RESUMEN
Abstract@#Children and adolescents are at an important stage in the development of eating habits and food skills. Nutrition literacy is inseparable from healthy eating behaviors and higher nutritional quality, and improving nutrition literacy is an important pathway to better nutrition. The paper summarizes domestic and international research on nutrition literacy from the perspectives of definition and assessment tools in children and adolescents. It is found that there is no universal definition of nutritional literacy. Adult nutrition literacy or with appropriate adjustments are widely used in children and adolescents, without taking into account the unique developmental characteristics and nutritional needs of children and adolescents; the measurement tools of nutritional literacy are diverse, and there is no unified assessment tools, so it is difficult to compare and analyze research findings and draw reliable conclusions. In the future, authoritative definitions, and standardized evaluation tools are in great need.
