Some decide to leave off campus during their lunch time in order to eat something of their desire and this could be dangerous. The roads are not a safe place for teenagers, especially if they are in a hurry to get somewhere and if they are situated in the same vehicle as their friends. According to the author Alexa J. Karkenny, MD, an orthopedic resident at Jacobs Medical Center in New York City. "Accidents most frequently occurred when no parental supervision was present from the time of school dismissal ," (Keeping). If the schools allowed students to bring food from outside , they wouldn't have the desire to go out and eat during their lunch. Students wouldn't have to worry about being caught and worry that their food might be thrown away. Since outside foods are not allowed teachers follow the rules and when they witness outside food all they can manage to do is throw it away. This is unfair, especially because this food comes out of the money of either the student or the parent. Its basically throwing money away. That is why many students who don't enjoy the cafeteria food decide to go out and find something of their choice. Even so it's not like students bring a whole meal to school all they mostly have is a drink and some type of snack and some studies suggest that snacking can be beneficial towards people's health. " For some individuals, Including young children, snacking may have a positive rather than negative Impact on health and should not be discouraged on a population-wide basis. Depending on food choice, snacks and increased meal frequency could contribute to a healthy energy and nutrient intake and may have metabolic and cognitive benefits" (Miller). Thats is why the schools should allow students to bring foods from outside sources because it's beneficial for them. In a study done by Nutritional Assessment for Primary School Children in Teheran The snacks "Provided 38% of total energy intake by the students", (Amini).
