to consume only healthy foods.

In the researchers’ study, the possible hypotheses are that one of the diseases that consumers can get from eating junk foods is ulcer. It can greatly affect their eating habits because in consumption of this, they will lose their appetite.
