Have you ever thought about why you eat what you eat? Is it because it’s tasty? Healthy? Trendy? There are many factors that influence what an adolescent eats. But health is not always the most important one. We wanted to better understand these factors. So we did a scientific review of surveys and studies to see what adolescents eat worldwide. We also explored how economic status and food environment affect food choices. We learned that many adolescents value food as a way to express their individuality. It also gives them a sense of belonging with their peers. We also discovered that limited access to healthy food is a problem in many areas. So are advertisements promoting unhealthy food. That is why countries all over the world need nutrition programs that make healthy food more available, affordable, and appealing to adolescents.
