This article reviewed the influencing factors on children's eating behaviors. The innate preference for sweet taste is generally recognized. Researches also showed that infants and young children can adjust their energy intake in response to the energy density of food. But neither infants nor young children have the ability to regulate nutrient intake according to their physiologically needs. Experiences and learning play major roles in the development of eating behavior as the children grow up. Social influences, such as parenting style and role model of parents, peers, teachers, and mass media all have significant effect on children's eating behavior.
