Early Origins of Overeating: Early Habit Formation and Implications for Obesity in Later Life

Excessive eating is a major determinant of the present obesity epidemic. Early infancy is a critical period in food preference formation and habits established in this period track into adulthood. This behavior is learned though repeated experiences with foods. Many mechanisms influence children’s eating patterns and overall energy intake. In this review we focus on food preference formation, the food itself, and environmental factors related to the eating situation. We will highlight some of the many possible actions that are available to parents and practitioners to facilitate eating behavior supporting healthy diets in children. The plasticity of food preferences underlines the importance of parents’ and caregivers’ continuous efforts in helping children develop healthy eating patterns. It is never too late, but starting in early infancy holds many advantages.
