Early Influences on Development of Sensory Perception and Eating Habits.

How food preferences take shape before and after birth

The foods we enjoy become familiar through repeated experience, but that learning starts earlier than a child’s first solid meal. This review brings together evidence on how conditions in the womb, exposure to flavors and the development of chewing and texture skills help shape eating habits.

Flavor learning begins early. Flavor involves taste and smell together. Compounds from the maternal diet can reach the amniotic fluid and later human milk, allowing infants to encounter aspects of the surrounding food culture before eating those foods themselves. Studies reviewed here suggest that these early encounters can influence later acceptance. Familiarity helps explain why food preference is partly learned and why infants retain considerable capacity to develop preferences suited to their environment.

Texture requires experience as well as sensory acceptance. A child has to learn how to move, chew and swallow foods with different physical properties. The review describes links between early exposure to varied textures, the development of oral motor skills and acceptance of textures later in childhood. This expands the discussion beyond whether a food tastes pleasant: a food may also be rejected because its texture is unfamiliar or difficult to manage.

Prenatal growth may influence the reward value of food. A separate body of human and animal research links restricted fetal growth with later preferences for highly palatable foods, including foods rich in fat or carbohydrate. The proposed explanation involves developing systems that regulate energy needs, stress and reward. These biological influences can interact with the flavors, textures and foods available after birth.

The review therefore treats eating habits as a developmental process with several entry points. Nutritional conditions before birth, opportunities for sensory learning and the practical experience of eating all contribute. It argues for attention to this early period when studying how durable food preferences form. As a narrative review, it integrates diverse studies rather than testing one feeding intervention or establishing that a particular early experience determines a child’s eventual diet.
