Abstract
Prevalence of overweight and obesity is on the rise among children and adolescents. Compared to 2011, a 4-fold increase in prevalence of overweight and obesity was observed in 2024 with an estimated pool of prevalence of 24.0%. Evidence suggests that effective food labels help consumers to make quick and easy decisions on healthy and less healthy products based on the key nutrients such as sodium, fat, saturated fat, and sugar content. Currently, no reviews have been published on multiple traffic light (MTL) food labels as a tool used to prevent obesity among students. This review focuses on dietary behavior among students when exposed to MTL and includes an analysis of 19 papers by authors from around the world. The analysis showed that a more salient type of food label called MTL demonstrated to be superior in perceived healthfulness of food products and purchased intention compared to other food labels used among students. Therefore, educational institutional should be the primary setting in promoting healthy eating behaviors which is recognized in reducing obesity risks due to time spent in first 2 decades of their life.
