Teenagers today are becoming addicted to fast food without realizing the effects. As they have been surrounded by junk food all of their lives so it is really the only type of food that they have ever known. People who lived one hundred years ago did not grow up with junk food so they are used to eating healthy food. Because of the advertisements shown on television, the many fast food restaurants to attend, and the fact that teenagers can obtain food whenever they are hungry is a real disaster for the whole community. Thus I am absolutely against teenagers eating junk food. By eating junk food, a teenager will not get any nutrients required for proper functioning of the body. This means that the teenager will always be tired and fatigued to do any work. Also teenager will feel constantly hungry and weak due to imbalance created by the junk food. Junk food is full of fat and calories; a lot more than what is required for the body on a daily basis. This will get converted to fat deposit in the body, which will certainly affect the body shape. Eating healthy should be on the top of the teenagers’ priority list as they are always considered about having a good figure to being more successful. In conclusion, teenagers should consider the fact that unhealthy diet like eating junk food can lead to many health problems like high blood pressure heart disease. Parents should also be able to advise their children and guide them to a healthy life style as they are responsible about protecting their children from junk food dangerousness.
