Influence of food texture on energy metabolism and adiposity in male rats

Early influences on development of sensory perception and eating habits

Infancy and early childhood are important periods for the development of food choices and eating preferences that are tracked into adult life influencing weight gain, body composition, metabolism, and ultimately affecting the balance between health and disease. In this narrative review, we aimed at discussing studies focused on the effects of fetal programming and early food experiences, highlighting recent advances in the discovery of factors that contribute to the development of food preferences and eating behavior. Food preference can be influenced by early direct contact with flavors, textures, and aromas, as well as by environmental adversities during early development. Evidence suggests that exposure to intrauterine growth restriction is associated with an increased preferences for highly palatable foods such as those rich in carbohydrates and fats over the life-course. Early flavor experiences, whether from amniotic fluid or human milk, may also shape the development of food preferences. Finally, children are more likely to accept textures that they are able to manipulate, and early exposure to a range of textures facilitates the acceptance of foods of various textures later on. Improving diet habits during gestation (fetal) and postnatal periods is of critical importance for the establishment of positive eating habits and healthy growth in infants and should be an important focus of primary prevention efforts.
